<pre style="white-space: pre;">
This is the symbolic and commented source code for the DSM E931
and E932 ECU. To assemble "standard_E932_E931_source.asm",
download the telemark assembler TASM from http://home.comcast.net/~tasm/ to the same directory and execute asm.bat from the DOS prompt.
The assembler will produce two files: standard_E932_E931_source.lst
is a line by line listing of the assembly with addresses while standard_E932_E931_source.obj is the 32KB binary image to burn
on EPROM. Default setting produces the E931 standard binary image
Required file, not provided (from http://home.comcast.net/~tasm/): TASM.EXE, Version 3.2
Contents: standard_E932_E931_source.asm
Assembly source file for the E931/E932. See notes at the beginning of that file for more details. Default setting produces the standard E931 EPROM image.
asm.bat
Batch file to assemble standard_E932_E931_source.asm
standard_E931.bin
Binary file read from an actual E931 EPROM. Assembly of standard_E932_E931_source.asm using the "E931" setting should produce an identical binary.
standard_E932.bin
Binary file read from an actual E932 EPROM. Assembly of standard_E932_E931_source.asm using the "E932" setting should produce an identical binary.
standard_E931.lst
Assembly listing file for the standard E931, usefull if you just want to edit an EPROM image without assembly..
standard_E932.lst
Assembly listing file for the standard E932, usefull if you just want to edit an EPROM image without assembly..
tasm6111.tab
TASM compatible opcodes for the E931/E932 ECUs. Works with the provided source files. Might be incomplete if you want to use something not already used by the standard code...

==Pretty disassembly notes==
===ECU+===
 
* http://www.ecuplus.com/forums/viewforum.php?f=4
===GENERAL NOTES===
Project started with the help of dsm-ecu Yahoo group, thanks for the great info.
Most disassembly comments in this file by Christian, [email protected].
 
===CPU===
The microcomputer chip used in the 1G DSM ECU seems to be a custom application built around the 6801 architecture, Check the 6801, 6803, 6301, 68HC11 at web sites such as alldatasheet.com, etc.
 
CPU clock frequency is assumed to be 2MHz, i.e. the instructions cycle time is 0.5us.
 
===Assembly binary verifications===
The 2 binaries produced without any customization ("enableCustom" definition is commented-out) have been verified to be identical to the E931 and E932 eprom images at hand.
 
To check the validity of symbolic substitution, the entire code section and tables
was offset by $0200 using "codeOffset" and the corresponding binary was tested on
my car (E932) without any problems for weeks. Additional tests were conducted by
writing inline code in several part of the code and no adverse effect was ever noted.
 
To check the validity of symbolic substitution for ram addresses, every ram location
starting at $0057 was offset by 1 (i.e. temp1 was at memory address $58 instead of
$57, etc) and the corresponding binary was tested on my car (E932) without any problems
during car startup and engine revving. No additional test performed.
 
This means that the code can be modified inline and in most cases, ram memories can
be moved around by changing the label addresses. Note however that some groups of
ram memories have to be moved in blocks because the code assumes they are contiguous.
e.g. the temp1 to temp9 variables, the inj1_offT, inj3_offT, inj4_offT and inj2_offT
variables, etc.
 
===Ram memory===
Memory from <code>$0040</code> to <code>$01bf</code> is backed-up by battery, meaning it is preserved when the ECU is powered-off as long as battery power is supplied. However, memory from <code>$0057</code> to <code>$0190</code> is cleared to <code>0</code> by the code every time the ECU is powered-on. That can be however changed by modifying the code... Battery backup was checked by disabling memory reset using the <code>"noRamReset"</code> and then check ram memory at <code>$018f</code> to see if it gets preserved after power off/on cycle, and it did. During the test, <code>$018f</code> was used as a distance counter using the reed switch.
 
===Comments===
Some comments use variable names quite loosly. For instance, multi-byte variables such as <code>[airCnt0:airCnt1:airCnt2]</code> might be refered to as only <code>airCnt0</code>. <code>airCnt0</code> might therefore refer to the single byte <code>airCnt0</code>, to the 16 bit value <code>[airCnt0:airCnt1]</code> or to the 24 bit complete variable, depending on the context.
 
Comments were added incrementally as my knowledge of code and variables increased. As new knowledge was learned, old comments were updated or corrected as much as possible but not necessarily all of them, so beware... In the end, the code is the only truth... Some small areas of the code were also never completly understood as a general understanding was reached and I did not care to go further e.g. airflow sensor active filter reset.


===Opcodes===
===rusEFI===
* https://rusefi.com/forum/viewtopic.php?f=2&t=622
** https://github.com/rusefi/rusefi/wiki


* <code>cmpd</code>: cmpd1 is used for some addressing modes instead of cmpd since TASM does not support unusual mitsubishi ECU cmpd opcodes.. 
===PowerFC===
* <code>brclr</code>: branch if ALL the given bits are clear
* https://www.apexi-usa.com/products/power-fc-components-universal-fc-commander-oled-type
* <code>brset</code>: branch if ANY of the given bits are set (as opposed to usual implementation of ALL bits set...)
* The addressing mode using <code>Y</code> indexing also implicitly modifies the <code>y</code> register. It seems that <code>y</code> is increased by 1 or 2 depending whether the instruction is a 8 bit or 16 bits operation... The following cases are confirmed:


<pre>
==Stims==
cmpa $00,y  -> y = y + 1  
* jimStim
cmpb $00,y  -> y = y + 1
*: https://www.diyautotune.com/product/jimstim-1-5-megasquirt-stimulator-w-wheel-simulator-assembled/
ldaa $00,y  -> y = y + 1
* Ardu-stim
suba $00,y  -> y = y + 1
*: https://github.com/speeduino/Ardu-Stim
ldx  $00,y  -> y = y + 2
std  $00,y  -> y = y + 2
</pre>


===Telemark assembler===
==Speed Density==
This assembler does not provide warning messages when code assembles to
Kim Hulkkonen
;*    the same memory space, e.g. you insert code in the middle of the file
;*    which result in the rest of the code to be offset by N bytes. This
;*    results in the interrupt vector table to be overwritten. No warning
;*    is given. The only way to know about it is to manually check the listing
;*    file produced by the assembler. Check that the buffer space between
;*    sections is all "$ff". Check that there is no code spilage over .org
;*    statements. Check that the address space does not exceed $ffff. Use the
;*    "codeOffset" at the beginnng of the file to correct the problem.


===Fuel injector and coil power transistor control===
===SwD-Swede Density===
Although the 4 fuel injectors and the 2 coil power transistors are mapped to
* http://dsmecu.com
;*   regular ports (port1, port2 and port5) which can be read to know the current
* http://kaxlon.com
;*   state of these outputs, they are also mapped in hardware to output compare
* https://github.com/KaxLon
;*   registers in order to activate or deactivate them at specific time instants.
* https://www.facebook.com/swededensity/
;*   Writing to the ports might therefore not work unless the output compare
* <s>http://www.wiki.swededensity.com/</s>
;*   configuration registers are changed to disable harware control of these
** https://web.archive.org/web/20160620033429/http://wiki.swededensity.com/index.php?title=Main_Page

;*   everything is clear to me so don't take this as gospel...:
;*    The output compare registers for the fuel injectors seem to be at least double
;*    buffered and maybe triple buffered (see schedInjSim routine). That means that
;*    up to 3 different output compare values can be written to t1_outCmpWr and t2_outCmpWr
;*    to activate or deactivate the injectors at those time instants. Each time a value
;*    is written to t1_outCmpWr or t2_outCmpWr, the corresponding injector state
;*    is also internally stored. That means that to activate injector #1 at time X,
;*    you would first reset bit 0 of t1_csr, corresponding to injector #1 and then
;*    write X to t1_outCmpWr. You could then immediately schedule the deactivation
;*    of injector #1 by setting bit 0 of t1_csr to 1 and then write the deactivation
;*    time to t1_outCmpWr. When one of the output compare register stored value matches
;*    the clock at t1t2_clk, the injector is activated/deactivated and the corresponding
;*    interrupt routine is called (if the interrupt mask is clear...) at outCompInt1 or
;*    outCompInt2.
;*
Here is my current understanding of how the coil power transistor scheduling
;*    works, not everything is clear to me so don't take this as gospel...: t3_outCmpWr
;*    is the output compare register used to activate or deactivate the coil power
;*    transistors (energize the coil and provoke ignition at the specified time instants)
;*    To energize the coil for cylinder 1 and 4 at time X you would write X to t3_outCmpWr
;*    and reset(0) bit 2 of t3_csr0. At time X, t3_csr0.2 would be loaded into port5.1
;*    which would energize the coil. t3_csr0.2 should not be changed until that happens.
;*    In the code, most of the time 2 successive values (the same one) are written to t3_outCmpWr
;*    but there are some instances where only 1 value is written. My impression is that
;*    the first value serves to activate/deactivate the coil power transistor at the
;*    specified instant while the second one only serves to generate an interrupt
;*    in order to call the outCompInt3 routine. Hence when only the coil need
;*    to be activated/deactivated without calling outCompInt3, you would only write
;*    one value. If in addition you want to have outCompInt3 called when the coil
;*    is energized/ignited, you would write two successive values (corresponding to the
;*    same time...). This is all speculation of course... As for the 2 clocks at t3_clock1
;*    and t3_clock1, I assume they are connected to the same internal clock at 250KHz
;*    but might be input capture registers latched when one of the two output compare
;*    at t3_outCmpWr is triggered??????? Again speculation, this is the part of the code
;*    I understand the least...

===Timing diagram===
* 4 cylinders = 2 rotations = 2 * 360degrees = 720 degrees
* For sequential injection, fuel injection starts on the cas falling edge
*  i.e. cylinder #1 injection starts at -5 BTDC of #3 TDC
* Simultaneous injection of all 4 injectors is performed when starting to crank or starting a cold engine or during acceleration, check the tech manual and code for more details. Simultaneous injection starts on the 5deg BTDC cas signal except in the case of acceleration where it starts when an injector is deactivated and no other injector is active (i.e. at the beginning of the time period where no injector is active)
* Coil energization is usually scheduled (the energization time is loaded into the output compare register, energization will occur at the specified time) from the cas rising edge. Coil ignition can be scheduled when energization occurs (output compare interrupt) or on the cas falling edge depending on  the desired timing. Note however that coil energization can also be scheduled when ignition occurs on the preceeding cylinder. This would correspond to scheduling ignition before the cas rising edge (at high rpm I assume). Coil energization can also be scheduled on the cas falling edge when the desired timing is high (e.g. 10deg ATDC). As this shows, there are several combinations and the complexity of the code to handle the coil reflects that fact.

where <code>maxComp</code> is a fixed offset ($64 for 1G and $40 for 2G) and t_masComp and t_masLin are table values interpolated from frequency, intake air temperature and barometric pressure. t_masComp(freq) is basically compensation for the airflow sensor charcteristic curve as a function of frequency (to linearize the number of pulse per sec vs. the volume of air passing through the sensor) while t_masLin(freq,iat,baro) is a smaller factor probably compensating for temperature drift (electronic) and airflow characteristic change as a function of air density???

injPw(usec/cylinder) = numPulsePerCasInterrupts * $9c * totMasComp * 16/256
                    = numPulsePerCasInterrupts * totMasComp * 9.75
</pre>
 
If we also assume a 14.7 air to fuel ratio, Dair=1.18 air density (g/litre) at 25degC, Dgas=0.775 fuel density (g/cc) then we would need 23900 usec of injection per litre of air using the same 260cc at 36psi, working that factor into the equation, we get
 
<pre style="white-space: pre;">
injPw(usec/cylinder) = numPulsePerCasInterrupts * totMasComp * 9.75
                    = numPulsePerCasInterrupts * totMasComp/2452 * 2452 * 9.75
                    = numPulsePerCasInterrupts * totMasComp/2452 * 23900usecOfInjection/litreOfAir
 
</pre>
 
This means that under the above assumptions, totMasComp/2452 has units of litreOfAirPerAirflowSensorPulse.
   
The factor 2452 is similar to the one provided by J. Oberholtzer, I think.
The exact value must be somewhere in that range...
   
<code>masScalar</code> is also used for maf compensation ($5e86,24198 for 1G, $7A03,31235 for 2g) for controls other than fuel injection. It probably correspond to some metric of the totMasComp curve (average or max under given conditions). From 1G and 2G numbers,
It could correspond to the max of the masComp + t_masComp(freq) curve multiplied by 0.808*128? It could also correspond to the masComp + t_masComp(freq) curve sampled at around 69Hz and multiplied by 128.
 
<pre style="white-space: pre;">
masScalar = maxTotMasComp*0.808*128 = totMasComp(69Hz)*128
</pre>
 
We then have in the case of <code>masScalar = maxTotMasComp*0.808*128</code>:
 
<pre style="white-space: pre;">
airVol16 = numPulsePerCasInterrupts * $9c * masScalar / 65536
        = numPulsePerCasInterrupts * $9c * maxTotMasComp*0.808*128 / 65536
        = numPulsePerCasInterrupts * maxTotMasComp * 0.2462
        = numPulsePerCasInterrupts * maxTotMasComp/2452 * 2452*0.2462
        = numPulsePerCasInterrupts * maxTotMasComp/2452 * 603.68
</pre>


since totMasComp/2452 is litreOfAirPerAirflowSensorPulse, we have
==ECU Stickers==
   
There are three parts of the ECU label stickers to make a point of:
        airVol16 = numPulsePerCasInterrupts * litreOfAirPerAirflowSensorPulse * 603.68
* The Mitsubishi Motors (MMC) number
   
** Starts with "MD" or "MR"
    Using again 1.18g/litre air density we get
* The Mitsubishi Electric (MEC) number
   
** Usually starts with "E2T" on ECUs
        airVol16 = numPulsePerCasInterrupts * litreOfAirPerAirflowSensorPulse *1.18 * 603.68/1.18
** Usually starts with "G1T" or "X4T" on TCUs
                  = numPulsePerCasInterrupts * gramsOfAirPerAirflowSensorPulse * 512
* The last letter of the MEC number
                  = gramsOfAirPerCasInterrupts * 512
** E = eprom
   
** T = one time programmable (otp)
    In that case, airVol16/512 can be seen has having units of gramsOfAirPerCasInterrupts
** M = masked
    (grams of air entering one cylinder). Note that the factor of 512 is not random, the
** A = ???
    factor 0.808 is used to get it in that case...
** " " (blank) = maybe eprom for 90 ecus
   
    The load index values used to interpolate the fuel map is then
   
        airVol16/2 <= 96
   
            loadIndex = (airVol16/2-32)/16
                      = (gramsOfAirPerCasInterrupts*512/2 -32)/16
                      = gramsOfAirPerCasInterrupts*16-2
   
        airVol16/2 >= 96
   
            loadIndex = gramsOfAirPerCasInterrupts * 512/2 * 0.668/16
                      = gramsOfAirPerCasInterrupts*10.69
   
    Which correspond to (gramsOfAirPerCasInterrupts for each index value)
   
            0      1      2      3      4      5      6      7      8      9      10    11
          0.125  0.1875  0.25  0.3125  0.3750  0.4678  0.5614 0.6549  0.7485  0.8421  0.9356  1.0292
   
    gramsOfAirPerRevolution would be twice those values. Notice that the max value of 1.0292
    correspond to about 250HP when BSFC=0.55 which is in the range of the stock 1G 195HP...
   
    Also notice that the 8 bit airflow airVol = airVol16/2 will saturate to $ff when
    airVol16/2 = 255 which correspond to gramsOfAirPerCasInterrupts = 1 gram. airVolT
    airVolTB and airVolB will also saturate in the same range...
   
    We can now compare these results with the stock boost gauge. It has a max range
    of 1Kg per sq cm which equals 14.2 psi. The boost gauge duty cycle is given by
   
        bGaugeODuty = t_bGauge(airVolT/32)/24
   
When maximum airVolT = 255 = iatCompFact*airVol16/2, bGaugeODuty = 20/24 = 0.83.
At 25.6 degC, iatCompFact = 1.0 and therefore airVol16=510 which translates to
1g of air. boost gauge duty of 0.83 correspond to approx. 10.9psi (by eye...).
Assuming a displacement of 0.5litre per cylinder and charge air density of  1.18
(25degC, probably too low for that psi range, unless you have a perfect intercooler..)
we would get 1.18*0.5*(10.9+14.5)/14.5 = 1.03g of air per cylinder (cas
interrupt). This is quite close to the 1.0g we had earlier.


The 0psi point on the gauge correspond to a duty cycle of about 40.5% which
==Idle Adjustment==
correspond to bGaugeODuty=9.75/24 which from t_bGauge correspond to
Maybe should be in another article?
airVolT/32=2.875 which means airVolT = 92. with iatCompFact = 1.0 @25degC,
* https://www.sixsigmatuning.com/dsm-idle-control
we get airVol16 = 2*airVolT/iatCompFact = 184 which correspond to 0.36grams of air
Assuming a displacement of 0.5litre per cylinder and charge air density of 1.18@25degC
we would get 1.18*0.5 = 0.59g of air per cylinder (cas interrupt) at 0psi. Compared to
0.36g we had earlier this is a large error but then there are several factor not taken onto
account in the calculations, I suppose???.

This is the symbolic and commented source code for the DSM E931
and E932 ECU. To assemble "standard_E932_E931_source.asm",
download the telemark assembler TASM from http://home.comcast.net/~tasm/ to the same directory and execute asm.bat from the DOS prompt.
The assembler will produce two files: standard_E932_E931_source.lst
is a line by line listing of the assembly with addresses while standard_E932_E931_source.obj is the 32KB binary image to burn
on EPROM. Default setting produces the E931 standard binary image
Required file, not provided (from http://home.comcast.net/~tasm/): TASM.EXE, Version 3.2
Contents: standard_E932_E931_source.asm
Assembly source file for the E931/E932. See notes at the beginning of that file for more details. Default setting produces the standard E931 EPROM image.
asm.bat
Batch file to assemble standard_E932_E931_source.asm
standard_E931.bin
Binary file read from an actual E931 EPROM. Assembly of standard_E932_E931_source.asm using the "E931" setting should produce an identical binary.
standard_E932.bin
Binary file read from an actual E932 EPROM. Assembly of standard_E932_E931_source.asm using the "E932" setting should produce an identical binary.
standard_E931.lst
Assembly listing file for the standard E931, usefull if you just want to edit an EPROM image without assembly..
standard_E932.lst
Assembly listing file for the standard E932, usefull if you just want to edit an EPROM image without assembly..
tasm6111.tab
TASM compatible opcodes for the E931/E932 ECUs. Works with the provided source files. Might be incomplete if you want to use something not already used by the standard code...

ECU Stickers

There are three parts of the ECU label stickers to make a point of:

  • The Mitsubishi Motors (MMC) number
    • Starts with "MD" or "MR"
  • The Mitsubishi Electric (MEC) number
    • Usually starts with "E2T" on ECUs
    • Usually starts with "G1T" or "X4T" on TCUs
  • The last letter of the MEC number
    • E = eprom
    • T = one time programmable (otp)
    • M = masked
    • A = ???
    • " " (blank) = maybe eprom for 90 ecus

Idle Adjustment

Maybe should be in another article?
