Admin's I am not sure of the appropriate forum for a thread of this dimension, so please feel free to move it if there is a better location for it.
I am starting this thread with the intention to simply help me document any and all information I find throughout my own Evo 8 ECU-->1G DSM process. There is a sufficient amount of information out there on the web between DSMtuners, EvolutionM, DSMtalk, club3G, the GVR4 forums, etc. But the information is amazingly spotty at best and takes a LOT of time shuffling through it all. Including the 40+ threads which most of the information lies in.
There are several different combinations and variables that affect you and your exact setup.
1G vs. 2G chassis
1G CAS vs. 2Ga cam/crank sensors vs. 2Gb cam/crank sensors
1G MAF vs. 2G MAF vs. 3G MAF vs. Evo MAF vs. GM MAF-T, vs. SD
DSM 450cc fuel injectors vs. Evo fuel injectors vs. aftermarket fuel injectors
Evo ECU vs. 3G vs. other similar ECU
Ton's of other stuff.
Over the years, I have tried contributing to our community via Eat Sleep DSM (website/social media groups/pages) and this is no different. I want to use the Evo ECU for many reasons. I used a Blackbox in my 2G and fell in love with ECUflash/EVOscan, though it does also have its downsides. I think the biggest reason why I want to use the Evo ECU is to learn more about it and hopefully clear things up. A lot of people put in a ton of effort into giving us another option for Tuning over the years. ECMlink, Jackal, Ostrich, Ceddy, Tephra, etc. Some of us take their work for granite or don't even consider it at all. I would like to promote their efforts, more importantly the efforts of those that contributed to the Evo ECU stuff.
A little background about my exact build that I am using the Evo ECU in. It's a 92 GSX, bought it as a shell back in October of 2015. Since then, I have been building it while recovering from what should have been a fatal accident in my 2G. See project log for more details. I am using an Evo 3 16G (for now until the car is up and running with all the bugs worked out, then switch to a Holset setup), RC 550's (again for now, have FIC 1600's ready to go in), 2G MAF (for now, switching to SD in the future).
I have done a wire tuck, fuse box relocation, battery relocation, deletes (AC, cruise, PS, ABS, heater core, windshield wipers, emissions, EGR, FIAV, IAC, etc.), with a built-ish 6 bolt. I have been doing way too many things at once, which is why I am sticking with a very basic setup with the small turbo, injectors, and MAF. I don't want to add to the list. One problem directly affects the rest of the setup in some way.
Now, onto the good stuff.
TYPE OF ECU:
(UNCONFIRMED INFO) I am using a 3G Eclipse ECU (2001, i4, manual trans). There are two differences between the 3G ECU and Evo ECU from what I have found up till now. The most important of the two is that pins 8 and 22 are swapped between ECU's.
(UNCONFIRMED INFO) PIN 8- Evo is for AC while it is for the Fuel Pump Relay on the 3G ECU.
(UNCONFIRMED INFO) PIN 22- Evo is for Fuel Pump Relay while it is for the AC on the 3G ECU.
(UNCONFIRMED INFO) On my 92 GSX with my patch harness, I have a wire going from pin 56 (MPI Relay) of the DSM harness to pin 8 (Fuel Pump Relay) of my 3G ECU.
On a 1G with an Evo ECU, the wire would go from pin 56 (MPI Relay) to pin 22 (Fuel Pump Relay) of the Evo ECU.
(images of pinout's will be added here once I gather them all neatly)
FIRING ORDER:
I have found that different setups may require you to change your firing order. While I have seen some say you have to use the Evo firing order (1342), this is incorrect, in my case anyway. With my 92 GSX and my 1G CAS, I'm using the regular 4123 DSM firing order. Some 2G guys with different combinations of CAS's have been known to use 3214 (the backwards DSM firing order).
ECU PINOUT'S:
1G (91-94) DSM ECU PINOUT
EVO 8 ECU PINOUT
1G--->EVO PINOUT
FLASHING/LOGGING:
You need to download ECUflash for tuning (free) and EVOscan for logging ($30)
You will need a 1.3u Tactrix cable and OBD2 connectors. You will also need to run the flash cable wire from the Tactrix cable to pin 79 of the Evo ECU. I did not make my own OBD2 port, I bought the Tactrix cable with the OBD2 port, hopefully someone else can chime in on how to make one. Seems pretty easy from everything I have read. You use a black male and female OBD2 connectors. There is a pinout for that as I believe there are multiple wires that run to the ECU wiring.
ROMS:
You have to use Tephra Mods V7. ROM's and info is found here http://www.evolutionm.net/forums/ecuflash/451836-tephramod-v7.html
Most people, and so far myself too, have had better luck with the 9653X706 ROM. Note the "X" in the ROM ID number.
If you are using a MAF (any MAF), replace the "X" with the number "0".
If you are running SD (Speed Density), replace the "X" with the number "1".
INITIAL TUNING:
If you are running a MAF, you need to edit the MAF Size values, MAF Scaling values, as well as the MAF Compensation values.
If you are running a 1G MAF, you need to enter the 1G MAF values. (currently do not have this information. most people switch to at least a 2G MAF)
If you are running a 2G MAF, you need to enter the values for the 2G MAF. (picture below)
If you are running an EVO 8 MAF, you can leave these alone for now.
I don't have any input on what you need to do with a GM-MAFT at this time.
3G MAF's are similar to the Evo MAF, if not the same.
