I am trying to get my 1G running correctly with the Evo ECU. Actually, it's a 3G ECU and I am using the Tephra V7 ROM (96530706). I have been searching and searching for WEEK's. All the information on the web regarding the Evo ECU in a DSM is very spotty and you have to dig through 30+ page long threads to find anything.
A little background, I bought a 1G GSX shell back in October. I have been building this thing from the ground up. Wire tuck, fuse box relocation, battery relocation, deleted a bunch of stuff (ABS, AC, PS, emissions, EGR, FIAV, IAC, heater core, cruise, etc.), painted the engine bay, complete overhaul. Car has a built 6 bolt, 1G CAS, 2G MAF (until I get this up and going, then switching the SD), RC 550's (also until I get this up and running, then putting in my FIC 1600's).
The car will fire up and run great with the stock 1G ECU. When I remove it and install the 3G ECU with patch harness, with my current ROM, or any ROM for that matter, it will run poorly. It won't idle on it's own, I have to keep my foot on the gas and keep it at 1100-1200RPM. It otherwise, sounds OK at "idle". When I try to rev it, it will sound like and IC pipe is off. Sounds like sh!t, cuts out/misfires, whatever you want to call it. See video below.
I have the correct MAF values for the 2G MAF, MAF scaling and compensation. Obviously the immobilizer is disabled. I left the injector scaling at 513 and added to the injector latencies with the correct latencies.
The engine runs the same whether or not I have a completely default Tephra V7 ROM (any of the ROM's) with immobilizer disabled. Even after the MAF and injector adjustments, it doesn't really run any different.
I have tried messing with the firing order. I tried the Evo firing order, 1342. Barely ran with this. Tried the reverse DSM firing order, 3214. Same thing. So, I know my 4123 firing order is the correct firing order. Even though I have read on multiple threads (Tuners, EvoM, club3G, DSMtalk, etc) where people said you had to run the Evo firing order. Other people said you had to use 3214 and others said you don't need to change the firing order at all. This is the kind of stuff I find when searching anything about the Evo ECU in a DSM.
I also played around with my injector plugs, switching them around to a few different combinations, no change AT ALL.
I have a wideband, but it's not connected yet. Interior is still apart, exhaust isn't installed, drivetrain isn't installed. My front o2 sensor is not wired up yet either because I still have my 2G o2 sensor in this o2 housing. So I either need to wire this 2G o2 sensor into the 1G wiring or change out the sensor with a 1G sensor. I also have an Evo knock sensor installed.
I am hoping one of you can point out something that is required to be done within ECUflash or physically with something else that I have not picked up on yet.
Anyway, thanks for reading and feel free to link any threads that may prove to be helpful.
ATTACHED IS MY ROM AND A LOG FROM EVOSCAN
