Evo 8 ECU In 2g Works!!

I just wanted to check quickly here, does anyone know if periphery bits are universal? I am not sure that I need them for my 9055 rom but if I did I just wanted to make sure that they would be compatible coming from my 9653.
 
Yes, the periphery bits are all at the same addresses for all Evo 8 ECU's.
If you add the code for the periphery bits to the "evo7base" file, you won't have to add it to any of the individual rom ID files again.

My ECU originally was on a 94170008 ROM, I experienced the cam/crank DTC and so I switched to the 9927 from the EDM Ralliart, because I can't get 9653 to work for me at all. I also noticed 9927 has a slightly more aggressive high octane fuel map when I switched. With that ROM, the only code I've thrown so far was P0090.

-Also, I'm seeing as much as 7-9 counts of knock under 45-65% throttle around 3800-4800rpm with medium/high load. I'm guessing that the more aggressive stock maps on the EDM are due to the higher quality fuel available in some european countries. I'm probably going to try 9055 next.

My front O2 sensor is also completely dead, so that and a wideband are in order before I really start playing with the fuel and timing, but does anyone know what the requirements are for the Evo ECU to begin to go into open loop?
 
I found this thread for fixing issues with 9055

P0135 CEL Fix for 90550001/98640014? - evolutionm.net

I'll see what I can get later tonight.

Also if anyone is interested there is some amount of bribery going on toward MRFred to get him to do the 9653 patch. I'm not planning on contributing because I'm moving to 9055 come hell or high water but he made a deal with somebody on evom and I was copied in the PM. If you're interested in contributing I can link you in and let you go from there. The price is quite reasonable.

Usually DTC codes are 5 digits and not 4.

i don't know what it is for the 9927 ROM you might need to do some research to see if it is the same but i don't imagine it is much different than the 9653 which is between 45 - 100% load. open ecu flash and look for open loop load and open loop throttle settings under fuel. there should be a total of 4 maybe, 2 throttle and 2 load.
 
if got a 95(95 style CAS and creank sensor) just have to swap the injector wires like this?

Pin 1(inj # 1) is now 14(inj # 2)
Pin 2(inj # 3), is now Pin 1(inj # 1)
Pin 15(inj # 4), is now Pin 2 (inj # 2)
Pin 14(inj # 2) is now Pin 15(inj # 4)

I just swapped over to 90550001 and was getting a cel for front 02 heater and fr generator circuit. I did disable the front 02 heater in the periphery and now I get no cel.

I have found this rom to run the best on my car. Second would be 9927. 9563 v 5.10 runs ok, but i get a jerk here and there during cruise at about 50-60 mph. 9563 v7.5 runs, but once i hit @3000 rpms, the car falls on its face. no one can seem to figure this one out.
 
So I just got back from having my car tuned at RRE. Scot Gray tuned my Evo Ecu for pump gas and for E85. The car runs great now and it much more streetable (still one CEL he has to help me with). Hopefully, in the next few days ill be CEL free!

I thought usually people moved injector plugs and didn't bother with the ecu wires. I've never had to do it though.


GSXDNA what rom and what CEL?

I'm running 90550001 right now too and it is working great. I disabled the front o2 heater with periphery bits also and the car started responding much better and goes into open loop just fine. It does take longer to hit open loop than some roms and it is more finicky but I've been happy enough with it an eventually plan to move to forced open loop all the time anyway someday.


For anyone else having phantom knock issues I'm working on that. I'm going to try and install some revised lifters in the near future then fill up on some 110 and see what I still have for knock. If I have anything it will prove it is phantom knock and I'll adjust the knock floor until it is gone and report back my findings.
 
i have a 95 and since i couldn´t make a 98 ecu work on my car I am thinking of getting a evo 8 ecu but i am afraid to be the same story.

has anyone been able to put the eco 8 ecu on a 95 with no problems?

An evo ecu will go into a 95 with no problems at all.

It wont help you though. The 98 ecu will work in your car unless that particular ecu is bad which is unlikely.

What is happening most likely (IMO) is that you have misunderstood or overlooked some direction that is causing you problems.

My first guess would be the way that you have wired your injectors from the post farther up. I do not have a 2ga and have never tried to swap and ecu into one but I was always under the impression that you physically went under the hood to swap the injector wires by pulling the harnesses off the injectors and moving them.



This really isn't the place for that discussion though. Do you already have a thread started on this? If not then go ahead and start one and in it list everything that you believe you should do to make the swap happen as well as everything that you have done and any problems that you have. Include pictures of anything suspect and add labels to them if you can. When you are done posting that thread then PM me or add a post to this thread with the link. If you add a post to this thread of course add a description so that it is obvious we are moving your discussion elsewhere. When you've done that I will do my best to try and help you and I am confident that with a little discussion we can make all of your problems go away. I am on here about three times a day and sometimes more.

Then when we're done with that project we can see if you still want to move to the much better evo8 ecu.
 
what is now by the way?? yea thats a big swing -- stock we are set to 7 celcius so that u only stay in open loop to warm up and then u get into closed loop quickly and save fuel

thanks monk for helping the 98 ecu works fine its in perfect working condition I´ve tried mani ways to make it work here is the thread i am asking because think many 95-96 guys would like to try an evo ecu on their cars incluiding me but since I am having problem hoking up the 2gb ecu on a 2ga maybe the evo ecu will be the same thing

here is my thread another member _Madman_ tried with the same results

thanks
 
for those of us having issues with the car wanting to die out when the ac is turned on. i originally thought it was a wiring issue. the EVO has two extra wires run to the ecu from the ac circuit. one from the radiator fan control module and one from the ac control unit. so i started digging to see what signals went to/from those wired and then made a change in the ROM first just to see. turns out the factory settings for idle on the EVO are about 850 with the ac off and about 650 with the ac on. apparently me car does not like to idle at 650 with an extra load on it. i changed it to 850 and when i turned the ac on the other i did not notice a change in the idle. i only had the ac on once for about ten seconds to see what happens but i will leave it on today on my way home to test it out fully.

also so far so good for those running 96530006 and no rear O2. three warm up/cool down cycles with a total of 6 ignition cycles and no CEL for heater circuit. i will report back today after some more driving around.

That was the first thing i checked when i noticed the ac problem. Now if only i can figure out how to fix my initial startup problem with the 9653 rom, on cold startups its kind of a rough idle for a few seconds. It always idles kind of crappy at first to the point i have to give it some gas to get it going.
