Evo 8 ECU In 2g Works!!

[hediki12]

tried my friends tatrix op 1.3 and still no avail so im reinstalling windows because he forgot his laptop and has to run some were... uhhhhh....

 

[tenks03spyder]

After several flashes and lots of comparing I found that the front o2 heater was turned off in perephery bits causing the front o2 to not read at all. +24 on the stft. I also replaced the sensor which required removing the turbo and manifold thanks to a siezed o2 sensor.

So I installed tephra V7 and switched all my maps over. I made sure that all the same values were copied over from my old ROM to my new one. Problem is, I can't get the car to start with V7. It just keeps cranking...almost like the immobilizer is not disabled. I put a value of 0 in for the immobilizer ('000000' or whatever it is), but the car still won't start. Is there something else that needs to be done to disable the immobilizer, or is there something else I'm missing?

Did you set the perhery bit to 0? Or just the area for the immobilizer code?

 

[the_mork]

You need to also disable it in periphery bits. If you have your bit FCA listed in hex then you want to change it to 0x56D2 if you have it listed as a blobit then you want to change it to:

0
0
0
0
1
0
0
0
1
1
0
0
1
1
1
1

Only one of those changes is necessary but I'm not sure which one because immobilizer isn't labeled but you may as well use my settings because they take care of rear02, a common idle CEL with 9653, and a couple of idle smoothing issues.

 

[hediki12]

yea i think my ecu is dead im tryin to get one of the local evo dudes to just swap just to make sure 100%. i guess it got banged up bad in the accident... so yea.

Do you mean FAA instead of FCA? The immobilizer is listed in FAA, correct?

FAA Bit 3, the fourth one up should be zero.

Perfect...that's what I did. Thanks! I'll try it out tonight.

Yep I listed the wrong bit. You can follow that definition and it will be obvious which bit to flip so don't use the setting that I showed in list form. 0x56D2 is still correct as a hex form for FCA to turn off the rear o2 and immobilizer.

Finally got a flash plug from a buddy and I just thought that I would confirm for everyone on here that you can indeed take one from any NT 2g. The 2g NT plugs have a couple of extra wires but that is AFAIK the only difference.

I can confirm this as well, i got a flash plug from a 98 gs at a junkyard.

On another note just got home from RRE about 20 minutes ago, got my IAT installed and switched over to SD Now i just gotta do some more tuning and get rid of this throttle tip in (already have a good idea of how to fix this). So far i love the fact that i can finally hear my laggy turbo spool and that i don't have that ugly maf/small filer instead a 4"X9" AEM dryflow took its place.

 

[the_mork]

Throttle tip in is easy. You simply change Asynch_vs_TPSDELTA. My right hand settings are:

13
14
16
19
22
24
27
29
34

 

[clockworktoy]

Yeah mine look pretty close to that, I added 8 to all the values and its a lot better but still goes a bit lean. Are u still using the provided ve tables or did u make you own?



On another subject whatare all ## names? I think there's just a few if us who post on here regularly and I would like to put some names to screen names.

Mork, how did you setup your VE tables? Ive been doing some reading on evom but info is scattered around making it so difficult to find clear cut answers (and im a noob at SD tuning). So far i got rid of the throttle tip in, but im still having some trouble idling and have intermittent cut off at partial throttle.

Btw my names Gus.

 

[the_mork]

My VE table is actually the same one that came with the rom. I do almost everything that I need to with the Map vs load table and the fuel table. A few people have reported that their ve tables don't look like the evo tables but I think that my evo3 intake manifold might help put me closer to them. Either way it seems to be quite happy for me but keep in mind that I can't tune idle for shit because my evo9 fuel pump overruns my regulator, when I stop being poor I'll buy one and then my VE table might change.

My name is Justin by the way.

ok got it to work the interior lamp fuse was blown. so i flashed v7 and tried logging and got these ridiculous values for the 2byte stuff.. has any one else gotten crazy numbers?

 

[clockworktoy]

Idle wasn't a big issue before the SD patch and i had it rock solid all around before. I guess i have tons of reading to do now to try to get this idle issue resolved. And geovonni i haven't gotten any crazy values before i think you might of done something wrong.

Mine runs really wacky on v7. As soon as i go into boost the car starts knocking and stuttering like crazy. I've copied every single map and setting over, and it still runs really bad.

I'm thinking it may have something to do with me running a modified version of the 96530006 xml. I went through it and commented out all of the stuff that was added, but it still runs like crap.

Anyone have any ideas?

Your mut table has been effed with (by default in v7) use 1 byte load instead.

did you copy via the tephra xml on the site? or did you just copy over your values and interpulate between them?

to the guys running six bolt with this set up... i free rev'ed to about 4.5 k and picked up knock.... now i never gotten knock in that range while driving and im wondering if the 1g/6bolt knock sensor is more sensitive than the 2g or what... i have my knock values set to what the write up has listed. thanks..

 

[GSXDNA]

What XML are you referring to? I dropped the new XML file into my ROM directory, and then just interploated all my values into the new ROM. Is there some type of translator XML?

why did i say xml.. i meant excel.. evolutionm.net - View Single Post - TephraMod V7 . maybe that will make your values smoother idk... i still haven't messed with v7 much since i had the wacky values for the 2 byte stuff... (i still dont know how to log 2byte rpm and air flow hz now i no load has to be 1 byte but havent done much reading to see the others...)

* also those symptoms remind me of when i tried to make the v5.1 map higher res. my changing the values over 100load in the ignition map and didnt adjust the ones in the fuel map. it bucked like a horse and knocked like hell.

also what are your afrs... i test drove a car the guy said it need a tune and as soon as it hit boost and the afs were 15-13 the car bucked like a dam bull n just wudnt go.... so check those if you have a wide band...

That sounds exactly what I'm experiencing. As soon as I go into boost, the car starts bucking and knocking like crazy. I don't have a wideband, but from my logs it looks like the car doesn't go into open loop. It will just stay in closed loop and keep fuel at around 14.7 AFR.

Very interesting. Has anyone been able to get V7 to work on their 2G?
