Evo 8 ECU In 2g Works!!

[tom04841]

I'm running fine on 9927. 9563 idles for me, but as soon as i get into boost, it feels like i hit a wall and she breaks up pretty bad. I don't know what the hell is going on with that.

i had a similar problem, does your car seem to stutter a little bit at an even cruse speed? if so try switching your fuel injectors 1 and 2 .... 3 and 4. that fixed it for me...


i have ran 3 roms...

currently running 9653 with the hopes that i wont run into any issues when i emissions the car next month. car runs great with the only cels being for rear O2 (it is completely removed right now because i am trying to get mfreds patch to work.) and the pesky cels for idle circuit and generator FR circuit, which i believe to be linked and have a theory on...maby the alternator isn't putting out the correct voltage because the pulley ratio is off. the evo is a serpentine belt after all. i to am waiting for JCBanks SD patch for this, especially if it passes emissions with no problems.

i have ran 9055 before with no issues other than the occasional cels for (again) idle circuit and generator FR circuit... go figure. only problem with this is as far as i can tell there is no emissions tests in this ROM so i don't think it will pass Nevada emissions.

and i have tried the 9417 Roms. the car seemed to run well with this ROM but....... i couldn't get around the CEL for Cam/Crank angle sensor malfunction. i have a 96 eclipse so both the cam and crank are on the same side of the engine. the evo is more like the later eclipses where the cam sensor is on the opposite side of the engine from the crank sensor. i am pretty sure that is half of the problem. the other half of the problem is the trigger wheel, i found a picture of what the evo cam sensor looks like inside and the wheel is quite a bit different then the eclipse cam sensor. other than that it worked fine, car ran grate. and i would love to switch to that ROM with the support of the evo community and all the patches.....

I find it very interesting that I have had none of those problems. Maybe the 2gb is more compatible because of the cas positioning. The only problem that I've had was an intermittent idle control system malfunction which I fixed with the periphery bits.

With the 9417 did your CELs come on right away or did they come on over time? I'm curious because I think I would like to start working on playing with this rom. My only reason not to go with 9055 is the lack of ecu based direct boost control which I would like to have at some point.

In CA, when you hook up the OBD II at the smog shop/dealership/wherever, it displays quite a bit of information to the techs. Including what car the ECU thinks it is in. A car that thinks it is something else will not pass. Do you think it is possible to "rename" the ecu?

North Carolina emissions are the same way. I know of a couple guys who were having problems with emissions running DSMLink in a 2Gb due to the ECU.

no the CEL's came on as soon as the engine cranked every time after a flash, or i cleared the CEL's.

what bits did you use to clear the idle codes, i think i checked the bits you mentioned in an earlier post and mine were set to 0 but i was still getting the DTC for idle.

i can't seem to find anyone here who can answer that question for me, so i don't know if it will cause a problem when i go to emissions next month and they plug in my car and it tells them it is an EVO not an eclipse. as far as changing the VIN or car info i don't know if we can, as far as i know only the dealership can change the VIN.

Have you tried just getting the blobits xml and then running through the lists to see if there is a bit that disables them? Mine was easy but I believe that your issues are somewhat different, a link to the xml is a couple of pages back or it is on evom.

I don't think anything is sacred on these ecus anymore, try ecuunlocker from aktivematrix.com (< I think that is it but I didn't check). If that doesn't work try posting a request for help on the evom ecuflash forum. Those guys seem interested enough in this project to consider helping.

i have a just about every option plugged into ecuflash right now including all the SD stuff i think my 9653 xml is over 25 Kb and my evo7 xml is over 44 Kb.

i'll give ecuunlocker a look and see what i can do with it. if not then i have my car setup right now so i can put the stock ECU back in easly. takes about 5 min. if it dosent pass with the evo ecu then i will put the stock ecu in and look into fixing the evo so it will pass a little later.

 

[the_mork]

I lied, 9417 does throw codes but I didn't check what they were I just changed back so I could go to work. I also didn't see a MUT table listed even though I had pretty much the same xml as with my 9653, does anyone have a good link for understanding the MUT table?

 

[johnnyboy55]

haha no to the guy with the smog question -- ## ecu throws an id which is a number not the actual model of a car -- so the guy says u have id whatever which points to an evo in the system and that cannot be manipulated as of yet -- ## throwing an evo id

someone was saying somthing about a fuel pump dual voltage -- u run low voltage at idle and then higher voltage at high load to allow for more lph up top.. The fuel pressure solenoid helps with overrunning the fpr so its pretty hard to do so with the stock evo setup.. FPR, solenoid and dual voltage setup.. i believe the ecu sends the trigger to activate the 2nd voltage when it needs it.. otherwise its in low load mode.


also when u hit boost limit u feel the brick wall someone mentioned.. So check the boost limit function on the rom and set it to higher and try again.. Also make sure ## scaling is good and the maf size and scaling is good or it will give u a wrong load and ull hit boost limit faster.. IT is done by load so around 12 psi is close to 180+ load and 18 is close to 220-240 ull have to figure it out on ## car..

when you say "understanding the MUT table", do you mean what each value means or just what you need to view it. if it is the later than when i get off work i can post mine up. someone sent me a copy of their XML from EvoM, i thought i already posted it up here if not i will when i get home.

i was kind of figuring that with emissions.

for the dual voltage i don’t see where it's a problem, my understanding is that the evo has a fuel pressure solenoid that performs the same function as the FPS as the eclipse. helps with hot restarting. all the EVO ECU does is close a relay to bypass the fuel pump resistor and allow full voltage to the pump.

 

[johnnyboy55]

## right dual voltage is no problem -- i just saw a post on it but yea on the norm everyone will run with the defualt full voltage or high load just as normal.. maybe im reading it wrong - but the ecu triggers the low load i believe meaning it will use the resistor to make lower voltage for idle and such and then bypass it for high load or turn off the trigger with the ecu.. is that what u mean? I dunno if someone is trying to run this type of setup or not? People are running the 255lph with stock setup no adjustable fpr...

both kind of...I don't need to understand each address, I understand that they are memory addresses for handling logging output, but I don't know how to read a MUT table to find out what address is at a given area. I understand that it is Cartesian but when you throw in hex values and rescaling I get quite confused.

I'd also like the line that shows the MUT table, I was very surprised to not see it considering I was using a Tephra patched rom (5.10).

I didn't play with roms any more today because I was rewiring my wideband so that I could listen to AM radio while it was plugged in (power/ground were wired to the radio) and going over some old connections that I did hurriedly and therefore weren't soldered.

I'll try going back to getting some different roms to work tomorrow or Thursday.

I have a quick question for anyone with a GM map sensor. I just purchased one but I was a little bit curious how they mounted. I have an evo3 intake manifold so I don't have a place for a stock mdp and I was wondering if I needed a bung or some other hardware to mount it. I actually think that there are people using it through a vacuum line of the FPR for SD but I wanted an opinion on what was the best way to set this up. I don't mind drilling into my manifold but if it weren't necessary then that would be nice. The biggest question though is what sort of bung I might need. I'll be ordering one for my MAT sensor and I'd like to get them at the same time to save on shipping and headaches.

Also both the TB elbow and the intake manifold are aluminum right?

OK so i tried to post a reply earlier but had a problem and now i am glad because i had a chance to look over the FSM and i was only slightly wrong... there is a resistor in line to the fuel pump to reduce the voltage to the pump during idle and light loads. i thought that under heavy loads and WOT the ECU switches the resistor out of the picture so that the pump is at full voltage. i thought the ECU closed a relay to bypass the relay but actually the ECU holds the relay open until the ECU needs the extra fuel and then lets the relay close. i think they did it this way in case there was a problem with the relay it would fault in bypassed so you wont go lean under boost.

i think the subject came up because GSX was having trouble getting some fuel injectors dialed in. i can see where this might be an option if you are running larger injectors. it would let a set of larger injectors run like smaller injectors under lite loads. for most of us not using this setup i think we can use it for something else... like ECU based NOS or meth control.

 

[jrohner]

That's what you need to do if you have a 95-96.

 

[mike96]

try this for mut table. if you don't want all the filler FFFF's let me know i have another mut table definition without them. exactly how people come up with what the values are i have no idea but figuring out which values people are changing is pretty easy just start with the vertical for the first part I.E. MUT1x, then follow it to the right until you get to the last digit, there you are...

edit........ that didnt show the way i wanted it to.... so here is the .dat version, just change the extension to txt.

 

[mike96]

i know it is WAY O.T. and a little old, but i was trying to find something for another member regarding the cam sensor for the evo and found this....

Beer can stuck way up in the exhaust pipe - ?? - evolutionm.net

post 11 is my favorite.....

!

and i checked today and the 9417 rom gave me i think cam sensor malfunction or something. I should really write these things down.

 

[mike96]

i know someone here said they wanted to be able to run the 9417 ROM because of all the supporting mods (SD, tephra, boost, ect.) i have been talking with a newer member and we may have come up with a possible solution to the CAM/CRANK DTC. give us a little time and we will see where this leads us.

 

[the_mork]

That would be great!

I don't have any emissions here so I might just run the 9055, the only thing that I don't like is that it doesn't have ecu based direct boost control available for it but I haven't even bought a GM bcs yet so I guess I can live without it.

Sweet, i hope you guys figure something out. I would love to run SD

I'm trying to hook up my GM map and the wire colors on the Eclipse MDP are different than the wiring on the evo MDP. Does anyone know what is signal, what is 5v reference, and what is ground (I assume the ground is the balck wire).

Is there a simple way to test this? Does the 5volt reference put out 5volt with key on?

The 5volt reference does indeed put out a constant 5volts w/ the key on. Use a multimeter to check continuity between the 2 remaining pins to ground.

 

[the_mork]

I used my multimeter but none of the wires appeared to offer 5volt. I'm at a bit of a loss. I might just try pairing different wires until it works.

Edit:

I found some information:

Here are the connections:

MAP Function MDP

A Ground Black

B Signal Light Green-Black stripe

C +5 Volts Green-Yellow stripe

GM 3 bar map sensor install for use with DSMLINK VFAQ

 

[mike96]

according to eclipse FSM

black = ground
green\yellow = 5v
lite green\black = signal
