Evo 8 ECU In 2g Works!!

[jrohner]

Also up until last night I've had the car running on wastegate pressure and I've seen a surprising amount of partial throttle knock. I've never been able to see knock before (CEL on knock) so I was just curious how normal it is, it is usually between 3 and 5 counts and I don't have a log yet because my laptop battery is poor.

Did you disable the leanspool crap so your fueling is accurate?

 

[the_mork]

My fueling is accurate with lean spool on because I'm using a stock map and evo8 injectors at the moment.

I've taken a few logs and I've been running 18psi with no knock during full pulls but the partial throttle knock is still around and usually it is at low rpms. I don't have my logging laptop handy but it seems most common right after I take off and I'm accelerating in the 3-4k range with about 30% load. I'm starting to think more and more that it is phantom knock. I'm going to dig into it a little bit more and see if adjusting the timing down in the areas that I'm having issues changes anything but I think maybe it will be worth the $80 for revised lifters just so my car doesn't sound like a sewing machine.

To me it sounds like the leanspool "feature". It leans the mixture a good 1 point. On my cousins Evo 8 on the stock map, the fueling was weird, after I disabled lean spool and leaned the maps, the AFR was almost right on where the maps were set, instead of being decent and all of a sudden going extremely rich. Yours could be going lean and then switching to about right.

 

[clockworktoy]

I am, what do you need?

I was wondering if anyone had a better formula for logging the aem wideband.

I was just curious which periphery bit this was, I looked for it on evolutionm.net but I can't find the xml for it, I'll keep looking but if it is convenient for you I'd appreciate the help.

I think some one answered this a couple posts up but if you still need it then its the FCA Bit 16.

Try dissabeling the lean spool feature and do a couple logs. Ive also had a similar problem with partial throttle knock and im suspecting its phantom knock as well, so i will be swapping out my lifters with my new ones and see what that happens.

i am using techedge, but i have noticed that the gage is a bit slower to respond then the 0 - 5v output or the logging software, so if your seeing a difference in evoscan that might be why. i did have to make a change to the formula. what is the AF range for the output your using?

you can also try turning FAA bits 9, 10, and 11 off and see if that helps. it did for me. bit 9 is cold start ignition advance. 11 is egr ignition advance. and they aren't sure what 10 is for but several people have confirmed that it does add ignition advance. it reduced light to mid throttle pulls for me considerably. it also helped with my idle. it use to waver a bit and would change slightly from stoplight to stoplight now it is rock solid at 900rpm and i dont show nearly as much knock.

 

[the_mork]

Ok a couple of quick questions then. I've disabled FAA bits 9 and 10 but 11 was already disabled and the label is different specifically where it says (set bit=1) at this time I'm assuming that I should leave it set as 0 but I just wanted to double check.

Also my option for disabling lean spool disappeared after I added the full periphery bits xml but I did find a lean spool under FBA bit 7 which was already set to 0. I just wanted to double check that this was correct, I'm assuming that it is and I'll go out and flash my car now then head to work and report if it takes care of my part throttle knock.

I do refresh the ecuflash forum and evolutionm every day and read anything that is new but it takes me a bit to find the information I need, probably just because I haven't been paying attention for long enough.

Edit: The periphery bit for clockworktoy and delta448 posted are different FAA 16 and FAA 8. I'm assuming that there is just a naming difference here because I don't even have a bit 16, I have 0-15 and using the changes that Delta448 posted bit 8 appears to deal with the right section (though it only lists turning off p0506 and p0507). I'm not really asking a question here just noting the difference in case someone else has the same problem and looks through here.

here try this i just found it while looking for something else. it seems to be the most accurate listing from what i can tell. also from what i can tell you do change FAA bit 11 from 0 to 1 to disable egr.

Ok, this has helped clean up some of the knock I was experiencing but not all of it. I believe that I am experiencing phantom knock between 2800rpm and 3000rpm at just about any and all load levels. Just about any other rpm range seems perfectly happy. I was quite bothered by my drive home when I was cruising along the highway with my foot barely on the gas and seeing more than 5 counts of knock (knock on cel no log) at the 60mph that I wanted to be at (2900rpm).

My p0505 hasn't come back but I only drove to work and back.

It would be hard for me to believe there could be real knock when not even boosting, but have you tried to pull a couple degrees globally from the whole map just for the fun of it to see if it makes a difference?

 

[the_mork]

No I haven't yet. I've been coming home beat this week so I haven't played with it much but I thought that I might go ahead and fix the egr bit that I had wrong with this last rom then try it again. Afterward I will go back to my original plan of pulling 1 degree of timing globally since that appears to be where the car wants timing to be anyways (consistent 3-5 knock count). It could potentially want two but I think that is overkill for a global adjustment without more logging.

 

[mike96]

Turning off FAA 9 and 10 helped me out as well but i still get just a little bit of knock every now and then. that flash on knock is kind of nice to have but a burden at the same time, if you smell what I'm step'en in.... i might try the same when i flash my car again this weekend to get rid of the rear O2 CEL with the heater circuit patch from Mrfred... i am just waiting to see if i truly got this P0125 solved.....

Thanks to everyone for all the input so far, this thread is turning into the definitive guide for swapping the EVO 8 ECU into the 2G DSMs.

The_Mork has already summed up the information for finding and modding the correct ROM so i will not go over that.

I would like to update the physical part of the swap and confirm the information here is correct from people who have the swap working correctly.

You must be logged in to view this image or video.

Swap pins 8 and 22
Connect pin 32 from the EVO ECU to pin 20 on the vehicle wiring for the eclipse
Connect pin 34 from the EVO ECU to pin 21 on the vehicle wiring for the eclipse
Disconnect pin 87
Disconnect pin 42
Pin 40 should be left alone.
Pin 92 is confirmed to leave in place.
Pin 82 is called 'ignition' but has no dual in the DSM ECU. Leave this alone.
Removing pin 58 stops the tach issue described on the first few pages.
A/C and Normal cooling fans should/do work fine.

=================

Also, this is a link to my XML file i have setup for ECUFlash.

XML for V5.10 ROM 9653

ROM image to accompany the above XML

If anyone wants to use this you must of course change the Injector settings and MAF scaling if your not using the stock EVO MAF. Right now it is setup for PTE 680 cc Injectors with stock EVO 8/9 MAF. To find the Injector settings that should get you started check this Image:

The AF range is 10-19.98. I guess there is a time difference between the gauge and what i log but under WOT the information seems to match. Im still looking into the formula im using, so hopefully i can resolve my problem soon.

so your formula in evoecan should be either .03913*x + 10 or .03914*x + 10 .... does it look like there a bit of a miss match between your display and evoscan?

Whats up with the sensor ground on pin 40? has anyone touched that or did you just leave it as is. Everything appears to work correctly?

on the EVO8 the cam,crank, and one other sensor are grounded here. i tried moving the grounds to that pin to see if it would get rid of the CEL for crank and cam sensor when using a 9417 ROM but the signal is actually different. so nothing needs to be hooked up here.

Has anyone touched pin 92? Is it ground for both the DSM and EVO ECU ?

yes and no, see above post. you can leave all the sensor grounds here at 92.

Pin 82 is called 'ignition' but has no dual in the DSM ECU? true?

i don't believe i have anything hooked up here

Removing pin 58 stops the tach issue described on the first few pages. Does your tach work at all with this wire disconnected?

yes tach works fine. on the DSM the ecu gets feed back from the power transducer to make sure the car is running. the EVO doesn't care it just assumes.

Have the issues with the AC/normal cooling fans been resolved? Swapping the pins from Post 1 has corrected this issue? The fans behave normally with the above pins swapped? Or do the fans run all the time (with ignition).

as far as i can tell the fans behave normally. i haven't seen anything to suggest otherwise.

 

[mike96]

also, try these XML's. i have put together a couple of comprehensive XML's that i use. the only thing that is a little off in my XML's is that there is an extra turbo section. the section for direct boost control has all of the files that you need to control boost directly in it. to change the load based boost you need to modify some of the files in "turbo boost single solenoid" "turbo" and boost error correction under direct boost control. i know this is true for the 9653 but i haven't used the 9055 in a while. i was going to use it to switch over to speed density, but with JcBanks saying that he is almost complete with SD for the 9653 ROM i am holding out for that..... just change the ".doc" to ".xml" and use the included evo7base just to be sure everything works.

 

[ZLODEY]

The color-coated pins indicate those that need to be swapped/changed/disconnected:

Swap pins 8 and 22
Connect pin 32 from the EVO ECU to pin 20 on the vehicle wiring for the eclipse
Connect pin 34 from the EVO ECU to pin 21 on the vehicle wiring for the eclipse
Disconnect pin 87
Disconnect pin 42

I got it right that when we connect pin21 (A/C Fan LO) > pin34 on EVO ECU we have pin21 (Cooling Fan Relay) disconnected at all?

 

[the_mork]

yes tach works fine. on the DSM the ecu gets feed back from the power transducer to make sure the car is running. the EVO doesn't care it just assumes.

This was one of my biggest annoyances, I somehow missed it earlier and I'll try it today. I also wanted to report that disabling the EGR ignition advance did terrible things to my idle. For the record at the time I had a fully functioning EGR system so I might try it when I have my car fully back together without an EGR system to see how it goes.

 

[clockworktoy]

so your formula in evoecan should be either .03913*x + 10 or .03914*x + 10 .... does it look like there a bit of a miss match between your display and evoscan?

Yeah im using the 0.03914*x + 10.0 formula but the problem i see is that there seems to be a 0.5X difference between the gauge and the log. But ill keep looking into this a bit more since im sure the formula needs some adjustment. On a sidenote i need bigger injectors!

i havent tried disabling my EGR yet i might do it today just to see if i have a problem.

i never really paied that much attention to my gauge to notice a differance in the two i usally just use it to make sure that i dont go overly lean...... and i to feel your pain as i need larger injectors as well. i thing some 1050cc would do nicely

 

[the_mork]

Just to clarify I was talking about EGR ignition advance only, not anything else related to EGR.

 

[Silver2GST]

Thanks Mike96! For clearing those things up. I will update the image ASAP! Once i get the tune solid i can not wait to try out the ECU Boost Control and gear dependent boost control that is in the works for Tephra Mods V6.0. That is gonna help my FWD traction big time! You gotta love all the homebrew support the EVO ECU gets. I now live in the ECUFlash section over at EvoM just reading all the time!

Im on evom at home and school, basically 24/7!

Im still running evo 560's! But i think my maf scaling could use some work, either that OR my injectors are just dying at 19psi (go above 90% IDC's).

i think we are all on evom as mush as we are here.

evo 560's running out of room about 19psi, that makes two of us..... i think i want to pick up a stock injector or two and see about doing the Subaru injector mod to one of them and see what it does.

Yeah, but i think i just solved my injector dilemma. AEM meth injection here i come!
