Evo 8 ECU In 2g Works!!

[knochgoon24]

I rescaled my fuel and timing maps, deleting 20, 50, and 70 load columns to make room for 280, 300, and 320, but my car didn't like that so much. It kicked an idle control CEL and ran rough. I even changed the ERG and coolant ign retard maps, but no help there either.

I'm going to try just changing the 240 load to 260 and the 260 to 300, so I have 220, 260, 300 for my last three. My settings at the 220, 240, and 260 columns were all pretty close anyways.

try 90 or 80 and then trace it in evo scan look for a cell above 100 like maybe 120 or that it doesnt "hang "around at for a while maybe has one or two rpm values thats logged at wot. also int the thread on evo scan he said try disabling the egr and coolant and stuff and that you can get rid of alot more in timing...

Well, I'm back from the track. I had a few tuning issues.
-Forgot to adjust my Boost Cut Limit. It was at 230 and that caused some problems.
-I was running rich. 10.8 AFR up top. Spool up was 11.5 AFR
-My timing was a bit conservative.

I only got 4 runs, so that didn't give me much of a chance to tune.

Ended up running a 14.787 even though I was pushing 23psi on the last run. I REALLY need to tune this better.

I also need a driver mod. My best 60' was 2.258.

Sounds like my visit to the track. Riddled with problems and only ran 14s.

Why? Power isn't really much of his problem and autos can launch just as well or better than standard transmissions. I can launch at 20psi, not that my fwd can put that power to the ground but that's life. I doubt the transmission is what slowed him down at all.


Knockgoon, 11.5 at spoolup is way slow. I noticed a huge difference going from 11.8 to 12.5 at spoolup and then another huge difference when I went from 10.2 to 11.4 under boost, it was like a different car and it solved my shift knock issues.

Yeah, it just needs a whole bunch of tuning done. My first run of the night was a 16.927 because it was running so rich that it started missing. Since nothing broke, I should be able to spend some more time tuning and get back out there in a few weeks.

 

[the_mork]

Take someone with you. I got more done in an hour and a half with my buddy Steve driving than I could have done in 3 hours on my own. Hell if you can pay attention to the log during the driving and you're only focusing on one area at a time you can sometimes skip maptracer entirely and have the new flash ready by the time you find a safe place to stop.

 

[knochgoon24]

Right now, I really want to get my MAF scaled. Then that should make getting it roughed in a whole lot easier.

 

[hediki12]

the mork, i wasnt saying that its a disadvantage i was just saying that could be his driver mod.

My driver mod is that I need to relearn how to launch. It was a piece of cake with the T25. I could just mash the brakes, mash the gas, and it wouldn't pull through. I could leave the line with 15psi.

The small 16g on the other hand, has a little more umph to it. I'm also not used to running a pro tree. Last night was my first time bracket racing.

I really need to rescale my MAF. I have my injectors set to 713 and my fuel trims are still -12% right now.

Once I get these bugs worked out, I'll be heading back. I'm not going to sit around all winter with a 14.787 posted in my profile.

 

[the_mork]

The s16g shouldn't be a huge problem. I can build boost like crazy on my e316g. I cannot just mash the gas and the brakes though. Here is what I do.

Put your left foot on the brake and press for all your worth.
Put the car in drive and blip the throttle a few times, you'll feel the brakes tighten down and the brake pedal will push in a bit farther.
Bring it up to about 3000-3500 rpm for a short period then let it come back down so the brakes really set.
Brace against the back of the seat for all you're worth and ease into the throttle until you've got the boost coming in real nice.
Launch!
?
Profit.


If you want to go faster with less transmission/brake wear look into the v7 launch maps. This will let you build more boost without building much power at the line then you'll be spooled and as soon as the car moves you'll be back to regular maps.

I FINALLY got around to scaling my MAF. Here's what I ended up with. Chances are, this WILL NOT work for most people. I have PTE 680cc injectors scaled to 609, since that's what was suggested on the Evo boards. I then turned closed loop off and proceeded to sit in a parking lot and do brake boost after brake boost. (Oh yeah. I've never really tried to brake boost the s16g before today. I can hold 22psi with the brakes, no problem. )

Like I said, this probably won't work for most people, but that's what got my AFR in check. I'm hitting just a bit above 2000hz now. By rescaling my MAF, I now hit 100 load at 0psi. Just like it should. I peak just under 260 load at 22psi, so I don't even have to worry about rescaling at this moment.

I loaded up a stock Evo 8 fuel map, with all it's super rich glory. Even running 10.0AFR up top, my car now HAULS. It got rid of that stupid stutter (along with changing the boost cut limit to 280 )

And the greatest part, my fuel maps are now almost exactly what I hit. That should make tuning a bit easier.

If anyone is still running that generic MAF scaling (the one that starts 90,90,...) I suggest spending a few hours nailing down a new scaling. I took me about 2.5 hours and 30 flashes.

Has anybody been able to eliminate the P0340 and P0335 codes? ROM id 94170008.

Thanks,

James

 

[the_mork]

Yup, its real easy. Just switch to a 96530005 or 90550001 rom.

Yep. Try using one of these two. 9653 is one of the most supported roms. 9055 is also pretty popular.

Have you changed your maf size from the first suggested 260? I need to go rescale my maf again but i get so dam lazy.

 

[the_mork]

For all the time you guys spend diddling with your MAFs why not just spend a little money (<$100) and pick up the parts to make the SD switch? Tuning is actually super easy and then you can sell your 2g MAFs to make a little bit back on the hardware that you added.

 

[knochgoon24]

I'm running the 286.0 size that was suggested.

I've been too lazy to try SD.

I plan to drop the ecu in today and I fully expect to have some issues

 

[the_mork]

I'll be around from time to time this evening so I should be able to get to any questions you have pretty quickly if no one else gets to them first. It is a pretty easy swap if you've done your research.

I actually first put in last december way when this thread was still only 2 pages long. There was a reason I pulled it out back then but I can't recall why.

A month or two back I switched to a 9653 and was getting 120 counts of knock at idle, then switched back to the 9417 that I daily drove for awhile and was still getting that knock.

With MOD coming up, it has motivated me to tune it for the drive down there.

I initially had problems getting 9653 to work right but now it works fine. You will need to change the low knock threshold.

Also, rescale your MAF once you get it running. It makes a BIG difference when you actually hit the correct cells.

 

[Hubbard 0]

Just started it like a champ, but I am getting around 90 counts of knock at idle but it idles fantastically. Before when I was gettin 120 knock at idle, the engine sounded real rough too.

Does anyone have a link for the low knock threshold on evoM? I don't have that table in my maps.

Add this to your xml for 96530006.

<!--  *** KNOCK CONTROL ***  -->

    <table name="Knock Load" address="421a">
        <table name="X" address="6576"/>
    </table>

    <table name="Knock Multiplier - Low RPM" address="177a"/>

    <table name="Knock Multiplier - Mid RPM" address="24aa"/>

    <table name="Knock Multiplier - High RPM" address="21de"/>

    <table name="Knock Adder - Single Gain" address="1780"/>

    <table name="Knock Adder - Triple Gain" address="177c"/>

My low multiplier is set at 24 right now. I know I can still read real knock, because while I was messing with the MAF scaling, there were a few times where I started running really lean and knocked.

Once you make sure that your AFR and your timing is in check, just start bumping this up. I think most people are running around 22.

EDIT: Wow, the PHP tags work pretty nicely for posting that stuff up.


EDIT2: And for those running 90550001.
