Map 0 / EBC@20psi log

just wondering why my tming is 0 at peak torque and boost tapering? I got 272i/264e cams. thx!

It is what your stock ECU wants to run... you might have a bit of knocks and that's why it is running a high det map. A ECU reset (by pulling the battery ground) will fix it, but it will eventually go back to what it is if it sees tons of knocks. The stock ECU will keep retarding timing until it is knock free.

BTW, 3250 RPM is not peak torque. Peak should be some where around 4250. I suspect that you ran some full throttle on freeway in the 2750-3000 rpm range, with will have your car running at full boost in that low rpm range. And that should be the reason why the stock ECU retard a lot of timing in those area. The ECU should try to advance a bit more if it didn't see knock in those area for a longer period of time.

You said you have EBC right? If so, boost tapers because it's the way you set your EBC. You have to do more tuning to your EBC then.

What octane and what EBC?

91 **** gas - turbosmart e-boost. I am getting rid of the ebc for a hallman in a day or 2.

Boost tapers because that's all the stock turbo can give. You have quite a bit of maf anomolies. Do you have some sort of aftermarket intake? This is why i hate the stock ecu. It runs so damn lean in the midrange. 12.5 afr during peak boost. Then the safc guys gotta add fuel which pulls timing and it's all a mess. Seems like you're on stock injectors. I've never seen static go "0" or "33.7" Usually static is "--.-" That's very odd. I've never seen that before.

i didn't even see that... could it be what it shows when the injectors are running at 100%?

I got the vividracing/agencypower intake(adaptor plate + KN cone filter). Yes, stock injectors. My car has been consistently slow, i keep getting stomped on by other evos.......

Just the filter? That's odd. I have a buschur filter, but kept the stock rubber maf pipe and i don't have any anomolies. As for getting stomped by other evos, what do they have?

Oh..and as for the ecu showing 0 timing, don't worry about that. I get negative timing sometimes. But yea, the ecu is a little beeyotch that won't show midrange timing any love.

Pretty much what I have, intake, cams, fuel pump, boost controller, 3" exhaust.
After you mentioned about the MAF, it sure looks really unstable......could it be the design of the adaptor plate causing some kind of turbulence in the flow path??

Well, i'm not sure what's causing the disturbance, but it is a disturbance indeed. This is why many utec people suggest keeping the stock airbox and putting a K&n drop in. There have been recent posts about having an air filter and that would be fine. I just don't know why your case is any different. I'm sure if you tune the utec, you'll definately pull some of your evo buddies. There's a lot to gain in the midrange and very little up top since timing is on par on the stock ecu, but it's too rich at 10.xx-9.xx afr.

I think you should start tuning as soon as you gather enough log for a base ignition map. Your car is running rich like a pig after 5750 RPM.

I'd probably just load up stage II map from turbo xs and add 30 from 10-100 loads and 2000-9000 rpms. Then start tweaking airfuel from there.

The vividracing/agencypower intake came with a filmsy aluminum L-bracket....and since the MAF signal is in hertz.....could the movement in the whole intake assembly affect the MAF signal causing the instablilty?

that would be a nice start. Get rid of the L-bracket and just let the airfilter rest on the bottom.

Abner, we need to add some fuel in the midrange. With 91, i think we should have 11.1 to 1 as soon as 19 psi hits. That might allow for more timing there as well. Your timing is deffinately flat lined. Put your stock air box on and do another log and lets see what happens.
