Here's a datalog of back to back 3rd gear pulls on an 03 evo. any comments or suggestions would be appreciated. Overall, probably needs some fine tuning and smoothing. On the first pull, i get no more than 2 knock counts. knock counts get better with the 2nd pull but its because the ecu has richened things up.

my "back to back" pulls means that I go wot, brake hard and go wot again. is the richening of the 2nd pull a normal thing, or is my tune to aggressive? or something else? this is my daily driver but the tune is for the track. i'm using 91 octane with an octane booster.

thanks in advance.

Looks good to me. I wish my car would run that timing and AFR with no knock.
The second run seems a little rich, but better safe than sorry.

 

The logs do look good, but are definately rich thus the bump in timing. It may be give and take at this point with fuel/spark curves. You might try running a bit leaner and reduce the timing up top. If you can post some power graphs of the differences that would be great.

 

Yeah, I have to start using dataloglab or something.

Why do you think the ecu richens things up so much on the 2nd pull?

 

Perhaps your AIT was a bit higher on the second run triggering fuel enrichment. Did you do the second run right after the first?




Ah, just re-read your initial post...yes, this all makes sense. I'd be be willing to bet dollars for donuts that is your issue...just a little heat-soak. Are you still on the stock turbo and intercooler?


I'd still like to see you pull out some fuel and timing from the upper RPM range. The cool thing is that you're not dipping into your low octane/timing maps. You're almost there with the tune!

 

You got two timing peaks, your not knocking which is good but timing hits 5 at peak, goes up to 8 then back down to 7, then back up to 8 then back down to 7 again.

Smooth that under knock threashold, do the fuel and good to go

I guess

 

I'd lean out just a bit.
If that was a 3rd gear pull, I'd assume your 4th and 5th gear would be even richer.

I run 11.5-11.7 in 3rd gear and 4th and 5th are better...though at the higher 5th gear RPM I dip into the 10's which I don't like but can't finger out how to tune out.

 

That's because of load dependance. Me thinks you'll be fine. Nice feet, BTW...are those yours?

 

The X-GF's. They were nice. Amazing legs too.

 

You're using you X-Gf's feet as your avatar...time to cut that cord, don't ya think?

 

hows the saying go....always remember the best part of the relationship>?

 

Eh. I created the avatar when she was my gf.
We broke up about 1.5 months ago.
She does have nice feet. I'll keep the avatar. It's that or, I'll make one of my own ***. I think people would rather have her feet.

 

I'm running a white rabbit turbo with a heavy duty wastegate at 23 psi, stock intercooler. I'm surprised at how easily heat soak occurs if this is the case.

I'm a tuning noob also, so if this is normal, thats ok, I just havent seen others post about this phenomenon. When I do WOT runs 1st - 2nd - 3rd - 4th, My afr's are in the 10's by 2nd gear. Would I benefit from a more efficient intercooler? (my intercooler has 60k hard miles on it).

Why do you reccomend I pull fuel and timing in the upper rpm's if i'm not knocking? (trying to learn the thought process)

thanks!

 

10 AFR is rich.
I hate seeing my wideband dip into the 10's.

What I do is shoot for a consisten AFR and hit it. Then adjust timing until it start to knock. Then back off.

 

damn, talking about getting thread jacked!!


ummm... and please dont make an avatar of your ***.
