Homebrew stage 3 testing (Part 2)......

PSmalls::DoggieStyle · 07-23-2005, 01:33 PM

For those interested in seeing the first post on testing my stage 3, click here.

I apologize in advance for using VAG-Com to do this round of logging. Poppa Midge took the ECUx laptop for the weekend so this is the best I could do.

The temperature was 91F, I had half a tank of Sunoco 94 octane gas, and I live at ~900 ft above sea level.

The only changes in Lemmiwinks since my last post are a 10% reduction in channel 3 and a ~2.5% reduction in channel 10.

Note: My boost is spiking to ~21.5 psi and tapering to ~20 at redline...haven't touched the boost controller since last time....

Block 003 (MAF and timing):

Block 031 (02 voltages):

After looking at this log, I reduced channel 2 and channel 8 by 10% to try and eliminate the initial 02 voltage spike and the high 02 voltages at high RPM WOT, respectively. I'll be sure to do more logging soon to see if these changes did indeed "solve" these issues.

Overall, I am absolutely 110% satisfied. I can't stress enough how great the car feels. It is like I chipped all over again. I can't wait to see how fast it is in some decent weather.

4 flat is a good place to be in this weather. I don't think you have to tweak much more

I'm having some misfire codes at idle with the bigger injectors. I don't feel them at all and they don't trigger a CEL, but I can watch them via VAG and see the codes pop up every couple days. I just keep clearing them, not big enough of an issue to do anything about it yet IMO.

I can't remeber off the top of my head, but I think I averaged more RPM's per/sec than you but had a slightly slower FATS time on one of my race programs. I want to know why that is. I am thinking my K04's seriously crap out in the top end.....
Good work man.

I'm having some misfire codes at idle with the bigger injectors. I don't feel them at all and they don't trigger a CEL, but I can watch them via VAG and see the codes pop up every couple days.
