Need AFR help with LC-1 and BEGI FMU
I am going to the dragstrip in a few hours with a bunch of other faster cars that I still need to try and beat. I have been running so rich lately that I pop when I shift, so I backed out the adjuster on the FMU a few times and did logs. I really want you guys to look at my afrs but how do I post the .log files?

popping when you shift is because you are running an AFM and a BOV that dumps to atmo. It's because you dump out a lot of metered air so you're a bit rich while decelerating.
It doesn't mean that you're running too rich while in boost. Take a screenshot of the run, save it as a png or bmp and upload it to a hosting site like imageshack. then use the insert image button on here. |

zoom in and show just one run per image
you may need to upload multiple images |

keep the laptop ready to record...get in third gear...hit 2500rpms...hit record...floor it...stop recording.
|
yeah those aren't full gear pulls. but it looks like you're 11.75:1 going to 12.0:1.
I'd like to see a whole pull... |

Wish me luck tonight anyways. Although I am more excited about the ferrari 360 race! I won't be redlining in third, anyways, cause its just the eighth. |

Drag racing went well. Raced a friend of a friend who said his 97 eclipse could run 8s, it can't. Also smoked a magnum truck and a beefed up montecarlo. Even though my eighth was only 9.8, it was pretty fast for the track/weather. The only cars faster were the seriously modded awds and v8s with slicks. 10psi will be ready for the next one, hopefully. I am curious to see the absolute max limit of the stock clutch. I'll turn the boost back down until I buy the ACT. Thanks for looking at my AFRs, heres the 3rd gear run today...

Am I about right or should I tweak this at all?
|
Lean it out abit past 6K rpm and you should pick up a little power try for 12.4-1 past there.
|
Thanks man! I will shoot for that when we go 10psi, also.
|
there is no way to lean it out after a certain rpm. the ecu goes nuts at 5500 rpm, and injector duty cycle shoots towards 90%. it's going to be rich up top. you'll still make power. when/if you go standalone, you can get your flat a/f curve.
