I'm running a little too lean for comfort on a stock fuel map and need a bit of help.
Mods: Buschur catless TBE, Walbro, and Perrin EBCS (still tweaking the WDC). I'm running the stock rom except a modified version of the jdm mivec map found here: https://www.evolutionm.net/forums/sh...d.php?t=251781. I have taken several logs, each time increasing the WDC. It's strange because in 4th gear I seem to be getting richer AFRs. BTW, at idle and cruise my AFRs are solid 14.7 +/-
Several thoughts, inside the airbox there is a honeycomb type screen (not sure if this is the maf) that I miss-aligned when putting the airbox back; I tried to set it back as best as possible and ended up bending a row of the fins. It sits almost all the way in, just a little off at the bottom toward the rear of the engine bay. The airbox to intake hose connection is a not fully seated at the bottom but enough to secure the clamp, it is seated all the way at the top. Finally, I plumbed the Perrin vent port back to the intake nipple where the oem bleeder hose was connected.
So, should I just richen up the oem fuel map per the formula on post #4 of this thread. Here are the logs, thank you for the help.
