How to add fuel with LT1 Edit?
I've been logging some runs with a 94 Camaro, and it seems to be getting quite lean!!!! It has a ported MAF and I think that may be the problem. I'm using PCMComm and I'm not too sure what values I'm suppose to be looking at for part throttle. I'm watching Left & Right O2 BLM's and they're between 130-140. Also, what is the Lfet & Right O2 Del?? They are staying right around 128..... What should my target BLM's be? and what table in LT1 Edit do I modify to get there? O2's at WOT are at 890-900mV with 0-2* KR only during shifts.
Thanks! |

If you do a search of this and on other sites, you will find most people will recommend a BLM of between 122 and 130, with 128 being perfect. As for my solution, I was running rich per my BLM readings and so I adjusted my MAF tables to reduce the amount of air actually being shown to flow through the MAF. It worked and my BLM's are now inline. start with small changes of 5% or so and go from there. Good Luck Ben |
Thanks for the info... I think its the unmetered air sneaking in through the ported MAF
