Well i have no wideband and don't have anyway to check actual AFR. MY car is basically a stock car, just bolt-ons and a converter. While reading through some of the Blogs by redhardsupra he said HERE

10. "Undo the GM marketing department's lame attempts to keep the LS1 from a F-body lower output than the Corvette. Setting the Power Enrichment table universally to 1.15 results in a much more sane (than the overprotective stock) 12.7:1 air-fuel ratio."

I also noticed that on a preliminary transmission tune FOFF helped me with he changed the stock PE to 1.2 across the board....So whats safe on a stock-bolton car without a WB??

1.15-1.18 if its mostly stock (stock untouched MAF) without using a WB 02

 

yea the car has pretty much full boltons (no pulley) and also running more timing (no Kr) so i set it to 1.15 as redhardsupra said. MAF is stock BTW

 

Mine's currently set to 1.29 across the board =/ Maybe I'll try dropping it to 1.15 and see how that goes.

 

14.7/1.29=11.39:1 commanded a/f ratio which is a pretty rich commanded...thats not to say its your actual though.

 

I think we set it to 1.29 to be "safe". It's never been tested with a WB.

 

12:5.1

 

Its extremely hard to say "safe" with no WB. The more you mod your car, the more the AFR is going to be off. I am going with Len on the 12.5.
