scan your car and record the blms the up your ve tbales by 10% and your blms will go up roughly 7 points.

everybody was saying they arent used so i decided to find out myself and are referenced.

I come to my stated conclusion based upon my own programming experience. Yes, did your test long ago. My BLM's have always reverted back to their original numbers after adjusting VE tables. If it is something specific to yours, I would say...fascinating.

However, what reason would a MAF car use VE tables? VE tables are only assumptions that do not change and inherently cannot be as accurate as a MAF. If they did use both, there would be conflicts.

"scan your car and record the blms the up your ve tbales by 10% and your blms will go up roughly 7 points."

Hey I'll try it, Dan said it affected his freinds car also. But it's still got to be a matter of tunning preference. Dan has a point about leveling out the VE tables in the WOT range, as I see no advantage to tunning the VE table. VE cars are more sensitve to weather so there could actually be a disadvange if your not prepared to compensate.
But the whole idea of an MAF working simultaniously with the VE tables lacks any explanation of how that works.

No, but they were both OBD I computer cars with a functional maf so it shouldn't matter.
