What's the most beneficial A/F ratio?

so you guys have never thought about megasquirt? For about $180 you can control fuel and spark completely. diyautotune.com has prices and for info go to megasquirt.info For your VQ's Id use Megasquirt 1 and Megasquirt N spark-extra software. Thats what Im using in my RWD project and Im using it on a VQ30. It'll work fine with the stock coil over plug setup too.

Yea I cant wait to start either!! The weather needs to make up its mind though, 20-30 one day then 40-50 the next. Oh well Im going to order the MS soon and put it on my VG to see how to set it up and tune it. I cant wait till spring so I can start working on the body.
Allen- Hows the IM going?

The answer is go tune your own car and find out... everyone's car and mods are different not to mention atmospheric conditions and dynos but generally it seems it's in the range of high 12's to mid 13's.

Just like every car has a different base A/F before tuning, every car is different and will react so to various A/F's.
Just like 1/4 mile times and dynos, it depends on the conditions on the day of tuning, etc:
On a side note, I've heard that keeping a constant line (straight) is best for VQ35's. Other's tune a bit more rich up top. One logic for this is to reduce/reguate heat up top, as well as companesate for spark energry reducing as engine speeds increase. May or may not be true.
Another one of those situations where there are too many variables to decide what is the best A/F for a given car for a given day.
Back to the cookie cutter method...
