my tech edge wideband should be on its way, and was wondering what a/f ratio i should be seting the microtech at. this is for a to4b turbo at 6psi (no boost controller yet) if you could give me the a/f for higher boost that would be much appreciated too.

 

bump for an answer...

 

depends what your shooting for.. 11s would be safe.. 12s would result in more power.. but shoot for 11s if you don't have a egt and want to keep things safe.

 

You should be safe with low 12's around 6psi. Taper it off into the 11's as you increase boost.

 

Dude, leave the a/f alone. The car was just dyno tuned to 11.8 a/f by a rotary specialist. Please dont blow up that car, lol.
