ok i have the wideband and boost controller hooked up! woohoo. thanks judge ito. still need some other stuff fixed tomorrow but i drove it home.... OMG i need to tune this thing so bad AFR is all over the place. when on boost its at 10.00 SUPER RICH..... right now i'm tuning the vacuum maps. anyway in vacuum it seems to be happiest around 12.00 AFR... in boost i want to get around 11.5-11.8 AFR. sound good ?

Aim for 11.3 to 11.5 @ WOT & boost above 10psi, just to be safe ....
Just creep up on it Vosko, don't do radical changes and you will be right.

i have been messing with vacuum maps and so far its working pretty good!... i spent an hour. cruising is MUCH better. GOD I LOVE MY WIDEBAND!!! i dunno why i bothered tuning the car without it!!!!

cool. when i was playing with mine, i didnt really look at the wideband for the vacuum i just made it run the best. the wideband is a graph, 10 feet away on the dyno, so for wot i just made sure that the afr didnt move when the boost comes up. then we made some runs, and i tuned from there, mine was so rich at first when it hit boost it would foul the spark plugs
