Anyone with WB02 on stock ecu ???
 
What are you reading for you AFRs at cruise and at full throttle?

I am seeing fluctuating between 14.2 and 15.0 at cruise and at full throttle above 4.5k it is going 13.5ish. Just curious as I am going to smog it tomorrow and its been sort of gutless, but maybe its just the 3.0" exhaust.

Looks about what I got with the LC-1 and stock ecu back in the day. After 4.5K rpm the stock goes into open loop and follows a fixed map that is set rich for safety. IIRC, sometimes I had AFRs in the 12s above 6k rpm at WOT.

Mine was the same back in the day of the voodoo box when i would take it to redline out of boost.

Same(ish) here. 14.2 - 15.5 Kinda odd that it bounces so much. I thought maybe something weird was going on. On the other cars I've had it on it was maybe 14.4 - 14.9 at cruise.
