My TEC3 can run in either closed or open, as you know. I tune the VE table without the O2 connected to the system, however I use the O2 sensor (stand alone system) to tune the AFR. Make sense? Once the numbers are close, then I use the O2 in a closed loop to fine tune the numbers. It's quite possible that the O2 connection within the TEC3 was sending info to lean out the AFR under demand conditions.

I got the TEC3 back yesterday and put it in the car. There is a big difference right from the start. The idle is stable - almost rock solid. Cruise is very stable, but off accel is dicey - I think I can tune that better. Cold start worked good this morning. So, my update is, so far, so good.
