Got everything together with the LC-1 wideband output 2 hooked to the maft pro and output 1 hooked to the egrt for the mmcd. The readings are pretty close. Thanks for the help on that turbobob.

Do have an issue though. I have tried calibrating several times but to no avail. After I blip the throttle (from idle) the AFR readings are all over the place. Usually runs up to 18-20 AFR then settles back to ~14. Also the RPMS drop way low to about 400 and the car tries to die. Most of the time it recovers but sometimes not. I haven't drove it far with these settings since I don't feel I have a reliable AFR reading and the car sputters out after shifting.

I lowered my fuel pressure to about 37 psi and set my mainscale to -40. If it's just sitting I can get it to read and AFR of about 14.5. I haven't done any other low, med, high adjustments yet. Just mainscale so far.

I'm still learning tuner pro and mmcd. Not sure yet how to record and post a log. If you think that would help i'll give myself a crash course and post something up.
