K, I started with the stock azty.bin (1991 3.1L) and made the following changes. Does that look okay?

I turned up the closed loop min temp to 153*. I'm now working on getting the open loop AFR down. Right now the o2 says its running .200V lean. Still smells way rich. Idle is 600RPM and 60kPA, open loop.

Things I will modify

Main Volumetric Efficiency Vs RPM Vs MAP
Closed Throttle Open Loop AFR Vs Coolant Temp
Idle Volumetric Efficiency Vs RPM Vs MAP
Open Loop AFR Vs Coolant Temp Vs MAP

Watch the lean cruise stuff. Sometimes it can make you WAY to lean. In some masks there is a highway spark mode. Which can add too much timing.

I found both these out when I first enabled mine back in the day. It would run the motor so lean the o2 SES light would come on under cruise.

Could someone with a cam that idles at 45-60kPA please show/send me a copy of the VE tables for idle. I'm having a very hard time getting this system to idle right.

It idles okay at 55-60kPA at .220V on the o2, but any amount of throttle, even the TINIEST crack, and it jumps up to 2000rpm. Stock program or modified, I just can't get it to be better. Thanks.
