Update with issues...

As you know I finally got the car to turn on and stay on. The car is idling smoothly (no oscillation) at a high RPM (1200-1500) and the AFR reads super lean. Well, off the charts apparently. The AFR on tunerstudio reads ~19.5:1 and my UEGO guage reads nothing (out of rang I assume). Additionally, when I go to VE Analyze Live it reads "O2 Out of Range".

I did some research and found a couple threads on MS Extra that mostly pointed to wiring issues. The AEM wideband currently has the single signal wire going to the MS unit and the ground wire going directly back to the MS Unit. I also hooked up a voltmeter when the car was running and it read roughly 5.8 volts... (which is about 20:1...about what Tunerstudio says).

Here is a log of the car at idle.

I forgot to take the MSQ file off my laptop so I will post that later if you guys need it.

Also, I set up the EGO control to be a single wideband, and I calibrated the VE table based off the AEM UEGO settings.

Do you guys think this is a hardware or software issue?? I tried richening the tune and the AFR never changed...
