Thank you for the feed back!
I spent a little time with the VE tables last night and hope to fire up the motor and give it another go today.
I will also be connecting my lm2 wideband very soon.

Hello David......
Haven't seen you around lately. Have you been able to make any headway with the Ford?

Ken,
For the past 2 weeks my attention has been drawn to my other project.I have a lexus is300 that I'm installing turbos. Saturday morning I was able to wire the analog output from my LM2 to the ms relay board, but the outside temp was close to 100 deg so I went back in the garage and turbos. I have been reading alot on VE and spark advance tables and finally feel comfortable making changes. I did set the req_fuel back to the calcd value and increased the WUE value 60% and was able to find a steady idle, but will go back to surging after the warm up. From what you guys have suggested and what I have read I just need to spend some quality time adjusting VE table settings. Thanks again for all the help and I'm sure I will be posting a few logs and asking for opinions in the next few weeks.

Made some progress today. Increased the VE values under 1500 rpm and happy to report achieved a better idle, even after WUE completed. I was also able to measure the AFR which confirmed a lean mixture.
