Thank for the help guys, got everything running correctly in my TT formula, laptop hooked up and communicating, car idles fine in Open Loop. As soon as the car warms up and closed loop begins, the idle drops, and raises, and drops, then dies. A few questions...

My 02 sensor is placed on the downpipe of one of the turbos, would this require me to have a heated o2 sensor? Is the turbo giving a cold 02 sensor bad readings?

Does the main spark table affect both closed and open loop in idle? if so, could my timing be off and still idle correctly in open loop?

Thanks again guys.

Problem solved so far. My BPC vs. EGR field was set much too low for the computer to be able to fix itself, bpc vs egr was set at .052, raised it up to .058, and it idles like a baby at 800 rpm in closed loop with 0 iac counts after warm.
