Thanks Boz
With the warm start after the car has been running it is very likley that your AIT sensor has become heat soaked. This is very common on Speed Density. Now it will not affect you unless you have your AIT Correction table dialed in. So when you fire yoru car, it thinks the AIT is 140* when it is really only 85*, and your car will be running an AIT Correction of -xx% based on your AIT Correction table. A way that I have worked around that is with the Start Extra vs Temp table. Up in the 122+* range be sure to add fuel so that your AFR will be in the 13's, this way the 10-15s it takes for your AIT sensor to get to the real AIT you will just run a little rich, but at least your car will start and say running.
