[QUOTE="mandkole, post: 1181873, member: 4630"] Its beginning to seem like its in the switch or the chip. First attempt to cold start was a hard romp. Shut it off. Rekeyed and another romp. Off.. Played with the switch and keyed a clean start (cold haze). At this point, I noticed that I could move the switch through all 6 positions and it did nothing--even the whisper tune and no start didn't work. 14V at the battery at idle. (While it was idling, I pulled the ICP plug for grins and it went to default with CEL. Put plug back in ,restarted, the CEL turned off and it went back up to 875 where Bill set it.) After idling it to 110F oil temp, I felt confident enough in it so I took it out and drove it for a little while. Nothing unusual. After 165F oil temp, I got on it a little (in what was supposed to be the max effort tune) and saw only minor levels of smoke at low boost tip in. It actually felt like the tow tune. This seemed to make sense since I saw ICP at 32-3300 which is not likely for the race tune (closer to 2900-3K). I forgot to check PW... crap. Got back home and it idled clean with no smoke. While idling it after the drive, the whisper and no start worked again. Anyone have other ideas or thoughts? I may try a new 6 pos switch. [/QUOTE]
