Also what you put in the cell is not necessarily what is going to show up in the log file. In other words you may have to put 12.7 in your AFR at idle to get 13.2 or whatever.
Also the Heat Based RPM table can be your friend.
Seems odd. Is the heat baking the TB and screwing with the TPS Sensor? You free air calibrated? Did not run any Octane booster? TPS and IAC were right? Have you gotten into the habit of working the throttle grip before each start to ensure butterfly/TPS is 0 set?
What type of motor work?
I have forged pistons so even in the summer they need a good while to get warm and expand. I have always warmed forged pistons longer then cast as I was taught that way. Anyway point is the TCFI NEEDS to warm up, if you fire it up, and ride off you are in for some evil for awhile. It takes like 180 sec to go warm off the O2's. Not a biggie to me as I have to wait anyway.
STB glad to hear you are squared away now. That is why we need to talk and share this stuff.
Sorry to all else, but there is nothing controlling EFI like a IID. Anything else is just a mindfuc for the ECU.
I did not always feel this way and still am not in love with Customer Support, but others are getting some good information and building a rapport with Chris.

The issue was not nearly as "known" in Texas as it probably was in PA, so I had it for quite a while until I found this board and gave it a shot with a post. Chris forgot to mention the known quirk which quirked my bike for a few quirky months. All is well now. Shortened warm up time and warm up temps for O2 control works well in this hot part of Texas.
