Yea , we found 1 part in the pcm were if you were making over 350 torque in first gear it pulled timing. Sucks when your putting down 400+
How does it measure and feedback torque ?? .....other than being able to detect wheelspin.... :?:

I'm curious myself.

sweet, looks like it was a great day... you must be spinning A LOT because those are sub par 60'* for a warm day... any idea on what the air temp, track temp and humidity was(definitely plays a major role)? did you ice it down between runs??
The air temps were low 70'*, not sure on track temps or humidty. I didn't do any ice or anything, car sat in the lanes with hood open till I was up, roughly 30min a run. Didn't do any real track prep, had couple of gallons of 100 octane, and low fuel light was on Didn't change tire pressure or anything, raced it just how I brought it in.

Not sure what all sensors it uses, but one of the parameters autotap can read is delivered engine torque. How it derives this I don't know.

Why don't you try to do an autotap run with your wheel speed sensors disconnected and tell us if the engine torque still displays a value. This should tell us something.

I could but my torque mgmt stuff is disabled so not sure it would give any data anyway.

I think I'll try a few seat of the pants runs with them disconnected just to see if it makes any difference.
A torque sensing device would be very expensive and I cannot find one anywhere in the transmission schematics. I'm almost convinced that it is an algorithm programmed using the vehicle wheel speed sensors and other engine parameters. Not unlike the tire air pressure algorithm GM uses.

Taylor should have his Intense PCM soon. If it works well for him, I will follow.
Did you notice that the ZZP shirt had an INTENSE decal on it too.
