Probably best to just insulate the sensor. The extra cooling you get on the front of the pan in warm weather is probably helpful.

Fred, please allow me asking some questions in regard to the FAST traction control if you don´t mind:

What are your experiences with the FAST traction control so far?

Does it work smooth and efficiently in real life conditions?

Can the response of the traction control unit be adjusted individually or is there one standard programme?

Last but not least: So far I did not understand if only sparks are cut or also the fuel. Would you happen to know? I am just worried about fuel constantly being pumped into the engine and sparks being left out for some intervals.

I shall be thankful in case you can help me along with some answers as I am sort of lost whilst choosing THE traction control for my Cobra.......

My car has very sticky tires (Goodyear road race rain tires) and a cam that does not produce excessive torque at lower RPMs. This, no doubt, is the best "traction control" feature on my car. The FAST XFI system has two modes:

1) A driveshaft speed change mode that retards the ignition timing. This is the mode that I am using and its more designed to avoid wheel spins when changing gears or on less than good pavement. You can pull as much timing out of the motor as you need to to limit toque output. I'd say that its possible to reduce the torque output by as much as 30-35% using this method.

2) A Drag Race mode where you create a driveshaft speed based profile from a dead stop and limit drive shaft speed to this profile. In this mode, individual cyclinders are not fired at all to keep things under control

The fast XFI has an option to store up to 4 seperate programs for everything (including the traction control). You can switch these prior to starting the car. I have the switch on my car but I have not found a need to use multiple programs to date.

I think that the case 1) traction control that I am using is good for controlling traction loss on a well set up car in unusal conditions (ex too much torque being applied out of a corner and breaking the rear wheels loose). It is not a substitue for a poorly setup combination which cannot put a good bit of the torque that is made to the ground in the first place.

I hope that this helps,
