Yes, if you can spin the tires in 3rd and 4th (easy with a turbo car in the rain) then traction control would be of use. The SAE paper on the lamborghini F1 system showed that the system allowed up to 2% slip to almost 60 mph if I recall right. It allowed more if the car was turning.

This would be a great place to put a thermocouple for egt sensing. What i would like to know is is there some way of putting a thermocouple in this port so that i can measure the exhaust temperature, and if so, how could i go about fitting this in the port. I've thought about drilling the centre of a bolt out so that i could run the wire through this, and the end poking into the exhaust. The issue of insulation would come into this. The only way that i could think of insulation between the wires at these temps is by ceramic fillers of some sort. Do such exist? Is there some way of fastening a thermocouple into a threaded hole that someone has come up with already? There being 4 ports for the EGR, it could be possible to measure the temp of each cyliner individually, and RIGHT AT the port. Any comments would be most appreciated. Thanks. Bruno. (b.marzano@xxx.au) Smile. It makes people wonder what you are thinking about. ------------------------------ End of DIY_EFI Digest V1 #309 ***************************** To subscribe to DIY_EFI-Digest, send the command: subscribe diy_efi-digest in the body of a message to "Majordomo@xxx.
