[Diy_efi] TCC control

[elcamino73]

You are far better off using the lock up converter to keep the heat under
control.
If you are looking to control lock up point  try superiors assorted spring
kit. I used it in an 85 and was happy with it. If you can't find a supplier
let me know I'll get you the part number and a phone number.
