Button: You are correct with the Hotwire ECU, however, if you replace the chip with a Tornado Chip you open up the system to be adaptive and learn. It makes a difference as long as you change the other components too allowing the engine to breath/fart and enjoy itself!!
Don't understand the "Tornado Chip" yet. But it must revise the MAP to something more suitable for a light Sports Car.
I have two modifications in My Mind to adapt My MSD TB EFI to insure it is supplied with cool, fresh air and not engine compartment air. 1. Build duct work from above the radiator to the big round carb type air filter. 2. Buy or fabricate a housing for the top of the MSD Unit and pipe it into the Rover Filter (sealing off the heat riser hole) and locate the Venturi Mouth just in front and above the rad. And then monitor the AIT Temp on the MSD handheld to ascertain how close this temp is to ambient temp.
