Gents,  There is no doubt as I continually say that tracy's gear and=20
indeed tracy was 20 years ahead of his time.  Being computer illiterate=20
I rely on others to present something like an ECU in a ready to go=20
format.  For that reason I have invested in the Fueltech ECU, but yet to =

wire in.  IS there any on this forum that has already done this? Neil.

It looks very usable for our application. The current firmware and featur=

well as lean cruise. My range would be 12.5:1 to 15.8:1. May be doable.
