Many thanks in advance,

Greetings,

I don't know of anyone that's running the stock ECU, though I'm sure it could be possible. Most folks on this list are probably using Tracy's engine computer, which is a fine system, designed for the job. The radiator in the car would be too small for aircraft use. Some people are using a large aftermarket radiator, though most are using air conditioner evaporator cores.

I would take the engine, the intake manifolds, fuel rails, throttle body, exhaust manifold and turbo (if you plan to use the turbo). If the car happened to have an automatic transmission, get the flex plate and flywheel.

Anything else guys? What did I miss?

Actually, I believe Perry Mick is flying with a stock ECU in his ducted fan Long EZ.

Yes Ed I am still using it. Just some observations, FWIW:
