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:

Think about car usage, the only time you generally run up into the higher engine RPMs is when you are accelerating. Usually just before a gear shift. I measured the voltage on the O2 sensor and found it is running rich in cruise. I think Mazda does this purposely to get best power during acceleration. The O2 sensor is only used in feedback mode below approx. 3500 RPM (cruise RPM in a car), the only time I am operating there is base-final, and there the mixture was right on stoichiometric.

Running in the 5200 RPM range in cruise I'm burning 7.5 to 8 gph, which is not great power, but I'm sure the fuel burn could be reduced if I had a manual leaning function. I plan to fake out some sensor inputs to see what the effect is on mixture. The ECU does have an atmospheric pressure sensor that automatically compensates for altitude and this works flawlessly up to at least 13,500 ft (the highest I've been so far).
