Paul, and the group

A lot has been written about aftermarket computers for our aero
conversions. However, is there any reason why the stock engine computer
can not be used? Does anyone have any experience in using stock? Good or
bad? How does one go about configuring the stock unit for aircraft use?
Engine is a 13b single turbo with fuel injection.

Thanks and regards,

Perry Mick has over 500 hours with the stock computer. There are a few tricks
however. The stock computer takes in some data from certain places that
don't exist in an airplane. I'll let Perry explain it if he doesn't mind.
As I recall the big hang up is leaning it. Perry was working on a solution
for that as I recall.

BTW HKS makes a bunch of add on device that change the output of the varies
RX8 engine sensors in real time. I suspect they are basically PICAXEs with
analog to digital converters that take in the sensor voltage and covert it to a
different analog output voltage to be fed into the stock OEM computer.
I think this is the way they did it with this 390 HP turbo RX8 engine.

For example if you wanted to lean the OEM computer for use at
high altitude you would take in the mass air flow sensor output voltage
and change it so the the stock OEM computer thought it was getting less
air than it actually was. Consequently it would put out less fuel.
Pretty easy to do with a $30 PICAXE.
