I have done a bit of tuning on the car now and I can drive it. I still can't use full throttle/boost but I'm slowly working up to it. I have a few issuses to sort out. Number one is some form of intercooling, my inlet temps range from 60deg to 100deg. Next will be bigger injectors although I'm yet to find the actual limit of the standard ones. (the engine hasn't been past 2500rpm with full throttle).

I may also need an external waste gate. I locked the internal gate open so I could get the base tuning sorted and the turbo still makes 9 psi boost over 3500rpm.

Other than that I can report that the megasquirt is happily coexisting with the factory ecu and all the factory functions are still working fine (Auto, Gauges, Trip computer, etc). The engine starts fine even from cold with just the base start and warm up settings in the megasquirt.

Cheers

Daniel.

Good stuff, progress is a good thing.

Are you tuning it with a dyno, or just on the road with a laptop?

Just tuning on the street. I use the brakes or hills when I need to load it up. Megasquirts have some handy logging and tuning software.
