I am very tempted to buy a set of these PMO EFI TBs.
Does anybody know if the PMO EFI setup would run with the regular 993 motronic ECU or would I need to get a different ECU setup?

 

I;m sure if you swapped to ITB's you would need to reprogram the ECU. On some cars with ITB's you can stall the car with light throttle, & the car can be very jumpy just off throttle due to the ITB's.

Throttle response should be awesome with them, & I'm sure you would also want to do some other supporting mods to the car.

 

What's the end goal? Just bolting stuff on isn't going to accomplish much. We've got at least 4 or 5 absolutely top end resources here who pretty freely share their expertise. Obviously proceeding with a high-end project has a steep price..................

 

You would have to replace the ecu with an aftermarket system. ITB's will not work with the Motronic ECU.

The Stock ECU uses MAF, throttle position for fuel metering. You don't have the MAF with ITB's amoung other issues.......
