PowerFC Map Tuning - Reliability?


Recommended Posts

Hey all,

When using a PowerFC, are you running a lot more of a risk of detonation because you no longer have the protection of the stock ecu - SAFC combo which will protect the car by pulling timing when it senses knocking?

Does the PowerFC still use the knock sensor to protect the engine to some degree??

When an experienced tuner tunes the PowerFC, can they really map out all of the ignition and fuel maps in a few hours on the dyno? Aren't they 3D with a sh1tload of different scenarios based on heaps of diff inputs?

Is it really possible to have it all mapped out with smooth and safe results on the road??

Don't get me wrong, I don't really know, but was just hoping to get some questions answered!!

thanks heaps :D

No. It uses the knock sensor to flash up the engine warning light on your dash, at a knock level which is higher than normal but should still be safe. Thus if it only just comes on due to a bad tune or bad batch of fuel, it shouldn't insta-kill your engine. (in theory)

Yes.
