You would be reading the 4 injector signals and the EGT, and writing the 4 modified injector signals, along with hopefully keeping an eye on your EGT to make sure you aren't cooking anything, right?
Hmmmmm.... don't know about that.
You have to remember that all of these aftermarket power chips are installed post ECU, so the ECU does not actually know that they exist. I have no idea how, or if, the ECU compensates for anything that the power chip does.
The ideal setup would be to remap the ECU, as this would give you the extra power but also utilize all of the safety features that are built into the unit. Alas, finding someone that can do this without bricking the ECU is the challenge.
