The ECU is not an issue, because we have a pretty advanced piggy back that takes the OEM values and tunes them to the needed specs. It just uses the signals from the ECU from a given wire (let's say the Crank sensor) and then tunes the input and output to allow for boost (or more/less fuel, timing, error cancelation... and so on)
