This part makes no sense. The ECU reads signals from the MAF, which itself converts the velocity of the air that goes past the wire in the MAF into a voltage. This is what the ECU uses to tweak AFR as a function of throttle position. With this in mind, it might be useful to use an SRT6 MAF, which I am assuming could be a little different than the NA coupe version. But yeah, it's the MAF, not the ECU which is generally the problem with most motronic-based systems that I am aware of.
