You will need a good multimeter and a lot of patience...

I used the fuel tank pressure sensor it was really simple just use a good ground that also has one of pcm grounds so help eliminate a ground offset I compared the voltages displayed on the hp tuners and the innovate software. There's a good writeup on here somewhere

I've got it setup in the a/c pressure switch, but I keep getting "unsupported parameter" when I start scanning.
The PID I have setup is ([PID.7101]/.33)+7.35

I think it's incorrect, but can't get any info to see if that's true. This is on a 06' GTO if that helps.
