P3 Question
Will a C7 Stingray with added 7 psi boost supercharger read boost on a P3 from the ECM with the standard map sensor or does it require an added external boost sensor?
Thanks, installing a P3 and want to wire anything extra at the same time.

When I bought my P3 3 or 4 years ago, yes that was the case. I had to buy their circuit that converts the frequency that comes off of the fuel composition sensor to a voltage.
I just looked at the P3 web site and it looks like the gauge may now read the ethanol % off of the OBD port but I'd verify that.
In any case, I really like the gauge and it worked flawlessly since I installed it.
