P3 Vent Gauge

O Stater · 05-02-2023, 09:02 PM

Anyone using the P3 on their F22 car?

If so, are you also using it to detect the ethanol content?

Also, if you are running it, did you run the vacuum line for the boost pressure or just using the cars factory sensors?

I want to get a P3 so I can monitor my IAT and Boost as well as dabble with E30 or E50 blends but sometimes the all in one tool doesn't always do the best job.

I run a P3 (OBD2) in my F23. It does not do Ethanol content unless you can find an analog sensor to attach to it for those functions. It can handle two of them. I have not added any and just use the cars sensors for Boost, EGT and IAT. Bimmer-link may be a better alternative.
