? about PIDs and OBDII Gauge in 06 300C SRT8

[1fastsedan]

I have an 06 300C SRT8 and a U7135 predator running the latest CROM. My question is about what PIDs are coming through and whether an OBDII gauge (like this: http://www.plxdevices.com/products/dm200obd/ or http://www.aeroforcetech.com/index.html) would be able to read boost from the MAP sensor and/or fuel pressure from the CAN system. Or do I need dedicated gauges with their own senders?

Thanks.

No - those gauges don't have a fuel pressure PID, that needs a pressure sensor and gauge for that. The MAP will read boost but it would be in a value over 100kpa /14.5 psi.

OK, so there's no fuel pressure PID. What do you mean about the boost reading? You mean it adds forced induction boost to atmospheric pressure? So if I'm running 5 lbs. of boost, it will read 19.5 psi? If so, that will work for what I need. Thanks!

You are correct. Go for it.
