RPD vs Dual Interceptors!!

So was just wondering this............Does any members out there who have an RPD also have Dual Interceptors OR a Dashdaq as well???

The reason for this is I would like to know the accuracy of the RPD......what I mean is has anyone ever compared at the same time the read out of the RPD to the Dual Interceptor readout at the same time and got two readings that were way off the mark??

Say like the Boost or air to fuel ratio???

How accurate is the RPD on just a stock Cobalt SS Turbo?

How Accurate with the GMS1??

How accurate with a trifectia, HPtuners etc tunes???

Like I said.......Im looking to hear responses from the guys out there with both the RPD and Dual Interceptors or Dashdaq installed??


Lemme know!! OH Canada

The dashdaq/interceptor/rpd all get their info from the ecm, the readings should be identical.

I've got both an RPD and Dashdaq I use.

Interceptors and Dashdaq should read identical. The RPD has some sort of smoothing it does on KR, Baro Pressure, Temps, and a bit on AFR.

Besides the KR, there is no reason to discredit the RPD. When tuned, it doesn't properly display the HP/Torque, but that's not an RPD issue I understand.

Yeah, life's been changing, so it's been a bit harder to find time to get on. I still lurk from time to time though. lol
