I want to install to additional gauges in my 09 SS/TC and keep the stock RPD. I want to be able to read AFR/KR/Boost all the time. Does the RPD have the same accuracy of an aftermarket wide band?
I'm thinking in adding a boost gauge to have the vacuum reading and a aeroforce interceptor for the kr and keep the RPD for AFR readings. Opinion needed, I don't know the accuracy of the RPD

 

i was thinking about this. in for answers

 

The rpd displays simply what the ecm reads from the wideband and other sensors. If the reading is off then the sensor is off.

 

The only thing inaccurate about the RPD is the torque reading and knock, I have never seen it show knock even if datalogging it and seeing knock.

 

RPD's RULE!!!!

 

yeah this is true, iv seen 4 degrees on my rpd and showing 8 on my computer lol

just get a interceptor

 

Torque numbers off after a tune or always?

 

There's a total of 6 knock related pids in hptuners, 4 of them show kr in each cylinder while one shows total kr and the other just retard. I've seen instances where i see 1.5kr in one cylinder, the retard pid shows 1.5kr but the total kr pid shows 0. Which one the rpd shows i have no idea.

 

Sub'd for answers.. since I have an RPD and am also curious.

 

Did anybody test the accuracy of the stock wide band reading vs an aftermarket one? Maybe in a dyno sesion...

 

The factory wideband is accurate.

 

What about the engine horse power? At WOT I'm at like 295-300. Is that acurate? I know its not WHP.
