So im trying to log my egr in my hpt and have it all wired up threw the center brown wire the the wire signal coming from wideband.
Next i inserted a user defined pid with the function ([PID.2811]/0.5)+10

I tried with sensor blank and also set as air fuel ratio :1

Then i realised my egr min iat was set to 284* so i set it to -40

Still saying unsupported.

I also tried the second egr pid 2810 to see if it was different for 04+ with no results.

Anyone have any other ideas?
