Boost gauge question??
#4
Nothing definitive, but I just disconnected the upper and went for a drive.
Gauge still worked, vacuum down to 20", but would only boost to about 10 PSI. So I think it was still accurate, but boost was limited.
And no CEL.

The ECU uses input from the MAF, MAPs, engine speed, ambient temp, intake temp and probably more sensors to calculate the boost and torque. Then it sends a PWM signal to the boost gauge.
You could do what RJ did and disconnect them 1 at a time to see what happens.

thanks for doing that. It was very helpful to eliminating t one possible cause of my issue.
