AVC-R Boost with engine off.....not quite zero?

[jspaeth]

Hey......

I have 2 APEX'i pressure sensors........why?....because the AVC-R boost controller is better than the PFC's built-in boost control.

1) First one goes to my D-Jetro PFC.......with the car off, the commander reads -14 mmHg

2) Second one goes to my AVC-R....reads +0.04 kg/cm^2, or +30 mmHg


When I start the car, and it is in vacuum, the PFC continues to read about 40 mmHg LOWER than the AVC-R....

Does anyone else experience pressures that are not EXACTLY zero with the car off?

The PFC reading is most important, as the tune is based off of that...

It's not far enough off where there is some major wiring issue.....maybe that is just within the tolerance of the pressure sensor?

I mean 40 mmHg is only like 0.8 psi.....but it would be nice if they agreed better....
