When I turn on my car (Igntion switch only. Car not running. Measuring ambient air.) and I look at the data page the boost indicates .3 or sometimes .5psi.

Can this be right?

Any ideas.

3 Bar sensor.

 

"Normal."
Even the E6A / E6S / E6K's I've messed with all did that.
At least with the E8, you can always "zero out" the sensor through the compensation tables.

it should vary with alititude/barometric pressure, i think this is why the factory ecu's have 2 sensors, and one is just looking at ambient air

 

Where exactly are you in Canada, what is your elevation?

 

Really. Wow. My Apexi AVCR does not show an offset.

I guess it does not really matter as long as the car is tuned right. I did look at the calibration table for the map sensor but figured I would do more harm then good creating a voltage offset.

I live in Whitby Ontario.

Thanks for the input guys.

Sometimes I ask alot of weird and stupid questions.

 

Ever priced how much just the MAP sensor costs for that thing?
