Just noticed that with the engine off the MAP is reading 3kPa vacuum. I haven't paid attention to it in a while since it's been running well for over a year since the last major tuning but I'm pretty sure it used to read 0 when the car was off.

Anyone else have the internal MAP drift? Failure? Is there a way to re-zero it?

I'm hoping I don't have to switch to an external.

Thanks!

you should be able to calibrate the sensor. check it out

I really don't want to change the internal map calibration table at this point. I assume that's what you are suggesting.

Just want to see if others have seen the internal MAP reading drift over time and what they've done about it.

mine use to wander a bit, i attributed it to changes in barometric pressure which makes sence if you think about it. it never once gave me an issue fwiw
