My E55 shuts down the super charger after one WOT pull. My first thought was to replace the pump but I decided to check things first. I hooked up the STAR and found the effective AIT value in volt. With a warm engine I was reading around 0.5V and after one pull it dropped to 0.22V.

According to this threat I should measure completely different values

Am I missing something??

I also measured the resistants of the sensor and I was reading 1.2ohm (warm engine). The car gives me no fault codes.

Your IC pump has gone bad

FunkTron

I would agree with Shardul.
Check your actual IAT before you go too deep into dissecting the voltages and such.

How do you get this pump to run constantly btw? I wanna get my mechanic to do it when I bring it in to him

I will just change the pump and see if it solves my problem. They only cost 125€ so it's not the end of the world.
Do you need to rewire to have the pump constantly on or is it programmable?

I think mine is dead too . Ambient was ~16oc .

What logging suite is this Supreame?

FunkTron

+1 I like it....but that is such a LONGGGGG period to view

Looks like Torque logging exported to a .CSV file.

supreame

Yep that's what I used .

FunkTron

I've tried a couple times with torque but each time i go to export it gives me an error. I'll have to try a different device.

I log with my android head unit and I always have to save the files to the microSD then pull it and look at the hard file on the PC :-/ The same thing happens when I use my ancient old Samsung Tablet

I guess with certain flavors of droid Torque struggles to export
