Can we do this while the HPFP is on the car? Or should it be removed?

Can be done in the car. Easier if removed.

I have this issue a lot on my Audi as I am running on E 85. Do you connect to a 12 volt car battery? does it matter where plus and minus connects?

Yeah. 12v to the battery direction does not matter. You could be extra cautious if you’re worried about it, and grab the wiring diagram from ERWIN online with a day use account and download every document available for your specific vehicle.

Hello! Im troubleshooting my friends tuned C63 that cuts all power on full throttle, it sets one code Quantity control valve bank 2 - Short circuit to positive. This is the control valve on one of the hp pump. Have you ever heard of this? He is running Spool performance pumps.

Yeah, if the delivered pressure is too high above, or too low below specified parameters, the ECU will shut the throttle and put the car into limp mode. Could be a calibration error, fuel delivery to the pump not functioning correctly (I.E. clogged filter, weak low pressure pump), or a high pressure pump not performing as designed.
