  • I have a history of tracked data on my MGF VVC (Mems 2J) using Pscan. I can see straight away some differences.

    When oil and water temp > 85 C and at idle of 875rpm (quick extraction of the norms {note that for several readings, the norm can be an either or} but should be enough for you to decipher even without headings)

    The sensor on coolant temp for the ECU is a different sensor to that used for the temp gauge. I have an issue at the moment where the gauge is reading normal but the ECU coolant reading is very different once the temp gauge reaches normal. As both sensors are right next to each other, I am assuming at this stage that the ECU coolant sensor needs replacing.
