VL RB30ET cold start issues

[Matt]

RB30 ECUs use a 1.5 - 6.5v MAF signal from factory (RB30 MAF)

When Z32 etc is installed, we cut pin 14 from OPAMP board, which makes the voltage now 0-5V input

Normally when MAF is changed, it should remove the 1.5V offset we add to the RB30 ECU (shown in the software) to make 0-5V range

You can hard switch it off in the software, right click VQ map and disable MAF offset

Proper (N62) Z32 MAF is about 350-370rwkw maximum. So it would be 5V around this load range

Thanks mate.

This is a genuine RE manufactured Z32 AFM. But maybe it isn’t reading correctly. I doubt I would be making more than 300rwkw at this boost pressure.
