CDI3 and above use a PWM or frequency based MAF signal for their sensors. Theres no point trying to measure DC voltage on their signal pins, because its a pulse train that is encoding the MAF reading.

This mod only works with CDI2, as they have an analogue voltage for the MAF.

Hay @stumo, great post!!

I’m going to give this a crack, when you say pins 4 and 5… are they left to write? Or numbered? If you could send me a pic of yours plugged in that’d be great.

I’m going to fit a snorkel, so great to get rid of the maf for ease of plumbing. Cheers.
