Guys. I want to use the AU ACT/MAP Sensor I have. Is the MAP Signal the same as the EF One? - or is this just a nono

I don't know and I could not find out when I did mine so elected for the E series MAP. Someone that did an AU conversion and tried it but failed and had to go to the E series map.

*bugger* - its such a nice clean solution.

Im putting that one temporarily in the too hard basket - Im going out today to buy a 6mm hex socket driver to change the plennums over.

Thanks

The AU TMAP is analogue. It signals manifold vacuum by a variable voltage nominally between 0 and +5V, in practice normally between +0.2V and +4.8V.

The E-series MAP OTOH is digital and generates a range of frequencies varying with manifold vacuum (sorta like musical notes). And of course the E-series ECU expects digital frequency not analogue voltage.

So no, you can't use an AU TMAP on an E-series ECU as a direct replacement for the MAP. Put that one permanently in the too hard basket unfortunately.
