Adaptronic and AFM/MAF delete

Hey all,

Yes I know I could ask this question on the Adaptronic Forum and I know Andy will probably respond in his usual fast and friendly manner, however I thought it might be handy for other MX-5 Adaptronic users to reference.

So I now have a 2nd hand e420c Ecu, with the Adaptronic 94-95 plug n play loom. It has a 3 bar map sensor wired into the PnP loom, which should replace the MAF/AFM in my '94. Can I just remove the MAF/AFM or do I need to do any further wiring, or other stuff?

Note that I am installing the ECU before I fit any of the other goodies, so I will using a base '94 map and the only other change will (hopefully) be the MF/AFM delete.

Yep, it's not used so can be eliminated.

- I deleted mine (see http://mx5cartalk.com/forum/viewtopic.php?f=57&t=41091&start=196).

I cut the MAF plug off, shrink-wrapped the wires and tucked them out of the way into my wiring harness loom.

no you need to keep the maf
it has the air temp sensor in it

NBs have a separate air temp sensor to the MAF sensor.

Do NAs really integrate them?

Yes, hence needing a GM AIT + bung for AFM removal.

So, as I have a NA I need to get a Air temp sensor, and bung to fit the temp sensor into the piping before the intake manifold?

Makes sense as I had to the same thing when I had a Link ECU, with FM chip.
