So, i see no reason why a mspnp designed for a usdm MAF 4age can't be fitted to a JDM aw11 if you repin the connectors. To test this theory i intend to make an adapter loom from a defunct ecu and about 8 inches of engine loom from the connector back.
My research, tracing wiring diagrams and comparing pinouts and the like has led me to this, badly annotated spreadsheet:

see the spreadsheet (minus all the hand drawn bits obviously) here:


now i gotta track down an ecu and loom to test the theory, but while i search does anyone have any suggestions/questions/queries/comments/criticisms etc?

Cheers,
Matt

One of the lads on Toymods has a JDM MAP sensored NA 4AG and has gone this route. Can't remember exactly but pretty sure he went with the Gen2 PNP and yes did not end up keeping his loom, had a whole new one made/chopped and spliced an AFM one to work.
Pretty sure he also ditched his MAP sensor in favor of an MS one.
