Hi all, I'm looking to install an Evo 7 MAF into the CE9A, I couldn't find any reliable info regarding the MAF plug conversion other than buying an adapter harness from the US.

 

Can anyone confirm if the MAF wires are a straight conversion, that is wire 1-1 through to 7-7, as per attached photo?

 

Thanks in advance.

I think you would need to find a pinout diagram for each and go from there?
I wouldn't rely on just swapping them straight over

Understood, thanks  :thumbsup:

 

BTW this upgrade is being done in conjunction with 560cc injectors and Evo 7 ECU, which I know has been done to death, but I'm slowly trying to work through this upgrade myself!

 

So far this is what I've compiled from these and other links, and after a bit more digging I might have found the missing 'Link' and answered my own question??

I've used information from these documents to possibly confirm the straight conversion?

https://linkecu.com/...ation/EVO3 .pdf

https://linkecu.com/...ation/EVO8 .pdf

 

 

2G TURBO MAF (Evo 1-3?)

1 5V Power supply 
2 - Barometric pressure 
3 Air flow sensor 
4 MPI control relay    (EvoLink shows +12V)
5 Ground 
6 Intake air temperature 
7 Volume Air Flow

 

Evo 4-8 AFM

 

1 - +5V

2 - Baro

3 - AFM Signal

4 - +14V           (some show +12V)

5 - Sensor Ground

6 - Ambient Temp

 

Hopefully this information will help others doing the same conversion, but please let me know if I have missed anything here?

 

Thanks again.

I can't remember, but mine is working... Also, my maf ended up with a stuffed atmosphere sensor in it, so I wired one externally.
