Fitting Z32 maf to '96 classic ?
I've just bought a Z32 maf off ebay complete with the wiring and plug.
Can anyone tell me how to wire it up to a '96 wrx ? |
Z32 connector has 6 pins labelled A to F:
A - Not connected B - MAF Output Signal C - Gnd D - Gnd E - +12V F - Not connected Subaru 92-96 MAF Connector has 5 pins: 1 - +12V 2 - Gnd 3 - Sensor Gnd 4 - MAF Signal 5 - Not connected just make sure you keep the gnds separate.. if the gnds in the wiring loom are connected the powerfc won't power up.. check immobiliser anyone :) Simon |
how do u know which ground is which on the Z32 maf?
|
doesn't matter..
|
Can I just cut the plug off the original maf connector and join the wires up accordingly to the plug that comes with the z32 ?
|
pos 3 on the power fc aswell ;)
|
personnaly I prefer to leave the original plug on and solder into the loom so you can switch between them if you ever need to refit original maf.. but yes you could just cut it off and solder the new one on
|
Is this a simple mod to do or is there anything else thats needed to be done, like the ecu side. And why use a nissan maf, is it better or just down to cost
|
The Z32 maf will support a higher power output than the standard unit...You will need either a remap ala ESL or similar (Simon can sort you out there) or an Apexi Power FC....

By "leave the original plug on and solder into the loom" do you mean that I will have 2 plugs then. The original one and the plug for the Z32 ?

yes.. then you can continue using the car on the original.. switch within 2minutes to map it etc.. and then if you sell the car and want to return it to standard it is an easy plug and play..

Thanks mate. You don't by any chance know what K+N filter I can buy to fit on its own without the kit ? I had a kit but the filter got damaged,just want to buy a filter on it's own ?
but to just replace the filter you would be best speaking with K&N I guess. Simon |

cheers david I believe is wired in yellow (12v), black/green(GND) and green is signal.. or it is the version with red (12v), black (gnd) and white (signal).. haven't found the q45 maf wiring yet though :) |
Q45 MAF only has 3 pins, B, D & E same pin assignment as Z32:
B - MAF Output Signal D - Gnd E - +12V STi4 connector is also 3 pins: 1 - MAF Signal (Colour can vary) 2 - Gnd (Black/Green) 3 - +12v (Green) |
see told you he was the wiring master ;)
|
I meant to ask: why would you want to fit a Q45 MAF to an STi4 ?
Andrew... |
