WILL NOT WORK WITHOUT SOME WAY TO COMPENSATE FOR THE DIFFERENCE IN SIGNALS!

Same as the Z32.

Wiring is the same as the Z32 also I believe.

I agree with Jon , you will not make this work with out some tipe of piggy back like an Apex S-afc to change the signals. But the signals for a Z32 and Q45 are diferent. For a RB20/25 is 4 in 4 out, a Z32 is 2in 2out and Q45 is 1in 1out soyou would have to set up your with the apex as 1 in 4 out. Your can get it from the apex wiring manual herehttp://www.apexi-usa.com/produ...g.pdf

for the wiring I believe http://www.meggala.com has it on his website have not checked to see if wiring is the same yet but you can check here

That you for that info!! I went off of what they said on the aussie boards and it was backwards. After trying your way the car started right up and reved up fine. All I did was set the PFC to the Q45 option. Now I need to go do some street tuning.

did you set the In as 1 for the Q45 and the out as the Skyline ???

If the Q45 worked before and now it dosen't then it's prob a bad maf. Emange is alot better than the AFC. But the AFC will work for what you want to do.
