cheers man...are u refering pin 1 to filter end or opposite end...cheers

[RB30-POWER]

If you look carefully it should have a number 1 printed on the connector. (It will be small writing).

Otherwise measure what wire has +12V with the ignition switched on.

Maybe someone else knows what end?

(I dont have a 3 pin AFM here at the moment sorry)

thanks man, do u have any experience with wiring in a z32 into a r33 s2 with an apex'i power fc? because the engine light keeps flashing and the fuel pump is going non stop? what the! there is no ignition or fuel maps either after we done a tune last night and it was running fine before the z32?

[paulr33]

engline light flashes constantly? even at idle?

[nissan_skyline69]

we connected up the std air flow metre and now it wont start at all... what the?

[paulr33]

you've reset selected the RB25 o item ?

[nissan_skyline69]

it doesnt matter what value we select eg. std r33, z32, qf45. the engine warning lights are flashing and there is no ignition or fuel maps....what the?

[paulr33]

sounds like you've fried something

does the hand controller come up if you turn key to ACC

like can you scroll around etc in the menu's ?

[nissan_skyline69]

yeah the hand controller has all the features but it has no maps and its slow to load up map screen and freezes when u get into the map.

i've never heard of an apex'i fry even if the afm wire was wrong!

[paulr33]

by no maps do you mean its all 0's or its blank or you cant choose the menu option ?
