Title: apexi afc neo and euro ecu wiring?
Post by: Kamatari on April 18, 2011, 05:00:24 PM
Hi guys, having a slight problem trying to wire in the afc to my ecu, the diagrams I\'ve got from apexi show one of the wiring blocks to have more pins than mine has so I\'m just wondering if there is some euro wiring guide?

My ecu is n322 18 881c if that\'s any help!

Thanks!

just to quickly expand on it:
(http://www.1300cc.com/howto/how2/safc/ecu.jpg)

if you look at the left image, the first two blocks seem right but the last block is i think about 14p and not 24 and where it shows the rpm signal, there is nothing in that hole, I could wire everything else up and if it just means i dont have the afc showing my rpms then thats fine but i want to make sure that everything else is the same and the uk ecu is not completely different!

Thanks

early UK car runs a dizzy and not CAS and this may well be where the fundamental differences lay
if you hooked up the coil negative to that missing input am not so sure you wont be getting a double rpms signal
( actually now i think about it it may well work out as the same number of pulses per rpm )

try instead hooking that missing input to the coil or tacho wiring

Cheers for the reply, got that part sorted now, for anyone wondering just use the pin above where it shows the rpm :)

My new problem is that i cant get the car to start with the air flow signal wires connected but it starts fine with the original wires connected, the decive is set to 4cylinder and throttle to top right, sensor type is flap and set to 5in and 5out, ive also tried 6in 6out with no luck....it looks as if it is getting the right voltages so im assuming its a setting on the afc

just a note for brit users,, n322 appears to use a 12v afm and thus is not compatible with the SAFC intended for US and oz and japanese FCs ( 5v )
