is how it would be numbered? if i was looking at the ECU.

GhostAccord · 09-01-2008, 03:09 AM

Oh yeah, sorry about that.

On the OBD1 ECU's the numbers are Odd numbers on top & even on bottom.

hon2984 · 09-01-2008, 06:03 AM

much appreciated ghost!

by the way i checked out your ITB thread. Very nice!

how did you find out that you could use those throttle bodies from a suzuki?

i know that you dont have to worry about vtec kicking in because of a CEL
but how do you keep your car from going into limp mode because you dont have an IACV?

GhostAccord · 09-01-2008, 07:28 AM

No problem

As for the throttle bodies, you can use pretty much any throttle body. Be it single, double or quad. As long as it fits your car, you have a way to feed it fuel and tune it.

The ECU ROM (program/basemap) that I will be using will not be looking for an IACV. The two rom editors that I have used, Crome & eCtune, have the ability to disable a number of items such as; IACV, VTEC, IABs, & A/C. Therefore your ECU doesn' throw a CEL if thoes items are removed from your car.

ok thanks but now another question the reason i need this is im trying too hook up an apexi neo afc controler all these abreviations arent really helpin i got power and ground now need to figure whick wire is rpm and throtle..... also arent you missing section d on pin out chart

GhostAccord · 11-06-2009, 11:12 AM

Sorry forgot to copy the D section. I made the correction/edit to above post.

The RPM signal output for fuel hacks does not connect to the ECU. I think the RPM signal wire you are looking for is the BLU wire that goes from the distributor to the back of the gauge cluster. It is the tach rpm signal wire.

The throttle signal aka TPS or throttle position sensor is pin D1 (RED/BLK)

jthrasher1 · 11-06-2009, 11:29 AM

thank god for people like you lol this did the trick allset now thanks again.... and im probly gonna use the blue wire but my buddy told me i could use the crankshaft position sensor is he right or wrong if ya know lemme know thanks...

GhostAccord · 11-06-2009, 12:15 PM

If you are looking for an ECU wire to tap into the Neo diagram that I found shows that you can use the ICM signal from Pin A20 for the RPM signal.
