right, before anyone ask's, yes i've done a search and yes i didn't have a clue what they're on about, but different people go different route's with different ecu's, so i'm going to ask how to fit an autometer afr to a my99 ecu. i believe it's the AE801 one? i don't have the afr yet, but should have it in either tomorrow or friday. i'll say it again, i've done the search and got rather confused. has anone at least got a link to THE exact guide i'm looking for?


cheers

I'm assuming the AE801 and AE802 have the same wiring, as they are interchangeable. So...

1. Pull back the carpet in the passenger foot well.
2. Remove the kickplate covering the ECU.
3. Look for the wire - blue plug (B136) pin 21 (third row down, third in from the right, white with silver dots).
4. Either...
a) cut some of the insulation off and solder the purple wire from the AFR onto it.
or...
b) just use a scotch lock connector, as I did, as I'm wnak at soldering
5. If you don't get any disco activity at idle and cruise, then your lambda is probably knackered (as mine was) so don't undo everything you've done, thinking it's something you've done wrong (as I did)[img]images/smilies/mad.gif[/img]

Hope this helps!

Ade.

 

fantastic m8. thanks very much

 

No probs. One other thing, mind you don't slice your fingers to pieces off the kick plate. It's one sharp mtoher ******...!

 

cheers m8. had it off before though, to check it was the original ecu, as i was gonna be fitting a secs at the time and supposedly it wouldn't work otherwise.

 

 

right...now what about the other wires? where did peeps attach them?

 

Cigarette Lighter for Power, then earth to the ECU chassis, and on the same bolt, a big dock off earth cable straight to the Battery

 

cheers, but i didn't get the last bit about a dock or someting

 

LOL

I got one of those big earth strap cables, and connected it from the negative terminal on the battery, to one of the bolts on the ECU casing, and on that same bolt, I connected the earth wire from the AFR Gauge

 

You mean a BIG ****-off cable like this?

that's a BIIIIIIIIIIIIIG cable!

 

Yep thats what mine looks like too, only my cable is black
