Converting to Delco from an old aftermarket ECU

[Jackson.]

Weird. I could see the image. What about now?


SO if i was to source an LD Astra from 1989. I basically pretend I'm using a camira?

In the sense that its all the same steps to follow?

[Dylan]

Same electronics so yeah whichever is easiest to find.

Just done a quick ebay search and found an Astra being wrecked out.

Just a tip if you use a Nissan they have different coloured wiring so you will need to work some things out. The Nissan is also a very long loom with the ECU under the passengers seat.

There's a Pulsar/Astra version of the 12P wiring chart here - http://pcmhacking.net/forums/download/file.php?id=23730

Antus Edit: updated B12 to show 0-5v input, not 0-25v as it was previously

Is this what I'm after?

From a 91 pulsar

[Dylan]

I don't think so. Unless there's a Delco 1227808 inside that box?

[Jackson.]

Nope. Has Japan written all over it

I'm going to assume my dads stripped an n14 instead of an n13

[festy]

I'd say you're probably right, that's not from an N13.
The loom won't need to be cut like that one was, it is separate from the rest of the car's wiring.
N13 is 1986-1990, N14 is 1990-1995 if that helps.

There are two different fuel injected N13s, both use a Delco '808 but one is TBI, the other is MPFI. You want the MPFI one


This is what the TBI engine looks like, note the lack of fuel rail and the old style round air cleaner:

This is an MPFI one - this is what you want for a donor car:

The ecu and wiring harness you posted up is from a n14 with the 1.6 engine.
A bit of useless info for all.
