Im trying to contact sydney kid for this but here is my problem.

Im connecting into my ECU the jaycar IEBC controller. Ignition and ground are fine as it comes on with ignition. I have injector (I) going to connector 101 and (O) going to connector 25 which is boost. Im confident this is correct. When i start the car it runs like a dog. I disconnect the IEBC controller then it runs fine.

Is there something wrong with my wiring or the IEBC unit?

I'm running a jaycar iebc on mine. I'll just ask you some questions first.

Have you hooked the unit up to power by itself? does it work? turn on? no funny business?

You didn't cut the injector wire did you? you just spliced it on?

I lost the ecu pinout when my computer died.

check your wiring man

see none of the wires are touching

from what i remember the injector wire was a white wire

solenoid/boost was a lite blue one??? i forgot but you cant run the car till uset her up it'll just be shit

so check wiring if fine then just tune her i guess

Yes it powers up fine so my +/- are fine when i ignition on.

Here is the diagram i am using

The injector from memory was the end one which was black and the boost one was a orange one. (no.25)

That's not true. The only output that the iebc controls is the boost solenoid. At idle, whatever the solenoid does, it won't affect running at all. you're not making any boost at idle, so it won't affect anything. The only thing an untuned iebc does wrong is it doesn't keep the boost at the level you set it (even then, it still drives, you just have to use your foot to control boost)

I'm pretty sure I used the same pinout as you. On my car, I think it was boost solenoid, and injector 1 ground. Check your unit, check the soldering. make sure you didn't stuff anything.

sorry I wasn't more helpful

Damn, i didnt build the unit, i bought it off someone!!

      After using a protractor for an actually accurate assessment of what is required,  and by NOT using my uncalibrated eyeball I worked out I need a 25° silicone bend from the TB ro the MAF, but, my choice was either a 30° or a 23° (23° is a weird spec), so I grabbed the 23° one from Raceworks I also grabbed 1mtr of 3" straight from Just Jap, I needed 350mm, but they only had 300mm, or 1mtr lengths....meh Also ordered a 1/2" hose bulkhead fitting from fleabay, this has a smoothish mushroom looking head (they are designed for below the water line of boats) that will fit inside the bend, the hose bit and threaded bit looks to long, but nothing that a hacksaw cannot fix if required, the hose will then just get jamed on the threaded bit up to the retaining nut Fingers crossed and the unsightly amount of hose clamps will be reduced down to 4 once all the parts arrive

      Oil change does not trigger code 21. Code 21 is for coilpacks primary side connection. You can try to clear the code with a battery disconnect, hold down the brake pedal to drain capacitors through the brake lights with the ignition on for 10-15 seconds before you reconnect the battery. I have seen R35 coil conversion permanently cause this code with no ill effects so it might be the resistance it wants to see isn't quite right on one or more coilpacks. Could be inside the ECU, could be the harness, could be a coil. You can test it all if you want or just ignore until the car actually starts misfiring.

      I forgot you have a Nistune ECU. Use Nistune to do all the tests I mentioned instead of faffing with 30+ year old electrical connectors. You can read MAF volts off that too, there are reference values in the service manual to tell you roughly what it should be in different conditions.

      No. I think it might be the AFM. Hence the use of the terms "swaptronics", which implies the use of swapping out electronics for the purpose of diagnosis. It's about the only way to prove that a small/niggling/whatever problem with an AFM or a CAS or similar is actually caused by that AFM/CAS/whatever. A known good item swapped in that still gives the same problem is likely to be caused somewhere else. They're all the same. Spraying AFMs with cleaner is an each way bet between cleaning it and f**king it.

      Can you mount the ATTESA pump in other locations?

      Oh wow! This might actually work amazingly. Do you know the ratio of the diff? I was told the only thing you need to make sure of is if the front & rear diff ratios are the same. Ours is a 4.083 Thanks!
