May be possible to use R34 ecu if you are going to replace coils etc and you can get a whole loom and fit it while your engine is out... and Nistune that. Anyone done that?

Coils, CAS and injectors are different..

Might aswell just start with a Neo head..

well he already has a 25de in his car. so I thought that would be the best place to go from.. using that loom and head. cas etc

he has an R32 DE head without VCT? or R33 DE head with VCT?

if he has the R32 head, use the R32 loom and sensors etc and just retune the stock ECU.

Yep, using the head/wiring/sensor setup that already suits the car is the easist way to go but as TiTs said, need to use a Z32 ECU if he wants to Nistune and retain VCT.

its a 33 head with vct.. which he wants to keep. could he just use the z32 ecu and get it chipped or tuned or would he need to get a nistune? (I know thats not the only option, but thats all his budget allows for)

Also with using the z32 ecu, what are the wiring differences that need to be fixed up?

    • 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.
    • 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!
