No lies Sir, though mine used to be an auto and I made my own loom once upon a time for the instrumentation. Still should not make a difference.nucleustylzlude wrote:You lie boy!

thats odd as most of the pins on the ecu are the same, only a few out put are different iirc!Kie39 wrote:Ok! so the four plug ECU did not work. Car starts fine but zero throttle response.
Looks like were back to where we started!
@wurlycorner If you have a spare 3 plug ECU are you still interested in a swap???

Yep, happy with that.Kie39 wrote:Ok! so the four plug ECU did not work. Car starts fine but zero throttle response.

I am surprised that you have a problem with the throttle though - Lisa's Lude is a 4-plug TCS lude that was running a 3 plug ECU when we bought it. I swapped a 4-plug ECU in no problem.
I also converted someone else's lude on here that was a TCS 4 plug ECU car to running a 3-plug ECU and the only thing I had to do, was to swap a couple of wires over to get the speedo (or tacho? I forget which, now!) to work.
Did we ever suss out what ECU code it was that you needed? I need to check I have the right 3-plug one that you need!

I think 3JO or 3NO would be ok from what has been said . So long as it is off a jdm 2.2 manual.
There was a small box attached to cables off the four plug unit so maybe this was required to be rewired into cables of car.
I be honest I'm no mechanic by any means . The track car is mine and father in laws, he's the mechanic doing all the work on it so unsure on the speedo cable. From previous issues with car though where speedo was not connected I'm sure he would have checked this.

Mini thread hijack, but I've got a P13 3J0 4-plug ECU that has had a Darf chip in for years from way back, pretty sure these are the same things. Only I need a new one
For some reason I'm only getting about 0.1V out on the MIL blue/white which isn't enough to light the CEL lamp. I've had a look inside it and can't see anything obviously wrong and am not brave enough with electronics to delve deeper in than taking the cover off and looking so think i'll bite the bullet and get a new one. But I want to retain the chip Has anyone got a 3J0 that has been socketed and/or already has a chip fitted available?

Unplug the ECU, get a multimeter set to resistance test (ohms) stick one terminal on a chassis ground (door lock bolts on the B pillar are a good one nearby) and the other on the correct pin feeding out of the ECU plug.
See what it says.
There won't be much resistance in the circuit (might only be around 1 ohm) but if you get 0 or 0.1, then you have a short.
