Lude Generation

Hi, I am finishing my engine swap and bought a P13J 50 ECU with TCS, it form auto Prelude, and I need to convert it to run with manual gearbox, with possibility to have TSC.
I have google'ed some how to descriptions, but non of them was about converting JDM ecu with TCS to manual.
Can anyone help me with that?

Doesn't the TCS require a 4 connector loom? Regular looms are 3 connector.


By all accounts the TCS is a bag of crap anyway

Yes, TCS requires a 4 connector loom. I assume it gets an additional feed from the ABS ECU, or direct from the front wheel speed sensors?

I still haven't tried it out on Lisa's lude since I fixed it last year!

I do not want to damage the ECU, I will be selling in after some time, because I already have P28. But for the firs start and test drives I need this one to work with manual gearbox. Any suggestions?
If I use this tutorial will TCS work?

Don't use it and get a non-TCS manual JDM P13 instead.

I would think that unless your car has a 4th connector on the loom for the TCS it will not work.

That's correct.

Also if you're trying to use a 4 plug ECU on a 3 plug car, I think your rev counter is unlikely to work (that's what happens when you try to use a 3 plug ECU on a 4 plug car anyway, so I can't see why the same wouldn't be true in reverse).

If you have a 3 plug loom, honestly the simplest thing would be to buy a 3 plug manual P13 ECU. You should be able to pick one up very cheaply on here (no one buys them because they're ten a penny/don't go wrong/people only look to buy chipped ones). If you had to pay more than £20 I'd be surprised?

I've tested this and it was not a problem, rev counter or otherwise.

I'm assuming the OP has bought a 4 plug ECU because he has a 4 plug loom? If this is the case, and the conversion is pretty simple, you can always try it out and if it does not work put it back to original.

Curious... Why would one way work ok and the other not!

I am using 3 plug loom, to make it clear. Fallowing the manual, I should move jumper wire form one place to another and will have a manual ECU and I can use it in 3 plug loom

Maybe, though I think the potential issue is no one is entirely sure if the TCS ECU will work as expected if converted to a manual. Personally I think it will be ok.
