Changing UCH - matching ECU needed (Ph1 172)

[Bren Rogers]

Need to swap the locks, ignition barrel and UCH on my ph1, and I'm not sure if I need the matching ECU (from the donor car) as well. Should be any easy one for someone on here, but I'm terrible with electrics.

Cheers guys.

Key, decoder ring and ECU is all you need

Cheers for all the replies guys, I was told there was a UCH on the ph1 so thanks for cleaning that up. I'm picking up everything I need next week of a donor car so hopefully all will go well. I'll be glad to be rid of this dodgy aftermarket alarm/imobiliser

It looks the same as a UCH, but its actually called a Multi Timer Unit on a Ph1. Yes the ECU has to match it. Although, if you had a decoded/virgin ECU, the first time you plug it in it will pick up the code from the multi timer unit and store it, so they would then be matched. If the ECU didnt match the multi timer unit the car would just crank and never fire.

It still has part of the immobiliser in it, I know this as I had to use it to get the Mk1 running using the full Ph1 looms/ECU/key. Decoder ring can be from anything as they are all the same on sports and non sports, they just pick up a keys signal.

I eventually fu*ked it all off and ran the ECU decoded with an emulator.

To the rescue as usual.
