Hi recently purchased this for my mk3 ep82 and was unaware it needed two wires on the loom swapped to run a mk1 ecu.im currently waiting and trying to get a field harness to get this fitted
thanks
thanks
Mk1, Mk2 & Mk3 ECU's are interchangeable as the pins are in the same position? The intake pressure pin definitely is..
I'm going to move this into the tech section and remove all sales suggestions as :
1) Advertising in this section isn't permitted.
2) It smells like you're attracted a few technical types.
3) Gauging interest threads are pointless, sales threads are where it's at!

Hi jay .
I've got a copy of the ecu pin outs it seems the mk1 ecu wiring is slightly different.
Any help appreciated
Hi thanks very much for the replys
Here's the link

Much appreciated.
link dont work mate
is that just a link to stock 4efte pinout or the hrf u have
Actually...this pdf http://homepage.ntlworld.com/dub.se7en/TGTT/ecus_4E-FTE.pdf does show a slight difference in the mk1 and mk2 ep82 ecu pin outs.
Righto, I can see where I fucked up looking at them before lol.. all of this is theoretical and I would prefer someone else doublechecked it for us all but here goes:
Everything on the big plug is exactly the same. The difference is on the smaller plug. They look to have moved the aircon (AC1) to a pin that was vacant on the earlier connector and shifted the boost control (BC) pin down to the pin where it used to be. Then where the BC pin was they added a pin for diagnostic purposes (TE2).
So in theory you can correct the boost reading by swapping the wire leading to pin 15 over to pin 7. Your aircon wire should then head to pin 15 instead of the 12 that it's in now.
That will still leave you the TE2 issue but I'm not 100% what effect that would have. At a guess you might not get full function of the diagnostics but it's hard to predict.
I haven't found any easy way of re-pinning the connector blocks so cutting wires might be your best option.
