Hi all,

I was having a good chat with Safechav about the wiring a while back and I have contacted Scort as well via rstmania. Basically the problem comes down to everyone saying something different about the wiring changes. My issue is also made more difficult by the fact I am not 100% sure what my loom was in the first place, but I assume it was a xr3i loom. I am running OFAC management BTW.

a link to the other conversation:

Anyway I eventually managed to squeeze the time in to have a look at the wiring today using the previous conversation as a guide to swapping it about as oppose to the FT guide I did have.

What I have is basically as detailed by Scort on RSBible except I still have my blue/yellow wire (EDIS?) connect to pin 28 on the ECU. Meaning:

27 = CO POT (brown wire)
45 = Map Sensor (brown/yellow)
28 = EDIS Module (blue/yellow)

However I am unable to cold start with my chip on but the car starts and runs fine when the chip is off. It also starts and runs fine with the chip, if a little flat unless it’s very warm, when the engine is warm. The faultfinder also keeps moaning about the Co Pot and this has no affect on the car when its adjusted so I do not believe this is wired in correctly.

I had a chat with Matt Lewis as his company ML Developments originally fitted the engine so he was happy to give advice. He suggested it wasn’t wiring as this would be a problem all the time so was most likely a sensor - particularly the ECT (engine coolant). I have purchased a new one but I am struggling to find a 25mm deep socket to change it over as Halfords stop at 24mm then restart at 27mm

Its not really posed a problem all winter, in fact I have seen it as better as the power has been kept down as a result on the ice roads. However now show season is upon us I want to get it sorted.

Do you all agree the wiring is correct bar the EDIS pin still being there? I also had a good look at the ECU connector and could not get the red connector at the back to come off. Could someone give me a quick lesson on changing/removing pins on the ECU connector - how is it done and will then all fall out? I am assuming the red connector comes off then they are all clipped in again so this does not happen but I want to be sure and know how to get the red connector off
