From what I have read about the uni-chip it only takes over at high rpm when there is a risk of running lean. It's not a sophisticated piece of kit. I think it only splices into 3 wires from the loom off the ECU. I don't believe the original ECU was remapped but I may be wrong?
Morning have been doing some reading it does say if it spliced into ecu it can ruin things removing it defo if you got cams and pulleys.so need ring round.do u have train station close by?
Mornin' Birmingham international train station is right by M42 J6.

If all is good then I do want to buy I have the money here.but being a bank holiday I can't get hold no one.i no ur engine will work in my car with supercharger but for me it what I do about the piggy back ecu from urs and mine and what ever the dicision also who will tune it at the end
