As mentioned, can you not get an ECU bespoke made to match your requirements.I had a Megasquirt ECU custom made for one of my cars (mazda MX5 MK1 Turbo) requirements, specifically designed to suit my custom Turbo install. Should cost alot less. Off the top of my head try Link ECU or Megasquirt. I know of a Range Rover running Megasquirt and it was designed to increase the cars power. James.
You should bypass the dealers and call up Jeep UK customer services.
The ecu was sent to BBA-Reman who sent it off to Bosch, they diagnosed it as faulty. Ive read on other sites and from one of the breakers that it has to be an exact part, the unit fitted to the 2003 model is different to the 2002, 2004 modesl etc.
ok as its a merc engine would it be useful contacting them?
how about taking a pic of th ecu and posting it on here and fellow jeepers can see if they run a similar ecu or if the one they have has the same connectors?
I have ordered a new ecu (697.50 plus vat) which should be here by early next week (they are coming from germany). I did enquire with them about setting it up they wanted 150 plus vat, the auto electrician wants 80 so i think it will be going back to him. Im now over a thousand pounds down on the car.
