Confirmation that they do it, basically they remap the unit so it doesn't pick up the speed sensor.
But..........they quoted me £50.00, would have to take the unit out and send it to them which would cost £10.00. Or could drive down there (they are based in Leicester), about an hour away from me.
I'm going to put a best offer in on a harness from ebay for £70.00, if I don't get it I will then drive down to these guys.
