Hi Harz I was a clerk of works with the local council and they fitted trackers to the vans they recorded everything from location to speed to gear changing they were fitted to the electrics and throttle pedal when they removed them I spoke to the engineer who said they just took the unit out and that everything went back to normal so good luck with your vehicle but it can't go wrong with the remap anyway
John ?

Yep that's where the speed sensor wires are and my aftermarket cruise picks it up from behind there, well at least you know your ecu will work fine

Thanks Cosworth I thought that was probably the case.

ECU should be here tomorrow so 'IÄll fit that back in and then rip the Siemens thingie out

Thanks as well Rolo

Success guys-please see new thread !
