Paul,

It's a bosch motronic ecu - it's just a different protocol than they were expecting. Rather like buying some software for your PC that needs vista to run but you've only got windows XP.

There are four ways of doing a remap as far as I'm aware.

1) downloading a new map using the protocol in the ECU - this is the preferred way as it's the least intrusive.

2) open the ECU and talk directly to the chip finding the tables in the memory on the chip and updating them - this is a lot more intrusive and as your dealer won't ever open the ecu - generally noticable.

3) open the ECU and swap the chip out for one with a new map on it - very noticable.

4) piggyback system - whereby the new ECU overrides the signals sent from the factory ecu - think diesel tuning boxes.

I assume Autodelta are either doing 2 or probably 3 it's either that or they have information that other tuners don't and would seriously like to have...

Owners of Citroen C2's VTS/VTR's would come running...

Nice day to be sat working at home - although I trapped a nerve in my back last night and it's not comfortable going over speedbumps/potholes as a passenger in the brera.
