Silly question of the day... What's "ATB" ??

Considering TC isnt in the ECU I cant see the problem being there.

As for "bricked" ECUs.. They can be unbricked quite cheaply...

Send it to Gary (Alive) or Pete (BAS)

There are 2 feed wires from the ECU to the WABCO ECU
Does the mapping have the ability to remove the feed hence the TC would stop working.

From RAVE relating to traction control

The ECM provides the ABS ECU with a Pulse Width modulated (PWM) Signal on an SP wire. This signal includes information on engine torque, engine throttle, engine type and throttle type.

The ECM provides the ABS ECU with pulsed voltage signal on a YK wire. The signal informs the ABS ECU of engine speed, The ECM provides the ABS ECU with two voltage pulses per engine revolution.

The Engine Mapping area is a very small area (~16k) which is the only file area touched when tuning.

The tuners (units) only target this area...

Other sections of the board are not even accessed.

Yep. That's why I suggested it wouldn't be the map.

Thanks for your input but what about this thread http://www.aulro.com/afvb/90-110-130...cu-fitted.html

Tends to suggest otherwise??

From memory Josh was running a Disco ecu when he had his problems... Swapped back to a Defender and all ok again.

Disco's use a different ABS system, hence his didn't work.

If you read right to the end I think he says what the problem was, unless he told me that via PM, not sure.
