My 60 reg 143 ST is affected by having the EA189 engine.
Not sure exactly how the defeat routine (it's not a device as it's part of the ECU firmware) works, but likely underfuel when rear wheels are stationary to lean up the mixture.
ECUs are simply pulling in data from sensors - wheel speed, engine load, throttle position, manifold vacuum, fuel temperature, pressure etc. etc. and enables each injector to fire for x duration and pressure at z time, so putting in the logic of an anomaly (rear wheels stationary) and underfueling would not be that hard to do...
I have a bluefin map on my Exeo (very pleased with it) and have the option to remove it via the handset.
The question I do have, I guess for bluefin, is will the map still apply or will I have to buy a new one?
I.e take the bluefin map off, reverting to standard, then try and re-apply the bluefin, but the map removed will no longer be the same so might trigger a checksum error and not re-apply the map - dang.
I feel a mail to Bluefin customer services coming on.
Its gotta be what they are planning on doing to "fix" the problem, but will leave us out of pocket in terms of power.
I too have a remap from BHP-UK though. The dealer whos a mate of mine is gonna take the map off before it goes in so its back to standard. But hes confirmed the old remap wont go back on.
see if Bluefin will rewrite you a new map at a discounted price? But we will never get the same power figures again
