[Rovernet] SD1 Advice and ECU

[Fletcher Millmore]

I think it is likely a waste of time. If the engines are identical, the 
fuel requirements and therefore the ECU should be as well; if they are 
different, there is little reason to believe that the UK unit will be 
correct for the US engine. Might be some slight improvement in 
driveability under some conditions if the US unit is optimized for 
emissions, but these usually have little effect on power once to 
temperature. I can't imagine that any piece from a totally different 
engine, eg Jaguar, could possibly be right for the Rover engine.

More on the TPS: on a 3.8 Ford Taurus, I found that the TPS was causing 
bizarre and random idle characteristics, apparently common but cause 
unknown to most Ford dealers and owners. When I replaced it, I gained 
about 20-25% fuel mileage (from 27 up to 33mpg in daily use) AND power, 
and the autobox shift points all corrected and stabilised themselves, 
for a great improvement - cost $28 and 5 minutes to change. I've had 
similar results on a couple of Mazdas on the TPS too.  I also found a 
bad knock sensor on one Taurus, and that also had a great effect on 
performance and economy (not all cars have knock sensors).
