I didn't read his comments to say ALL ECUs, just the ones in these vehicles. Most vehicles with ECUs don't have this kind of stalling problem.

I have seen tons of problems with a range of ECU's, particularly GM. GM had a run of ECU's that were very dangerous in that they would stall (die) under full speed freeway conditions if you lifted your foot from the pedal.

I fought the f***ing dealership for a long time on this, and they didnt even read the bulletins.

Finally, I got to the right guy at GM and he roasted the dealer over the coals, but got me a new ECU under warranty which cured the problem.

We went electronic because it was powerful and simple. There were certainly mechanical systems, even with FI. Fluids computers might have been able to take some of the trouble out of the system.

Military standards for components would have helped insure that the damn ECUs would work longer than a string of Christmas lights. But this might have been very expensive. Adequate quality would not have been expensive and could have removed most of the problems.

Basically fluidics devices, amplifiers, sensors are passive devices which can handle some logic jobs.
