Was there ever a recall of the ECU, and if not, why did the UA events go away? Were UA events more common at higher elevations, where there would be more cosmic ray activity?
This story is like Baba Yaga, it comes out from the shadows to scare people every now and then, but Barr’s theory has the interesting property that the ECU would be cleared by the error and so there could never be evidence of the event as he postulated.
There was an ECU update but not a recall. There's thousands of these old ECUs driving cars that are still on the road. Yet somehow they never misbehaved after the mass hysteria and legal circus was over and forgotten. Hmm.
