I stand corrected on which particular gas it was that got recycled..but just the same. Regardless, EGRs were around well before ECMs and such. I have never seen one with wires that would cause it to be contrioled by the comp. Anyway, I dont know everything about the Isuzu motors. Anyway, to the best of my knowledge, it is controled by demand, BUT, I could be wrong. Anyway, I hope this bit of info helps.
