Q: max dodges max crap. engine tune has everything to do with it because a detuned engine requires more throttle for the same output. while you are correct that a detuned engine may require more throttle the pcm isnt looking for just tps or just rpm. as such the state of engine tune has little effect since the tps and rpm inputs vary independent of one another. this produces an infinite number of possible combinations that the pcm would see. that infinite number of combinations is possible with or without a well tuned engine. youre forgetting the tv cable a large throttle input at low road speed is the classic scenario for a delayed upshift. .

youre forgetting the tv cable a large throttle input at low road speed is the classic scenario for a delayed upshift. not forgetting it at all. if the tv cable were out of adjustment it would happen all the time not just select incidents as the op infers. second it wouldnt happen suddenly as the op mentions unless something broke and then the problem would be constant not selective. further if the cable broke or stretched the shifts would be too soon. as usual youre missing my point im not saying the tv cable is out of adjustment im saying there is a possibility that a sick motor would require more throttle and more throttle means more tv cable extension; the overextended tv cable would delay the upshift. .
