alternative to timing retard during shift
alternative to timing retard during shift
Did you ever make any progress on finding an alternative to timing retard for turbo app's?
Having the boost spike during a shift is not the best for the trans. I tore up a full billet built 4l70 last year. 4L80e going in soon.

Re: alternative to timing retard during shift
Some possible ideas that come to mind are reducing torque by opening the wastegate further, opening a blowoff valve to dump boost, or grab a BMW ASC valve (basically a drive by wire throttle that is normally open, with the ECU closing it - the unit is put in series with a cable operated throttle body) and have it closed while shifting.
