Hello
I have just set-up a DBW throttle on a subaru to try and facilitate power reduction for sequential gear box shift so as not to have to use ignition retard or cut.
Ignition retard/cut causes an issue with my set-up where i am not running an intercooler and spraying Methanol in the pipe work right after turbo, this fuel air mixture was being ignited by the backfire which blows exhaust vales open while inlets are open and blows apart pipework etc !(apart from other destructive issues at this boost/power level)
Previously i have been using close loop gear shift with a 75 degree retard, with the DBW setup i plan on using some retard(mybe 50degree's !??) and throttle reduction, but it seems the throttle reduction is based purely on timings, not closed loop(next stable gear).... is there a way to make the throttle movement closed loop rather that purely timings?
Any other suggestions to make this set-up work well, i have not had a chance to test DBW shift set-up in anger yet...and will likely get limited testing before event....its very hard to find a venue to test launch and shift with close to 800hp atw. I need to know everything possible so as to shorten the learning curve on getting this working right.
Cheers
