car wont accelerate after down shift
Posted: Sun Dec 04, 2016 4:49 am
So a few days ago i had a spoon sports 5.3final drive fitted in my cl7 euro r that is supercharged.it uses a second ecu for running the engine.its a dc5 ecu with kpro one.drove the car for a few days with no issue,but i noticed my speedo was way out.so in kpro i changed the final drive to 5.330 and thought if i reduce the speed in kpro by -20% this would solve the problem.but i noticed nothing changed.car still drove great,left the car 24hours,went to drive it.it drives until you try to down shift.if changing down from 3rd to 2nd and the revs for example are at 5k rpm,the first half of the throttle travel does nothing,then it catches up,sounds like it bogs down and accelerates normally.its worse in the first 4 years.if i try and rev match on down change it makes it worse,so i restored all setting to what they where before,but still an issue on down shift.im using a ktuned hall effect tps.i will try and up load a datalog latter.any idea wht it could be?
The tps seems to be working fine if i stay in the same gear,accelerates with no jurkynees.and kpro shows it goes 0 though to 100% and back to 0 with no issue
I also recalibrated the tps,this made no difference.
Here is my calibration,datalog
thanks for your help
