Dear All,
Last Saturday i successfully integrated the semi automatic mode to my E46 converted with 1JZ with A340E automatic transmission. The car's gear changes can be controlled with flip of the gearknob. Everything else is perfect except for the input signal. I noticed that downshift signal is just right but the upshift signal is a bit retard, like there's a delay of 1 sec before the gearbox respond to shift.
From what i gathered, the stock ECU does retard the upshift signal for whatever protection purposes. My question is can we improve the input signal so that the gear upshift can be faster ? I am not expecting modern day auto GB upshift speed, needed may be lesser delay when i pulled the gearknob down for upshift.
Thanks,
Ken
