Cruise control issue after changing gear set
Posted: Wed Aug 13, 2025 6:50 am
Hi everyone,
I’m having an issue with cruise control after replacing the 1st–5th gear set in my transmission with closer ratio gears. Since the change, cruise control doesn’t work in 4th and 5th gears. In 5th gear, it sometimes turns on for a few seconds and holds speed briefly, but then the cruise control light shuts off.
I’m guessing this is due to the different gear ratios, but in the calibration for the 1st gen Acura TSX (using FlashPro), I haven’t found any option to change or adjust the gear ratios.
Is there any version of FlashPro (maybe a beta or developer version) that allows editing the gear ratio values in the calibration?
Thanks in advance for any help or insight.
