Cruise control issue after changing gear set

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.

I'm sorry, but there are no options for this.

Thanks for the clarification. Since this option isn’t currently available, would it make sense to post a request for it in the FlashPro Requests topic?

It’s really hard to drive long distances without cruise control, especially after getting used to it over the years.

You can request it, but it may not be something that is possible.

bump , i have the same request , is it so much complicated to add the gear ratio table fr these carsa 07 tsx? we can live without flat shift ok , but changing gear ratios and losing the cruise and proper per gear tuning is frustrating , arent there many tsx owners interested in this opton?
thank you
