Program change for Increased Tire Diameter?

TylerDurden · 01-12-2020, 10:40 AM

I replaced the stock tires/wheels on my 2015 RXV. The new tires are 20 inches in diameter. I chose that size based on BobBoyce's recommendation of no more than 20.5 inch diameter tires with a stock controller.
Thanks to many in this forum I was able to make a cable and have access to the parameters in the stock Curtis 250amp controller. Is there a parameter that I should change in the controller now that the final drive ration has changed? I would like to get as much torque as possible as I drive up and down some pretty steep hills. I'm not as concerned about increasing top speed although that would be a nice bonus.
