PLease help, Making my speed control purchase today and wanna know how easy is it to make trackside adjustements the the Tekin RS Pro? Do i have to have the link cable and pc for all adjustments or can I drive and make changes trackside then go back out and drive?
I really like the adjustabilty but also need to be able to make trackside adjustments. My other choise is the LRP sphere tc, what do you guys think?
