You need to go into system mode first I think to make sure the system level is on 4 which has the most options to change stuff. There are 2 ways to get into it; 1: Turn radio off, hold down +, -, & select buttons then turn radio on. 2: With radio on push up and down button at same time and hold for maybe 2 seconds until LCD says system mode. Once in there scroll around until it says System Level and turn it so says 4, then turn radio off then back on or hit direct mode button twice to get out of system mode.
Then scroll up to steering travel for max steering throw, then one after that should be steering balance, you have to turn wheel on radio to right or left for the number % to pop up, then +/- number until your car is set right. Scroll up little more and you're at throttle and brake epa.
