Hi vib_ribbon,
The first thing to now is the value of the Pot inside your game.
Check on your game, and see the value of the pot(s), usually written on its back


I've only worked on two sega games : Turbo Outrun and Daytona USA. Both use 5K as pot value for the driving wheel + pedals.
And probably many others SEGA racing games uses similar pot (5K)
On the Ultimarc Website you can read this :
Pot Value Capacitor Markings
5K 150nF .15 Supplied with board
100K 10nF 10n Supplied with board
50K 15nF On request
10K 68nF 68n On requestBecause the common pot are 5K and 100K, Ultimarc provides Capacitors for these values when you order an A-Pac.
Be sure to order extra capacitor, as many as you have pot of course

Hope it can help
