Use a mechanical stop of some sort. Buy a t stop and just use the adjustments to dial it in. Then when your ready to run in electronics you wont need to buy one. I know a guy with a spare. Or get one of those adjustable mechanical plate set ups. Guess it depends on what youjr trying to do. If you want to run S/ST in your car IMO just get a stop and good controller. If you are looking to run D/Gas sky is the limit, but IMO get a t stop and use it.
