I built one last year with this system. We used a speed sensor mounted in the transmission. Used the park gear as the wheel. Also mounted an accelerometer. Used a SSI4 and the pocket logger to tie it all together. So far it hasn't worked. The sensor is sending a signal as tested with a scope. We have used this method in Dizusters turbo car (different operating system) and in y buddy's Camaro with a TH400. Both work. I can watch the G's go positive and negative when the G meter is tilted. The Pocket logger records data. But no useful data. Inovate has been contacted numerous times. ZERO help, ZERO info. I'll chase it again this spring.
