I've spoke to a few race guys who run the FAST and Innovate stand alone systems. They run leaded race fuel but change the sensor every season, a couple are blow thru turbo VW guys. The only real difference, I'm told, is the response of the sensor. The units calibrate themselves every time they are switched on as far as I'm aware. Another tip they told me was to mount the sensor at least 12 inches from an open header end as the turbulance can give false readings.
I'll post results as soon as, but I'll have to fab fancy header extensions as the ends are close to the 'box crossmember / mount. I'm also ordering an extra sensor mount and 2 bungs.
Thanx
