I have a CPS and a crank trigger I want to run it sequential. I see they sell a selector switch so that you can switch between 4 tunes with out a laptop . If I read it correct. I plan on using a pump gas tune, E85 tune, race gas tune, Maybe a methanol tune. Also looks like the NTK sensors would be the best for this application?
