so I installed an rsx cluster in my 88 hatch (b16a swapped), and everything works fine except for the tach. The tachometer works, but whenever i get close to redline (8200) the tach needle goes berserk, it also does it when i am using 2-step before a launch. I also have an autometer tachomether, and that one works perfectly fine, so I don't know if its something that is wrong with the tach, or wiring or if all you rsx ppl have the same problem with your 2step. help
