im looking for one that controls amount of nitrous in relation to engine rpm so far ive found the jacobs nitrous master mind that requires a aftermarket ignition box or the nos launcher($700) i had no plans to use a ignition box since the 730 ecm has the spark control module and i would only be using it for multiple sparks and the launcher is way to much does anyone know of a different one?
