never used fjo nitrous controller. The PROGRESSIVE NITROUS MINI-CONTROLLER combines the functions of our 2-STAGE TPS AND RPM WINDOW SWITCH and our HIGH CURRENT SOLENOID DRIVER all into one very compact module. It can progressively drive two channels, each with a 40 amp load capacity (continuous duty). The device also supports low-voltage OEM, V10 or 3 cylinder TACH signals without the need for additional adapters. It works with most OEM throttle position sensors $150 obo http://i1241.photobucket.com/albums/...ps546793d1.jpg
