u have white mini wire that powers system hooked to a full time hot, that's why u are seeing rr with switch off. rr means system ready, not armed. that white wire should be run thru a seperate simple 2 way switch to power the mini only when u want to use it. add a switch in line white wire to turn off rr with key off. flip switch to power system. the tps has 3 wires, looking straight at it the left hand wire is the ecu power input 5 volt wire, the middle is the output wire, the right hand is a ground. mini blue/wht to middle output wire.think it's a brown wire, but cant remember for sure. the r1 when key on means stage one of mini is armed and is awaiting tps activation to spray and is correct reading. u can test to see if system is programmed right and working by programming start rpm to 0 and locking throttle, the solenoid should click loudly on or studder thru cycle programmed in mini, however u set it up. do this with switch on, engine off. solenoid should open between 80-100% wot. if so, u are ready to spray, reset nitrous start rpm to setting of ur choice. checkmate and i went thru some issues programming, but once set up works great. ck mps website for programming instructions if u dont have.
