Timing Tuner Problem NEED HELP !!
Timing Tuner Problem NEED HELP !! Today I was going over everything to make sure everything is working before taking the car to be tuned . I recently did a H/C swap along with all the boltons and a dyno-tune wet kit , wideband o2 sensor, and the timing tuner .The problem I am having is the car will only run if the minimum RPM switch is set on zero and the #4 mode switch is in the on position . If I try to change the setting on either of the switches the car will stall and will not re-start until I return them to above mentioned settings . If I change them with the engine off the car will not start . I went over all the wiring with a fine toothed comb and everything is correctly wired according to the instructions . The nitrous system works for sure as I removed the fuel line from the spray nozzle and stuck it inside a plastic bottle, placed a vacume cap over the fuel nozzle so there would not be any vacume leaks and with the engine running , I pressed the WOT switch and the solenoids activated which sprayed gas into the bottle , the nitrous bottle is empty because I have not filled it yet . I'm thinking there is something wrong with RPM circuit on the timing tuner that is either grounding out the ignition or opening the crank signal to the computer . Does anyone know if these tuners can be repaired if there is something bad or broken inside ? I would really appreciate some help on this matter so I can get my car back on the road again. 
Here's the update : I spoke with a gentleman at Full Throttle today and explained to him what was happening with the Timing Tuner . He said it is definately a malfunction with the internals and to ship it back to them to be fixed and or replaced under warranty . It's nice to know that some venders actually stand behind their products !
