Hey Greg I have your nitrous harness hookup, recent install with 50 hp dry shot with spray bar in air box from Gixxer. Use Zex system have the large Zex solenoid wired to your harness feeding back of air box with shot. Went to track this week end, we had a cool snap hre in Phoenix if you can believe that. Bottle pressures low 700lb not good for shot, did not have bottle warmer. Long story short would like to try new harness for 2nd gear activation at horn button. I use a co2 system with MPS Autobox and MPS electric valve. I also use your interface equipment to remapp. I do it on the bench before track time. I keep 2 ECU's to have two set ups at track. Stil A little poor with all these race parts needed to buy laptop. LOL Drop me a line if i can help, I am certified maechanic with DVOM. Dont have dyno set up. But i do have the balls just to put it on and run it. Is that balls or stupidity? only time will tell.
