Not as bad as first gear. The torque in the lower gear (1st) would be the most severe, theen second will be a tad softer of a hit after your moving. That's one of the main reasons guys lock out 1st gear, breakage and/or traction. I run 1st stage in 1st gear, then lock out 2nd stage in 1st gear and wait till I shift into 2nd gear. A great way to get a bigger more powerfull hit to work with any car.

The switch doesn't know which gear you're in. When you set it up you set an RPM threshold that you have to break in order for it to come on.

I guess I am confused. if I set it to come on at 3500 that will be in every gear? so how does the gear lock out work?

Gear lockout doesn't know what gear you are in. It does not activate the nitrous until a preset RPM is reached (say 5800rpm). Once the controller sees that preset rpm which subsequently drops from the upshift, it then activates the nitrous. This is what myfast70 is referring to as the threshold. If you set the gear lock out to be functional, it will not allow the nitrous to activate in the first gear that you are starting out in while racing. IE if you start out in second gear while racing on the highway, the gear lockout has no idea that you are in second gear. So it will not allow the nitrous to activate until this threshold is met and activates the nitrous for 3rd gear.

What trans do you have? If its an auto and you want to try and keep it together for a little longer, you can set your window switch to not spray through the gears.

Basically, if you set your spray threshold to come on at 3500 RPM and have the gear lockout active for first gear, your engine would have to rev past 3500 one time and then the spray would activate on the second time. If you have first and second gear lockout, then it would spray on the third time past 3500 rpms. So, if your on the street and start out in second gear, your nitrous wouldn't spray until third gear if set for first gear lockout. It's really only useful if you only spray on the track.

Really easy! Hold the two buttons down and go to the mode you want. 45-60 seconds max. Just make sure if it is something that you want to change often to mount the box where you can easily get to it.

Then there are electro/mechanical ways to lock out first for the 6-speed guys, and that is what I use. Description how to in the wiring sticky.

Roberts way is awesome if you always want to lock out first gear and have it be a true first gear only.

The gear lock out feature is a nice benifit if you are fighting traction issues. On our digital unit with built in TPS activation and gear lock out feature you can shut off and on the feature in a matter of seconds by pushing the push buttons and toggling through the set up mode.

I'm using an FJO mini-progressive, which can control 2 stages. I only have 1 kit, and it is grounded into BOTH stages ground "intercept" (which turns on and off the N20).

I have stage 1 set to be active with a 12-volt input on it's #2 input, and stage 2 to be turned off. Stage 1 is setup with a 1st gear lockout.

I have stage 2 set to be active with no 12-volt input, and stage 1 to be turned off. Stage 2 has NO 1st gear lockout.


This means, I have an extra switch on my Nitrous Outlet panel. I flip it on and it sends 12v to input 2, and turns ON Stage 1 and OFF Stage 2. If I don't turn it on, it sends nothing. This turns ON Stage 2 and OFF Stage 1.

Essentially, I'm turning on/off the 1st gear lockout with the switch. I have not read about anyone doing this, and only dreamed it up after reading about the 2 stages and what the inputs do on the controller. I'll be making a full writeup on my system when my few new parts come in from Nitrous Outlet.
