Like the title says i can't accelerate past ONLY ever has this happened after installing the N2MB 2 feature 2 step WOT box... The 2 step works with clutch depressed but even in neutral no clutch in it will not rev past 4k rpm... even in gear. Its like there is a perminant 2 step at 4k almost... Ive tried searching but can't find anything about this. If anyone can tell me how to fix this it would be great.

i bought it used, how do you power it off?

i can't get it to connect to a computer either
Remove the power or ground. I don't think holding the button will power it down

The WOT box comes preset to 4000rpm 2 step limit. It seems to be actuating even with the clutch not depressed. Perform these steps to ensure it is connected properly:

Testing the WOT Box
1. Key on the car but do not start the engine. Press the gas pedal to the floor. You should see the LED on the WOT Box start to rapidly blink. If it does not, check your APP sensor signal connection (WOT Box BLUE wire).
2. Next, with the gas pedal still depressed, press the clutch pedal to the floor. You should see the LED on the WOT Box briefly go out, and then come back on solid for one second and then finally resume blinking rapidly. If you do not see this, check your Clutch Pedal Position Switch signal connection (WOT Box GREEN wire).
3. Next, start the engine. Quickly press the gas pedal to the floor and immediately step on the clutch. You should hear the engine start to rev up, stumble for a short period while the ignition is cut, then return back on and continue revving. Remove your foot from the gas before you hit the rev limiter. The 2-step will not engage if the gas is depressed before the clutch. This is normal. If the engine does not stumble or pause when the LED turns out, then check the RED/BLACK paired wire. Verify that the RED and BLACK 16 AWG wires are wired facing the proper way. If they are reversed, the ignition cut will not work.
4. Lastly, test the 2-Step. Press the clutch pedal down and then quickly press the gas pedal all the way down. The gas pedal must be floored for the 2-step to engage. The engine should rev up to the desired RPM and hold. If it does not, be sure to remove your foot from the gas before you hit the rev limiter. If the 2-step does not work, check the WOT Box YELLOW wire.

Obviously you haven't done all that because the test I posted requires the engine to rev PAST the 2 step rev limit but you're saying it won't. Re-read step 3.

It seems like the 2 step is alwas engaged which probably means a clutch switch issue like under said.
No it goes past the set 2 step... it doesnt go past 4k rpm's... i have the 2 step set at like 3400

If you two step it does it hold 3400? If it holds 3400 but goes past it with the clutch up then the switch is probably good. The only two causes I can really see at that point would be a bad wot box or a problem somewhere else on the car unrelated to the wot box.

If it does hold 3400 but hits a secont limit at 4000 with the clutch up, I would bypass the box and see if the problem goes away. Cut the red and black wires spliced into the engine harness at the c101 connector next to the brake booster. Then connect them together, on the engine harness side, not the wot box side. See if the problem goes away and report back.
