So I've gone through a bunch of threads but this hasn't come up. I really, really want the WOT gone on my 2012 sl. Is there a way to do this or am I going to have to suck it up and buy a tuner?

The only way I know is with a tuner or one of the superchips, but if there is another way I would love to know also.

Are you sure you have the restriction? I have a 2011 SV 4.0L, and using the Torque app with a bluetooth dongle shows the same full throttle percentage all the way from 0 mph up. I had heard that Nissan got rid of the restriction at some point, but didn't see solid information on when, however my 2011 doesn't seem to have it.

I can't tell if my 2012 has it or not - so I tend to believe I don't.

2013 was the year it was removed from the factory. Only way I've ever heard to remove it on previous years is a tuner or an UpRev tune.

I'm pretty sure it has it. I can punch it and no matter what I don't get real power until after 20mph.

My 2012 was restricted.

Now it's not. You need a tuner to do it, or someone with the factory Nissan flash software.

Now the real question. Does anyone know someone in Las Vegas that can do this?

I have a '13 2WD & Im pretty sure I have the WOT restriction. I can nail it from a stand-still & the power doesn't really come on till I hit somewhere around 20-40 mph. I also run Torque Pro & I have it set to see the percentage open of the butterfly valve in the throttle body rather than the percentage down that I'm pushing on the skinny pedal. Although I havn't logged it, the widest it shows the butterfly valve being open is 89.4%. Now, Im not sure if that would be considered "WOT" or not, buuut seeing how it doesn't show it to be 100%, I'd have to go with, no.

Roughly 90% on the tps is WOT.

I don't know, bdhaeh. I mean 10% left for the butterfly to open is quite abit. Don't ya think? After I first start my truck & its still in 'warm up' mode Torque shows the valve to be open roughly 5%-6%. Once the engine is up to temp it settles out right at 3%, give or take a few tenths of a percent. So, IMO, another 10% should be a pretty noticeable difference. I'm not saying you're not correct, Im just throwing my thoughts into the ring to see what you or others have to say about it is all.

One thing I do know is that when I lay into it from a dead stop it feels rather sluggish till somewhere between 20mph & 40mph. Once it hits some predetermined mark it comes alive. Its almost as if I have turbo lag.

Ill do this as well, but if anyone else is running Torque or a similar app, see if you can catch what it shows from zero to 20mph & then maybe a zero to 40mph run. Or at least the percentage open of the throttle valve before it 'wakes up'.

Is the Throttle Position Sensor reading the % that the accelerator pedal is depressed, or the actual % of 'butterfly' w/in the throttlebody?

If youre asking about what it shows on the Torque app, it has several sensors to choose from, such as accelerator sensor A, B, C, etc. Certain sensors have a blue question mark off to the right of them that further explains what information that sensor is showing. I cant remember which sensor I picked, but it's supposed to be the one that shows the percentage the butterfly valve in the throttle body is open, not the pedal itself in relation to how far down I'm depressing it.

i have a 2007 nismo. i live in california and have a cortex superchip installed with volant CAI and flowmaster muffler. with that combo throttle response is instantanious when you get on the gas. problem is i have to revert to factory programming to get smog'd every 2 yrs. come to find out hypertech sells CARB approved programmer (Max Energy) that will pass smog, EO: D-260-15. do your smog guy a favor and keep a copy in your glove box.

I tuned back to stock to check it and my gas mileage which is terrible tuned and not.

Stock at idle my tps reads 1%. Punch it and it jumps to 80% then immediately comes back down to 60% then jumps back to 80% after 40 mph.

Tuned it stays at 80%.

This is from the data logging from my cortex.

Huh. That's pretty interesting stuff right there. I keep forgetting about logging the tps to see what its doing & when. Im definitely gonna have to remember to set my Torque app up to log the tps, rpm, speed, & maybe one or two other things & see what it shows.

If anyone else has the Torque app or something similar, try logging the tps plus a few other sensors then we'll all report back & compare our findings. Even if anyone has a Bullydog, Super-chips, etc. tuner & can log sensors, I'd be curious to see what it shows with the tune 'on' & 'off'.

'13 and up no longer have the restriction from the factory. My '06 and my '11 both had it, my '14 does not.
With the BDGT, once the restriction was removed I got 100% TPS angle from idle at full accel on both previous rigs so not sure why you guys are only seeing 80%.
As described above, if you still have the restriction, you will only see 60-70% throttle until you reach 40mph. It's a noticeable jump at 40 mph if you put it in manual 2nd and just stomp on it.
With the BD gauge set up to read TPS angle mine reads live TPS%. It goes to full throttle (100% TPS angle) from a stop when I put it on the floor. Maybe there's a different set of programming parameters on the Superchips tuner and TorqPro app that explains why you're only seeing 80%??

Now the real question. Does anyone know someone in Las Vegas that can do this?

There is a shop here in Vegas that does Uprev but I can't remember what it's called. You can always order a Bully Dog tuner or something equivalent from Superchips etc..

Fair to say your '14 felt a bit more responsive in stock form when compared to your '06 & '11?

By manual 2nd, do you mean auto trans in 2nd? If so, will it come off the line in 2nd? I'm 6-sp manual, so IDK.
