Hey folks!

2010 Maxima 3.5SV's do NOT limit throttle on take-off as everyone seems to think it does to "protect the CVT". I'm sitting at 145,000 miles, stock except for y-pipe.

Below two video links represent 2 WOT runs per video. Sorry about the length, but people around this area of the country do everything in their power to ensure that you get nowhere fast. I did not turn off traction control at any point during these runs and you can occasionally see a little blip from 88% throttle (which is how these vehicles read out WOT) down to around 66% and back to 88. That would be traction control kicking in due to some minor wheelspin. The last run on video 2 is the best and is definitive proof that these vehicles DO NOT cut your throttle off-the line. Well - in my opinion, all 4 runs prove that Maximas (or at least my Maxima, which I assume is like any other) do not limit the throttle in any way, shape or form at any speed (except 85mph and up). It might dial back throttle if it detects wheelspin which you can see in the first 3 runs, but even on the last run that still had some minor wheelspin, it doesn't cut or limit throttle at all. It's pretty plain and simple - if you floor the accelerator pedal, the throttle body does immediately go to WOT from a stop.

I don't have the software to edit the videos and display text in the video itself, but you can look and it's pretty self explanatory. I logged RPM, speed, "A THR2" is absolute throttle position (which represents what the throttle body is doing) and "PedalD" is the accelerator pedal position (which represents what my foot is doing).

Observe that when PedalD goes to 95ish % that A THR2 immediately follows to 88% (representing WOT) immediately on take-off. No throttle limitation and there is no delay in the throttle hitting 88%. It may dial back throttle if TCS senses wheelspin, but it's minor an brief. I don't plan to check with TCS off because I like my tires and the TCS on these cars is pretty unobtrusive.

I have confirmed that it DOES dial back throttle to 44% at 85mph several months ago. I don't plan to do that again because that's not up for debate and I have no desire to go that fast. I just want people to stop saying that these cars limit throttle on take-off to protect the CVT because they don't. It's misinformation.

If someone has proof otherwise, I"d love to see it. I searched the forum and couldn't find anything other than subjective statements and 2nd hand information. Therefore, I decided to find out for myself and share what I learned. I've seen several mentions about Ghozt having UpRev remove the throttle limitation. I'd like to know more about that, but couldn't find anything specific on the forum about it.

 

This may be so, but the car seems like it has some sort of delay when you punch it from a dead stop. I drove my son's 5th gen (2002 SE) the other day....that car takes off very quickly from a dead stop. That car is still a lot of fun to drive.

 

Ive never noticed that. These Maximas may FEEL slower off the line than previous generations, but I would be willing to bet that if you lined them up or took them to a dragstrip, they would be about equal. Mine has enough power to spin the tires up to about 25mph with excellent tires in warm weather on clean asphalt. Maybe the 2002's had a better suspension and could lay the power down better. Dunno.

 

LOL-----------------

Throttle response that is delayed from ETC or better known as Drive-by-wire throttle.

Ill believe Ghozt and a few others that have done it themselves, thanks though

 

You used an app to get this info? If so I need to lol this dead horse have been slaughtered to many times. There are write ups/discussions/arguments, use the search to get you're answer.

 

You should do your own homework. I have done mine on the forum. The latest post including reply from UpRev was that the earlier G's and Z's DID limit throttle on take-off. However, UpRev suspected that the Maximas did not and suggested logging speed, accelerator position sensor and throttle position sensor during a WOT take-off from 0mph and then overlaying the TPS and accel position sensor. I did that in above videos. Torque management on these vehicles is confined to the transmission (if there is any) and NOT the throttle.

Accelerator pedal position (what my right foot is doing) and throttle position (what the throttle is doing) mirror each other.

Are you saying that Nissan is non-compliant with OBD-II standards and mis-represents OBD-II data? If so, then you have a huge federal lawsuit on your hands and stand to win lots of money. Go for it, bro. LOL.

And also - do your research on Torque Pro - one of the best if not THE best app for OBD-II data loggers. We're not looking at Nissan-enhanced data. This is just plain old OBD-II generic data that any 1996 and later vehicle would provide. This technology has been around for 19 years...

 

I did it myself but...eh...whatever. LOL....ha! You fingered it out. Nissan's OBD-II data is all lies. The coolant isn't 200 degrees, it's 100. The RPM isn't 3000, it's 1000. Dude...look at the videos. Unless Nissan is arbitrarily deciding to falsify OBD-II read-outs, then yes...if accel pedal is pressed to floor then the throttle immediately goes wide-open. How can you say otherwise? I've done my homework.

You have PROOF staring you right in the face that there is no throttle delay, but you're still saying that it exists??

 

::thumbs up:: not gonna debate this with u and you're free app.

 

It's not a free app. It's a paid app. Again....do your homework. Might wanna read up on OBD-II PIDs also. The app simply asks the cars ECM "what is coolant temp" or "what is RPM?" or "what is the throttle position?". Doesn't matter what app you use...be it free or paid or the $400 AutoEnginuity software package I bought a few years ago. All these apps do is query the ECM requesting a response...regardless of how expensive or cheap or free the app. It is honestly basic mathematics (add, subtract, multiply, divide) and knowhow to convert hexadecimal into decimal.

 

Was thinking the same thing...................

 

Have you ever driven a 5.5?


There is no way a 2012 SV space boat is going to touch a 5.5 in a straight up drag race. Throttle limitation or no. Stop spreading MISINFORMATION about the 5/5.5 gen lol.

Maybe take the thing to a dyno & attempt to.....oh right I forgot. CVT wont let you hold a "gear".

That sucks man. CVT sucks. Period.

Its not your fault. I blame Renault for the lack of a true 4DSC since 2003.


Infinity has a few good models but not Nissan. Everything they've produced since 2003 pretty much sucks.


Thanks Renault for killing the 4DSC.

 

Not spreading MISINFORMATION. Saying "I would be willing to bet" and "about equal", people with common sense have the understanding that it is an OPINION. I am not stating anything as FACT. You should be out with your 5th Gen whooping up on some Lambos and Ferraris instead of wasting your time on the forums here.

And what does a dyno prove? Nothing other than how many bhp you're pumping out. Who gives a crap. Laying the power down to pavement is what matters. The only thing a dyno is good for is bragging rights and tuning. Tuning is good. Go go racer boys like to brag about how many hp their souped up ride is pushing, but it doesn't say much about how fast the car is.

 

You are right. I am defeated. Give up I shall. Taking the time to provide proof to anyone on here is useless. I messed up. The 9th Gen is a slow old grandpappy car. Done.

 

Sorry to bump an old thread.
May I ask OP or anyone what PID shown in the video of A THR2 and PedalD? what are the full entry names of these 2 values in torque pro?
Thanks
