I will post my stock throttle map vs your stock throttle map later.

So far, I am using your throttle settings. Syemore4 (UpRev pro and E-tuner) setup my tuned throttle Map. His setting is a lot smoother, but yours has early pedal pull. Less than 1/4 pedal push at 2.3K RPM in D mode (I drive 99% manual mode) the response is there. Seymore throttle response starts at 2.7-2.8 K RPM. Once I pass 1/4 pedal travel, responsiveness starts.


So I find yours as my DD settings. It is really good!

I just posted my stock throttle vs wstar stock throttle settings. Still pending approval. What the !$@ kvk!

I will someday. Setting up the software to do it as a one-off and doing all the street testing of the map is a time consuming PITA, and I've just got bigger things to worry about right now than fine-tuning the throttle (like, wiring up my new dash/steering controls and getting the cage-related stuff done). Maybe in November when all that settles down.

How long does it take for the moderator to approve the picture i posted yesterday morning?

Smooth Throttle for UpRev
 

Whoops. Wrong thread.

I am reposting this again. It sucks to post picture here, bec. it takes forever for the moderator to approve it.

The last MAP is the best throttle MAP I have used so far.

Well, your stock map is quite different from mine. That the modified one works for you is probably mostly a matter of luck :)

I assumed that my VQ35HR engine has the same diameter throttle bodies and sensors found in the 370z. I heard that my stock car ECU was detuned from the G35/350z stock ECu.
Nissan made my car less responsive (smoother) to accomodate female buyers.

Here is my car's engine...

It has that stock HR intake manifold (Motordyne M370 that G37 crowd wants!)


Tested it again on a 65 degrees ambient temp. perfect throttle for me!

I am just curious with those - negative numbers. What if we just change it all to positive numbers? You know? flip the same - numbers to positive? Hmm, i might have to try that this weekend... =)

I really don't know what the numbers mean, so I couldn't tell you for sure about the significance of negative values. I think just flipping the sign on them is probably a bad idea, as that would be a big jump in value. I know it's nothing as simple as "values below zero cut fuel/spark and go into engine braking", because we can easily get engine braking at deeper pedal positions than the chart goes negative for at high RPMs, e.g. if you play around with the pedal while sitting at say 5-6K rpm in 2nd or 3rd.

Keep in mind that in my original experiments, I didn't have to move all that far away from factory values to get very ugly behaviors that weren't drivable *at all*. Experiments are at your own risk, and scary things can happen. Some of the odd behaviors I remember from testing maps that were just a little too much out of range or out of shape in various areas include things like:

1) The accel pedal seeming to act normal for the first 15-20% of pedal range, and then you move it a hair further and the car suddenly leaps into full throttle out of nowhere, scaring the **** out of you and breaking traction.
2) The pedal seeming to act normal to nearly full throttle, but then when you hit full throttle the car acts like it's past a rev limiter (when it isn't) and cuts fuel/spark dramatically, shocking the drivetrain if you were in the midst of acceleration or shifting.
3) The pedal seems extremely unresponsive for the first half or so, so you keep pushing your foot down, then it suddenly responds out of nowhere and floors the engine..
etc...

Be sure you're on a wide open road clear of traffic if you experiment with crazy values in this table...

Seymore4 sent me 3 throttle test map during my e-tuning. There was one setting that when i past 3/4 of the pedal being push down, the car does not want to pull anymore or harder to pull. ( kind of an -engine breaking acting against the forward momentum)

Right now, I am using your modified map for a week now and the longer i drive the car, the better the throttle response gets.

This morning it was 62 degrees F and throttle is a lot better
than a few days ago. When i left work today, it was 82 degrees F and still responsive. When I say responsive, the car moves forward just a small tap of the accelerator ,not a fast tap, but you plant your foot on the accelerator and less than 1/4 pedal press the car moves right away. I also noticed during high speed freeway acceleration, at 65 MPH + the pedal tightens a bit at close to half pedal push and just a small press of the accelerator the cars pulls a bit more. Also while cruising at that speed and tried to accelerate to 80 MPH, it smoothly pulls harder, it is like the car has more power to give... i decided to floor it from 60 to 80MPG on 4th gear (my car's tranny 1:1 gear ratio) and I did not feel a rough or abrupt surge, but a smooth pull at WOT!
The downshifting is also smooth at that speed from 80 to 60MPG. I did not feel any abrupt deceleration or strong engine breaking at all. Whatever you did to the settings, it was perfect for my car!

I have to thank Seymore4 also, since he did my A/F and timing settings. I did change my fan control settings also, so the engine runs cooler so heat does not grab the cars power.
I guess i will keep your setting as is ( wstar)

Thanks man!

Well, glad it's working for you, although I'm still kinda shocked it does at all. I guess shape is probably more important than absolute value, within small reasonable margins :)

Used the 2300 table in an Autocross today. It was a fast course with some high speed sweepers (~50-90mph) and this throttle table worked perfectly. It was so, so much better than the stock table.

������

I sent this link to my tuner for him to look through. I'd like to have the 2300 map done as well. Seems like those using it are loving it compared to stock!

How do u copy those values on page 1 into Uprev?

Highlight it and copy, then go over to your throttle table in the rom editor and paste
