What possibly can make this happened ?

Do you have the 2300 map loaded with the last row (number 16) with the stock values in it?

You getting any check engine lights,and when you first drive it ,it's ok but the pedal seems to fade away.

I'm starting to think it may have something to do with the throttle bodys,did you disconnect them at all and did you do the throttle body relearn steps?

yes i did disconnect them when i installed the s\c


no i didn't do the throttle body relearn steps

how do i do it ?

Do I need to do both steps or its enough to do one of them ?
And will it not harm the current ECU program ?

The ECU reset is basicly just disconnecting the battery for like 5-10 min

so disconnect the battery as above then do the 2nd one.

All programs are not disturbed.

You can no longer edit the 7200 rpm line.

wstar 08-30-2013 06:10 PM

Heh. I guess they should make up their minds! FWIW, the only time I saw the 7200 line in mine (when I was reflashing in July I think?), I just copied my 6800 line to the 7200 line and that seemed to work sanely (on that Curve2300 map I'm still running). I wonder if I should reflash the stock 7200-line data before I do a software update, in case by "removing" the 7200 line from the tool, they're leaving my old custom settings stuck in place?

Baer383 08-30-2013 06:22 PM

Hans told me to put the 7200 rpm line back to stock value,and I haven't had the same issue show up.

unknowndesi 08-31-2013 02:18 PM

Wow you're right I made a back up of the original rim editor and supporting files and updated it. I wonder why they went back to the 6800 line

Just thought I'd tell you my findings.

See my quote above for the answer.:hello:

Awgd8 09-27-2013 06:40 PM

HI guys! I am new here. I do not have a 370z, but I have a crossover 2008 Infiniti EX35, which is now called Infiniti QX50. I believe I am the only guy with UpRev tuned EX35 and Seymore4 did my E-tuning a few weeks ago. It is NA Engine -VQ35HR AWD 5SPEED A/T dual intake.

I have a Uprev tuner's version and I could play around with the tune 24/7 =)
Basically, I only requested 3 MAPS,
1)TUNED WOT-Rich 12.9:1 for Winter
2)Valet
3)Tuned-WOT-Lean (fuel economy) 13.25:1

So I got bored and read this forum. I decided to copy all parameters from my MAP1 except the Electronic Throttle one. I copy what WSTAR made on his throttle parameters and I noticed a much better improvement from 2.5K up RPM. I could definitely see an improvement in smoothness and throttle response specially on the highway.


NEW MAP#5 DONE!

http://i39.tinypic.com/2h33igk.jpg

Thumbs up to WSTAR ! I enjoy using my new MAP4 with Wstar throttle settings when I drive on the highway. Is this WSTAR final ELEC. Throttle Settings?

BTW, even though ECU ROM on CIPHER shows 6400 RPM MAX vs 6800 and 7200, the settings still works for my car~

UNKNOWNDESI, What about your parameters? Is yours final too? I will give that throttle parameters a try too and I will report back.
That will go to my MAP#5.

Baer383 09-27-2013 09:32 PM

Your not suppose to change 6800-7200 rpm,you just leave the stock values if not the ECU will throw it into limp mode at high RPM.

Thanks again for posting your throttle settings here. I will give your setup a try later today. If you can see above, my Cipher RPM for Elec. Throttle is only up to
6400 RPM. The rest are up to 7200 RPM (fuel map etc)

wstar 09-28-2013 08:51 AM

Not that it matters now since the 7200 line is gone in the new version, but I should note that yes mine threw a P0605 eventually. I just hadn't actually hit the rev limiter with that map in place. Once I did, boy that was unpleasant :) Car limps until you reset the code, something about a ROM Error.

Awgd8 09-28-2013 03:15 PM

Ok I just tried both settings from baer383 and wstar and I could hardly tell the difference. I just noticed I have slight rough downshift while cruising with baer383 settings. It id only once in a while, not all the time.

wstar 09-29-2013 06:45 AM

The differences are subtle. Also, as noted earlier in this thread: I think the general improvements are good with these maps (in that they allow WOT at low RPM with a bit less lag, and they do it with a smooth function instead of a herky-jerky step function), but I think the curves are backwards from where they should be for drivability. I just haven't had the time or inclination to go and come up with another version of this.

By the way, have you compared your stock map with the copy of my stock map I posted? I don't know how close they are to begin with.

wstar 09-29-2013 06:51 AM

I don't think I posted this here before, only off in another thread, but this is what I mean. This is a scan from the excellent book "Think Fast" that covers a lot of race car setup stuff. They're making the case that it's better for the curve to go in the opposite direction of the one in my throttle table. Either way you want the start and end points the same, so the curvature of the graph is all about trading off fine control in one area for lack of fine control (rapid response to input) in another, and the argument is basically that you want more fine control in the low end of the pedal since that's where you're feathering around with traction in mid-corner:

Well, with that in mind, are you interested in developing a table with that curve?

I could help with testing.

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.

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...

http://i44.tinypic.com/2vijjgw.jpg

http://i43.tinypic.com/jhpxdy.jpg

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... =)

wstar 09-30-2013 10:17 PM

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...

Awgd8 10-01-2013 05:20 AM

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!

wstar 10-01-2013 10:26 PM

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 :)

Sh0velMan 10-12-2013 04:56 PM

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.

������

Riptide67 10-17-2013 10:25 PM

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!

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