I had a question regarding lift-throttle behavior, specifically if anybody has found a way to influence it.

To see what I mean, cruise down the freeway, lay into full throttle for a second (don't really have to be going fast), look down at the shifter, then quickly lift off the gas. At least in my car, the shifter stays where it is for about half a second, then moves to the side, indicating the engine is now providing counter-torque. I'd like to see it move in sync with the pedal coming up off the floor.

That half second or so I believe is related to "rev hang" and a means of reducing NOx emissions caused by rapid throttle closure.

The problem for me is I autocross, and we often have to move the car through some rapid-fire elements which require coordination of steering and throttle. The delay in throttle response on lift, makes this much more difficult and inconsistent.

I'm fine with the way things go as the pedal is going down, but I'd like it to follow my movements on the way back up a lot better. Do these throttle maps influence this at all?

Thanks for reading, and in advance for the help!

Rev-hang is there for ease of shifting. Do you notice at what RPM it tends to shoot up or hangs for half a second? We can always experiment with the throttle map. We might not eliminate it , but we maybe can reduce it. That is why Wstar created this thread.
What RPM you normally find yourself having this delay issue? We can always tweak it!

Maybe try the Power Map and see if it lessens It.

or

ETC - "OFF" on Cipher.

j-rho 04-09-2015 11:56 AM

Sorry if this has been asked and answered - but does ETC off definitely fix this? And what else does it change about the way the car behaves in a performance setting? I figure I can have one map set with it off. In autocross we don't shift much if ever - we putt around in second gear. The throttle lifts I do could be anywhere from 3500 to 7500 rpm.

bleunetizen 04-09-2015 06:08 PM

ETC off is a global thing, you can't have it per map AFAIK. It will turn off synchro rev too if you care about it.

bleunetizen is right, ETC " Off " is Global setting, which means it will disable your ETC torque management setting in all your 5 Maps setting.

I can live without rev match if it means the throttles close when I lift. Only concern is what it will do to throttle application behavior.
Is it possible to wire up some kind of external switch for ESC?
Any feedback from anyone that has roadraced or autocrossed a 370 with it off?

It will be % ECU(throttle plate opening) = % Pedal travel. Might not be smooth enough , but how would you know without trying it?

ANMVQ 04-10-2015 07:41 AM

doesnt the ETC make the drive like cable throttle and not electric ? If so sign me up also.

I hope to have AWGD8's power map loaded in today and tested tomorrow AM when it not raining.

That is great!
It appears that majority of members here who tried ETC "OFF " did not work for them. I tried that on my Infiniti EX35 crossover and I hated it! It works on a Manual Tranny though....

Awgd8 04-11-2015 06:16 PM

Just would like to remind that Wstar Original Throttle MAP was designed for Autocross.
That is why he called his MAP Smooth/Linear. The reason why he created his is to make the throttle predicatable. If we put the cars power or response base from Low-Mid-high RPM the transition of power from each ranges is seemless. If I put it in number it is like this.

1 2 3 4 5 6 7 8 9 10

See the distance from each number? This is linear so the throttle can be controlled evenly without disturbing the suspensions balance.
So to compare Wstar vs my Map is unfair to him. I did not make my MAP for autocross, but for Drag race or more street tuned. If i have to put it in number it looks like this

1***2*3*4*5*6*7**8***9***10

I could tweak this a lot better and more precise if I can only have a G37 tune file to work with. My throttle maps came from EX35 crossover siimilar to VQ35HR engine. Some members says my throttle improved their car's response some did not feel a thing. As I said it again, I can be more precise if I can get hands of a G37 tune file that I can experiment. And if my MAP is being used for entertainement purpose and seems to be working for you. Pls. let me know so I can develop it further...

ANMVQ 04-13-2015 01:27 PM

Just ran the "power map" on my bolted G37x sedan over the weekend and relly liked it !
car pulled hard and the throttle seemed a bit more responsive.

Good to hear you like it! Is the pedal response subtle vs the stock or you could feel a big difference? The torque (at the right gear) should come at less than 1/3rd pedal push.

What RPM do you feel the pedal gets tighter(harder) where the torque seems to start? Another member with a 370z says his was at 2.2K RPM. But I think he tried AWGD8-MAP2 (On my previous post #297 page 20 ) PLs. See post below.

Now you just need to remove Etune password.... =)

That is great! I would like you to test

#3 first AWGD8-modified 2

Then

Awgd8-Power

Pls. let me know what you think? Also drive at least a few days so the car adjust first (tranny etc) then maybe the 2nd or 3day see if there are changes in throttle feel. I really need some feedback so I can make this better.

mag_black 04-23-2015 11:20 AM

Unfortunately, I only did DD and POWER from Post #373 http://www.the370z.com/3172041-post373.html

I'll be taking her on a long trip once she's back from the body shop.

I just tweaked my half throttle AFR (1/4-1/2 pedal push- @10-17 BFS/2,000-7kRPM) and made it to hit at 1:13.5 AFR or low 13's, and made a huge improvement to the pedal response.
Some times our tuners are more concentrating on WOT AFR and leave this lower BFS at 14.7 AFR. We do not care about gas mileage on POwer Map setting. =)

Keep in mind tweak your half throttle AFR for performance too! Preferably 1:13.5 AFR or low 13's and not 14.7 if you want power! (note: for NA engine only)

Awgd8 05-03-2015 06:12 PM

It appears that to feel the most response from my MAP , you have to drive an AT.

Awgd8 05-05-2015 06:09 PM

Done!

ANMVQ 05-06-2015 07:00 AM

Is this something I have to ask my tuner about ? I have to send some logs over to my tuner this weekend, Z1 mani and ported lower intake and would like to add this in also. I'm on the the POWER map now. BTW like it! out ran a S4, X6( Twin Turbo+ I had 2 people in the car) and Mustang GT :)

You still have the aggressive Power MAP , nothing has changed. If only your Etune is not password protected, I can tweak your stock throttle Map and change it to feel like the Power Map. This is basically a custom throttle table Map specific to your car.

I am working with one of the members here, but he has a 370Z 6 speed Manual.
I gave him all my throttle tables to test. I also made a custom (came from his stock throttle table) and designed it to have an aggressive throttle table specific to his car. The most responsive throttle feel is actually the ETC Off for Manual tranny, but he likes to have traction control so I made him an aggressive map off his stock throttle table.

Sorry, I did not answer your question, yes! You have to tell your tuner to give you an aggressive performance map even half throttle. He can tweak your target fuel and adjust fuel comp to be more on the rich AFR side (13.5 on half throttle) instead of 14.7

I did feel the difference just by changing this area of the map.

firulice 05-06-2015 10:51 PM

Let me know when you get a great one for the manual tranny and I'll have seymore update mine

Awgd8 05-07-2015 04:52 AM

Firulice, I have one that you can try. Pm me your email.

Awgd8 05-07-2015 08:58 AM

Hi guys, I decided to remove my Throttle Map table here. I prefer to just PM me so I can tailor what kind of response you want from your stock throttle tAble. this way, the throttle table you have is specific to your car.

Awgd8 05-10-2015 03:13 PM

Does anyone has an open Etune file for G37 sedan 7 speed AT? I would like to make a specific throttle Map for this car.

It appears that the G37's throttle table is exactly similar to the 370z.

ANMVQ 05-19-2015 07:55 AM

Hey , Been drive a week or so on that new throttle map, Feels pretty good, I had a small flat spot after shifting no its gone, RPMS just keep swelling up :)

That is good to know! I modified it from the G37/370z stock throttle table.

T-Rex57 02-08-2016 04:32 AM

Hey guys,

Sorry to bump this thread, but I have a 7AT (Australian car). I've had it tuned with Uprev, but the shifts are quite sluggish, especially at town speeds. Sometimes if I jump on the car there is (what feels like) a few seconds delay before anything happens. Mechanically the car is fine.

If I wanted to modify the tune myself (or learn how to) with the info in this thread, is that possible? What would I need to do make this happen?

You need a tuner version cable, and a copy of your tune. I will PM you

Kabestro 03-11-2016 09:02 AM

Quick question, seems I over oil my K&Ns and my MAFs act up alot. I'm switching to AEM dry filters and since I've sprayed my MAFs so much with cleaner, I bought new MAF sensors. Would I need to fine tune my tune because of the new MAFs?

V1H 03-11-2016 09:11 AM

I cant advise on the MAF retune but i also use AEM Dryflow Air filters on my Stillen G3 intakes. I recommend them

I don't think so. Just do the ecu reset procedure to clear the fuel trims.

If you have Uprev you could've datalogged the MAF sensors and compare the pair then replace and compare the new pair. Ideally, both should read very close to each other

I haven't done the change yet, so I think I'll do the data logs. Thanks!

ANMVQ 03-17-2016 02:22 PM

Take the mafs out and clean them also, you probaly have oil on them. ONLY use CRC MAF cleaner

Awgd8 12-26-2017 12:03 PM

Hi Guys, I’m getting a few email regrading sending the tweak Throttle response.
Unfortunately, I no longer have an Uprev and I switched to Ecutek.

I believe I deleted all my UPREV FILES, but I’ll have to check one more Backup disk that I know I kept somewhere. If I do, I will gladly post the throttle tables here for you guys to use at your own risk.

Cross your finger.

Awgd8 12-26-2017 02:28 PM

You have to have an Uprev Tuner license to copy and paste this to your Uprev tune file on throttle table setting.

or

Have your tuner copy and paste this to the throttle table of your Uprev tune file.
