:rofl2: So, there is no way they can give your the code for your tune? Though, might not be a good idea, but tell them you waive their responsibility if your car goes kaboom! =) Kidding aside, it is only the throttle you are playing with. I changed my throttle MAP so many times and flashed my car maybe close to 40x or more and never had a single issue. I just let Seymore4 do my fuel ratio and sometimes when summer or winter comes, I add or lessen the fuel table on the high load /WOT (wide open throttle / pedal 2 d metal) rpm side of the table. I noticed that when season change, my Summer WOT AFR is spot on at 12.8- 12.9:1 but gets lean at 13.6- 13.9:1 on WOT during Winter time . Winter season has denser / cooler air = more air , you add more fuel so it does not run lean. Summer time , thin air /warm = less air you lessen the fuel so it wont run too rich. If I tune my car on winter, I have to lean out (lower fuel) table during summer to get the same 12.8-12.9:1 WOT AFR of the winter tune. I heard some techs says it does not matter since the ECu will adjust, but I did experiment it for 2 winter/fall and 2 summers by data logging my runs.. It does change the WOT AFR with winter and summer season
That is the reason why I have this Uprev Map setting like this below.

MAP1 : Performance Summer My throttle Awgd8 Blend 12.8-9 WOT
MAP2 : Valet mode 3K RPM max.
MAP3 : Fuel Economy (seymore4 tuned) with stock EX35 throttle.
MAP4 : Performance Summer wstar throttle.
MAP5 : Performance Winter Wstar throttle 12.8-9 WOT

I am not sure if also the winter fuel vs the summer fuel has significant impact on Performance too!

You will definitely feel a big difference on how the throttle react on just my AWGD8 Map 1. You only have to press the pedal at 1/4 throttle and it goes right away. I cannot imagine using my MAP with a close gearing ratio like the G37. Maybe just use the D or DS mode for smoother acceleration from the dig.
Though, MAP Awgd8 # 1 is very close to wstar Map, it just that you only have to press it less or around 1/4 pedal push to feel the torque or responsiveness. It is instant once you push at 2K RPM at the right gear.

I wish someone test my MAP and see how it feels. So far I might have to remove the Map AWGD8 # 3 since it is too aggressive on the lowend and strained a bit towards the midrange ( on my car ) Maybe yours is different. I highly recommend testing my AWGD8 MAPs. # 2 and # Blend 2/3.

So far one member (merkil) commented on my Awgd MAP # 1 post # 276

i see that you figured out the same thing i did... that basically, you really wanna tailor the throttle curve around the individual low speed and cruising operating band so that you find the perfect mix of driveability and response. my g35 is geared more aggressively, even with a much larger tire than my 370... thus my threshold is a little higher. i cant wait to try your map out on my car and see how it feels. i get that lag and that lazy *** clutch response fixed and ill be much happier with my car!

Hi guys! I just want to verify your G37 1:1 gear ratio (4th gear?) and see how does the RPM tach behave at 60MPH and floor it .... Does it kind of shoot up from less than 3K and stays in 3K while your gunning it and sloooowly creeps above 3K RPM ? Or does the tach shoot up above 3K RPM right away like how the 3rd gear behaves....?

Also, lets say you red line in 3rd gear and shift to 4th, how low does the RPM dropped after shifting to 4th gear? Or whatever 1:1 gear ratio you have in the car.

I like to verify this bec. I did try to merged in the highway this morning and floored it in 3rd gear and when I shift at 4th, the car is pulling , but my tach kind of stay longer in 3K RPM and very slow to rev up above 3K as it pulls or gain speed. I do not remember this instances since I hardly floor or gun my throttle on 4th. MY car has 5 A/T tranny so 4th is my 1:1 gear ratio. 1st, 2nd and 3rd gear Tachometer bounces up quickly like a horny rabbit, but 4th seems slower...

whats is the stall speed on your converter? it sounds like your transmission was slipping up until stall speed like its supposed to... until you got enough speed to lock up in that gear. when you did your revs started climbing with respect to your speed again. prior to that your speed was climbing but your rpm was holding constant (indicating slippage). that said, thats perhaps slightly more relative to the older domestic automatics that i actually have experience with. modern transmissions with electronic control units really are designed to vary the line pressure to smooth a lot of that out. perhaps what has happened was that in all this throttle and vvel tuning, your base fuel schedule for a given rpm range has increased/decreased due to running a larger/smaller cam profile at that speed and therefore requiring more/ess fuel. this means that the value plugged into your calculated load map is now off and that can affect transmission performance. log your calculated load and base fuel schedule and make sure thats not off anywhere... especially in that 3k range where you are experiencing the slip. if all that checks out id say that your converter is just slipping, as intended, to allow the engine to get up into its powerband. the only reason u notice it in 1:1 and not the other gears is because its a long gear. in the lower gears you probably accelerate past that point of slippage quicker and dont even notice it.

What exactly do those tables seem to do?

im not sure whether im dull as sh1t but i could not feel any difference to any of those throttle maps posted.. what does it really improve? response? or is it mainly for auto transmission cars?

However I liked the ETC off. Wonder if uprev can have it moved to a selected map rather than global setting so we can get a choice of turning it on or off on the fly..

Probably the easiest way would be to have identical ROM's loaded for map 1 and 2, with the only difference being ETC on for one and off for the other.

Then switching is just a matter of using the cruise control buttons :)

Can you do that per map? I was under the impression that it was global. I remember talking to Omar about it and he told me that you would get no throttle at all without ETC enabled. I asked him to disable it so that the throttle control would be more like 1:1, but he said that it didn't work that way. I hope he was wrong and that does work for this application, but that would be a bit frightening if he would make a mistake like that AND he has been tuning my car for quite some time now.

Yes,, but still cant tell the difference haha

turning ETC off was nice though. I think I will bring my laptop to the track or something so I can turn the ETC off while im there.. cuz I want the cruise control for the 3hr drive each way to/from the track.. haha :driving:

You can disable the ETC and the car will drive just fine.. and yes I also do believe that it is global, hope either the throttle map can be modified to have same effiect or have it disabled per map..

Cool!

Now I remember why I didn't go through with it. No cruise control...........I could care less about SRM, but I am kinda weary about giving cruise control up. None of my S13s had it. Come to think of it, none of my other cars had it except the Tahoe.

Ah, mmmmm... Looking at your car's list on your profile, I wonder why? The EX35 is like a Honda Del Sol performance wise... :roflpuke2:

I'm pretty sure ETC can be on or off for separate maps -- easy to test.

Note: Okay to turn off for MT, but not so good for AT. Seems to put more strain on the trans during shifts.

:iagree: Not good for AT , did that last year and it sucked!

it is under "settings".. and not under throttle menu :(

Good to know about the ATs. Maybe that is why Omar was quick to say that it was a nogo. My maps are locked from UPREV anyway AND I am no where near my car to test the theory.

Oh, crap -- that's right.

Never mind...

global ETC off
 

I've also been told by Mark@Abbey Motorsport (UK) that ECT off cannot be done for one map only but is a global setting.
I wish it wasn't true

I have a Tuner version and yes it is true! It is one for all Map setting.

If you want it off, just PM me I can do it for free! Pretty easy to change it as long as the MAP is not locked.

Maybe this will help explain driving force values

After trying all the maps except the Awgd8 blend 2/3 map (thought i loaded it but i didnt), here is my feedback. Bear in mind that this is my daily car, 6MT and i drive pretty sedately but like to make sure the Z gets some respect at the lights.

wstar smooth throttle: Improvement over stock, too smooth for my likings. For those who have followed my lengthy random loss of throttle response posts, i think this map is the cause of all my grief and pointless searching. No discredit to wstar at all, but after switching for the Awgd8 maps i've clocked 1200 faultless kilometres. It was very weird because i ran the wstar map for ages then all of a sudden the throttle started acting up and required a restart to cure. It got so bad that even a few minutes after a restart it would act up. Then it became every time i drove more than 20mins. It went to the dealer, they couldnt find anything but it didnt come back for almost 2 weeks then it came back. Then it became really random. Anyway, i'm glad to be enjoying my Z again.

Awgd8 v1: Improvement over wstar's map, more pokey but it made me crave more.
Awgd8 v2: This is my favourite. It rips hard from 2200rpm upwards. Screams by 3000rpm and really wakes up the intakes and exhaust.
Awgd8 v3: Similar to Awgd8 v1 in normal street driving. Pretty strong and keen from mid to high rpm. But the low rpm range of this map just doesnt have the punch of v2. I will load the blend map in a few minutes and give it a run.

Thanks to everyone for their contributions to thia valuable thread!

So how many of you are using this modified mapping?

That's potentially quite useful, but a lot of math.

Are there any calculators that might make it easier to apply those ideas to the uprev tables?

I guess one could be made in excel...?

I have been using my MAP 2/3 blend for a while now. I specifically created those AWGD8 maps for my 5 speed A/T 2008 EX35 VQ35HR crossover. Some members here used the map I made, but it could only be felt the difference on the Auto tranny. For Manual tranny, the majority feel the best improvement if they just turn off the Electronic throttle Map setting via Uprev.

I am surprised that it worked out for the manual. Did you try turning off the Electronic throttle control via uprev? I heard this is way better performance if your car is Manual. So basically, when you turn it off, you are not using any of our Throttle Mapping, but direct 1:1 from pedal position and throttle opening...

after trying them all, i still like map 3 the most. it has a bigger pickup and kick in the rev range i usually drive in (up to 3200ish rpm). i'm going to have to learn how to create my own map. I am aware of the ETC off mode but i like the electronic aids (traction control and cruise control, SRM)

I remember I made Map 3 for more low end torque and midrange power, but for my car, it seems like the top end flats out a bit that is why I made the blend 2/3. (Map 2 has a better high end and Map 3 has a better lowend to mid. )

BTW, I made changes to my 2/3 BLEND, but not much. I also added a few pressure on the AT line. (Smoother AT shifting engagement).

I'd like to try. Can both of your maps be used on 370Z AT?

Hi ther to you all.
I like to understand what will be the best file to use with my car.
My car is 370z manual transmission with gtm stage 2 supercharger, with 11psi pulley.
Is there anyone that have the same setup and use one of the maps?

You can try it. It should work for the G35/37/350Z/370z

This is just an electronic throttle tweak.

Let me know what you think?

Could I use the tune the car has now? What about the manual gtm stage 2 with 11 psi pully? I have a friend with the exact setup as was posted.

I really have no Idea. Try the AWGD8-DD

This is just a tweak to the stock infiniti S throttle design- which gives you the power build up as you constantly pushing the gas. My tweak on this is the power start early and better highend too! This is smoother like a stock, but better responsiveness.

Can the power map be used as a daily driver? Any downsides?

Do you have access to your tune file? Would you be able to flash on your own?

Sure...I have the uprev cable. I tuned the car because I put on some mods and I used wstar's throttle chart.

AWGD8-DD throttle MAP is for Daily Driver.

AWGD8-Power you can also try. The Power MAP can be used as DD, downside is probably your gas mileage suffer. Throttle opens at lower RPM. If you can send me your Tune MAP, I can tweak yours. I am just curious where you want the power (throttle response) start in the powerband?
You already have a supercharger right? Do you want the lowend controllable? What are you trying to accomplish?

As long your tune is good (A/F ratio etc) these files should be good to go!

Anyone tried my Throttle Map? Any feedback?

This is a pretty amazing thread, thanks to everyone involved for your contributions to the community.

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!

I wanna try the power map, You have a PM
