And make sure you have a tuner version. =)

I did an experiment today using wstar throttle MAP vs Jordo.

Just a side note, I have a 2008 Infiniti EX35 AWD 5 speed. VQ35HR ENGINE. (297hp/253 ibs/tORQUE)
It is a bit heavier than the G37 coupe/sedan. I think mine is around 3,975 IBS.
It is not loaded so it is a lot lighter than 4k IBS EX35.

Temp outside is 47 F , on a flat surface too.

Car info : On a stock EX35 rims (heavy) with 225/60/17 snow tire (Michelin X-ice 2)

Tranny: 5 speed - used Manual mode on all runs. 45MPH where reached at the end of 1st gear at close 7.5k RPM( I did not bump the speed limiter) towards 2nd gear shift.

Jordo MAP 1st and 2nd run from top to bottom. (BELOW)

Wstar Map (Below)

http://i58.tinypic.com/2dgkglg.jpg


I alternate runs between Jordo and Wstar. Jordo 1st run, then wstar 1st run. Then I shut the engine off for 5 minutes. I did the 2nd run with Jordo map again, then did wstar. The best time was 4.15 sec 0-45 using wstar MAP. (THROTTLE MAP) and I expect to be slower since engine is hotter, but it was the best time.

I apologized for just doing 0-45 MPH. I do not have a nice stretch of local road that is safer to do these runs. Numbers are slower than the G37 i expect from 0-45 sec. =)

I have not tried 0-60 on wstar throttle map yet. I am waiting to put on my summer wheels (17.5 ibs each) - The best 0-60 run i did was 6.3 sec. flat on Cipher with summer wheels with 89 F degree weather. I expect to be faster with wstar ETC MAP.

And BTW, I after doing these runs, I decided to try ETC: OFF , but after cruising with this setting, It does not make sense to do the 0-45 sec run. It`s just weird, car does not bog down on downshift, but it does not have that seat of pants pull.

I wish I could get some comparison from you guys with the G37 0-45 sec. run. - N/A engine pls. =)

Just curious, does Jordo or wstar seem to pull stronger off the line?

jrb55gh,

Wstar kick *** off the line, the midrange is phenominal! Although, both Wstar and Jordo power start at 2.5K rpm in my car, I bet the G's must be lower due to lower gearing on the 7A/T or 6 speed manual.

In my car, I just floored it ( no torque breaking) from dead start. I need to hit 7.5k rpm to get a better 0-60 as I tried it early on my etuning phase. I experiment shifting at 7.1 -7.2 k RPM and lose about .2 -.3 secs.

I am excited to do another 0-60 run using wstar throttle map this time, but I need to install my summer rims (17.5 ibs) and tires first. I will do it next weekend.

Hmm.

I may have to try Wstar's map instead.

It might be that mine results in wheelspin, so "feels" faster, but clearly its slower.

Looking forward to more data -- thanks for sharing :tup:

Here is an interesting find with wstar's map.

There is a slight 'dip' in the throttle position between 5600rpm and 6000rpm. I am not sure if this hurts power or not but sensor reading dips from 4.2v down to below 4v.

any thoughts? :hello:

Does anyone have the stock throttle map values? I'm still fighting with getting my throttle to work at all with ETC on... damn uprev voodoo

I really need to get a hold of someone at uprev to help out with this, I'd really love to be able to drive with ETC on again. I updated uprev/rom, flashed wstar's map to map1 and stock to map2. map1 was useless as it was last time, no throttle anywhere. switched to map2 on the fly and did some tracing/logging, I see about 4.15v which was decent, felt like the throttle was almost fully open, cool. Start the car up to drive home and I'm back to the same issue I was a year ago, 2.4v when flooring it until 4k rpm, then BAM wide open throttle. I didn't touch the maps at all... days like today make me want to switch over to ecutek.

This post may not be anything special to the track guys, but there is something worth mentioning to the street guys with a 7AT. I just completed the current Dynotronics Ecutek remote tune on my 2013 7AT. The car is completely stock and street driven smoothly with restraint when the wife is along but with gusto when she’s not.

On the street in stop and go traffic the stock throttle response has an annoying delay that is actually dangerous in slow, tight situations that require quick acceleration. From what I read in this thread it appears that wstar has developed a throttle table (2300) in Uprev that cuts the delay but accelerates hard with very little throttle pedal input. This sort of throttle response is ok with the 6MT in street traffic because the clutch can be used to modulate the torque to the rear wheels. However, on 7AT cars with stock stall speeds, smooth starts in heavy traffic require extreme throttle foot control. Wstar also commented “the curves are backwards from where they should be for drivability”. Soft response without delay at small throttle pedal inputs makes street driving more relaxed and might be a benefit on the track. I think I have this now with the tune in my Z.

The first try for a suitable throttle response curve was a 1:1 coupling of the throttle pedal to the throttle. This resulted virtually in no delay but the engine almost jumps out of the car with a short ¼ throttle stab at the pedal. It was impressively quick reving in neutral but difficult to drive with an automatic on the street. After a few iterations of logging data and adjusting throttle response to throttle pedal inputs, the delay is nil and the action of the throttle is smooth and gradual at throttle pedal inputs up to about 10%, but responds like gang busters if you put your foot in it.

Can you post the hexadecimal code for the map, both the first (1:1) vs he one you arrived at?

Hex code for stock map -- note, this is from 2011 7AT

"Can you post the hexadecimal code for the map, both the first (1:1) vs he one you arrived at?"

I am not sure that I can get that code. I do not have the tuner version of the software. I will ask Joe at Dynotronics if it is available to me.

thanks Jordo, it turns out i had the stock throttle map set properly my ecu just sometimes ignores the map switch or something, im really not sure but it would behave like I wasn't on the stock throttle map at all. Now that its actually using the stock map so far the car seems OK. I'm going to have to play with this a bit when I get on the dyno...

Jordo,

I do not have access to the hex files in my Dynotronics tune for the throttle response. However, I can post the data logging graphs of the actual throttle, VVT, VVEL responses to throttle pedal input. Apparently these responses are accomplished by bypassing the Uprev throttle table and directly specifying each parameter in the Ecutek software.

The first plot is the throttle opening in degrees (green), VVEL (yellow), VVT (blue) vs. throttle pedal sensor voltage in a 2000 rpm roll on. Idle is about .7 volts and full throttle is about 4.66 volts.

The second plot is the standing start data with the VVT (blue) incorporated into the same graph.

The third plot is the throttle opening in degrees (green) and VVEL (yellow) vs. throttle pedal sensor voltage in a normal standing start.

Good new info guys! So I have been using wstar throttle map for almost a year now. My only issue with Uprev is the inconsistency of how the tune stays there without the stock ECU inhibiting the Uprev full potential. One day car pulls harder from dead stop, another day it just flat out slow. This happened in any season of the year.

When my car was Etuned by Seymore, it was in the middle of hot summer, then found out about wstart throttle map at the start of fall and used it until now. With the change of season here in the midwest, it causes my original tuned A/F fuel ratio to get leaner (winter) , so I richen it a bit. Power was good, but still one day it lags one day it is peppy. Now comes spring season , and temp ranges from 40 to 70 F , so I logged some Cipher 0 to 60 run and still the car is a bit lean at 13.8:1 on WOT. The same MAP was dialed in at 12.8-12.9:1 on WOT summer time. So I asked Seymore recently to richen the car more. Now the car seems to pull harder just buy adding more fuel at 12:8 -12.9:1 and still using wstar throttle map. For a week now the tune is very consistent. It does not run flat in torque which start low 2K RPM and pulling harder at start top of 2k and above. Temp here is up and down from the range of 40 to 75 F . I wonder if the issue is UPREV not totally taking over the ECU parameters that Uprev already broke into?

As for Wstar throttle MAP, do you guys noticed if there is any throttle restriction from below 15MPH ? just curious? Right now throttle appears responsive at less than 1/4 pedal push.
I do not track the car (I have a 2008 EX35 crossover VQ35HR 5 Speed A/T ) , but I would like to have a touchy throttle pedal starts exactly at 2K RPM not 2.3K, but as wstar title of the thread goes, it says SMoooooth..... =) I guess I need to start a new thread title Uprev Touchy Pedal. =)

Jrb55gh, how do you like the ecutek etuned? I wonder if wstar throttle MAP can still be tuned better, due to dip in some RPM points per your observation?

Also, does anyone has an idea how to work on the Torque management table? I would like to see some hex data of your torque management table. So when the tranny slips on specific RPM or gears, i have to increase the number on that specific cell on the torque table? Pls. Clarify. Thanks!

When was the last time you clean your throttle bodies? Maybe it is gummed up? The more filmed build up around the butterfly plates, the more the sensor adjust your baseline throttle and screw up the sensor reading? Not really sure if cleaning it might help? Just be careful not to open the plates when cleaning it. Work around while while it is close. It can be cleaned this way since I had done it once and I could feel the smooth acceleration after resetting the ECU using the pedal sequence reset.

Hm. I am curious as to your gearing -- it's different that the 7AT's (as is the motor!), so that might factor into both responsiveness and any quirks that might crop up.

My throttle bodies are squeaky clean, and completely unrelated to throttle on this car. For most driving scenarios the throttles are fully open and air intake is controlled using VVEL by adjusting lift, throttle % is just a simulated number.

not quite entirely there is always some amount of throttle applied to create vacuum for the brake booster. this is why the car has two map sensors

Also could somebody with logging post up a graph of a 3,4, or 5 gear pull from 2k to 7500rpm on a warm engine logging tps, vvel, vvt with voltage on the vertical and rpm on the horizontal.

Here is a data log from my Ecutek software of throttle pedal sensor and throttle opening sensor for several easy starts. It appears that the throttle roughly follows the throttle pedal and does not remain wide open. The pedal sensor voltage is in blue and the throttle opening sensor is in yellow. The second screenshot overlays the VVEL (magenta) and VVT (red). There is truly a lot going on with every movement of the throttle pedal.

Pm

Can i trouble you to post up a screenshot of your A:F tables please? (either current or the backfiring one). How bad was the backfire? I dont mind a little crackle and pop ;)

Thankyou for your time and effort in researching and refining something for the community to use. Likewise for Baer.

I've got both maps loaded at the moment and although i tried to tell myself to like Baer's one more because it is an 'upgrade' over wstar's (by no means inferior) and it reduced some of the low rpm lag for him. On tip in it actually felt worse. For example, parking the car using my normal light taps of the gas pedal and feathering the clutch almost resulted in stalling. I am running an underdriven crank pulley so that might be a factor too. During normal driving, Baer's map for me was noticeably more jerky. I thought a map designed for 7AT would feel weird on a 6MT, and a map designed for 6MT would be better for my car.

One thing i would like to note is that SRM for me while using wstar's map works much better than it ever has on my car!! I always thought the SRM feature on my car was a bit off compared to the numerous test drives i had before buying this one. It works so well that i even get a smooth engine braking action when going down gears. With Baer's map, i got a lot of jerky shifts - mainly upshifts though. Downshifting was not much different from stock. I dont think it's a coincidence because when switch between maps on the fly, the effect is instantly noticeable.

Again, i'm not saying either map is superior/inferior. For my driving style and personal preferences, wstar's map is my choice. I didnt have a chance to test out both maps at higher rpm (4000+).

^^^ It might also be worthwhile to log ST and LT fuel trims on tip-in or just before or after -- there may be some big transitions in the fueling that the ECU is trying to sort out.

i still need to get a windows netbook haha i've been using my 15" macbook pro which has USB ports on the left side only, on a RHD that means the screen faces the passenger's door :(

over what period of time should the datalogging be done?

Maybe a big empty parking lot if you are launching it -- or anywhere where your commute would reflect stop and go driving. Basically, you just want to see what the ECU is doing on tip in or whenveer you have been feeling any hesitation.

is it true that each time you flash an update to the ECU, the fuel trims are reset?

I have to reset the damn pop up bonnet lamp every time i flash!

I still need to play with throttle mapping. Thanks for throttle tables.

One question guys, can we take on these hex and post it straight onto ECUTEK table ? Or is it a totally different table altogether and not compatible. I would like to have the same throttle response but in ECUTEK, at least something to base on when i go to talk to my tuner later. I believe he didn't play around this table since it is the first time for him to tune 370z.

Note : I'm in Malaysia.

Theoretically, yes... the hexcode is what the ECU sees, so I would expect both ROM flashing softwares have to interpolate the same code in order to change the ECU maps. Just make sure you are pasting the code into the same table -- it's possible that ECUtek accesses different tables.

At least one of the maps posted here should have both hex and screen shot from uprev so you should be able to copy, paste, compare.

Thanks Jordo, will be tuning my 7AT with this 2300 map later to eliminate that terrible hesitation then launch at 2-3k thing.

hi
is it ok to use the map (2300 map)on a supercharged car ?
will it work good ? no issue's ?

Yeah, I'd like to know too. Thanks

thanks :)
Bart

Why not? It should not be a problem if you are the drift king... :tup:

Kidding aside, it should work, but you might lose traction early in the RPM band. Not a good thing in wet weather. (Fish tail). I do not have a supercharger in my car, but the rear easily broke loose when I gas it during a slight turn on wet weather. Mine is even an AWD.

BTW, what is the RPM in your car when it starts to build boost?
Are you getting bored with the 550 RWHP ? =)

i install the 2300 file it fils real good . it files match quicker then before
about the loosing control , the pilot cup 2 +race logic solve the problem

''Are you getting bored with the 550 RWHP ? =)''

not yet : )


the dyno run is on a dynapak dyno that measures the hp\tq on the hub

the boost starts at 3200 rpm if i remember right

I have wstar's 2300 map loaded along with Awgd8's 5AT map even though I have a 7AT. Both are very good and smooth. I think awgd8s is just slightly more aggressive in the midrange up compared to the 2300 on the 7AT.

I'll be driving for a week straight on one and then another to get better impressions. Both seem like good options though.

Great car man! Do you still have stock internals? If wstar 2300 file is not enough, feel free to try my wstar modified awgd8 file. ( credit to wstar for giving us the base 2300 file). :happydance:

Subscribed! I would like to know your impression using my tweaked (awgd8 5 AT) wstar file.
Have you guys ran the car in the 1/4 mile with stock ecu vs wstar/modified?

I did try wstar 2300 lowend from 0-45MPH (from dead stop)
-- Manual mode no break torque: 4.15 secs (cipher)
-- DS mode with 2.5K break torque : 4.02 secs (cipher)

Unfortunately, my best run 0-60 is only 6.3 secs. :icon14: My AWD is almost 2 tons! (EX35 AWD)

I have not tried my modified (awgd8 5AT) wstar yet, but I would really like to
know if you guys could data log Cipher certified :tup: (0-45 and 0-60 MPH) runs using stock, 2300 and AWGd8 files. :driving:

Double post...

hi
yes still have stock internals
i will install it now id like to try it
