Help: Pedal, Exelleration Slow Response

[tw557]

I think PBD is the same as most at $250.

I appreciate all help from all people. I have sent Wengerd and Extreme Tuning asking what they can do to correct not only slow throttle response but slow transmission shifts and the dead HP spot over 5k rpm. Thank you and others for your help.

I have worked with Wengerd and Ortiz on multiple customer cars and Ortiz tunes my personal vehicles. I can't recommend either one of them enough especially if you are looking for drive ability tweaks. They will both spend the time to dial in the car for WOT as well as putting around town, and everything in between. Luis Ortiz has a really interesting roll racing tune to ask about for the 6/10R80s. You go from highway cruising to race ready in just a few seconds.

Well this certainly sounds interesting. Do you know off hand if he will tune with the SCT X4 before I contact him? Do you have this tune and how does it change its characteristics? Throttle position?

I for one am looking for the same thing as you. I have contacted Ortiz Performance and getting all of the specifics for my application now. I will definitely post the differences. Ortiz said they will tune for my specific application to my satisfaction. We Will See how this goes. Because if I cannot correct all of the things my OEM car has, I will have a hard time justifying a FI system this winter. Thanks

QUIT YOUR CRAP. IF ANYONE FALLS FOR THAT STUPID SHIT THEY ARE DUMBER THAN A BOX OF ROCKS AND DESERVE TO HAVE THEIR MONEY TAKEN FROM THEM.

TUNE YOUR CAR AND DO IT RIGHT OR DON'T DO IT AT ALL.

Seriously. From my recent experience from 2 very good tuners I have gained virtually no more actual HP from the tune since I am all stock. BUT, my throttle response is now much more responsive. So they juiced up the throttle tables which is about exactly the same thing the throttle enhancers do. So why is it great when a tuner does it but not a pedalmax?

A tune is actually altering your ecu/tcm to understand and calculate for new parameters. It allows the car to do the thinking like it would from the factory. A pedal commander is creating false data and forcing it into the system hoping to achieve desired results. You are relying on some random box to force feed your car fake data.

You should get a real tuner. Wengerd Tuning or Ortiz performance, it will open your eyes to a whole new world of possibilities and a much better driving experience.

 

[givemeadollar]

Obviously you have never worked with a real tuner or HP software.

Trans tuning and drive by wire alterations are both very much a thing within HP tuners unless you are using some shitty tuner. Which for you is probably the issue.

Like I said, get a real tuner even Lund and PBD can sensitize and desensitize the pedal. If your tuner can't they are certainly not capable of tuning an s550

But quit spewing your BS since its obvious you have no knowledge...

Have you tuned a car? Do you know first hand experience that this is as easy to do as you say? I really do consider playing with HP tuners one day if this true. Can I easily adjust this then? I consider Shaun form AED as a very real tuner and here is the response he gave me a couple months ago when I planned to tune with him: "you want ‘throttle response’ for street light to street light ‘feel’. We actually do not do this, it’s FAR more complicated than most realize. Just use the sport mode"

PBD sure feel and look like they did amp up the throttle but sometimes its too jumpy and other spots its just ok. I have no adjustment for this. In theory what you say sounds good to "do it right" and adjust the throttle tables but I do not think that it is easy or controllable in the sea of variables, parameters and tables in the software. Honestly the pedal enhancers are a very simple concept, have a value enter the box and a controlled different value leave the box. I'm a manufacturing engineer and in automation its done like this all the time. Turn this knob or that parameter to change the speed of a motor or the distance something moves. I just don't get the hate for the device but the endorsment when a tuner does it. Its been like this forever though.

One thing I will admit strongly, there is no way these units should be the price they are for what they are. I picked my used Pedalmax up for $125 and then sold it for $125 when I got my PBD tune. But now I'm asking them to give me stock throttle tables so I might just be looking for a used one again.

I'm basing my knowledge of what Shaun AED told me vs what you are telling me. And I'm pretty sure he is a VERY capable s550 tuner.

Honestly I've never bothered with AED. So I can't say what they are capable of. But this is a big red flag to me if a tuner is not willing to take the time to do the little adjustments to make the car retain oem driveability.

It reminds me why I avoid the big name tuners. They all like to go back to their "libraries" of tunes type in your mods and poof heres a tune we made on a car that wasn't yours but its the same mods so it will be fine... Also we only did dyno tuning so at WOT the car is phenomenal but we didn't bother with around town driving because its not race car shit.

I can do some basics but I would not trust myself to do a tune from the ground up. That is why I work with Ortiz performance for my customer cars as well as my personal cars, Luis is an absolutely amazing tuner that takes his time to build every tune to perfection from the ground up. You want around town driveability, not a problem. Peddle sensitized or desensitized not a problem, might be a couple revisions to get it dead on how you like it but it gets done.

You are 100% correct, sensitizing and desensitizing the gas peddle is no easy feat there are quite a few tables and values that need to be adjusted and it's also a very subjective part of the tune. Some people want to have a very touchy peddle some want a nice lazy peddle.

To go back to your metaphor of turning the dial and adjusting things, that would be like a tune change the input so that the computer can do the math to change the output accordingly. The pedal commanders are forcing false data into the ecu/tcm to try to get the car to do what it wants.

 

[givemeadollar]

Don't make me laugh, if they can't sensitize/desensitize your peddle you are just wasting your time with some weird red necks that don't know their head from a hole in the ground.

Enjoy your shitty tune that needs a bandaid to function properly and keep dreaming about being fast.

Show me a 7 or even 8 second car that needs a pedal commander.... I'll give you a hint, there aren't any since no one that is fast is interested in that ricer shit.

Want to see some pedal commanders go visit the Honda boys and see what them genX civics are doing. They are closer to your speed with 11 and 12 second 1/4 miles...

I would love to do my own tuning especially related to the transmission. I assume my only option would be HP Tuners. In my younger days of Kart racing then Roadbike racing, I loved test, analyse and tuning. But those were the good old days or carbs. That last Bike was tuned with Powercommander that coincidently tuned buy he same method of the Pedalmax stuff. It would see the fuel pulse from the computer and then add or subtract to change fuel ratio. We would need to tap into the fuel injector harness. I do realize a stock N/A car has very little outright power gain from a tune. And oddly my preloaded 93 SCT tune seems to be about the best.

I 100% agree that WOT tuning is really so irrelevant but at the same time its the only thing that has a controlled test. I actually almost never, other then testing, go wot. I'm all about the whole driving experience. I am sure that PBD just pulled a tune out of a library and sent it which I guess is pretty fine since I have no mods other then 18 airbox. I asked PBD if they will adjust my trans to my liking if I went with them. They said yes but with the countless hours into this tune I should be good. Well it was fun for about 5 min then it was untolerable. Awesome to go down the strip but wincing shifts on the street. They did adjust better but still not great. I now have asked for stock parameters for the trans.

I have not counted out I will try a truck manifold one day and VMP was the only place that agreed to help tune that in. Then PBD because everyone raves so much. But I do which I would have given Ortiz a shot. And maybe I will soon too. I like to here he will help get me to the driving experience I am after. But after this past experience, I would have been better off to go with SCT preloaded tune, adjust shift pressures and then adjust the throttle with a Sprint booster or the pedalmax was nice with the control knob. Turn it up for Drive mode and down for Sport mode to my liking or when my daughter or wife would drive it.
