Just Did Throttle Reset - WOW!
After 3 months of ownership I was a bit disappointed with pickup and the lag in throttle response. I had read on this forum about Throttle Reset and the Sprint Booster, but I was reluctant to try either. Well, I finally decided to try the Reset. I did as the instructions said (courtesy for an Forum member) and WOW - what a difference! :p Why didn't DC set the car like this during Prep? The car is sooo much quicker and I have zero throttle lag. It's like driving a different car. If anyone hasn't done the Throttle Reset yet, do it NOW!!! You will be amazed.

Copied from here: https://www.crossfireforum.org/forum/131929-post17.html
The Throttle is "Drive By Wire" and adapts to your particular driving style. Do a TBA Throttle body adaptation. 1. Get in your car, it doesn't matter if you close the door or not. 2. Turn the key to the on (not start) position, the position just before the starter turns over. 3. Press the gas pedal to the floor with the key in the "on" position. 4. Hold the pedal to the floor for five seconds, then turn the key back to the "off" position (don't remove the key), then release the gas pedal. 5. Wait 2 mins. for a full alignment. 6. Drive the car as you always do. Depending on your driving style, this may or may not be a big factor. I do a lot of city driving so I noticed a big change after erasing my history. It is not hard to do this, just follow the instructions - Key on, pedal down, 5 sec, key off pedal up, wait 2 minutes. Keep the key in for the entire thing. If this doesn't work, disconnect your neg. battery cable for 20 minutes. This will re-set the parameters in the drive-by-wire... Unfortunately it will delete your pre-set radio stations, clock etc. as well... |
Re: Just Did Throttle Reset - WOW!
I did this the other day as well since the ridiculous throttle lag was driving me nuts!! On downshifting there was no way to blip the throttle - unless you like to push a long travel pedal all the way to the floor just for a "blip". After a quick reset the car is almost transformed!!! I think I'll save the Sprint Booster money for a while now!!

Re: Just Did Throttle Reset - WOW!
After having the car about a month I thought I would give the adjustment a try. WOW! it feels like a bought a different car. I think it even sounds better.
Amazing how much difference this simple task can make. |
Re: Just Did Throttle Reset - WOW!
Keep in mind that this throttle reset will only work until the car 'learns' you're new driving habits... then the lag will start to come back.
I'd reset it every week or sooner if you can't even stand a little lag. Cheers! |
Re: Just Did Throttle Reset - WOW!
Does anyone know what exactly is causing the lag and why does it exist? Can a dealer permanently address the lag?
|
Re: Just Did Throttle Reset - WOW!
Hmmm, I tried the reset and noticed no difference at all. Do you have to count to exactly 120 seconds (2 minutes)? I think I went a little over that...

I would also like to know. |

I would also like to know. Regarding the reset process, who came up with this procedure? Is it in some manual, and why is it only temporary? In other words, how does the vehicle "learn" your driving habits and adjust to them? |
Re: Just Did Throttle Reset - WOW!
The vehicle was designed to learn the individual habits of it's driver as a safety measure. In the event the driver does something out of the ordinary (mash the pedal to the floor), there is about a second for the driver to recover so the vehicle doesn't go out of control.
It also allows the vehicle to learn more aggressive driving habits, but those are harder to be consistent with. The reset was most likely designed so as to allow a new owner to quickly wipe the learned data or if there were two drivers sharing the car. This way the learned data does not interfere with the next driver's habits. The reason we find it so detrimental, is that once in a while we want to 'get on it' and there is that annoying lag. Why? Because during every day traffic driving we have been conservative... easy on the gas in crowded freeways and slow braking in city traffic. The car learns the majority of your driving style... so when you 'get on it', it's outside of that normal learned data and the car believes it is not safe to let you do so right away, giving you that safety margin. My Sprint Booster permanently removed this 'lag'. Some people don't like the Sprint Booster, but most love it. Hope that helps. Cheers! |

So, I take it that this "learning process" is constant. No matter how many times you reset, it will eventually reset again, on its own.

The PCM recognizes how the accelerator pedal is being pressed and switches between a few characteristic curves. Eighty percent of the engine’s power is achieved for a pedal travel of about 50% for an aggressive driver and about 40% for a conservative driver. There is no further difference felt above a pedal travel of about 90%. The characteristic curve for a conservative driver is active after a long drive. Then the accelerator pedal must be pressed down unusually hard to obtain a higher acceleration level. |
Re: Just Did Throttle Reset - WOW!
Does this work on the six-speed?

Re: Just Did Throttle Reset - WOW!
ANY crossfire has the drive-by-wire system and will also have the 'learning' part that can be reset.
Cheers! |

Re: Just Did Throttle Reset - WOW!
I gave this a try Saturday and it seemed to give my car a jolt of caffeine.
One bit of weirdness. This may only be coincidence but after I did the reset the spoiler didn't deploy on the freeway. I had to open and shut it twice by hand to get it to beep and then it was fine. Is that crazy? Surely that didn't have anything to do with it but I had not moved it with the switch in a long time. I know that can make the auto-deploy not work occasionally. |
Re: Just Did Throttle Reset - WOW!
Now I'm depressed :( - the Throttle Reset only lasted 7 days. I noticed degradation in performance last night and did a reset again this morning to see it there was a difference, and yes there was. I don't want to have to do this weekly.
Ok, can someone explain this to me... it's a computer that is doing a reset - imposing the lag - why can't the computer be reset to permanently eliminate the lag? I don't want to use an after market product (Sprint Booster) as it fixes the problem but I want to eliminate the cause. Comments? Also, HDDP, where did you get the Throttle Reset info? You can't make this stuff up... i.e. Stop the Car, leave key in ignition, put right finger in left nostril, close left eye, turn lights on, cough, count to 30, your car should now be a Ferrari and you should look like Brad Pitt (but it will only last 7 days - which would probably be OK). :rolleyes: |
Re: Just Did Throttle Reset - WOW!
CDT that last comment almost made me pee my pants thanks for the laugh... :D

Re: Just Did Throttle Reset - WOW!
I'm not sure were the throttle reset instructions came from, but I'd bet it was from a Mercedes owner or mechanic. :D
