Better Throtle Response ?

[Vulture]

I have read and heard that there is a way to make our throttle response more like a cable driven system. Nothing against the throttle by wire set-up, but if I can get it act more conventionally, all the better. I have also heard that there is a debate about whether it make any difference, seat of the pants or otherwise. Can anyone shed some light on this. A list of the step by step procedure would be helpfull. :rck:

Here's the steps you need to follow:
Find an unused section of road with a good spot to pull-off/turn-around. (make sure it's deserted or you could end up adding a ticket to the time/gas costs of trying this trick!) :thatfunny

1.Pull off of the road and shut your car off.

2.Turn your key to the "On" position (but don't start the car), and wait for the 'idiot' lights to go out.

3.Press down on the accelerator, and let it back up.

4.Turn your car off.

5.Re-start your car and cruise up and down the road testing your throttle responsiveness.

Depending on how fast/slow you do the 4th step, your throttle will either become more or less sensitive/responsive.

Repeat steps #1 through #5 as needed until you're satisfied that your throttle response is as good as it's going to get.

I have not had the chance to actually test the procedure but seat of the pants response does seem to change.

[Vulture]

Thanks for the info MagnumFreak. As always I can count on you to have the answers.

[BlanchMan]

Ya, MagnumFreak is pretty freaky. What were you for Halloween, MF ???

Where did you learn of this trick?

[Curt's RT Hemi]

Nice pointer, thanks...
Say... you don't know how to take ESP totally offline do you?

[IDSmoker]

You can completely disable the ESP by pulling one of the fuses (#30 I think), but it will also disable the ABS!

I wouldn't try it except maybe at the track or on a dyno.

I know this is probably an old thread....

But I was wondering what would happen if you didn't push the gas peddle down the whole way?? How does this affect the calibration??

[Cal Jeff]

Hey Freak where do you get this information. Do you know what information is being displayed when you press the Note button and the North button on the steering whel controls?

[flhthemi]

If you press and hold the north button only the calibration for the compass will come up.

[MagnumFreak]

Hey Freak where do you get this information. Do you know what information is being displayed when you press the Note button and the North button on the steering whel controls?


Yup calibration procedure for compass.

I got the throttle cal info from another forum. Some people say they feel a difference others have said no difference.

[flhthemi]

>what information is being displayed when you press the Note button and the North >button on the steering whel controls?

Very interesting stuff...have any of you guys tried this?

I see on my display

Speed
Tac
Engine Temp

And if you use the page buttone there is even more to see....like average temp for the day? Man there's stuff in there I can't figure out what the abreavations stand for.... its cool!

You have to hold both buttons for about 5 seconds to see it come up.

[MagnumFreak]

What you are referring to is the maintenance display. There is a ton of info available in there. Oil pressure, MPH, fuel tank size, level feedback from both fuel sensors (tank is a saddle style), average level, pedal position, instantaneous outside temp, average outside temp, software version, vehicle message manager messages, etc. Some other stuff I can't seem to remember right now. Really fun set of displays to play with.

[traumamama]

i decided to try the steps to improve the throttle response time. i do believe it worked, that is according to my husband now suffering from whiplash after slamming his head to head rest on take off !!!!! :thatfunny i definitely feel a difference. I do LOVE this car!! of course after driving an underpowered v6 EXPLODER for 8 years with a bad transmission , anything would be fun :rck:

[flhthemi]

New Find:

Today, while still trying to get the total time on the car to display, I was pressing the trip re-set button. While keeping the button pressed (the one to the lower right of the gas guage) I turned off the ignition. While stilll holding it in I switched the ignition back on to the acc position (I think) ALL the idiot lights flashed 2 times then the text display in the speedo showed a solid green line where text would be and cycled through all three of the lines...like a rolling bar....then OK appeared in the middle line. I must have either reset or tested something but I dunno what.

Anyone got any ideas?

Make sure the ignition is off, press and hold the button, turn the ignition on to the ACC postion and wait about 15 seconds. It should appear. DO NOT start the engine. As soon as you do, it will revert to the normal mileage displays.

[flhthemi]

I can't figure out what i'm doing different/wrong....I KNOW it's not rocket science....but I still don't see the total hours. Anyway, what i wanna know now is what did I do when all these lights flashed and and the speedo did what it did and then ended the sequence with "DONE" not OK like I said in previous post.

:stupid:

There may be a way we can tell if there is actually a difference....if you put your display in maintenance mode (Press the button with the note on it and the one that displays the compass at the same time and hold for 10 secs) there is a display that shows the throttle position. Seems feasible to me that before you made a change you could rev the engine to 2000 RPM see what the throttle is reading. Then set the throttle responce and go back and rev to 2000 again and see whut ya got! Hummmmm? Or is this too logical?

:huh: I tried to "Turn your car off." fast/slow, but it just seems to be either on or off!! Sometimes slowly just to Acc, sometimes quickly all the way to Lock!! I do notice that the throttle is sometimes very sensitive in On, but not sensitive at all in Acc or Lock!! :dunno:

[MattRobertson]

I just got my RT back from the dealer, where one of the things they did was disconnect the battery and reset the computer (they finally put in my remote start and UConnect). First thing I noticed was that throttle response had taken a freakin' nose dive. Remembering this thread, I tried this trick and HOLY COW! Went from a godawful slow response -- maybe as much as a 1/2 second lag -- to near instant.

Fourteen, I think you're doing this wrong. Steps 3 and 4 restated to what I did:

(after waiting for all but the battery drain idiot lights to go off... don't think that one goes off... maybe 30-45 secs)

3. Tromp on the peddle. All the way down. *slide your foot to the edge so its barely on the pedal, and let it slip off. Do it right and this will get you a near instant-off on the pedal release.

4. turn your ignition key from ON to LOCK in one fast motion, timed to mesh with the pedal's full return.

Do the above and Step 4 should be completed just a hair after Step 3. The results were, for me at least deailng with a near-default computer, instant and amazing.

Of course be careful you don't twist the key so hard you break it in the housing. I know you know that but my lawyer made me say it. :D

[armadillo]

I reprogramed the throttle response in my R/T about three months ago, it made a definate difference, and I have been driving it occasionally since but not very hard, it seems that the throttle response may have reverted back to it's old ways, I re-did it again yesterday and seems to be much improved. Anybody else notice this (I must admit it could be just me :o )

[FOURTEEN]

Thanks! I tried it again by quickly stabbing the throttle to the floor and releasing it. I'll test it, but not today!! We just started an ice storm!! :drivingz:

[gsjoe]

I tried this procedure. What I noticed seemed to be not so much quicker response time but tighter. In other words, the delay was still there but the same short stab on the pedal gave a higher rpm response. These would tend to make a full throttle in half the distance of pedal push.

[grinner]

I tried it today in my wife's car. Didn't notice a difference.
It may just be missing mine but hers seems quite slower by comparison. She's noticed it too. I did add a 360 air intake to mine but I'm talkin about before that and it didn't make as big of a difference in performance as it did the sound.
Also, hers makes a wacky pop sound every now and again while backing up on a cold moring. Sounds like someone threw a small rock at the car sometimes. It seems like I saw a thread concerning this describing it as a windshield crackin' noise?
I noticed today as well that hers doesn't have the little roll out vinyl cover thingy that goes over the cargo area. Mine's in da shed so I'll just put it in there tomorrow.
Strange how much these cars can vary from vehicle to vehicle.

[biged6464]

you're so right Grinner....damn DC just grabs at random from the different parts bins....there are so many variations of our vehicles it's sick..albeit small things but still...look for the coinholder thread for the 3G Ram...or the underhood/ashtray light threads on the 3G Ram forums....drives everyone nuts!!

Just to clear up any possible confusion, this line should read:
Depending on how fast/slow you do the 3rd step, your throttle will either become more or less sensitive/responsive.

[grinner]

I was quick on it when I did it. Is that the point or do I wanna hold it down a while or what?

[MattRobertson]

Hmm. I wasn't, really. I was going by the original instrs and trying to time step 4 to be an instant after 3. I wonder if I can make to mo' better. Sure was awfully fast when I did it last time.

Can't hurt to try and do both I s'pose.

So I wonder what it is we're actually doing here? Are we giving the computer time to log WOT data in its read-only memory but not giving it enough time to write some sort of followup info?

[Navyvet]

When you reset your throttle response you should depress the gas peddle (key on, engine lights off, engine off) for a 5 second count. This is typical of German cars, transmissions, that have "throttle by wire" systems. My A6 4.2 and BMW both do this. Usually you need to re-set this every so often as the ECM adapts to your style of driving, or after re-setting you could always drive w/ lead boots on.

[grinner]

that may be the key.
Mine shags ass and Nan's is pokey. She drives slow with slow acceleration and I, well, I shag ass.
I try again with hers though.
So on the 5 second count... do I wanna quickly floor it and count to five or to I wanna take five seconds to hit the floor?
Sorry for the basic questions but I've tried a few different combos and have come up with the same result.

[sheezdoc]

Lol...me too grinner. Freakin amazing how many variables we can come up with for something seemingly so simple.

[Navyvet]

Just push the peddle to the floor normally and then count to five. I learned this on my first BMW and it's been true for every Audi, BMW, and Merc I've driven since. When it was first figured out there were also the same variables until an enthusiest used a Ross-tech OBD and could demonstrate actual changes and specific procedures for "resetting the throttle" on German cars. Remember once you reset your system, go for a few burn outs and some spirited driving for the ECM to take information and calculate a new response curve. My wife drives an M3 with SMG. After I drive it she complains that just touching the pedal launches the car!
(this procedure works on Merc 4matic trannys just like the 4matic's in our Magnum R/T's)

[gsjoe]

I did find that to be true as I posted previous. A short press does give a launch. I guess there is no way to make it feel like a cable response.
But, maybe this is better and I'm just not used to the difference. Sometime different is good. :cool: Thanks for all the fine tips guys, keep up the work.
How about some input on this jetchip. I called and it is in stock and ready for sale. They claim big gains with the "S" series.

WOW !! What a kick in the A** !! I just picked up my RT/AWD this weekend. With only 16 miles on it, I wasn't too sure what to expect, but I wasn't too thrilled about the initial off line pick up. I thought it was Mass over HP that made it sluggish. BUT then I read this thread about throttle adjustment. I tried it in the garage, then took the car out for a ride. I almost messed myself !! It was a different car ! Now I'm hooked.

I would recommend this to anyone ! Holy Sh**T !!!!

[leereed123]

it's called a fly by wire acceleration system,BMW's had it for a couple of years, what it does is learn your driving habits and calibrates acceleration and shift points to better conform to your driving style. if you let someone else drive your car for a week and then get it back you will notice a HUGE differance in how it drives. BIG NOTE: DO NOT use any floor mats that sit on top of your gas pedal or let itslide forward and rest on the pedal. it will confuse the computer when you hit the brakes and think you are driving with your left foot on the brake and will totally screw up your throttle response.if it gets screwed up, unhook the battery for 20min to do a battery reset and then follow the "setting thottle response steps" and get ready for the fun. Hope this helps.

[leereed123]

p.s. Jet chips suck... they totally screw with the computer and can actually give you worse proformance depending on how the ecm reads the info.... or you could do like one of my customers did... buy a new ecm because the chip fried it.. not good.

Which method did you use. The press it to the floor and realease, or press it to the floor and leave it there for 5 seconds?

[Cal Jeff]

I tried it a few days ago. By the trusted SOMP it makes her much more responsive. As soon as I get some time. Pronounced next year. I going to Seares Point to get a time slip

[allpont]

Tampahemi...I went step by step as listed earlier...Key On, idiot lights out, Pedal to the floor (I didn't count to 5), then as I released my foot off the gas, I turned the key to lock(off). That's it.

I really didn't expect much, but I didn't want to return home from my test drive. I talked to an SE owner today, he tried the same thing and it worked for him as well. Good luck and enjoy !!
