Throttle response ?? for Ram Tech
I've read a little on the throttle response in the 5.7. My truck take .5 to .75 sec (seat of the pants feeling) to respond when I mash the gas from a stop. From what I've read this is torque management working, so my question is besides buying a predator is there any way to get rid of or minimize this? such as this procedure (or is this just another imagined fix like the steering wheel rotation press and hold the traction control button to totally turn off traction control???)
......Regarding throttle calibration...
I'm not certain if it works on the truck... but I am certain it works on the 5.7
in the challenger....this information from another forum and I can certainly
verify that it DOES make a nice change! It only takes about a minute... give it
a shot on your truck...nothing to lose!
Dodge provides these instructions regarding pedal response...
1. Insert key into ignition and turn to the ON position (do not start the car)
2. Press the accelerator pedal to the floor ... then release.
3. Turn the key to the OFF position.
4. Proceed to start and drive the car.
If your throttle was not calibrated, you should notice an immediate improvement
in throttle response. We noticed a performance increase and a flat or dead spot we
had previously had in the throttle disappeared.
I would just add three things about the throttle recalibration:
After you insert the key and turn to "ON" not start, wait for all the idiot lights
to go out. (Ck Eng Light may remain on).
After you depress the accelerator pedal to the floor, hold it for about a three
second count. (On some PCM versions, CkEngLight may start flashing here)
Most drivers notice an immediate change in throttle response, but depending
on your driving style, you may need to repeat this procedure periodically
due to the computer's adaptive programming.
