After almost 20k miles of driving my jeep (12 2 door manual) the lag from the gas pedal has driven me nuts. I've never stalled a vehicle as much as I have with my JK. With the fact that I've owned a lifted manual truck before with 33's and a lot less HP than my jeep has, and that this is far from my first manual vehicle, I can't chalk it up to me just being bad and driving a manual vehicle.
After seeing an ad for a throttle response tuner for another type of vehicle(and never knowing something like that exists) I did some digging around on forums. Apparently this is a common issue people have with their JK wranglers. Most people say those tuners that only affect the throttle response don't even work but everyone who has actually bought and used one said its night and day difference. But for $300, its a hard pill to swallow.
Screwing around with my data logger I came across this.
each line is 1/10th of a second. the second line in throttle input percentage, and the 3rd line is RPM. *NOTE* the RPM was logged 1k higher than it really was. No idea why it did this since when I had it set to .5 second intervals right before this log, it was fine so the 1692 rpm is really 692 rpm (idle rpm)
This test was just sitting in neutral and revving the engine.
I also have video I took late at night showing me pressing down on the gas and then you hear the engine rpm increase a moment later.
I'm also able while driving in gear to step on the gas and let go quickly without any input going to the engine. I'm able to press the gas about 3/4ths of the way down and not have any response from the vehicle.
(i'm not sure how I can upload these videos yet)
I do not believe any of my sensors are bad since it seems to be a common issue from what I understand.
Does anyone else experience this? I tried the whole re-calibration test thingy they say you can do but that did nothing.
