Well, I was on the way home from watching Evan Almighty (good movie, btw) with my little brother tonight. We've been doing a lot of work on his Dodge Charger lately, and he mentioned something about recalibrating his gas pedal. I've never heard of that before, but it seemed to make sense since a lot of new cars (and our Tacos, I belive) have electronic controlled throttle systems.
This is what he did: Turned the key to "on" positions and let everything normalize (lights shut-off, etc). He then pressed the gas pedal in a smooth motion all the way to full throttle, then let-off in a smooth motion all the way to resting. He waited five seconds and did it again. He said his throttle response went back to almost like new.
I've noticed a difference between how my throttle (56k miles) and my buddy's (12k miles) is. His is definitely more responsive, but he hasn't done any modifications to his truck. I've done quite a few to include "deckplate mod", secondary air filter removal, and a dual conversion on the exhaust. On the low-end, my throttle response is noticeable more sluggish than his, but at peak RPMs mine is much better.
Anyhow, I was sceptical about this 'calibration', so I pulled the truck over and tried it. Turned key to on, waited for lights to stabilize, smooth accel, smooth decel, waited 5 seconds, repeated. I started the truck again and it seemed to have made a difference in my throttle response.
Now, the reason I'm posting is because I want to know if anyone else has tried it; if this 'calibration' would even actually work on our truck; or am I getting the "K&N I feel more horsepower in the seat of my pants" effect? I swear it felt to me like the throttle responded better, so now I'm curious if there's some truth to it.

I used to do that on my Dodge Ram, and it definitely helped calibrate the throttle, but not sure if it will work with toyotas..........I'll give it a shot tomorrow

I think the idea is that the drive-by-wire system "learns" your driving habits much like the transmission. You'd be "calibrating" or "resetting" your throttle back to stock, therefore giving more throttle response. I, personally, don't think it will do anything, but it won't hurt to try it.
The only way to tell is if you have an accelerometer and you could measure your 0-60 times before and after.
.
well luckily i just happen to have an accelerometer in my truck but my truck is a 6 speed so to get 0-60 times is nearly impossible but ill try it and tell you what the accelerometer says
I've reset the computer before by pulling fuses when I did the deckplate mod and pulled the secondary air filter. I noticed a difference in the throttle then, too. I'm just curious if this 'retrain' thing works or if I'm imagining things.

i think i have an excuse to go to the drag strip this weekend i already have gone and every run i was within a tenth of a second (which is pretty consistent for driving a standard) so ill "reset" or "recalibrate" AT the drag strip and see if i get any different numbers
