Best throttle enhancer

I use iDrive. The eco mode settings are good for technical trails where you can dial-in just the amount of throttle without overshoot.

 

I think the altering the rate of opening is far more useful than changing the pedal displacement. The lag is pretty bad and makes the truck feel more sluggish than it is. This is where “all that power” comes from that people think it adds. Stock, you can mash the pedal as fast as you can and the throttle will only open so fast.

Shortening the pedal displacement relative to throttle opening is what F’s the shift points all up and makes you truck drive and shift like a ADHD kid hopped up on sugar at Disneyland. P2s were useable to launch at WOT in straight line acceleration. There was no benefit for the P3 setting, totally worthless.

 

hp tuners, justdsms tune, legit all you need. dont waste your money on pedal commander.

 

This should enhance your throttle response:

 

I recently bought the pedal Commander and loved it! The problem with the stock set up is, no matter how quickly you press down the gas pedal the throttle body always opens up slowly. So you can’t just simply press down the gas pedal harder to replicate what this device does. However I have read so many reviews of people experiencing problems with them, check engine light, vehicle goes into limp mode etc, that I have now unplugged it.

Has anyone on here used a pedal commander for a long period of time with out issues?

 

You don't have to unplug it, you can just turn it off and it becomes a pass-thru...back to stock.

 

The rate at which the throttle body opens is a function of the airflow model used by the PCM - it remains unaltered regardless of whether or not you are using something to alter the gas pedal signal. All you are doing with something like a Pedal Commander is reducing the resolution of the gas pedal that you have available. It simply amplifies the output of the gas pedal signal going to the PCM.

In other words, unless your device is altering the code in the PCM, it isn't affecting the rate at which the throttle body opens. You may have the perception that it is opening faster, but that's not what is actually happening.

 

Thanks Mray.

Steve O, watch this video it clearly shows the throttle body opening quicker. My 0-60 time went from 6.2 down to 5.3 using the pedal commander. It’s not just a placebo effect.

To me, that test isn't valid. It is not hooked up to a running engine...the throttle body opening for any drive-by-wire setup also takes into account the airflow models, which is fed by the airflow sensors that are not included in that bench setup.

If you are getting results like that, something else is going on that I don't fully understand. WOT with the pedal commander is the same as WOT without. Opening the throttle bodies quicker makes no difference as long as the engine isn't being choked for air. Maybe that's what's happening here.

 

That's a very good description of what is going on with devices like these.

 

I was always pretty skeptical of a plug in device that would actually significantly improve the vehicles acceleration. Then one day I pulled up next to a third gen at the stop light. To my complete shock I couldn’t pull away from him.. I went 2 gears and he stayed right beside my door. I was like wtf just happened !?!. Next stop light I asked him dude what do you got ? He replied back with 2 words “pedal commander”

I used to see posts on here where guys would say stuff like “pedal commander is basically like adding 100hp” and I thought it was nonsense. But now with having actual experience using it, I completely agree.

Bone stock for me was 0-60 in the mid 7s
Added approximately 100hp got me low 6s
Pedal commander got me into very low 5s

Look on YouTube some people claim 2 seconds off the 0-60. My results are pretty typical. The air flow sensor doesnt control the throttle body position.. I didn’t notice any difference on my AFR’s in closed loop or open loop after installing the pedal commander.

 

LAAAAAWLS.


Hard data incoming.... sorry to burst your bubble.

ACTUAL data grab from a BONE stock tune on a bone stock truck. Blue line = accelerator pedal in the cab, green line = actual throttle blade opening degrees at the throttle body. Notice how quickly the throttle blade opens when you mash the throttle.... a spirit booster etc will not change that.

 

Its just the initial reaction time, its not like it does anything at wot. So yeah having it mimic you pushing the pedal down further quicker is going to give you the jump off the line.

 

What you say makes literally no sense whatsoever. It took you 100HP to drop 1 second off your 0-60 time. The pedal commander adds 0 HP. It is physically impossible to do so. Where did that additional one second drop come from? 0-60 times are dominated by traction and HP, and if you have to shift gears, how long it takes to make that shift. Something doesn't add up here.

As you can see from the data posted above, the PCM determines the rate at which the blades open. I don't know how Toyota does it, but most manufacturers aim to maintain sonic flow across the throttle blade. That's based on airflow modeling, and the MAF and MAP sensors are used in that feedback loop. Opening them sooner than needed adds zero (0) HP...I know people have tried on other platforms, and they've actually lost HP.

 

It actually took more then just the HP increase to go from mid 7s to low 6s. I also put on lighter weight rims and tires. Stock TRD blower with nothing else gets you about 30% more power, which in return makes you 10 % faster then, what can I say building a sleeper taco ain’t easy or cheap... it is what it is those are the facts about adding HP, and honestly my truck has never been on the dyno so I’m not entirely sure how much power I’m making at 8 psi with a Catless exhaust and high flow intake.

Not trying to be at all confrontational with you SteveO, but I take it you’ve never driven a vehicle with a throttle controller in it?

It’s my opinion having actually used the pedal commander that it does open up the throttle body faster as the so called “comparison” I video that I posted claimed it does lol

It’s the only logical explanation I can come up with for my vehicle accelerates so much faster with it. This device opens up the throttle body so quick you actually hear a clank lol

I just cleaned the air filter recently it’s not chocking at all. And buddy at the stop light had no reason to lie to me I don’t think.. he seemed totally legit. He said “dude driving with the pedal commander is a night and day difference” “it’s like a whole different truck” the only reason he could stay with me was cause he was in sport+.

People who have never used a pedal Commanders can tell me the vehicle isn’t quicker that’s fine, everyone is entitled to an opinion. But the real question still remains. Has anybody run one for a long period and not had issues ???

 

I dont think you realize.... there is literally NO lag STOCK, you can see it clear as day in the log from above. we are talking MAYBE 50-100ms difference between when the accelerator pedal is at 100% and the throttle blade is fully open.... a blink of an eye is around 330ms. Take the pedal commander out and i guarantee you will hear the same clank of the TB opening.... hell pull the intake off and have your buddy (with the truck off but key in) put the pedal to the floor with and without it.... no difference.

The pedal commander literally does N O T H I N G than simulate you pushing down on the throttle pedal quicker or further than you actually are, hence the placebo of "its faster"

 

Just out of curiosity... not trying to be a argumentative but have you ever driven a vehicle with a pedal commander on it ?

I take it you’re of the believe the demonstration video posted isn’t accurate. The stock oem set up opens the throttle body quicker if you simply press the pedal down quicker?

 

While that video might be legit with whatever ecu they are using.... that is simply not the case on the taco ecu and throttle body. You could literally put an on off switch instead of the throttle pedal and it wont open any quicker. The taco ecu is seeing an analog input for the throttle pedal, nothing more.

I personally have not driven a vehicle back to back with and without a pedal commander, but with the understanding of how the throttle pedal mapping is stored in the code of the ECU and how the accelerator pedal works on an electronic level, seeing something inline that simply changes what the ecu thinks you are doing with the throttle pedal, its easy to deduce that it will not effect the rate at which there is a lag of the throttle blade what so ever.

 

I have. This one:



Logged the data with HPTuners, wasn't impressed with what I saw, and promptly turned it off after having an incident earlier this year where the device caused what I'd call a pilot-induced oscillation when it broke traction in 2nd gear. The lack of gas pedal resolution kept me from being able to pedal my way out of it like I normally do. Highly dangerous in a high HP RWD car with no traction control other than my right foot.
