Pedal comander

"The throttle is only going to open as fast as its programmed from the factory..."
That isn't correct according to my seat of the pants feel and my trucks 0-60 times. It isn't even close.

 

Save up and go HPTuner route. You can make the throttle pedal ramp as quick as you want, quicker than a cable setup.

There is no way shape or form that the Pedal Commander / Spirit booster makes your truck quicker. Absolutely no way your truck is quicker 0-60 with 37's vs stock. Sorry to burst your bubble.

See below.

This is a log from a bone stock 2012+ truck (2013 MY), no pedal commander no tune. I bring up 2012+ as the 2011- trucks actually had a more aggressive throttle pedal mapping in the ECU. But thats besides the point and wont change the data.



Blue line is accelerator pedal %, Green line is the actual throttle blade angle at the throttle body. 84* open is maximum angle as defined in the code of the ecu. Notice how the Throttle blade very closely tracks the accelerator pedal. Notice how when you put your foot to the floor (100% throttle input inside the truck) the throttle blade opens as fast as it can? From the flat line on the left to where i burried my foot in the throttle and the lines start shooting up, to where it reaches maximum is ~ 3/10ths of a second. The throttle blade took ~ 50/1000ths of a second longer to open vs when the throttle pedal was at max... THATS QUICKER THAN A BLINK OF AN EYE for a "delay".

So tell me how the ECU is limiting throttle input Stock.... its not, the ONLY time the ECU will limit throttle blade angle is when traction control kicks in. Again, all these devices do is simulate you pushing further (sport mode) or less (eco mode) on the throttle pedal than you actually are. You can not "push" the throttle pedal past the maximum, you can not trick the ecu to be reprogrammed in any way with something that is inline on the throttle pedals analog input.

 

I'm learning here, so I'm not on one side or another, keep that in mind. I'm just going off what I speculate to be true, I guess?

The reason I linked that video is because using whatever it is they're using, the throttle plate moves significantly faster than without the throttle module. Are you implying that flooring it makes it open faster? (that's not the case in the video I linked of another throttle modulator, which is why I chose that video.)

I never meant to imply that it makes it quicker overall, but maybe shifted the acceleration/curve to the left on the graph if that makes sense. The claim that a truck with 37s and stock gears is faster than stock seems nuts to me. (SIGN ME UP!)

I plan to go with an actual tune, never considered these pedal modulators. If a tune can fix the issue, I think that's money better spent.

Solid info, much appreciated. I like graphs, they make me happy and prove hard evidence. Just out of sheer curiosity, do you have a map with one of the throttle modulators? I'd be curious to see the difference only because in the video I linked, there was a perceptible difference in the speed at which the throttle plate moves from fully closed to fully opened.

I love discussions like these, it's a fantastic learning experience.

 

There will be zero difference in the graph and whats actually going on with a pedal commander/spirit booster as the correlation of "X amount of pedal input" seen by the ecu (as the analog input) to "X amount of throttle blade opening" that is coded into the ecu does not (and CAN NOT) change via these devices. Again, all the ecu "sees" is you pushing the pedal down, the devices in this thread simply manipulate how much the ECU sees you pushing down the pedal by altering the voltage out of the pedal signal wire in a positive or negative fashion.

Hell you could wire in a fuggin switch and literally have an on off throttle... and the ecu would know none the wiser other than the fact you go from 0% to 100% almost instantly. (please for the love of god dont do that)

 

I had and still have no doubt you know a hell of a lot more about this topic than I do, it's not even close, I was and I still am positive about that.

However I'm ready for a match up to any completely stock non-supercharged 4.0L Tacoma to prove my point. It'd probably be fairer if the other truck had an automatic transmission like mine does. Of course TW doesn't promote street racing so we'd have to do it somewhere other than a legally monitored street.

Any takers?

 

@theolee ???

 

LOL please film it... i wanna see your face when the stock NA tacoma pulls on you.

if you are in the Ventura CA area, let me know we will find a sanctioned place.

 

Lol what shenanigans are you getting me into!? Do I need to disconnect the nitro before the drag race?

 

You don't want to see my face regardless of the situation- trust me on that one hahahaha!

I might be 107 miles from you this Sunday depending on if a sale I'm working on goes through (Irvine).

Disconnect the nitro glycerin but leave the NOS connected lol.

I mean you aren't chicken are you?

Lol jk

 

What ever, same thing lol

 

Lol!!

 

Is it the same thing as the RoarPedal?

 

Late to the party here but I have the PC on my 05 taco and after installing it the difference was immediate! I use the Sport plus 2 setting and it's great for accelerating though traffic. It's a bit steep price-wize but they offer coupons a lot on their website. I highly recommend!

 

Where is this from? Just asking because live data from the OBD2 port is typically too slow to accurately see transients less than a second in duration. It's a problem with many HUD products where for example the tach doesn't update quickly enough to be usable.

 

Data pulled via HPTuner MPVI2 I believe i have those channels set down to 50hz
