Any pedal commander users?

[RST Dana]

Selling my PC65 and thinking about getting one for my 21. What are you guys using instead? I’m not going to spend big money for a tune since I’m only keeping this ride a free more years.

There was a good thread about Pedal Commander within the last year. Do a search on Pedal Commander, and you should find it. As I remember, both sides of opinions were discussed in detail.

I can't give you any suggestions for alternates, but other members may chime in.

What is PC?

What is PC?

It is a device that goes between your has pedal connection and the car. It can increase the rate/sensitivity of the pedal movement for a more rapid feel of acceleration. I have had one on 3 so far and was well pleased.

What is PC?

Pedal Commander is not the only one, forgot what it's called, I call them pedal pumpers.

Imagine your foot going from 0%-100%. When your foot increases, GM's programming slows down how quickly the throttle opening increases,
and has a few checks to make before it 'allows' the throttle to open as far as your foot has SUGGESTED.

Pedal Pumpers exaggerate how quickly your foot asks to open the throttle, and usually opens it further than your foot has suggested.

The Pedal commander does nothing for power, all it does is re-index the pedal so if you take off from a stop at 1/4 throttle without it with the PC it might be 1/8th throttle, it just makes the pedal more sensitive that's all it does. My opinion its a waste of money

 

[Joseph Garcia]

I am with @Silverado4x4 in that PC just takes the place of your foot pushing down on the gas pedal further to get the same result. In addition, I don't think that it is necessarily great for the transmission and changing gears, as I believe that the transmission's computer (TCM) also takes information on the throttle position.

HOWEVER, many folks truly like the PC and feel that it is a benefit to them, so while opinions may vary, if you like the result after installing PC, then by all means, go for it and be happy.

There are many things in life I would consider waste of money, but what you eat don’t make be fat. My last three vehicles would spin the rear tires more easily from dead stop. May not be great for the trans, but that’s not a worry for me. It does generate more smiles at launch for sure.

Your foot position is NOT the throttle position, unless & until the ecm & tcm AGREE & APPORVE of that.
Once physical throttle cables gave way to electronic throttle SIGNALS,
your foot makes a REQUEST, that MAY, EVENTUALLY be fulfilled by the throttle,
AFTER the ecm & tcm ALLOW (whatever part of) your request to be fulfilled at a prescribed rate of fulfillment.
Your foot and the throttle's connection are tenuous at best.

Just because your FOOT goes from 0%-100% in 0.50sec,
does NOT mean the throttle will ever do that, EVEN with a pedal pumper.

As said, all the pedal pumper does is tell the ecm & tcm that
your FOOT went further than it actually did, quicker than your FOOT actually did.

ecm & tcm still decide if when & how quickly to fulfill foot's request.
This was done specifically to improve emissions, torque mgmt / powertrain longevity, and NVH;
if engine & transmission response time get a lil bit slower, so be it.

I have Roar Pedal on my 2025 yukon, since my pulsar Lt that i had on my 21 silverado doesnt fit my yukon im on Roar pedal works great, just waiting on one that can deactivate auto stop start an dfm/afm off and pedal control in one module still on the waiting list, id recommend Roar pedal i have it on sport plus, havent had any problems with it in a month

Calm down, and try spell check too. Everyone knows your opinion, and I have mine. If I want to spend my money on pink wiper blades, I will, and your rants about why it’s a waste won’t make a difference.

Everyone knows your opinion ...

Onboard realtime driving data has nothing to do with anyone's opinion. Check for yourself. It's not like I'm trying to mislead anyone; quite the opposite.

Most of us here may not be rocket scientists like yourself, but I already have multiple 0-60 times from multiple vehicles to validate my opinion. Nobody said your misleading anyone, but constantly brow beating and reposting information like you are the only person ever to discover water, is a bit annoying. There, I said it.

I bought Roar. It’s for my Mercedes S65, but it’s great! Easy to use, no issues.

I just ordered a Pedal Commander for the 2025 Yukon 5.3 in an attempt to get rid of throttle lag. They claim that the PC eliminates throttle lag. There is an off-idle lag followed by a small surge when attempting to take off from a stop slowly and it's annoying. I'm not looking for performance gains or faster 0-60 times, just smooth instant throttle, like a carbureted engine gives. I'll report back here if it works for this purpose. There is a 30 day money back guarantee, so why not give it a try.

Um, you ARE looking for a performance gain - throttle response.
Other reason why carburetted engines have such good throttle response is the physical (cable) throttle cannot be slowed or mitigated by the pcm / ecm.
With a physical throttle (DBC), your foot IS the throttle commander.
With a signal throttle (DBW), your foot makes suggestions to the pcm / ecm, which responds as much as it feels like it, when it gets around to it ... or not ...

I'll report back here if it works for this purpose. There is a 30 day money back guarantee, so why not give it a try?

It works for that purpose, no worries about that.

I put a Thornton tuning chip on my 22 Z71 5.3. Almost instantly I noticed better throttle response. Better launch and 0-60. Better mileage on the highway and overall it works. Now just curious if the transmission agrees with it long term

I installed the Pedal Commander today and test drove the Yukon XL 5.3 today.
The lag is gone. Good. I couldn't find any settings that feel close to stock without the lag. All of the settings seem to increase the throttle aggression. The Eco mode is strange, as it feels as though the brakes are dragging all of the time. I will never run that mode. I'm going to leave it in the lamest possible mode which is City -4. That to me feels closest to stock but without the lag. This vehicle is just used as a kid mover and we have other vehicles for performance driving.

If you like performance increases though, this is where it's at! It gives the truck a feeling of a much larger, more powerful, tuned engine. The sport and sport plus make the 5.3 feel like a 6.2! The transmission shifts quicker and more aggressively too. That wouldn't be due to the Pedal Commander, it would be that the TCM seeing more aggressive throttle application and it learns to shift at higher RPMs. This Pedal Commander absolutely rips. If you're looking for performance mods, I can say that this little thing is worth it for the dollars spent. Forget the cold air intake type mods, just go straight to this. On the Sport and Sport Plus modes, I was driving faster all the time. Not just 0-60 but going everywhere at a higher speed. It makes you want to go faster than normal everywhere you go.

What I really don't like about the Pedal Commander is that it doesn't feel linear at all. Depending on the setting that you use, pushing down on the gas pedal results in exponential throttle response. It's not proportional to the amount that you press the accelerator pedal. I'm not a fan of that at all. Example: driving at a steady 40mph and just barely even touch the pedal and the thing immediately pegs 4,000 RPM and marches towards 50mph. I'll keep it for a couple more weeks trying to adapt but if I don't like it then it's going back.
