For the guys with the PC's have you tried removing and re-installing it to see if maybe it lost calibration?
Just a thought

Just a thought

I've had my PC for about two years now on a 2020 3500 Cummins. I had it go off on me several times about a year ago. Two things, first it didn't go into limp mode.

Limp mode to me means the same as when you run out of DEF, 5mph speed limit. Instead I immediately noticed a lack of throttle response. My opinion is it just went back to pre-PC mode. Maybe it's a safety setting in the ECU to reduce the output when it detects a bad signal. In any case I was still able to drive my truck.

To resolve my issue I would reset the CEL, unplug and replug in the PC and try again. It would work but kept going off every day or so. It went off it in different spots typically on a side road or my driveway. Very random.

When I initially installed it I was lazy and didn't zip tie the cable so it was hanging down. The next time I unplugged and re-plugged it I tucked the cable up nice and tight and zip tied it. I haven't had a problem with it since.

So for everyone having this issue try securing the cable so it isn't just hanging there. It seemed to solve my issue.

It seems a lot of folks, mostly the ones who haven't researched them, don't understand how the controllers work. Think of it this way. Stock FBY is a controller, exactly like the aftermarket ones, except set at factory specs. (speed) and not adjustable. They take appx. 4 sec. to fully open the throttle plate, doesn't matter if you take 4 sec. to push to the pedal to the floor or tromp it as fast as possible, the throttle won't be fully open for appx. 4 sec. With a controller set to the middle setting the exact same thing happens, but within only 2 sec., and on the highest setting the throttle will open almost immediately, just like back when there was a linkage or cable operated throttle. Some controllers have an economy mode, those eco. settings will change the throttle plate response time to an even slower response time than the factory setting, These modes can be duplicated by pushing the pedal slower, but the plus settings could never be duplicated by pushing the pedal faster, the OEM controller won't let it happen.

If the 4 sec to full open is accurate (which I would not dispute), have there been any accidents due to this?

I drive a lot on 4 lane rural roads. When making left turns, I have had 3 or 4 instances where the SLOWWWWW stock response made me sweat bullets. Push the pedal and nothing for several seconds. Mean while the approaching car has come much closer...

Has anyone involved FCA in this discussion because it seems to me that SAFETY has been ignored to gain MPG? One or two seconds I could understand but 3 to 4 is getting dangerous. AI might be good in some instances but can NOT replace what the driver sees...

You're driving a full size truck with a small diesel that relies on turbocharging to make power. Take a look at the stock dyno results for your truck and you'll see why it feels slow off the line. It is. 0-60 times are in the high 7s to mid 8s with a proper launch (depending on weight due to options and model) and in the 10s from idle to floored. It's not going to be quick off the line without real modifications.

Diesels can make monster power if you're not concerned with keeping the emissions compliant, are willing to upgrade turbos, reprogram, etc but that's not what you have. You are simply not going to make power until the turbos are spun up. If you need to pull out with some authority you'll need to two foot drive. Hold the brake and spool the motor up a bit to get the turbos engaged and that's as good as you're going to get.

Now, something to think about: If the PC actually opened the throttle quicker then vehicles with one would be appreciably faster in the 1/4 mile. Using the nonsense numbers posted above, 2 extra seconds at full throttle would be a massive difference in total times for 1/4 mile. Don't you think the makers and advertisers would be screaming that info at you if it actually dropped, say, .5 second off your 1/4? Nobody credible is making that claim to actually being faster. Why?

The *only way* a PC could actually make the truck faster is if there was a decision being made at the accelerator position sensor. Say the voltage could only rise so fast, as opposed to feeding the true position to the ECM. If the ECM is what is retarding the throttle opening, and everything I can find says that's the case, then something between the position sensor and the ECM can't influence that. It can only "lie" about the position of the throttle. And, again, if it could actually make the throttle open quicker and the truck can benefit from that then you would note appreciable gains in 1/4 mile times at WOT.

I'm talking about the delay between when the pedal was pushed and when the Truck starts to move. I NEVER said it was a race car but it should start to move when the driver tells it to NOT when AI decides it's time.

Like you push the pedal and the truck just sits there for a few seconds not moving at all? That's a problem with your truck. Like your specific truck, take it to the shop. Like you push the pedal and it starts slowly moving? That's a small emissions laden diesel waiting for turbos to spool up. Just the nature of the beast, hence my suggestion to two foot it if you need to step out in a hurry.

I step on the pedal for my 2021 PW and it moves. I step on the pedal for my former/now my son's 2012 1500 with the 5.7 and it moves. I step on the pedal for my 6.2L Camaro and it *moves*.

I test drove a 2021 PW with a Pulsar with the adjustable throttle response and completely don't buy the hype. Yup, you can make it more touchy or less touchy but I can do the same with my foot/feet (and hand when driving the manual Camaro).

I'm familiar with search engines, thanks. That's how I know catbacks are good for 25hp and stickers are good for 5hp each.

You can't replicate a throttle controller with your foot, no matter how hard and fast you stomp on the pedal. You don't believe they work and that's fine. People once thought the earth was flat too.

I mean, we all knew about stickers. That's been settled science for years. But magnets? Honestly new information to me. Really makes me reconsider my reluctance to purchase an EV. I just wish I had the technical know how for a level 3+ kit.

I can't replicate a throttle controller, correct. I cannot increase or decrease the granularity of my pedal's response by pushing some buttons. What I absolutely can do is launch easier or harder, as I choose, by being an active driver.

Here's some facts I think we all agree on:
PC does not claim to increase HP.
PC does not claim to increase 1/4 mile times.

Would "opening the throttle sooner" not increase 1/4 mile times? Of course, the vehicle would be faster during that X.X seconds it was at full throttle vs partial throttle. If it's not, it just "feels more responsive" and isn't actually "more responsive". This would be easily measurable and verifiable. Higher power numbers coming on earlier, fatter area under the power curve. Yet none of the manufacturers claim that increase, why? What other aftermarket "performance" product doesn't tout any possible power gain? Why do guys buy CAI? Largely because they believe the hype claims of power gains without realizing it's in an ideal world with supporing mods.

PCs absolutely work for what they are actually advertised for. Pedal sensitivity adjustments. Nothing more, nothing less, despite the internet claims of throttles opening faster to turbos spinning up quicker.

You can "nuh-uh" all day, but so far there's no explanation as to how it works beyond "trust me". Curious which you believe is a harder launch:
1) Stock truck floored off the line
2) PC truck set to whatever
3) Stock truck 2 foot lauched at a moderate rpm...

I know in either hemi equipped truck I can break the tires free with my dumb ol' stock pedal without much effort. But I have secret stickers, so it's not really fair.

Maybe the fact that it opens so fast the tires spin which does nothing for 1/4 mile times.???
Have you ever driven a vehicle with a PC? I had one and it does work.

If you're already traction limited then what's the point? Gonna slap slicks on it? I mean, other than @Wild one

I mentioned up thread I test drove a truck with a Pulsar. Same concept, just gives you more functionality in that you can also set tire size. I have not driven a vehicle with the Pedal Commander brand, though.

They do work. As sensitivity adjusters. If they work to actually make it faster, numbers shouldn't be so hard to come by and the manufacturers would advertise them as such. Absent that, it's all just feels. Which is fine, feels are important. If I'm wrong, numbers should be easy to show. I've been wrong before, but I approached this topic with an open mind when I first became aware of them and nobody has yet to provide the answers to the logical questions I've posed any more than they have in this thread. You just get double speak (it makes it quicker but not faster), complete nonsense (it can remap shift points), and feels. Feels tells us louder exhausts are faster.

I've repeated myself enough, I think, so unless anyone comes up with hard facts I'll see myself out.

Nobody has ever proven they'll make your truck faster,as the throttle blade only opens to roughly 75% no matter what you add to the pedal control.If i was going to pick one,it'd be the Banks Pedal Monster as it won't kill you if it goes into fubarr mode.

I think that's the real issue. Anyone who has had one doesn't need to be convinced they work. If they'd bother to watch the video I posted a link to they'd see there is proof of that. There are lots of videos out there if anyone is interested.

Turn on large fan...face large fan...**** into it. This is tantamount to trying to convince the PC crowd that these things do NOTHING to improve performance because THEY CAN'T. Hell, when I challenge them to explain it to me, they can't even see my challenge for the sarcasm it is. They worship at the ground of the PC magic...You ain't gonna change their minds with logic.

You're not far from a couple dragstrips,you should take your truck out and prove the guys who've actually track tested the throttle boosters that they're wrong.Lots of guys on the hi-po facebook pages have ran them back to back and never found them to make a truck faster. That video you posted a link to,leaves a whole lot to be desired,and i'm not so sure how accurate they are using a stop watch,now if you find an actual dragstrip test that proves they make a differance,that i'd be more inclined to believe,over a guy on a back road using a stop watch,hell the least they could have done was use a Draggy to get more accurate results.If you don't know what a Draggy is,google it.

I'm all for having a healthy discussion, but keep it civil please. Sounds like you're on the edge of losing it with this post.

Who said anything about pedal controllers improving performance? Improving throttle response doesn't improve performance. They just help you to better use the performance you already have. In the end it's very simple...you don't believe they do anything, don't buy one. :cheers:

I have a pedal/throttle booster from BD Diesel since March of this year and haven't had any issues. And I'll tell you what, as soon as it was installed per instructions, noticed a huge different in response when I hit the gas pedal.

rick phillips · Nov 25, 2022

Appx. 3 yrs. & mine has given no warning lights, limp modes, nor codes, if it had I may feel different, but it would sure be hard to go back to the old sluggish feel I dealt with for first 2 yrs. I owned it. My 2013 4X4 4cyl. Taco is the only auto I've driven with a TC (Throttle Controller, not Turbo Charger), only auto I've owned that needed it. I drove it a couple of yrs. and very disappointed every time I drove it. After much research, investigating, and reading "reviews from places other than the Co. trying to sell them" decided to buy one. I decided to go with the Sprint Booster as it had a full, 30 day, no question asked return policy. Took appx. 30 min. to install and on first drive I knew it made a huge difference in driving my little 4X4. Been tickled every time I'm out in it. For the folks that don't want nor need one, don't get one, I wouldn't have got one if I'd been satisfied the way it was. For the folks that don't like the sluggishness of their FBY system, It's hard to imagine how you could be disappointed with one.
