Convenient breakdown thanks to Pedal Commander?

Everything is electronic nowadays .great u have 50k in your ov tune .curious to see what actually happens to the components it affects in the long run . I’ll stick with what the engineers spent years designing and testing .Rather than ov tune that probably took like 2 weeks to slap together . Pretty sure ov tune doesn’t warranty your engine if something catastrophic happens and They make u agree to some discloser.

 

Mine will very occasionally flip on a check engine light and lose almost all throttle response. Turn the truck on and off once or twice and it’s back to normal, although it takes a bit for the CEL to go off. I scanned the codes and it was for a throttle position sensor. Fairly sure the pedal commander is making it mess up every once in a while, the sensor is fine. I’ll deal with it until I can get an HP tune, I can’t drive with out the PC on.

 

As others have hinted at here, I agree that it seems you got ripped off at the dealer, as the Pedal Commander would not cause that problem. it does nothing to the computer tune and only accelerates the response of the throttle butterfly. While I actually do NOT have pedal commander, I DO have the ORIGINAL and first throttle booster, the Sprint Throttle Booster. It is the original and works perfectly great. It does not modify anything but only increases the response to the throttle butterfly when you depress the gas pedal.

 

I've had the PC for 2 years and it's been great. Dealer actually did a good job getting me in quick on Friday at 5:00. I only had them clear codes and diagnose. Not going for throttle body yet

 

Could be the crank position sensor. Word is they had this resolved by now, but who knows. There's an updated part number and it's easy to replace yourself.

Engine Crankshaft Position Sensor
Part Number: 9091905098
Price:$82.73


Edit, I see you have a 2017, so could be this, thought you had a 2020

 

Thanks for the info

 

I've seen pedal commander do this multiple times, but usually it's when combined with a tune. I wouldn't rule out that pedal commander caused this.

You don't necessarily say what the brake error was, but I would bet it was "Brake Override Malfunction"

See attached if you would like to read more about it.

 

I personally never had trouble with OVTune. I took it to the dealership to have the tranny replaced and the warranty still covered it.

 

Thanks Karl, I even understood part of that

 

PC is essential a multi variable gain selector. It has a variety of settings that adjust the gain slope on throttle input voltage, which then adjusts how the throttle valve reacts otherwise normal throttle modulation. As someone already stated a throttle failure traceable to the PC would be present without the PC. The PC doesnt increase max end voltage, rather it adjusts the ramp of the voltage to the throttle valve.

I currently run a PC on my Tundra. On the more aggressive settings it is overly sensitive to input. I will go out on a completely theoretic limb and suggest that it may be possible if the setting were to aggressive and it was accidentally depressed too much while in a state of little load that it may send current to the throttle that may result in receiving a voltage that would not match the TV position, if the delay were too great between input and actual position then perhaps limp mode could occur due to a TPS issue. This still wouldnt kill the throttle valve though. If the TV were over current it wouldnt work regardless of the presence of the PC.

PCs seem to be a mixed bag, the majority of users seem to see little or no issues, but some people arent so lucky. I wont defend the product simply because I own one, there are some minor issues where it does surge due to little resistance (going over bumps) combined with an inconsistent pedal input on my end. That mostly results in me smacking the back of my head on the head rest though, never limp mode.

It sounds like the dealer did what we call "show action", which is to order parts to make it appear as though there were confidence and a solution in the presence of not actually knowing what was wrong. Its super easy to do when you charge another party for it, we dont even have guilt over it.

 

That's a helpful explanation thanks! And I run PC on City+2....never real high

 

The engineers spent maybe a total of 6 months “designing” the power train in the 3rd gen. Nothing was engineered properly, it’s almost as if they took bits and pieces from other models and Frankensteined them together. Probably explains why the fuel system delivers more fuel to one cylinder bank than the other. OVTune spent 2 years making the first iteration and it took another 2 years to get to the current iteration.

 

Had the same thing happen on my f150 EcoBoost. At least the 3.5L shared the same, unchanged, timing chain has its non-forced induction brother. Even stock, the chain would stretch over time causing start up clatter and eventually failure. Extra boost from a tune didn’t help and voided a ton of warranties. Heck, even showing the dealership the clatter would end with them saying it was within spec (clatter had to last for a certain duration).
