Pedal Commander! Awesomeness!

thanks for posting. Do you remember what the P/C was set to when this happened? My guess would be the truck was trying to throttle up and maybe P/C turned that signal into something way more than practical.

I mentioned this in my facebook post otherwise I never would have remembered--I changed from -2 city to +2 city a few hours before the big surge happened

Y’know... In the first week I was testing mine, I posted about an rpm hang.

I put the truck in sport and the P/C in sport. The truck stuck in the 3-3.5k rpm range or higher no matter how much I slowed until I was slowed below the 2k rpms downshift point for sport mode on the truck but you don’t get going that slow. I could not compel the truck to upshift at all.

The truck tries to keep you at about 2k rpms or higher in sport mode, but the p/c on sport in my truck almost made the throttle binary. touch the gas and you had about half the available boost. I think I tried city+2 as well and ended up dialing it back.

I’ve never had a surging incident though.

Did anyone at PC ever respond or did you contact them?

That's a pretty serious claim, to say the least.

IIRC there wasn't a whole lot of response from them.

PC said they would get us proof, then kept coming up with excuse after excuse for not providing testing info. About the time PC claimed they weren't able to get the info due to a language barrier, and no one seemed to care because they were too caught up in the circle jerk I think most of us just moved on from the issue...

That sucks, really sucks.

An ETC system consists of three components: a gas pedal (TPS), a throttle valve that is opened and closed by the electronic throttle body (ETB), and an engine control unit (ECU).

The ECU runs software to determine the required throttle position from data coming from the TPS on your gas pedal, engine speed sensors, and cruise control switches (if applicable). The electric motor is then used to open the throttle valve to the desired angle via a closed-loop control within the ECU.



Pedal Commander is very simple, it speeds up the signal sent from the TPS to the ETB, which is then sent to the ECU to determine how much to open the throttle valve (dependent on which mode you're in). BUT this is only in effect when the TPS is being actively used AKA when pressure is being applied to the gas pedal. If the pedal is stationary at 0% (such as when you’re coasting, applying the brakes, using cruise control, etc) the Pedal Commander has absolutely no effect on anything to your vehicle.



Failsafes: All vehicles with TPS have a 'limp-mode'. If something within the electronics fails, (say the TPS and the ECU are not talking to each other in a way that they can understand) the ECU shuts down the signal to the TPS and a set of springs in the throttle set it to a fast idle, fast enough to get the transmission in gear but not so fast that driving may be dangerous.

This is active in ALL vehicles, with or without Pedal Commander. If it becomes unplugged, you go into limp mode. If the sensor gets fried, you go into limp mode. If the electronic throttle body is unplugged, you go into limp mode. If the ECU is unplugged, you go into limp mode.

It is no more dangerous than running out of gas.

As promised, I've attached our current CE certification for Pedal Commander. The product has been tested and is completely safe for use. It's in Turkish, as that is where the product is manufactured.

Turkish..... most excellent!

I wasn't going to respond but the posting of this Certification has opened the door.

CE Certification excellent! This provides zero credibility. Pretty much a self certification saying you did testing. Doesn't say the type.

Lets see testing to Automotive specifications. I'll help you out.
ISO-11452-2
ISO-11452-4
ISO-11452-9
CISPR25

All the systems including the TPS, ECU, ETB all have to conform to these specifications and are highly scrutinized before being implemented. These test cost hundred of thousands of dollars from Design to placement in the vehicle. I would venture to say that a part that cost $300 has 0 credible testing.

I would think that any system that is controlling that signal should be tested to these same standards as well.

Why should you be concerned? A company I work for makes a piece of equipment that is almost exactly the same. It tells the ECU what the % of ethanol in the fuel is. It doesn't pass any test, and these are real world RF Tests. The difference is the engine really doesn't care if there is a 10% (The amount the signal can change before failure) change in ethanol content.

You are going to know 10% change in throttle to the ECU and that is our threshold point, at max real world (ie. Radar Array) it sends it to 100% duty cycle or 0. That is WOT or Nothing.

I can keep going but I think you get the point.
