Throttle Response Controller, 9 Drive 9-Mode Smart Electronic Racing Pedal Accelerator for Toyota 4Runner Tundra Land Cruiser Prius Camry Corolla Lexus GX 460 (809)

What's more frustrating than a truck that is tough to get good mileage with? The truck feeling sluggish because the vehicle manufacturer decided to write code into the ECU to keep your gas pedal from going when you push it. Granted, the designers put much work into the torque management system to help keep the mpg's somewhat under control when you're making 400hp these days in half-ton trucks. So, driving my Ram under normal conditions, the mileage is halfway decent. I just hate the pedal lag. Most reports I've witnessed after people have used the "pedal commander" type of tuners are very happy results. I just couldn't commit to the cost. When I ran across the review of a 9-Drive device, I realized huge cost savings with it. I jumped on Amazon and ordered the 809, which works with Gen 5 Rams. When it arrived, I couldn't wait to install it. The device is small, making it easy to find a mounting point, but it's not too small to make quick changes. I installed the device in maybe 35 seconds. Full disclosure I looked at a video before starting. Basically, you unplug the connector that attaches to the gas pedal and install the provided pigtail in series. The button feedback is nice and easy to understand. You can operate normally without anything added from the unit, all the way up to several levels of race mode. Point of clarity, you won't make your truck more powerful, the device just adds voltage to the ECU depending on throttle position. With a throttle-by-wire system that most cars now have, the gas pedal position is determined by a sensor. The sensor relays that position for the ECU by verifying a voltage output. For instance, if the pedal is at idle, the sensor sends 0v to the ECU. At full throttle, it will send 5v to the ECU and varying voltages in between. The ECU will then open the throttle body based on the voltage determined by the ECU. The engineers take that voltage and filter it a bit, requiring more of a pedal "push" to increase the voltage, producing a lag feel at your foot. Older carbureted engines don't have that lag because the throttle is mechanically connected to the carburetor, so the carb opens at the same rate the gas pedal moves. Here's where "pedal commanders" work. They take the voltage reported by the gas pedal's position and add different voltage levels (depending on the device setting), and the ECU "thinks" the pedal is being pushed harder. The changes made on the 9-Drive take instantly and can be changed as you drive. I can't compare the 9-Drive to a competitor since I have used others. But for the price, it does exactly what I expected from a device of its kind. Word of caution, It's fun, very fun. And your gas mileage will not like it. I enjoyed the highest level of race mode, which feels like a well-tuned carburated hot rod. But after watching my average mileage drop a couple of points, I changed to a mid-range setting. To me, that's the sweet spot. It has made the truck much more responsive, but only lightly affected my average mpg's. Very happy customer.

Definite difference, quick plug and play, did it in less than 3 minutes. I have not had a bad problem with it, it works really well and I have been playing with it. The economy mode is my favorite as of right now and having p3 on and sports mode at 9 is a crazy mixture.

It works and fits for my 2021 Laramie, definitely makes it quicker in a sense. If you want it faster off the line this will do it but as far as actually giving you more power overall it doesn't give you horsepower just quicker throttle response. If you put it into sport mode the response of the pedal is crazy, you could fart the pedal and your truck will still squawk tires. I leave it in the eco mode on 2 and it's sill squawks tires every once and again.

This is an awesome product! Have seen similar products advertised for years and assumed they were a gimmick. This is definitely NOT, 15 minutes to install and immediate results the first time you hit the pedal. Makes driving my Jeep Wrangler even more fun to drive. I never understood why my wife’s SUV with a 4 cylinder engine would jump off the line from a stop while my Jeep would slowly get up to speed. Turns out it was the factory set up of the accelerator and this product corrects that and gives you the ability to easily change to your driving style and driving conditions. Excellent price as well, those other products I see advertised cost over five times what this cost. Would definitely recommend this to others and give as gifts.

I wanted to get better response and it did ramp up the sensitivity of the throttle but I like the economy mode so it’s not so quick to run up on someone.
