Wztepeng 807 9 Drive 9-Drive Modes Smart Electronic Throttle Response Controller Pedal Racing Accelerator Compatible with Chrysler Dodge Challenger Magnum Jeep Commander Grand Cherokee Wrangler JK RAM

Plug and play install, very nice.Works as advertised, eliminates the factory delay in the throttle pedal.

This made a massive difference in the driveability in my 09 jeep jk. It has so much snap now that I can do burnouts in the dirt with ease. I keep the setting at 2.3 and it's still probably a tad excessive. I tried 2.6 but it was to sensitive for the throttle.It's easy to install unless you have a factory amp under the steering wheel. Then it's very hard to get your hands in deep enough to assemble the connector properly. Took about 20 minutes of twisting myself around to be able to get my hands and the harness in position to connect to the pedal assembly

This definitely makes a difference in your pedal response! I have to say I was shocked by this product and so far am pleased with it!

Bought this after another Crossfire owner sent me the link that this was what he purchased. Unit came with the harness in the picture, which does not fit the Crossfire. The Crossfire as a two row plug with three prongs in each row. The other owner said it worked great and received the correct connector, but without the plug/harness there is no way I can try it. I had a second one sent to exchange it thinking it was a mistake, but it too came with the wrong harness. Wrote the vendor, they didn't understand why it wouldn't work, no offer to find the harness, simply stated to return it. So I'm returning the original order and replacement.I even bought another unit from another vendor, with the same description, model number, and saying it fits the Crossfire. Same incorrect plug. Not sure how the other owner received the correct one, but three strikes (two with this unit) and I'm passing on the idea of using one of these now.I'm sure if it actually connected I would give it more stars. But since I can't plug it in, and the description is incorrect on the fitment, have to give it one. The box, packaging and look of the unit was nice though....

Installed on a 2011 JKU in conjunction with a trail dash 2 set to 91 octane. Jeep is on 35s with stock 4:10 gears and it made a huge difference in off the light acceleration, which you can feel right away when you installed. I also find my self speeding which I never had with the 3.8 minivan engine the jeep has. The factory setting on this was 2.6 but I did have to take it down to 2.3 which made it more drivable in traffic. I have used programmers that are supposed to do the same thing as the 9drive but they do not have the same effect as this unit. I do like being able to adjust the throttle once I hit the trail instead of reflashing the computer.

So the higher performance modes work great. It instantly increased throttle sensitivity for performance, but the eco mode doesn't seem to do anything in either vehicle(2015 ram2500 and 2020 ram1500). Installation took 5 minutes and was plug n play. I docked it for the eco mode. On eco, you can still mash the pedal to the floor and it feels like normal mode. Even when feathering the throttle in eco doesn't seem any different.

It makes no difference in the car, no performance or any advantage, it just improves your throttle sensitivity, after almost a week it threw my throttle light on and made my have weak acceleration. After that I just simply fixed the harness attachment and the light turned off. Overall, it's great other than the throttle light and harness coming loose. Simple fix! Hopefully it doesn't happen again otherwise I'm tossing it LOL

Great delivery - ease of use. - polished and attractive unit - worked as advertised
