How to Turn Off MDS on a Dodge Challenger
To turn off the MDS (Multi-Displacement System) on a Dodge Challenger, there are a few different methods you can try. Here are some options based on the search results:
1. Switch to Auto-Stick Mode: One method mentioned in the search results is to switch to Auto-Stick mode. When the transmission is in Auto-Stick mode, the MDS is deactivated. This means that the MDS will not engage, and all cylinders will remain active. To disable MDS using this method, you can leave the transmission in fifth gear, and it will shift up automatically.
2. Use Paddle Shifters: According to a forum post, using paddle shifters in a Dodge Challenger should have the same effect as being in Auto-Stick mode, meaning that the MDS will be turned off. However, it’s important to note that this information is based on a user’s personal experience and may not apply to all models or years of the Dodge Challenger.
3. Use a Tuner: Another option mentioned in the search results is to use a tuner device. Tuners can provide various benefits, including the ability to turn off the MDS. By using a tuner, you can reprogram the vehicle’s software to disable the MDS function. However, it’s important to note that modifying the software of your vehicle may void your warranty, so proceed with caution.
It’s worth mentioning that the effectiveness of these methods may vary depending on the specific model and year of your Dodge Challenger. It’s always a good idea to consult the vehicle’s manual or reach out to a certified Dodge dealership for more information on how to disable the MDS system in your specific vehicle.
