Best Answer:Hi Brandon, I'm glad to help you out. No. This item doesn't replace the ECU (engine control unit) of your vehicle. We suggest that you get the ECU of your car from the local auto parts store. For more maintenance parts, we have a sale on brake parts. Click this link to get one for your vehicle: <a href="https://www.carparts.com/search?q=brake" target="_blank">https://www.carparts.com/search?q=brake</a> I hope this helps. Happy shopping.
