Tuning DOES NOT fix mechanical issues or misfires. Tuning is for vehicles that are already in good running condition. Tuning is for making aftermarket parts work properly together.
The short answer is we provide you a tune via email. The long answer includes you getting to have some fun in your car. Have you ever wondered how E-Tunes work? The following information will provide you will all the ins and outs of how E-Tunes work. With this knowledge, you can confidently purchase an E-tune and start getting more smiles per gallon. Once you purchase an E-Tune we will email you your first revision along with detailed instructions to complete the E-Tune. The instructions include everything from loading the tune to your Accessport to performing data logs. All you have to do is send us data logs, we then review them and send you a new revision. Rinse and repeat until the tune is complete.
E-Tuning is a great way to get a custom tune without getting on a dyno. A dyno simulates road load. Since it does that we can accomplish a tune without putting your car on the dyno with the logs you send us. E-Tuning does not replace dyno tuning and is not a less expensive option than dyno tuning. A dyno tune will always get you the most power and the best driving tune. With that said an E-Tune will still get you a well-performing and reliable tune. If you don’t live near a dyno facility an E-Tune is a great choice.
Running the Cobb OTS maps can be a great option for some people, the only downfall is they require Cobb only parts. If you have/want to run different brand parts or once you are modified beyond their staged tune specifications you need a custom tune. Since all of our E-Tunes are custom to each car, we can get you a smooth running and well performing tune for your exact mods. We have years of experience dyno tuning the 2015+ WRX and know exactly what to do when tuning to give you the best driving car.
Tuning DOES NOT fix mechanical issues or misfires. Tuning is designed for vehicles that are already in good running condition and designed to make aftermarket parts work properly together. If you are booking a tune because your car is running poorly that will need to be addressed before we can start the tuning process. Check out our Pre-Tune Checklist for more information.
If we run into mechanical issues while tuning, the tuning will be paused until mechanical issues are fixed. We tune these cars all day on the dyno and know when parts are performing as expected. 9 times out of 10 when we have issues, it’s a mechanical issue and not related to the tune at all. If after a few revisions the car isn’t responding as it should it will be up to you to either diagnose and repair the problem or bring the car to a reputable shop that knows how to diagnose and fix issues on these cars. We can only help you so far over the internet.
E-Tuning revisions and log reviews are done Mon-Fri 8:00 am-4:00 pm (CST). E-Tuning is not available on the weekends. You are welcome to perform your logs in the evenings or weekends and email them to us. We will review them as soon as possible during our open hours and send new revisions. Depending on the time of year and how busy we are, you may receive your tune revisions in a few hours up to 48 hours after the data logs are sent.
Times are changing. To keep the aftermarket performance industry alive and following Cobb’s “Project Green Speed”, we can not disable any check engine lights while Tuning. That means we cant tune your car if you have TGV or EGR Deletes. If you have any questions or are unsure if we can tune your car, please contact us at firstname.lastname@example.org
We CAN still tune E85, Upgraded Turbos, Fuel Injectors, Fuel Pumps, Intercoolers and more. These updates really only remove the ability to turn off check engine lights and flex fuel. We already off a new version of flex fuel, that works with the latest Cobb Green Speed updates, for the 2015+ WRX and more models are soon to follow! Check our Blog for the latest updates.
