Performance programming for additional power (gains vary by vehicle)
Torque management reduction or removal
MDS (cylinder deactivation) delete on Hemi engines
Gear ratio and tire size correction
Transmission shift points and shift firmness (TCM tuning where supported)
Electric fan temperatures (where applicable)
Idle speed
Rev limiter
Top speed limiter removal
Check engine light / trouble code adjustments
Other features may be adjustable depending on your vehicle and how it is equipped. If you have something specific in mind, email us before ordering.
SKIM (immobilizer) SKIM deletes are not available for vehicles with keyless push-button start.
Select your option when ordering:
Email Tune: You already own an HP Tuners interface. Email us your stock HPT file and we'll send back a custom tune. For 2015+ vehicles, your PCM must already be unlocked by HP Tuners. 2018+ vehicles also require the HP Tuners Smart Access Cable to read and flash in the vehicle.
Mail-In, 2014 and older: Send us your computer and we'll program it and ship it back ready to install.
Mail-In, 2015 and newer: All 2015 and newer FCA/Stellantis PCMs are locked from the factory. Your PCM must be sent to HP Tuners for their unlock service before we can tune it. This option includes the tune, the HP Tuners unlock, software licensing, and shipping to and from HP Tuners. Expect 10–14 business days total turnaround. If your PCM has already been unlocked, choose the 2014 and older mail-in option and note it at checkout.
Not supported: Diesel and Dodge Viper.
Important:
On 2015 and newer vehicles, PCMs with broken locking tabs or connectors cannot be unlocked and will not be accepted.
Send only the computer. Do not include brackets, rubber isolators, or mounting hardware, because they may not be returned.
If the PCM is not the original to your vehicle, let us know before purchasing.
Tuning does not repair mechanical problems. If your vehicle has an existing misfire, lifter tick, or trouble codes, have it diagnosed before ordering.
How it works:
Complete the order form and purchase. You'll receive an order number.
Email tune: Email your stock HPT file to evan@ewaltsautotuning.com with your order number.
Mail-in: Include a printout of your order email, or a piece of paper with your order number, VIN, and contact information. If you want any additional modifications done, include them in the notes at checkout and in the box. You are responsible for shipping to us; we do not provide a shipping label. Pack the computer well and send it to:
Ewalt's Auto Tuning
508 3rd ST SE
Watertown, SD 57201
We'll ship the computer back to you, ready to install.
Policy:
No returns or refunds once the service has been purchased.
If your PCM arrives damaged, has broken locking tabs, or is not supported, we will return it and refund the service minus return shipping.
If you have questions or want to go over your build in more detail, email evan@ewaltsautotuning.com.
