A blank AutoCal V3 for an agreed tuning setup
Choose this EFILive AutoCal V3 when you need the device without preloaded tune files. Before ordering, confirm that your vehicle and chosen tuning provider can use the device for the work you have planned. Buying a blank unit does not supply a ready-to-install calibration.

Blank device or a tuning package?
The blank device makes sense when a tuning provider has already confirmed the required hardware and file arrangement. If you need both equipment and a calibration, ask JS Speed Diesel about the relevant Duramax or Ram Cummins package instead. Verify the engine, model year, required licensing and provider compatibility before choosing either route.
Pre-order checklist
- Confirm that AutoCal V3 is the device your tuner requires.
- Establish who will supply and support the tune files.
- Check which additional licences, equipment or services your setup needs.
- Make sure you are ordering a blank unit deliberately rather than expecting preloaded tuning.
Delivery and returns
The listing asks buyers to allow 3–5 business days for processing and shipping. Confirm current timing if you have an installation appointment. AutoCal devices are final sale, so settle compatibility questions before placing the order and review the store's current shipping and purchase terms.
Common questions
Can I use the device immediately as a complete tuning package?
This product supplies no preloaded calibration. Arrange the appropriate files and any other requirements with your tuning provider first.
Does this purchase include JS Speed Diesel tune files?
No. This is the blank-device listing. A package that includes tuning must be selected or arranged separately.
Can I return it if I choose the wrong device?
The stated policy makes AutoCal devices final sale. Confirm compatibility before ordering.
