Do I need the base VF Tuner kit to use this?

Yes. This is an upgrade package and only works if you already own the regular VF Tuner kit. Buying it alone gives you nothing to flash with.

Which cars does it support?

Mazda Skyactiv G petrol engines from 2012 on: 1.5L, 2.0L and 2.5L with Denso ECUs. It does not cover Skyactiv D diesel or older MZR engines.

How fast is an ECU flash?

VF Tuner states a 45-second programming time, so a full reflash takes under a minute. That makes iterating on a tune much faster than slow cable-based flashing.

Can I tune a turbo or supercharger build with it?

Yes. It adds custom code boost support and AFR EROM control so you can set fuel targets for forced induction as well as naturally aspirated engines.

Is self-tuning safe for my engine?

Only if you know what you are changing. Wrong fuel or timing tables can cause knock or engine damage, so datalog with the enhanced CAN logging and have a professional review risky maps.

The listing lists only the VF Tuner Pro Upgrade - Skyactiv G. It is a software upgrade, so expect a license or download rather than hardware.

Our take on the VF Tuner Pro Upgrade - Skyactiv G

The VF Tuner Pro Upgrade unlocks the full tuning suite for Mazda Skyactiv G petrol engines (1.5L, 2.0L, 2.5L, 2012 and newer) with Denso ECUs. It adds self-tuning access to maps and table parameters, custom AFR control for naturally aspirated and forced induction builds, boost support, and enhanced CAN logging. It is an upgrade only: you must already own the regular VF Tuner kit. No price was listed for this upgrade, so compare it against the base kit's cost before buying.
