Only used if we need to reach you about this order.

Vehicle or equipment

Required if you chose “Other”. Include displacement and any engine code.

Helps us match your file to the right controller. We never publish it.

Hardware and modifications

A calibration has to match the hardware that is actually on the engine. If something is stock, just say “Stock”.

Intake, exhaust, intercooler, tires, transmission work… write “None” if stock.

Knowing what is coming helps us leave room for it.

Emissions equipment currently on the engine (required)

Tick everything that is fitted. This tells us what the calibration has to work with.

Goals and use

Wheel or crank — say which in the notes.

Thin air changes how much fuel and boost an engine can use.

Primary use (required)

Symptoms, problems you want solved, how it is driven, deadlines.

Files

The untouched file read from your controller before any modification.

    If the controller already has a tune on it, upload a fresh read of that too.

        CSV or log files from a drive — up to 6 files.

          Review and submit

          Legal use

          Calibrations are sold for off-road, competition, or otherwise legally permitted use only. You are responsible for complying with all emissions and vehicle regulations that apply where the vehicle or equipment is operated.
