Exact Match Data

Tuning data
built for your
exact set

Every set of Excess Injectors ships with the Exact Match Data — giving you the precise testing and matching data measured on the injectors in your hands, not a generic spec sheet. Load it, drive it, and run your set at its full potential.

How it works

Load the file. No trimming required.

Every set is tested

Each injector is run on our test bench and characterised individually, so its real behaviour — not an assumption — is on record.

Data made for that set

The Exact Match Data generates tuning data from how your specific set performed. No two sets share the same file — each one is unique.

Download & load

Load the file that matches your set into your ECU software. Trimming is already built into the data, to save you dyno time.

Worked example

Rated 1000cc. Matched at 943.

A set sold as 1000cc won't all flow at exactly 1000cc — and pretending it does costs you accuracy. Excess measures what your set actually flows.

If your set is tightly matched at 943cc, you download the 943cc data. The dead times — the time the injector takes to fully open and close — are carried across to match your set too.

That's why the data drops straight in: it is EXACTLY MATCHED to the injectors you are holding.
