One platform for 17+ years: NA, NB, NC, ND. Factory-ECU calibration, the 2.5 swap, turbo conversions, standalone. 1500+ MX-5 dyno pulls logged, up to 450 hp — and remote tuning that reaches any garage in Europe.
Standalone territory: MegaSquirt MS3, MaxxECU, ECUMaster. Our measured NB builds run to 450 hp / 500 Nm on a built 1.8, and a stock-internals 1.6 turbo made 170 hp.
Our main line. Factory-ECU tuning via MazdaEdit, the 2.5 L5-VE swap (183–236 hp NA), and the MX-5 NC turbo kit up to 380 hp.
Stage 1 measured: 1.5 from 131 to 154 hp. Honest expectation setting — the ND responds, but the margin is smaller than forum legend suggests.
Every row is a real car, before and after on the same in-house dyno. The full 86-car database across 20 brands is on the dyno page.

Reading it honestly: the 450 hp NB is a fully built engine. A straight 1.8 → 2.5 swap lands at 183–221 hp. A stock NC 2.0 Stage 1 lands at 177–190. We tell you which band your car is in before you pay.
Most of our MX-5 work never sees Athens. The loop: you send the stock ROM (MazdaEdit, EcuFlash — we tell you the cheapest route for your car), we send a calibration written against your VIN, you drive the log profile, we revise until the log is clean. Revisions are in scope, not billed per round.
From €450 + VAT (€558 incl. VAT). The full remote process is here — and if your engine is a fresh 2.5 swap running the stock 2.0 map, that calibration is not an upsell, it is the job.
The L5-VE 2.5 from the Mazda 3/6 into your NC: 183–236 hp naturally aspirated, 225–290 Nm, measured across twelve swaps. Four ways to buy it — DIY kit, trade, fitted from €3600 ex VAT. Part numbers, the three mechanical traps and the automatic-donor gearbox issue are all in the DIY guide.
Measured turbo builds: NC 1.8 to 275 hp, NC 2.0 to 370 hp, 2.5 turbo to 344 hp on the kit, up to 380 hp. The DMS turbo kit page covers 1.8, 2.0 and 2.5 Duratec applications.
Because the failure modes of this chassis are known here, not discovered on your car. We know the NC ECU flashes clean over OBD — no bench, no soldering, no cut loom. We know the 2.5's oil pan fouls the subframe and the donor pulley has the wrong tooth count. We know what a tired NC clutch does at 270 Nm. That knowledge is the product — the dyno just proves it.
Every calibration is issued per VIN and archived with your stock ROM. No VIN, no tuning.
Yes — that is most of our MX-5 work. Stock ROM + datalogs in, per-VIN calibration out, revised from your logs until clean. From €450 + VAT (€558 incl. VAT).
All four. NA/NB on standalone, NC on the factory ECU, ND Stage 1. 1500+ measured pulls, up to 450 hp.
Measured bands: NC 1.8 Stage 1 → 139–159 hp · NC 2.0 Stage 1 → 177–190 · 2.5 swap NA → 183–236 · NC turbo → 270–370 · built NA/NB turbo → up to 450. We place your car in its band before you pay.
DIY kit €2600, trade €1700, fitted from €3600 — all ex VAT, calibration included in the fitted package. Full ladder on the packages page.
Yes — swap kits, headers, cams, turbo kits, with shipping quoted by destination and calibration done remotely.
