Speeduino mk2.5 NBfl (2001-2005) v3 ECU

⚠️ LAST UNITS ⚠️

Plug & Play ECU for Mazda MX-5 NA (1.6 / 1.8vvt)

Simple, reliable solution for basic setups

✔️ What this is for:

- stock or lightly modified NA engines
- users who want full control over fueling and ignition
- engine swaps (e.g. 1.6 → 1.8vvt)
- simplified engine bay (no MAF)

🔥 What you get:
- quick installation (plug & play)
- full tuning capability (fuel & ignition)
- compatibility with common upgrades (injectors, coils)
- improved flexibility compared to stock ECU

⚠️ Important limitations:
This ECU is not intended for:

- turbo / supercharged setups
- highly modified or experimental builds
- users without basic understanding of tuning
No built-in knock control — proper tuning is required.
