Got this MS3 Mini running my Miata and it performed flawlessly. Upgrading to the MS3 Pro to support more sensor inputs for my turbo build, so this one has to go.
What it is:
The MS3 Mini is a compact, full-featured MegaSquirt 3 ECU in a plug-and-play format. Runs sequential fuel and ignition This is v1.0 and does not support sequential ignition, supports boost control, flex fuel, wideband O2, and more — all tunable via TunerStudio.
Why it’s great:
• Full MS3 feature set in a small package
• Plug and play for NA 96-97 Miata
• Battle-tested MegaSquirt platform with huge community support
• TunerStudio compatible
Why I’m selling:
Moved up to the MS3 Pro for additional sensor inputs on a turbo build. This unit did exactly what it was supposed to do.
