Review on 🚀 Increase Performance & Fuel Efficiency with Mazda MX-5 Miata Performance Chip/Power Programmer - Compatible with 1.6L, 1.8L, and 2.0L Engines! by Adam Boudreau

Just received and NOT installed - still debating. This is NOT a programmer for your computer - it just changes the output of the sensor. your wiring harness! They offer a crimp on splices, but they often cut off some of the strands of wire and sometimes cut the wire completely. So if you decide to remove it later, you'll have bare wires that you'll need to wrap with tape, which can be partially or fully cut so they can break. This may work well, but not what I was looking for. I would MUCH prefer a plugin. I'd like to see if I can find additional sensor connectors so I can make an adapter cable, but I think I'll just send it back.
