Looking for a reliable multifunctional adapter for both diagnostics and chip tuning. Compatibility with both modern and older vehicles is important — especially Toyota, Ford, and GM. Thinking of getting something with J2534 and CAN support. Mongoose-Plus ISO/CAN 3 caught my eye — seems universal and has a good reputation. Anyone here used it? Is it really worth the investment?

Used it with Techstream for Toyota and IDS for Ford — works like a charm. It's fast and stable. For older GM models, it also performs well, as long as you have the right calibration files. Just avoid cheap clones — they often have driver or connection issues.

If you're seriously considering the Mongoose-Plus ISO/CAN 3, I recommend checking out ECUTools. They offer only original tools with solid support, and their site is pretty straightforward. I got mine there, and the delivery was quick. Plus, they have other J2534-compatible options in case you're still comparing. Here's the link https://ecutools.eu
