Choosing Between Plug-In and Wire-In ECUs

If you're building a high-performance vehicle or upgrading your stock ECU, Link Engine Management offers one of the most versatile and reliable tuning solutions available. But with options like Plug-In and Wire-In ECUs, how do you choose the right Link ECU for your project?
