💻 How do we test ECM performance? Before shipping an ECM to another state or country, we test it intensively, including bench testing, verifying internal signals and voltages, and testing on our engines or trucks ✅🚛 We run it to normal engine temperatures and confirm there are no issues or active codes 🔍💻 This allows us to detect issues like misfiring cylinders or smoke that a simulator cannot easily show 👀 If you have questions about ECM repairs, you can leave them in the comments 💬 #Dies
