You have the latest Dimsport tool. You have the pinout diagram. You connect everything, and… "ECU not responding". This is the #1 support ticket for new users. Here is a checklist:
Problem A: Wrong pin numbering orientation.
Problem B: Missing secondary ground.
Problem C: CAN termination resistor.
Problem D: "New" security gateway.
Dimsport’s newer hardware reduces wiring errors:
Old way: Hold boot pin to ground, apply power, remove ground. New way (Dimsport): Apply power and ground FIRST. Wait 1 second. Then apply 5V to the boot pin for exactly 300ms. If you hold it too long, the ECU enters debug monitor mode instead of flash mode. dimsport ecu pinout new
Fix: Use the Dimsport harness adapter; it has a built-in relay for boot timing. If making your own, use a momentary switch.
