Workshop Technical Guide
Bench & OBD Power Supply Standards for Safe ECU Programming
Why voltage drops below 12.2V cause sector erase errors and how to set up a rock-solid 13.8V / 28V tuning bench.
Workshop Engineering Brief
For desktop Bench/Boot Service Mode reads (EDC17, MD1, MG1, DCM6.2, SID208), regulate a clean laboratory DC supply at 13.5V-13.8V (3A-5A limit) for 12V ECUs or 27.6V-28.0V for dedicated 24V heavy-duty truck harnesses; for in-vehicle OBD writes, use a 50A-100A showroom charger.
