BMW M3 E30 ECU 0 261 200 055

Brand new development from Specialized ECU Repair, we have researched and re design the old and unreliable ML3.1 DME. Our years of experience rebuilding the old design allow us to understand it’s weaknesses and benefits.

Our design benefits from 99% of SMD/SMT ” surface mounted devices” installed on the board also metallized thru holes for guaranteed reliability and no future cold solder joints. Using SMD/SMT components makes our new design perform much better than the original DME by better handle of current and temperature allowing the engine to operate much better with better injector and spark control.

Our new DME allows for the replacement of factory chips or “Eproms” allowing you to install your favorite performance Chips! 100% compatible with your BMW E30 M3, plug and play, no modifications necessary.
