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 944 2.5, plug and play, no modifications necessary.

Medium size Phillips screwdriverMedium size Flat screwdriver
Start by pushing the passenger seat back as far as you can, remove the floor mat. The carpet is attached at the top with Velcro. Pull the carpet back to locate the protective wood foot board. The foot board will be held by 4 Phillips screws and washers, remove and set aside.
The DME/ ECU is attached to a supporting metal frame, locate and remove the 2 Phillips screws at the bottom of the frame and the 2 plastic screw retainers that secure the metal frame. With the frame released from its location, gently pull it back; then locate and remove the remaining 4 Phillips screws that hold the DME / ECU against the metal frame. After releasing the DME / ECU from the metal frame, carefully remove the main connector by pushing the silver tab on the side of the DME and carefully pulling the main connector.
