The most effective way to read and program Delphi DCM3.7 or DCM3.7AP engine control modules (ECMs) is by using the PCM Flash tool. This tool allows you to work with these ECM types via the diagnostic port or in bench mode, without having to open the unit. 

Note:

While both methods are supported, we recommend bench mode due to its superior protocol stability. 



To read or program a DCM3.7 / DCM3.7AP ECM, you’ll need the following four components: 


   1.   PCM Flash tool

PCMFlash Dongle DCM3.7


   2. Tactrix Open Port 2.0

Tactrix Open Port Interface


   3. Universal ECU Bench Cable

Universal ECU Bench cable


   4. Cojali Cable (only required for diagnostic port programming)


Cojali Cable for Diagnostic


If you already own a Tactrix Open Port 2.0 or Universal ECU Bench Cable (e.g., for use with the BitBox Tool), you don't need to purchase these items again.
  

The Delphi DCM3.7 / DCM3.7AP ECMs are commonly found in various types of equipment, including:

  • Bobcat machines

  • Kioti tractors

  • Mahindra tractors

  • TYM tractors


If you're planning to perform a DEF/Urea/AdBlue delete, you'll also need to read, program, and modify the ACM (Aftertreatment Control Module). This must be done using Trasdata in bench mode.
