Volvo Truck Diagnostic Software Tech Tool vs. Dev2tool vs. Visfeed

What is Volvo Premium Tech Tool, Dev2tool, Visfeed and How to use them for Volvo/Mack/Renault/UD trucks diagnostics and programming.



Volvo PTT Premium tech tool: for diagnosis

dev2tool: for programming

Visfeed: for reprogramming



For details, here you go.


What is tech tool:


OEM Diagnostic Tool. Premium Tech Tool (Volvo PTT) is a Windows-based diagnostic application specially designed to test, calibrate and program engine parameters.


  • Read / Interpret Fault Data
  • Extensive Diagnostic Tools
  • Facilitates Update Process
  • Clear all diagnostic trouble codes including emissions related ReGen codes.
  • This software will communicate with trucks below, with the proper interface device like Volvo Vocom 88890300 or Volvo VCADS


Volvo Trucks (Older electrical system, Vehicle electronics ’98, VERSION2, VERSION3, VERSION4)

Note: the latest Volvo Tech Tool: version 2.5.86

What is dev2tool:


  • Special tool to access and program parameters at any level without restriction;
    • Used primarily for program: speed limit, change CHASSIS ID, immobilizer neutralization;
    • Change minimum / maximum values of parameters, for example: increase speed limit;



with dev2tool, you have access to all levels(specially level 2) parameters

Dev2tool will give you access to over 11000 parameters! This is correct!
The only problem is that you truck DOES NOT have 11000 parameters.
I got dev2tool and I’ve tried to disable the egr on a 16L volvo engine (volvo D16D US model).
As I said with dev2tool you will see for example a parameter called “EGR Axis” but the ECU on the truck DOES NOT have that parameter in any programming levels.
Pretty much is not possible to disable unless you will find somebody (tuning company) that can reprogram your whole dataset on the engine ECU.


Note: the explanation of the parameters for Volvo trucks


That parameter HJM (level 5) it is only into PTT database. The ECU on Volvo trucks (US Model) does NOT have that parameter.
Anyway even if exist is not possible to change it because it is level 5.
You can change the value of that parameter but when you turn on the engine it will get back to it’s original value.
Level 5 is only function test, freeze frame data ….
I’ve tried already some level 5 to reprogram but NOPE … not working.


Note: Dev2tool for Tech Tool for parameter programming on new trucks FM4/FH4

Some of option
• Chassis ID Change.
• Immobilizer ON/OFF.
• Injector programming.
• Speed Limit programming.

What is Visfeed:


  • Small Database Flash files.

It works as a Special tool to encrypt/decrypt/edit intermediate storage files for ADVANCED Volvo Trucks Diag users.
With this tool you have this interesting options:
• AdBlue OFF.
• Convert EUR3 to EUR5.
• NOx Torque Reduction OFF.



The Tool is made to make all file rebuilding process as simple and easy as possible. It also allows to view ECU file and other information of part and sub part numbers, parameters, PID, PPID, SID, PSID, FMI. Checksum calculation possible of Intel HEX line and whole CSW file. For portability USB key included
