INFO ON GM ECU MODE 2 AND 4. EPROM DUMP AND MESSAGE SENDING. TUNERPRO
I am working with A GM ECU through Tunerpro. I have established communications with mode 1 for diagnostic chit chat. I would like to execute an EPROM dump with mode 2. Wondering if anyone has done this with Tunerpro?
Also, I know the ECU I am working with (diesel) supports mode 4 type functions where someone can reset the initial timing. I am not sure yet how to do this as there is not much info online about it. Does anyone know what I am referring to and how execute it?

Here is some Mode 4 info.
IDK what ECM/mask you are working with but will give you some idea how it works in this application.
I don't believe the current TP can output the string lengths needed.
Most times people are using custom written code to work with this.
