Depends what you call universal?
Since everything I create follows a specific command set which is publicly posted, although this still requires someone to be making software to integrate with.

A logger that prioritizes external sensors. And piggyback existing sensors, especially something simple as temp sensors. More universal with less work. Yeah, user has to splice some wires, big deal. I think an external tool which allows adjusting the priority of live data being returned would be th...

There has been a couple interesting finds recently. First one is being able to send data faster then a module can keep up with. This seems to have only impacted much older engine computers such as early Ford BA ECMs where if a data chunk is sent too fast, then the ECM actually misses the response an...

What I would recommend doing: 1) Make a bin file and manually defined what each table/parameter is stored in Tunerpro. 2) Copy your current arrays from your sketches into the bin (use AI for this, ask it to insert "X" array into the bin file at "X" offset. 3) After making your ed...

update: Looks like its easy to run ghidra on ubuntu 24 LTS. Just apt install python3 openjdk-21-jre openjdk-21-jdk then from an unzipped version of ghidra run it with ./ghidraRun Once its open create a project, import the bin file from the PCM and use processor type powerpc big endian 64 VLE/Alitiv...

Most brand new reads require people to purchase the parts and grab the reads using 3rd party tools. Sometimes people post them online on various sites, sometimes they are kept for person use only. Best bet is to search the exact part you are after online and see if there are any brand new file reads.

Ah yes, it could be implemented with J2534 to allow dual protocols at the same time.
This would basically just be implementing the multiple CAN functionality built into the firmware at that point.. so.. might as well add it if its capable of doing so.

Always exciting when working with a new generation of tools, since I can add in even more custom capabilities. Something that I have wanted to add but was unsure if it was worth while doing, was the ability to have two (or more) CAN protocols running at the same time on the tool. An example would be...

Yeah, we know him. That's forum member loud160 on this site (but mostly active elsewhere). He has also helped test pcmhammer and done some development on another popular interface and software product. Not sure if he wants to be the face of that but those guys can speak up if they want to. The hard...

Im assuming this is referring to a VT->VZ commodore cluster since those are ALDL based.
From memory.. they are a 512byte (0x200) eeprom size.
And also assuming he is reading the eeprom with an eeprom programmer, not via OBD.
