Playing around with the 2.7 software (ECU and TCU)

The speed control on it works though. Changed between max and min and it made a huge difference in the read times.

Guys, I have some OBD codes that appear to work for my 2013 JKU Wrangler with 3.6 Pentadtar. Maybe it will help but no guarantees with your vehicles.
Oil temp and Oil pressure mostly seem to work although we know the sensor is dodgey.
The info below was exported from Torque Pro to a CSV spreadsheet.

Thanks Old_Dog. Tried 2 of them today, but got nothing back. Could be something I did wrong though. Thanks anyway.

I can only imagine there would be some big differences between the old WG and everything else since.

Big differences! The WG is not OBD compliant. It was not law in Europe and Australia until 2005 (for diesel passenger cars). This is one reason why it never hit the US of A, where it was law. The WG happens to have some OBD bits that carry over from models that were OBD compliant.

Different note... Has anybody tried openvehiclediag? I'm not clear on what hardware is needed to try it.

Looks interesting. Seems to be a few videos linked to watch. They may explain it.

Found this comment though

"But in theory, it should be possible to run OpenVehicleDiag on nothing more than a Raspberry pi and $5 MCP2515 shield!

Also in the pipeline is experimental support for those cheap BT/USB ELM327 OBD-II adapters."

Looks like it will be worth watching the progress of it though.

Unless I have misunderstood, it looks like it might do fuel mapping and other ECU/TCM tweaks. The attractive thing is that it is genuine FOSS and hence unquestionably legal.

When I get time, I'll delve into it.

Let us know how you go. I'm too shit scared to try anything now. I re-imaged my Windows 7 laptop thinking that it did a successful write once, and it was just after re-imaging, so might work again.

Started heading down stairs and chickened out thinking about the hassle if I wipe the ECU and can't reload it.

The thing is, now is the time to do it. The misses is away for the weekend, so if I have to pull a few "all nighters" trying to get the car running again then I won't have her in my ear.
