Can you temporarily swap the ECU, unmarry the accessport, then swap your ECU back in? You wouldn't need to start the car to unmarry it.

Here’s the rattle noise. Sounds disgusting

I’m referring to LTFT + STFT. It’s a gen one. A valve was burnt before the rebuild so it’s possible this was a problem before.

Also - the injectors have never been serviced.

It's the base high flow down pipe tune from VersaTune. The MAF is calibrated for the correct intake :). Also, I know much more about software development and reverse engineering than I do about engines, unfortunately.

Hello everyone, I need advice on how to troubleshoot a problem with fuel trims. At idle, the fuel trim drops to nearly -20. Under light load, it increase to around +/-5%. As load increases, however, the fuel trims increase to 20+. Mods are autotech internals, catless downpipe, and JBR Tru-3.0...

Dev here. Life got in the way and I've had no time or motivation to continue working on it. I just finished building my engine and I'm still trying to diagnose some issues, but when I'm done with that I may pick up work on the software again. The hard part is already finished and it can...

The wheel speed sensor data is handled by the ABS module which is likely sending the CAN frame with vehicle speed to the instrument cluster and ECU. I'll check to see if that's the case after I get my car running.

Gear ratios: I also found a scalar related to the vehicle speed sensor (706.4 on speed6?) that needs further analysis.

The UI is in a better state now and there's 300+ tables and axes that need to be identified. If any tuners want to help identify them, lmk. I'm 90% certain the latest build finally fixed it. I was never able to reproduce it, but I did test the latest build on a fresh Windows install and it works.

I've been sitting on this for a few weeks but finally got around to ironing out the major bugs today. OBDLink SX support has been added and should work for any ELM327-compatible device. The new version can be downloaded here...

Unfortunately OBDLink and ELM-based cables aren't supported at the moment. It's up on the list of priorities as soon as I get one.

Everything helps! If you have a PassThru cable, unzip this archive https://github.com/LibreTuner/LibreTuner/releases/download/v0.0.5/LibreTuner-Release.zip and run LibreTuner.exe. Plug the cable in, switch ignition to ON, and run File > Download Rom. We've ran into problems with certain cables...

Thta'd be great! If you have the cable, before you try downloading you might want to go plug it in to your computer and open LibreTuner. I was having an issue with the cable not being detected, so let me know if the Datalinks combo box is empty on the setup screen. [edit] It should be fixed in...

I published v0.0.2 which includes a new definition for VersaTune. You will need to select "Mazdaspeed6 - VersaTune" on setup.
