Ok, I've been talking to tephra and Aaron at English Racing as well as a few others. It sounds like a few guys have this working, and a few guys have it working, but with issues. Here is what I have learned in the past day.
• "Mode23" is not needed/does not exist for the CT9A (Evo 8/9)
What you do need is the following:
• Tactrix 2.0 openport
• SD card inserted into said 2.0 openport
• Have SD card already formatted as FAT16 or FAT 32
• Install the logcfg.txt file into root directory of micro SD card. (attached to this post)
• If you want to lof AFR's, follow this
how-to
It sounds as if this is working flawlessly on at least one car that I know of. He has confirmed it is working on the 88580714 and 88840016 roms so far. I am not sure how or if it will work on the 88590015 rom that I currently have with Tephra v5.10 installed.
The thing that really makes this tougher is that the guys who are using this are all from either Europe or Australia so far it seems.
