Hi all, new to the site, good to meet you all. I'm going to throw one more nugget of info into the mix. I recently built a 420R here in the US and developed a CAN bus configuration file for my AiM Motorsports gear (Solo2DL/Smartycam/etc). I'm guessing it would work (or at least be close) for the other Duratec model variations. AiM also added a CAN config to their standard list in Race Studio 3 for a Caterham 420R, but it's a little different and cannot be customized. I couldn't see a way to upload a non picture file, so if anyone wants the AiM Race Studio 3 .xc1 file, DM me! Here's a screen grab of the gear in action.... It's a bit ropey visually but proof of concept is good. For my car at least no throttle input gives 23.5% (60 decimal), max throttle is 93.7% (239 decimal), so I customized the scaling to convert this odd range of 60-239 decimal to 0-100%. I can't make sense of why it's like that, but it works. Cheers Simon
