These were some simple test runs and uploads to make sure MHD and all components were working properly and not throwing any codes.

So that weird RPM idle thing came back with this file. I logged it luckily too, the error code being control module fault. After then turning the engine off and then back on, the car acted fine. The car seems to be running worse with this file however, many more misfires I can feel. From the files attached, the first is the cold start idle issue. The other three are the somewhat oscillation feeling during normal load driving, but much more pronounced, like misfires or even predet? I have reverted back to the previous file and didn’t do any WOT’s on this one.
