Okay, tested the new ROM and definitions;

The good
  • The high octane and low octane target loads were indeed swapped around, now able to set WGDC all the way up to 100%
  • EvoScan now reckons (yes I programmed all the cars details into it) the car is making 276 AWHP - I take this with a pinch of salt, the rolling road in 4 weeks will confirm accuracy

The bad
  • The Bit Mask input has either changed significantly since the alpha or the code is just totally broken
  • Speed limit appears to be broken too, despite using speed to switch maps, this requires further investigation

The ugly
  • Looking like a prick as I tried to test the new ROM by racing a Seat Leon Cupra R off the lights and hitting the 4000 RPM rev limiter I put in for Valet map because the wrong map was selected

I'm gonna do another test tonight, when I copied stuff from the alpha ROM across I didn't set the scaling, I just copy / pasted values expecting it to paste the raw hex value over the top. I'll update this thread tonight when I get home
