Yeah no, don't quote me on the exact number but I think it's like 1 degree between 20 and 30, then 2-3 between 30 and.....the next breakpoint which I can't remember off the top of my head.
Not saying you're wrong - there might be differences between regions in how our ECUs are set up. However this is how mine is calibrated. I just assumed every M156 was the same with regard to what I said to Skratch yesterday.
Skratch - 90F outside temp? Your engine bay must have been roasting in the ~45C range then surely.... I'm gonna say 5 degrees were pulled (also, an OE Tune on a good day likes to be at around 27 up top). But we'll never know for sure because....you didn't log your IATs Next time please...
