I already have a tune running a 240E base supposedly, but I would be interested in trying yours out if you think it's worth it. I know you're extremely busy, but PM me if I can be of assistance. Your tune always looks so damn appealing!
Yes, I've tuned cars on ISTA/P 2.48. It's still 240E, so it's the exact same software that was in ISTA/P 2.47.1.
231E came into play on ISTA/P 2.46.3 I believe. The mapping is pretty much identical from 231E to 240E - only difference to maps is the oil temperature RPM protection level was lowered in 240E.
The ISTA/P integration level is across all cars, so a different number doesn't necessarily mean that the software has changed in a specific control unit.
