Yeah sorry guys but V7.5 won't be getting the switching info put in it. We also planned on doing tune switching for the Cummins ECM from V8 scan as well. The switching systems aren't basic CAN messages, there is a bit involved and because of this the messaging format requires too much coding in V7 to do it.
Although this will be no good in a dyno situation we hope this new switching method we've been working on for the E98 will be a nice addition.
