Pimpxs ECU versions and improvements

[rothville4]

My ECU is Pimpxs v1.2 I am curious what the timeline was on this ECU.
If the first release started with pimpxs what was added to v1.0 and so on?
It may be worthwhile to make a sticky with this info for each type of pimp.
It might save a tone of questions about what ecu has what features.

Version numbers don't effect feature set. Features have been the same from the start. Features only change with ECU model (PiMP, PiMPx, PiMPxs, PiMPxshift). Most version changes are just different firmware updates (which are available to all users to update for free). Some version changes are small board revisions/changes but again, these don't effect the end user in terms of adding any features. For example, our latest board revision will be to use an ENIG surface finish and it is only to make production more efficient and increase solder joint effectiveness while increasing our cost for each board by about $5.
