To be blunt: What is called the "ETV Restriction” in the WRT software has no direct connection to the ETV control. I do not mean to offend you in any way but your understanding of the system and tables is at a similar level as Woolich support seems to have. Yes, you see an effect by changing parameters in this table for sure but there is no need to even touch the rev limiter because of these changes and there is no direct link to cylinder pressure. The only real impact to cylinder pressure comes from spark advance changes and this table has no impact on Spark advance at all. And touching the Spark advance maps at full load is really not needed as the Spark mapping is pretty much spot on from the factory. I think it’s for sure fun to tinker with a system like this and make some adjustments based on your personal preferences. As long as you don’t make any drastic changes you are likely to be fine and not trigger any torque monitoring.The main ETV restriction map would seem to be a torque/intake velocity mapping. So I only reduced the restriction from the torque peak up. And lowered the rev limiter 500 rpm to account for the increased cylinder pressure. The top rpm increase of the restriction (smaller percentages) can only be speed limiting. The ETV mappings in general would have taken a lot of effort on ducati's part. And have would take hundreds of highly instrument dyno runs. So all my changes are made incrementally iterative. The high gear race mappings in the high power engine mode would have been created for max output and throttle response. And that's exactly what you feel. I can readily feel and understand the hierarchy of the various etv maps so the names are not significant. The variables needed to be observed by the ecu to use optimum torque mapping would also seem pretty obvious. At 5000 feet and up it seems unlikely the torque limits would be invoked anyway. So I see the woolich software as really handy and have not invoked a single code.
BTW, there is no speed limiting. Some USA models have a power limit in the OEM map but Woolich is not displaying this table in the software so you cannot disable it.
