IMO a convention with DCS modules should be reheat/wep for all aircraft occurs at a set position. Ideally adjustable so different hardware can be catered for.
So far I've tested the Mig21, Mig19 and Harrier with my new virpil throttle and the detent I set for the Mig19 coincides with reheat on the 21, and 100% with the harrier....
Be interesting to see if its the same for the F14 later today
