Hi Darryl,
Check out this post:

Although this post it is for the G-Booster 160, I believe the issues are similar to yours. After adjusting your ACC RAMP to 33 seconds this morning I forgot to check your THROTTLE TYPE, it should be set to SOFT.
Just like my Booster 160+ on my BVM King Cat:
THEY DO NOT LIKE VERY HUMID CONDITIONS.
Good luck,
