Don't enable sync on both profiles, only PF2. It will sync to the next lowest profile, PF1.
Disable 'divide by 10' on both profiles - as is you're times are tenths of a second and you need more than that.
For PF1, try times of 10, 10, 0
For PF2, try times of 0, 10, 10
These are taken from Curt's testing on various tanks and are documented in the old Neptune V4 user manual. See if they help at all.
