The HFS-6 allows you to have full control of ther failsafe trigger sensitivity.
it appeared that the trip sensitivity of failsafe is set too high. the trimmer marked "FLSF SENS".
- Fully counter-clockwise: 100mS (very sensitive - grace periofd is very short)
- Fully clockwis: 600mS (grace period is extended)
"grace period" is the system's response to a "over-shoot and under-swing" situation before the failsafe mechanism is triggered. This is relative to the WL and WH gap width.
For the time being, set the failsafe as follows:
1. "SFLSF SENS" to filly clockwise.
2. Set the SC to display 5-6 bars across at full boost and RPM.
3. Set the WL to fully counter-clockwise (almost no under-swing detection)
4. Set the WH to full clockwise (almost no over-swing detection)
Get your tuning done and then narrow the "Failsafe" window gap slowly. (#3 and #4). Perhaps 10 clicks. Once you have experienced no trip, wind the "FLSF SENS" in the counter-clock direction to decrese "grace period", ie more sensitive or quicker response to a "over-shoot and "under-shoot" situation.
