Failsafe Kicking in
I'm having an issue with my HFS-3 where around 5500 rpm the failsafe is kicking in and disabling high boost as it should. I can't seem to figure out what the issue is. I have purged all the lines, cleaned the jets and FAV. It starts flow at 4000 rpm and gets 4 or 5 bars then cuts out at 5500 rpm.
The car is 01 S4 with high impedance Bosch EV14 injectors.
When I first installed the kit on my base tune I did not have any issue, held 4-5 bars of flow to redline. Went for a tune and we were not able to tune for the Aquamist as the failsafe started kicking in. The tuner has tuned 300-400 aquamist cars with no issue like this before. Tuner said he thought it could possibly be a bad FAV?
