Sorry Michael,
They are kind of lazy or just stupid at Daystate America - they could easily have saved your custom setups prior to the update - and restored your custom setups after the update.
But anyway all your speeds would have changed after they installed the the ultra firing valve.
I have redone all my custom factory mode programs two times now in my Delta Wolf .177 HP - and it takes time.....
First when i installed the ultra firing valve - I experienced major changes -especially in the lower fpe programs.
Then second time after i opened the transfer port and installed a 1.5 mm pinprope again major speed and power increase.
The speed increased so much that it came out of the +100 / -100 fps that it demands to for the rifle to self correct the speed.
To find the Pulse width and Volt that i need I created 10 custom Advanced programs named T1 to T10
All test programs gradually increasing from pulse 1700 / 58V up to pulse 2500 73V.
This is in principe the range I need from 8 fpe up to +35 fpe.
I use these T1 to T10 to to find the data i need to enter in my custom Factory mode programs.
I test like this:
When i test 8-10 gr pellets or slugs I test shoot program from T1 up to T4 or T5
When i test around 13 gr. pellets or slugs I test shoot programs from T3 up to T5 or T6
When i test shoot 16 gr. pellets or slugs I test shoot programs from T4 up to T7
When i test shoot 20 gr. pellets or slugs I test shoot from T6 up to T10
Every time i fire 4-5 shots and note the speed i get when shooting the actual program.
With the speeds that i got from tests hooting, it is easy to enter custom factory mode programs on my Laptop PC for each Pellet type or slug type i tested.
Afterwards I upload all my custom programs to the rifle and now I can as example select JSB Knockout 13.43 Gr in the rifle enter a speed like 880 fps and it finds any speed i enter after 4-5 shots.
If i keep shooting at that specific speed I entered, it will automatically save the Pulse width and the voltage needed to reach that speed as soon as the rifle has shot 4 consecutive shots within -4 fps to +4 fps of the requested speed.
So the next time i take the rifle out It already knows the settings needed to set the correct speed.
And with the (Please forgive me for saying this) poor regulator, that drops the regulator pressure 5-8 bar when shooting from 250 bar to 180 bar - the Factory mode do not care - it does a great job holding the same speed all the way down to close to the reg. pressure.
I love the Factory mode......
So a little pre-work and you will have the Worlds most easy rifle to tune and use.
Sorry I do not own a .25 cal so you will not get any help getting my custom Advanced and factory mode programs for my .177
But its same stuff. In the beginning I tested all speeds guessing pulses and voltage by trying and testing - With my T1 to T10 it is much easier.
