Be careful with the voltages was told not to go above 6.9v don't know if that's a restriction on the ecu or the igniter.
If you're talking about the diesel igniter version, mine was sent with a setting of 7,2 from the factory. During winter it woudln't ignite under 7.3v. Turns out 7.3 was too much, considering how long it lasted, yet it was the minimum to get ignition (after over 15 seconds)
