Surely still not waiting since October?
Don't have my Fc anymore but from memory on the Commander go to Settings then INJ.
You should see all 6 injectors sitting at 100% if she was running stock.
Doing the maths 444 stock injectors V's 1000 new injectors gives a new duty cycle of 44%. (I presume this is in a Rb26)
I'd just slot in 50% into each injector spot.
Let the tuner set the new lag times. Datalogit can access all the lag time V's voltage tables, you only see the 12V value in the hand commander.
That will get it running and drivable to your tuner.
Lag times vary according to voltage.
Datalogit will allow inputs at 16v, 14v, 12v, 10v, 9v and 8v.
Your tuner will need the manufacturer's brand of your 1000cc injectors so he can look up the correct lag times.
When people quote a single lag time, it's usually the 12v or 14v input as that's the stable voltage when the car's running.
But for cranking etc, you need all lag times and that can't be done via the hand commander.
