ok bud, heres the instructions, hope it makes sense !
There are two settings in the first injector box, size adjust and lag difference.
For size adjust, you need to divide the standard size by the new size and multiply the result by 100 to get a percentage. So in your case, it would be (440/1000)*100 = 44% ( I think Datalogit defaults to 110% for standard 440's though for some odd reason ). Basically what you are telling the ecu is that the new injectors only need to be on for 44% of the time the standard injectors were on for, to flow the same amount of fuel.
For the lag, you will need to find out the lag time of your new injectors and also the lag time of the standard injectors ( I don't know what the standard ones are... ? ). The lag difference is the difference between the two. So say for example the standard ones have a lag of 0.7 mS and the new ones have a lag of 1.2 mS, then the lag difference is 1.2 - 0.7 = 0.5 mS. The standard setting is 0.0 mS ( ie its only the difference between the standard ones and the new ones you need to put here, not the actual value )
For Inj duty versus battery voltage, take a guess...
Should be good enough to get it running right before a remap anyway. Hope it makes sense !
