Injector Dynamic 1000cc injector global/deadtimes?

[19BLACKGST98]

I just got ECMlink V3 and I'm trying to do the initial set up. I have the software installed on my laptop and the cable drivers installed so the next thing I need to do is adjust the global and deadtimes of my ID1000's.
My injectors are not on the common injector list on the ecmlink forums and ive done searches on both forums and havnt had success finding them on google either. I found this but I'm new to tuning all together and this doesn't make any sense to me:

I figured someone on this site runs these injectors and knows the global and deadtimes for them.

If it was me, I'd take the data for 43.5 psi (our stock fuel pressure) and plug them into the InjBatteryAdj table in v3. I know the table shows 7 and 9 volts instead of 8 and 10, but you should be able to read the link below and get it input and adjusted properly.

Then for global, just use the calculator that's built in to the Fuel tab.

Ok thanks. I just talked to my mechanic and he said the deadtime should be right around 300. He said you subtract the ecu's stock deadtime setting 490 I think is what he said from the 805 (from the 43.5 16v reading above). He said to just start from 300. He told me to just hold off on doing all the link stuff until my other problem is figured out.

Thanks for the reply.

EDIT: The wiki link above is way over my head unfortunately

EDIT: after doing a little more reading I think I understand..I would still have to subtract the stock injector deadtime from all of those listed though correct? Thank you.

The InjBatAdj table is the starting point for deadtime calculation in the DSM ECU. The numbers there are in micro-seconds and do not need to be subtracted from anything or adjusted in any way. They are the base numbers ECMLink starts with in calculating a final deadtime. If you adjust these numbers, you do not need to subtract anything. Treat them as "total" deadtime *unless* you have adjustment entered into the Fuel tab.

The deadtime adjustments in the Fuel tab are added on top of the base InjBatAdj table values. So if you have a total deadtime that you want (1000 usecs for example) and you have 690 in the InjBatAdj table at 14v, then you could either:

1) Enter 310 into the Fuel tab for some quick, easy testing (1000 - 690 = 310)

or

2) Just enter 1000 into the InjBatAdj table and make sure the fuel tab adjustments are zeroed out.

Either way, you end up with 1000 microseconds.

Thanks for the reply. That makes sense.
