I have a euro MY98, OE injectors are phase 1 380cc (densos IIRC)
I have fitted an Apexi PFC.
And have now fitted Nismo 550cc phase 2 injectors, bought from Zen.
Have been putting off mailing Paul to find out the difference in lag times for the injcetors, and also what the PFC consider as "0", now that the Zen email is down I post it here insteda, besides, I've been searching the net for this info and never found anything so anybody with info post all injector lag times here!

 

Telephone works

 

Your injector setting will depend on the current setting, but I would go for about 74% of your current setting. The injector lag for those injectors is 0.71ms but that's at 3 bar fuel pressure and 12v, raised fuel pressure will slightly increase lag times.

But you can't be sure the old injectors have a paticular lag time, as you Apexi got it correct in the first place! I would try +0.1ms on lag time to begin with, and see how you get on.

Thanks Paul!
The Apexi can only alter lag time with 0.02mss increments so 0.02 it is.
But I realise that I just have to take the car to somewhere where I can get a wideband and check up the map properly

 

you can go +0.1 not +0.01 (see decimal place!)

cheers

Ah!
