Powerfc Setup - Injectors, Afm

[Kaido_RR]

hello

i just got my PFC, and after seraching the net for an english book, i could only find a very outdated one of the apexi usa website.

Here is my problem:

740cc injectors

Z32 AFM

now for the injectors does it work like these

stock injectors 370cc so 370/740 = 0.5% so that is the injector duty cycle.

What about the lag time, stock is 0.528msec what would it be for my 740cc nismo injectors?

(I have work out that if the 740cc have a bigger lag time, i need to take that away from 0.528, then whatever that value is use that correct? e.g 0.81 - 0.77 = 0.04 so therefore +0.04msec)

now with the AFM, in the book (the one that came with the PFC) it has 4 option for afm setup

1.r33 normal

2.power intake

3.80 VG30 Air-F

4.90 VH41 Air-F

5.Option

For the z32 afm its just option 3 correct?

I did i serach and couldnt find an answer for my question

Cheers Michael

You just answered you'r own question's.

lag time - I use +0.06ms

Make sure you have a wideband sensor before you go playing with the fuel map. The valve's on the map "for ovbious reason" are going to be very different from standard.

You'll proberly find that with the 740's and z32 it'll idle better rich.

i've just been reading some usa website and people are saying that the lag time for the 740cc injectors is around .6 to .8 :S

enjoy.

I'd use .2 or zero and just leave the injector correction at about 52-54% until you get it to the tuner.

rich is safe(er).
