Anyone knows the lag times of 850cc Denso? It would be also good to know the BATV vs INJ lag times if possible.

I also need the lag times for 740cc Nismo injectors. Anyone knows how find the informations like that?

cheers

 

Some generic data:

cc flow lag
---------------------
550cc: 0.73msec
660cc: 0.75msec
850cc: 0.77msec
950cc: 0.80msec

It isn't critical as it only slightly affects AFR.

See attachment for stock bat vs lag.

 

Thanks. It has a big effect on my afrs. Not a rx7 though!

 

SARD/Denso 850cc

Lagtime = .85ms

16v = 0.568
14v = 0.768
12v = 1.048
10v = 1.408
8v = 2.008
6v = 2.840


It really affects idle more than anything else.
