How exactly do you use the prom equipment talked about on E-bay to calibrate
OEM computers?

Hi,
Right now I have a single blade large round TB originally off a First
EFI system (equates to about 950 cfm by square area) but am thinking of
getting one of the large single oval TPI type TB's from TPIS(1350 cfm)....

Hmm. Speaking of correct injector sizing, how can I find the correct size
for
my Ninja 900? I was performing some calculations, and it appears the bike
has
airflow similar to that of an LT-1 or modified Mustang (72mm single-plate
TB,
52mm dual-plate TB). Does that suggest that I would need the same size
injectors? I know stock Mustang 5.0s have 19lb/hr injectors, and those
using
70mm TBs typically have 24lb/hr squirters. Dunno what Corvettes and Camaros
use.
Also, any idea on how to set up an initial fuel map? I'm working out a
system
to use closed loop below 1/2 throttle and 6000 RPMs, then go to a mapped
open
loop above either entry test. However, I don't wish to kill the 900
immediately when I fire it up... I was thinking I could find the correct
injector, then look up (somehow) the engineering specs for said injector,
and
perform some calculations to get the (hopefully) required PW for the given
airflow.
Thanks,
Bob Moon

I came across some fuel injectors but the owner doesn't know much else about
them other than a part # (17104487B). Can anyone decode who or what size
these injectors are?
thanks,
