Title: Siemens blue 840cc/870cc injector settings..
Post by: lost on October 01, 2011, 11:33:13 pm

Does anyone know best vems settings for this 840cc injector?
I'm using six of them for just 240HP

Siemens injector 980cc HighZ

Siemens 110324 injector high-impedance injector.
length: 59.35mm between O-rings (middle to middle).
New style, all plastic, fully compatible with old style (dark grey color, pencil style)

    Flow Rate: 840-850cc/min @ 3 bar (= 300 kPa = 43.5 psi). 80LBS/HR
    Flow Rate: 970-981 cc/min @ 4 bar (=400kPa = 58 psi)
    If you order 4 pieces or more: with normal AMP injector connector (unlike the picture, no adapter needed). Resistance: 12-16 Ohms (series power resistor not needed)

open time 0
rampup 816
rampup volatage comp 4080
voltage comp 896

disable pwm by using 100%
and peak time of 25.5

i have had great success with these injectors on pump gas and on e85 at very high base fuel pressures

however your injector is pretty large for what kind of power you are looking for.. you could have easily make that on 60lb siemens injectors

edit: there is a thread on these injectors before that had good info and some calculations on the injectors. fuel pressure will make changes as well
