Help wanted on injector specs
« on: September 14, 2010, 09:52:40 am »
Hi!
Can someone help me with injector settings?
1) Part Number 01D030B (Lucas old 5208009, Lucas New 621031, Delphi old D3181AA)
2) Siemens FI114961 - Mototron INJ-GAS-006 - Accel 74620L - MSD/Edge 2030 ( http://shop.vems.hu/catalog/siemens-injector-727cc4bar-p-79.html )

Thanks.

I'm also searching proper settings for these injectors.
However here is a good info: http://www.racetronix.com/product/Injectors/FI114961_Brochure.pdf

Maybe wrong but current setup is the following:
Inj eff rampup 1200  (it seems too short according to the above datasheet + I got 100% duty cylce where it shouldn't been)
Inj open time 0
Inj Volt rampup 4080 (using TS diode)
Inj Voltage compensation 400 (no clue, but I think it should be lower)

I would use something like 670us for inj open time @13.2 (hard to say at what voltage datasheet value is)
0us for effective rumpup
0us for rampup voltage compensation
And somewhat 500...600 for injector voltage compensation.

It comes from my findings described here in post #5
