gti mad man · Post by **gti mad man** » Sat May 19, 2007 7:15 am

jim noticed my "injectors per engine cycle was at 2 he suggested i change it to 4 now to explain im running four fuel injectors of one bank connected all at once in parallel so do i still need to change this to '4'?

Also having trouble seting the 'required fuel' as im not used to american imperial units and geting confused could someone please verifythis please

vw engine, msne ,4 itbs hall sender from dizzy, no cat ,narrowband

engine size is a 2ltr
injector 215cc/min static flow

i know

air fuel is 14:7
number of injectors is 4

just the other two fields

injector flow???

engine displacement??

Engine size = 2000 cc
Injector Flow = 215 cc/min

Just select the metric units in the calculator

Not sure about all the injector being on one bank, but i suspect as long as you don't select 'alternating' it will be ok.

all you need to do is google a fuel injector calculator... and youll fine one that can convert CC's into LBS/hr...

215cc's from what i found is about 20.5 lbs/hrs. *YOU WANT TO DOUBLE CHECK*

and you can do the same with engine displacement.. MY 1.9L Saturn engine is 115.9 Cubic Inches displacement (CID). 2L is 122 cid

Google is your bestest friend

dont know about the alternating with all on one bank...

Wouldnt that mean that they would only be opening Half the time NEEDED.. because they are all on ONE bank... One bank fires ... then ANother bank fires... then one Bank fires then another... thats alternating...

that will really cause fuel tuning problems... seperate 2 injectors if your going to go alternating...

I seperated my injectors as such

BANK 1 goes to cylinders #1 , #3

BANK 2 goes to cylinders #2 , #4

for some reason with 1,2 coupled together , and 3,4 coupled together I got backfires during Acceleration Enrichment(sudden throttle movement) with that setup i havent

But i also only run 2 Squirts Alternating.. not 4... and my injectors are 525 CC's so dividing up the ALREADY small squirts could cause tuning problems
