Hello,

Does anyone happen to know the specs for a set of precision 880cc injectors.
Like what psi they are rate at and the lb/ft value as well, in any units please. I need these to finish hooking up my AEM EMS

TIA

Mike

 

They are 83.80l b/ft

880/10.5= 83.80

I'm running those injectors aswell, with an AEM EMS...

Here's the battery offset...

thanks for the help guys,

for those using the AEM EMS
i am to type 880cc/min and 83.8lb/ft ( how did you get this number? and where does the 10.5 value come from)
correct?
I am going to use the turbo 440 base map what are the specs for these injectors?
any info is appreciated

TIA

mike

 

Not sure exactly why thats the actual number that is used but it is.

the formula is

880/10.5=83.80

83.80x80 for the duty cycle=6704

6704/.50=134.08

134.08 is whay eacxh injector can hold.

Multiply tha number by four for how many injectors you have

134.08x4=536.32

 

lb/ft? What the heck?

I presume you really want to know punds per minute of fuel flow. In which case, the standard conversion factor is 10.5. However, since cc/min is a unit of volume flow and lb/min is a unit of weight flow, the conversion depends on the density of the fuel.

They are rated at 43.5 psi, that is the industry standard. Sometimes they say 43, same difference.

 

Thanks for the insight, lol I know how to calculate just not always sure why certain numbers are what they are.
