No.

The AEM EMS is configured for high impedance injectors. Your injectors are low impedance. This is a mismatch, like plugging a 4 ohm load into an amp channel that is engineered for 8 ohms. Maybe you can better understand it that way.

 

Hmmm I guess that is it. I am just saying I have seen guys run larger turbo's on smaller injectors with using the stock ECU Vs. the AEM EMS.

It's one of those things that you know, but finding a resource that confirms it takes a bit of work. A quick Google turned this up from Accurate Injector Service:

"Most flow ratings, while measured at anywhere from an 80 to 100-percent duty cycle, often use the lower of the two numbers."

(From: http://www.accurateis.com/whatinjectorsdo.html )


I believe the manufacturers rate injectors conservatively because they intend for you to size the injector such that 100% planned capacity is actually 80% duty.

 

ok good enough.

It seems people are having a tough time understand most of this stuff Thats why I made that calculator... so people can enter in thier own info and see what it comes up with. The problem is people dont really understand how the fuel system works anyways.

 

pm me how much you want for them...

i currently have 750's but i plan to run a little upwards of 30psi in the future.


so i need to upgrade

 

Think of the injectors as leaks in the fuel rail. The higher the boost, the bigger the leaks, and a *much* greater the volume the pump must flow to keep *increasing* the pressure in the rail at the same rate as the boost rises.

The point of increasing pressure in the rail is because the pressure difference in the rail must *always* be around 43psi greater than the manifold pressure to keep the injectors flowing to spec. The rail side of the injector is always kept around 43 psi greater than the discharge side. So when the boost goes up, the rail pressure has to keep pace psi for psi.

 

what we learned from this thread:

again, we learn TED B. is the shizzle

 

Well then I get half the output b/c I just halved my impediance Just kidding about that though, thanks for the info. Still waiting to try your cam gear settings

 

Bump on my question, plus your PM box is full.
