That make sense to me to a point, are we following the same track of thought, like for example putting a 850 double pumper Holley on a stock 289? Dumping fuel, black smoke, bogging down.
The Holley 850 carb is totally dependent on how much fuel is dumpped by acc pump, jets and power valve ( along with throttle bore postion) The motor is not supporting the specs ( high compression, headers, high lift cam ect...) to use the air/fuel ratio that a 850 cfm offers, so a rich condition will exist on a stock motor, dump fuel and blow black smoke...
.. If the motor was built to support the amount of fuel and air offered by the 850cfm it would run as intended.
OR in contrast, being EFI computer driven.
Not really up on FI stuff, so help me out....
Ok so if a efi car is computer controled, say by a stock untouched computer ( calibrated for 19 's) running stock 19 injectors, running a calibrated stock 19 MAF, the computer will tell those injectors to let a certian amount of fuel in, at a certian time in at what ever lb is needed at that point in time. If the computer requests 19lbs, the 19lb injectors have the capability of delivering that fuel.... Am I thinking right>?
So if the same stock engine as noted above has a set of 24's installed, (same 19 computer, same 19 maf) will the 24's act like the 19's and deliver the proper amount of fuel requested buy the computer?
Or is the 24 injector calibrated different.... Say at 30mph a 19 will flow a calibrated amount of fuel, does the 24 injector designed to flow more fuel at that same speed, or does the 24 only flow what is needed by the computer.
Realizing that the 24's have the capability to flow 24 lbs, but when the stock 19lb computer and stock 19lb maf send that same 19lb info to the 24's do the 24's flow the same amount of fuel as the 19's?
Follow me? The 24's can flow 24, but if a computer is telling a 24 to only flow 19, will the 24 respond, and flow 19 supporting only the 19lbs required? (understanding that a 24 can flow more)
Now if the same motor above is connected to a computer, and MAF programed to 24lb, and the motor has 24 The injectors should take the info from the computer and flow 24 if asked to by the computer. In turn flowing more fuel into the motor. AM I on the right track?
Is that how the process works??
See at this point I am still learning about injectors and efi options.
If my question is confusing, now you know where I am at !
Basically If I put 24s on a stock 19 motor, it should only flow 19 as requested by the computer.... it should act like a 19 .....
Or again, am I off on different planet?
Again.... Just trying to work it out...Hate to be such a dumb ass..
Let me know what you think or know..
