Message: [QUOTE="Chatham036, post: 1399492, member: 13047"] The only thing we can do to slow the rate of the nozzle down is to reduce the ICP which only exacerbates the issue of atomization. The main way to make the truck feel "stockish" is through the ICP tables in relation to the base pulsewidth tables. It all comes down to how you profile the curve for the way the truck will run. Too much ICP too early in the RPM band can cause the throttle pedal to become overly sensitive causing a romp. Too little and it will haze while being sluggish. There is a balance somewhere in the middle that allows for the larger injector nozzle to run decently well although it will be more inefficient than a stock nozzle because of the reasons posted above. Since the stock nozzle has a slower injection rate, it allows us as tuners to have greater control over the pulsewidth window as well as ICP curves. Here is a loose analogy that might help you understand this concept better. Someone with a bow & arrow shoots the arrow past you. Your job is to grab the arrow as it passes. The person shooting has two different speed bows. One is 100 fps (stock rate) and the other is 300 fps ( 200% over stock) Will it be easier for you to catch the stock rate arrow? or the 300 fps arrow? The catching of the arrow is to simulate the target fuel quantity. Say you need to hit 80 mg of fuel per stroke to run efficiently. If the injector has a slower injection rate, it will be more accurate in achieving the 80 mg than the larger nozzle. Another way to look at it, it is similar to trying to use the fuel pump and stop the pump exactly at 25 gallons. If the pump is moving a lot of fuel, it will be harder to achieve the 25 gallons than if you were pumping at a slower rate. [/QUOTE]
