I take off and send in the ECU in and its flashed according to my bike (Full Brock's Duals and PCV (which will obviously come off... Or is the actual bike taken to be tuned?
In simple terms, we have 3 tuning steps:
1. Chassis ~ Olins/Penske/Yabayooyoo is one type tune to the bike.
2. Engine ~ Port/polish/cam/stroke/bore/blower is the next type of tune.
3. ECU (fuel/ign) ~ Map making is how you change brass or fuel jets, but this time it is a frequency tune, or fuel injector duty cycling. This is done via making basically numbers that represent a timed delay more or less: is this frequency coming out of a box. That delay is like saying a duty cycle, or the time the injector is opened at said cycle or timed frequency. This is how you jet a fuel injected bike, if it was an apple and an orange was a brass jet. Both do the same or mimic each other in a way to achieve the same result.
I assume the ecu flash is going to provide a more "direct and effective" a/f delivery and as a result, more efficient and powerful than what I get from the PCV?
SomeWATT, yes. If say we look at a checkerboard layout, those are the [climbing] numbers [in the squares] the ECU uses. For in each square, down is rpm [the faster we spin], and to the right is throttle position, or how much fuel [demand] we need to calc for this timed event. If we interject those two angles, we see our duty cycle needs this frequency for this rpm, this throttle opening. Think of it like that if you will.
If we add a pc, we are layering over another checkerboard with the same square patterns, but this time, we change those numbers in the blocks. If the pc can mimic the same maps you can lookup with a flash, you are using the pc as this flashing unit that can capture this one frequency, change it to another, mimic the flash = You just paid for a redundancy no matter how you look at it.
Flash: There is no turn off back to stock unless you reflash it back or have it mailed back.
PCV: You flash in the pc, not the ECU. You can turn off the flash of the pc, ignore mailing in some other tune you rather try. You never flash the ECU with a pc, but the pc itself.
Flash: There are presets to toggle off, as in limiters for mph and rpm toggles to gain rpm.
PCV: Also can move your limits as well.
Flash: If you rather run lean, you have to send in the ECU each time you want to make a change.
PCV: To run in stoic, or lambda like a car, meaning, best economy under light load, you can run with an 02 and have the pc learn to run at best power/best economy. This is where you'd have to preset the ECU down to a leaner condition to obtain close to what the pc could do by its built-in learning process.
