Hi all, just looking for some confirmation with this and please correct me if I'm completely wrong here (its a bit long winded but trying to get my head around this).
The standard computer has F and L Tables with an FL Switch based on throttle position and RPM. These determine the air mass that gets sucked into the motor, the AFR then determines the correct amount of fuel to go in and controls the injector pulse.
The PCV (with AT) map appears to only seems to have target Air/Fuel ratios (AFR), a % fuel adjustment and % autotune trim.
Does this mean the ECU still controls the ignition advance/retard?
And to my mind the PCV interrupts the fuel injectors and controls the injectors pulses and that's about all? Does this mean the map in the ECU still determines the air mass and pays a large part in general performance and is only "trimmed" by the PCV?
If this is not the case and the PCV takes care of all the fueling requirements does it only have the equivalent of the F table in the ECU?
Think I had a poor dyno tune a while ago as I was warned if I left the AT turned on my bike would probably lose some power. The map looked pretty similar to what I went into the dyno shop with. I reloaded Hanso's zero map and turned the AT back on and the performance got much better. I'm tempted to go back to the dyno shop, pay for a straight HP run then show them the result and ask them to explain, my ass dyno says its much better all round.
Any technical advice, web link appreciated.
Thanks in advance
