Hey folks, lately I've been contemplating putting some more time into tuning the FZ to take advantage of higher octane fuel. From what I gather, in stock trim these bikes are supposed to run on 87 octane fuel, however given that the FZ motor is of the R6/R6S family (which make or power and are intended for use with premium fuel), there is surely some more power to be unlocked with this engine.
Earlier this year I installed a slip-on exhaust, power commander V, and had the the bike dyno tuned by a local shop with premium fuel in the tank (I've included a screenshot below). The dyno tune appears to be an across the board map regardless of gear selection, which is somewhat concerning since supposedly fuel and spark advance vary by gear in the ECU from what I've read in a few threads on here, and strangely only says cylinders 1 and 2.
Power and torque figures where right where they should be for a stock bike, 89 rwhp and 43 ft/lbs of torque. So in order to get more power out of the higher octane fuel, I'm under the impression I also will need to advance the ignition timing as well and not just have the fueling adjusted, since the burn rate/volatility of higher octane fuel is different. I am completely inexperienced when it comes to tuning for both fuel and ignition stuff, and I would like to gather some insight from anyone who has done self tunes for fuel tables, and also adjusted their own ignition timing. I would prefer to be able to electronically adjust the ignition (so I can have the option to adjust it independent of each gear instead of modifying the timing trigger wheel to "spoof" the ecu into adding a certain amount of timing across the board in addition to what is programmed for each gear), but it doesn't seem like there is an ignition module available for the PCV for the FZ6. From what I've been reading, the only solution may be at the ECU level itself with a "flash", however it seems like most of the open source or owner developed software resources for ECU flashing are limited to the R6 and R1.
Any advice from folks who modified their bikes in the manner I described would be much appreciated.
