R6 YEC ECU Baseline Map Question

[Mechanikrazy]

Long story short, I replaced an supposedly decked head supersport motor, which dropped a valve, with a completely stock R6 motor. The two maps on the YEC ECU are supposedly for U4.4 and U4.4/pump mix for the previous motor.

The YEC ECU software comes with "base" maps. Is this a usable map for a stock motor with a full exhaust? Or is that base map not intended for running, but only intended as a baseline for further dyno tuning?

I'd look at the maps for the U4.4 and U4.4/pump mix compared to a stock/base map and see.

On kawi kit ecu it is just a blank map and you still have to tune it.

My bet is all they did was add fueling for the U4.4 tune and you're probably safe to run it on a stock motor with U4.4.

My U4.4 tune is safe with pump fuel, it just runs a little richer under pump gas compared to straight U4.4.

No answers can really be given without looking at those maps to see what is going on with the tune. And i'd expect yamaha has some guidance as to what to do with regarding the "base" maps.
