I was playing with the software on my new Powercommander III for the CBR 1000 and was using the Map Comparison feature to see what the differences were between the zero map M125-000(same as ECU) , the stock map M125-001(optimized for stock exhaust and air filter) and the M125-006 Yoshimura RS-5 full system map . I was more than a bit surprised by what I found. Logically, I assumed the full system map M125-006 would be richer throughout most of the higher rpms and load settings compared to the M125-001 stock map due to expected higher efficiency and airflow volumes and thus the need for more fuel. I was shocked that the stocker required more fueling at almost every throttle opening position and rpm combination. I then got to comparing other maps for other full systems by different manufacturers and all except two, Micron and TI force, were flowing substantially more fuel at most throttle position and rpm combinations. The Yoshi, MIcron and TI Force curves were all very similiar. What does all this mean? I'd be lying to you if I said I knew, maybe it means nothing but thinking back to basic thermodynamics from college days, more fuel = more energy released = more power.
Either my logic on all this is basically flawed, this is more black magic than science or the Yoshi, Micron and TI are duds. Time will tell but I think I'm going to try the stock map M125-001 first without the Yoshi and see how it runs. The mapping is very different i.e. much richer than stock and I'm curious how it will run.
