I just finally scanned my dyno sheet from the AMR Superbikes tuning earlier this month. I also included a dyno chart of a stock VFR800 on the same model dynojet for comparison. I tried my best to paint them together, but that should be taken with a grain of salt, as my paint skills are poor. If any of you guys can do better, by all means go for it. on the first chart you can see two separate lines if you look closely. you can easily see a red and blue line, looking at the air/fuel ratios. this is a comparison of the map i downloaded from VFRD that had very similar mods to mine. as you can see it was pretty lean in a lot of spots, and actually a little rich in some spots. it pays to get your own custom tune done! me and angelo at amr were going through the notes supplied by dynojet for the vfr's. basically the goal was 13.6/1 for pre vtec and 13.2/1 post vtec for maximum power. also tuning must be done between 185 and 195 degrees. im pretty happy i did all my cooling mods before hand, as it would have taken for ever to have to wait for the bike to cool down after each run... my fan coming on at 197* and off at 182* seems to be the optimal settings for maximum performance. mid range is mch improved, mainly filling is dips. top end gain is Huge. by redline im up about 20 HP and 10 fl/lbs over stock. What you cant see from a dyno is how part throttle response and power as improved. i really find myself giving much less throttle and rpms to get the desired effect now vs before. the bike is super smooth now. its no longer twitchy applying the gas. no longer scary feeding in the gas while leaned over. no longer like a on/off switch while going through vtec under half throttle. also an important side benefit, the bike runs a good bit cooler under all comparable conditions!
