But Jim never expressed an opinion!!! He just told you "I know the figures are high but the difference between them is what I'm interested in". Everyone can see the raw numbers are too high. Please read before you attack! He is the most honest person I have EVER met and is just sharing his experience for God's sake. And as for having '5 torque graphs some peaking below 2000rpm' his instructions to the dyno operator were to remove a flatspot at cruise AND to gain more power. The dyno they used was capable of determining throttle opening percentage and was therefore able to make repeatable runs at certain percentages of throttle opening, critical to simulating on road performance. Happy? No, probably not.
I emailed the shop with this dyno demanding to know why their figures were 40% higher than everyone else and they came up with rubbish that I'm in the middle of responding to right now, it's crazy talk they probably have farenheit and celcius mixed up in their correction factors or something but the dyno results are consistent and repeatable so the comparison is valid!
BusaGeek, you've lost me, someone said he had his busa remapped, he did NOT specify which of the many FI Adjusters was used to do it, cheese pipes up with 'yoshi box' and 'stone age', then accuses Jim of being offtopic for posting his experiences with doing exactly the same thing as the first poster who started this thread, and now you tell me I'M off topic because something cheese said was "a perfect description of a yoshi box"? WHAT was a perfect description? Likewise WHAT does not describe a Teka? Jim did the same thing as the original poster and his authorized Suzuki dealer happened to use a TEKA FI Adjuster. Who cares what he used? He gained 3.65% more power and has graphs to prove it but some people would rather believe that buying a box is the ONLY way to improve power. The original post was an attempt to help save people money I suspect, nice of him but he got flamed.
I only said that I didn't see how the other boxes could be so much better that (a) cheese would ridicule remapping the stock ECU, and (b) everyone would refute the additional power claims from remapping the stock ecu, simply because a map is a map is a map. I would hope that any programmer for a stock Suzuki ecu would give you access to every map entry and that if one is missing it is because Suzuki perform interpolation at that point. I dunno but would a piggy-back box be any different? Perhaps, I don't know and I freely admit it which is why I asked to be proven wrong, I like learning new stuff, but the point is you should not assume that there is no power to be gained by remapping the stock ecu, to the point of rubbishing actual dyno comparisons on the same dyno/bike/day just because the figures are high. For my money I'm a PCIIIR because I can create/upload/download maps when I make changes.
My point about the octane was in regards to the air fuel ratio demands. Our 98 has a RON of 98 (duh) and a MON of only 87 giving an Anti Knock Index (AKI) or PON of about 92.5 which is poor so I was wrong to keep waving the number 98 around like it was great, however we use huge amounts of toluene to achieve this octane (sooty!), which gives different characteristics to our fuel including a taste for rubber fuel components! It's so different that in mass stoichometric terms, BP Ultimate 98 requires a ratio of 12.0:1. By comparison BP 100 racing fuel (that's 100 MON, and 110 RON) requires a ratio of 12.9:1 and BP Regular Unleaded 12.5:1. These are BP's own figures and illustrate my point that if you tune a bike to a specific fuel that is quite different to the target fuel, you can obviously find more power quite easily depending on how different the fuel is.
Furthermore, does this not illustrate my point that cheese's constant request for A/F curves is futile? What use are they when as you can now hopefully see, different fuelds have different ratios for best performance? This 98 we have, imported from Perth in Western Australia, caused a hell of an outcry when it was first introduced, people were queuing up complaining about plugs turning black (and rubber melting). The solution was to change the air fuel ration and timing, rather like, oh I dunno, remapping your Busa?
This forum is vicious, not about helping each other at all.
