ritchening up bike. reasons?
i know the basics on it is a air pump with the ecu giveing it x amount of fuel weather or not it has enough air.
the beginning of the year my bike did not win the dyno shootout and i was down 6 hp and looking at my logg from the pull when i got home i found it was at 13 to 1 and ended up at 12.7 to the limiter. it was not there the time before.
now after replaceing the o2 sensor on the wego3 i am at 12.6 at 6000 to 12.2 at 11,800 then at 12000 it is 12.4.
i am going to check the filters and wanted to ask if me going from high test and setting it up on the 10% ethonal and not running only on low grade non ethonal if anyone thinks that is why it moved so much. i know it has to lean out some with the 10% compaired to strait gas no blends. did anyone test this or notice this?
till i took the logger off to put on the pulling truck (which i think the o2 sensor got messed up with race gas though i think it should not kill it dead just make it die sooner) and up to that point it was exactly where i had it at maxton. then it flaked out readings wise and the new O2 shows i am pig rich.
i forgot to add i just installed a new MAP sensor to try to trouble shoot some issues and i do know that could be the reason of indeed there was something up with the old one i had on used from ebay and tuned the bike from that.

i also know if the voltage gets low while running it will ritchen up the bike. i guess i have some things to look at till the weekend.
maybe the charging system is down though it has bright lights and the logger will say bow battery if it goes too low so that is only a remote idea.

i am looking for 12.9 to 13.0 on map A for the track and 13.4 to 13.5 for the dyno shootout.
the engine is as stock as it came new. i have no idea the CR really is.

The SAE and FAA charts that I've seen show that max power is produced around 12.6:1 AFR. Why would you want to go both slower and hotter? There's an unhappy place between stoich and max power where both CHT and EGT are maxed out, and yet power is off too. Aircraft tend to use something in the low-11's for AFR during climbout in order to maximize power, reduce EGT/CHT and minimize detonation.

no offence but i have actually tuned my bike at a dyno and know where it works good at for " dyno numbers" and i have been close on the track with my mph steadying out with afr in the high 12s. seems to be where my bike likes it. charts vs doing it seem to only apply to some i guess.

for a dyno shoot out you don't care about anything but a number I have seen some bikes want 13.8:1 for a number (of course it will be a slug on the street)

Not to get stinky or anything, but those charts are derived from doing it. I guess the whole dyno shootout thing is foreign to me, as a dyno is just a simulator, not a competition in and of itself in the stuff that I do.

the thing about the dyno shootout it is a bogus worthless test.
most of the operator are clueless have don't strap or even line the drum up.
I could go on but why?
a true tuner knows better at where to set a/F but for a dyno shootout it is a crap shoot.

i was around 13.5 where i got the increase with out blowing a lot of time tuneing. next time i go i am going to use my dragstrip map and play with timing to see if i will see anything and then compare to the track.
i know most of you guys do not care but i my self think it is fun going with my little 1200 and having enough stuff to win 3 years in a row. i lost this past may but like my other post it was ritcher than my track tune for some reason.
i lost to a well running setup 07 zx14 but the last year i had charts higher than him while tuneing. it would be fun to get close to him or get higher. then i just switch to the other map.
i am going to take the laptop to the track to set it up there after i get it close here running it over the bridge. the afr curve from the dyno and then 3rd gear blast make the same afr line dam near. i will be ok.
so after all the typical argueing on where one should be afr wise how about the origional problem you guys?
ever log 10% gas to strait gas and see a afr difference?
i know i was tuneing on the old map sensor i replaced cause i thought something was wrong.
what do you guys think?
