how me how corrections are made by the ecu!

im talking ABOUT MY BIKES FUEL MAP. what is there a problem with reading? MY BIKES FUEL MAP. you will NEVER pick up what i lay down
Listen, maybe people would take you seriously if you didn't constantly lay down such utter garbage. You live in such an insular and tiny part of the world, Everything revolves around your magical bike and the fanciful race cars you sniff around every so often. you have no idea of what goes on in the rest of the world. You have no idea how little you actually know. That is so very sad.

it squirts out the same amount of fuel regardless of which fuel type it is, at x rpm.
it's still running at x rpm with the same amt of fuel
horsepower, and the resulting forward motion is a factor of this engine at x rpm
so it should be the same?
but it's not, obviously...so why the less mpg?

i offer my ridiculous, unfounded and probably stupidly wrong theory.
while rpm & fuel volume may remain the same, hp could suffer, right? tharfore having to work the same engine harder to accelerate at the same rate, and to reach and maintain the same speeds. but yeah, i dont know a fucking thing.
mysalsa
but hey i don't know dick either.

i don't think so. hp is a factor of the rpm.. same rpm on the same engine should mean the same hp.but hey i don't know dick either.
actually i believe hp is a product of torque x revs. and like mark said (i think)... it's all about energy in the end. if one fuel burns less efficiently than the other, and your mixtures are identical, of course one is going to be less potent.
mysalsa
and it is all about energy.
if it's running at 14k rpm (either fuel being dispensed equally), it's turning the transmission at the same speed, no matter which fuel, which is turning the final drive (driveshaft on a car, chain on a bike) at the same speed, resulting in the same distance traveled.
but why is this engine running at the same speed with the same amount of different fuels? that's the only part i don't get.
how is dude's ecu not adjusting for it?
my brain hurts.

i get what hesback is saying as well, and i'm not sure how it all fits together.it squirts out the same amount of fuel regardless of which fuel type it is, at x rpm.

so it should be the same?

Did I miss where he posted the second chart, showing the other fuel in use? Without that there's no proof that he's not just rounding off, which with E10 would be easy to do. The very fact that he's admitted he gets a fuel consumption increase defeats his premise. In the same way, his chart is useless given the large gradients between throttle positions it measures at when you're looking for 2-3% changes in consumption or conversely HP for a set amount of fuel. Get a line graph of it on straight gas and E10, layer them, and you'll see it, I promise. Be more clear than Al Gore's movie.

that is the same map that im using for E10 MO2X and 91. the reason that it cant change is beacuse the commander intercepts what the stock ecu is sending and says that X rpm and X tps. theres no O2. so how can it correct how much fuel it needs? i think that some people understand what im talking about now,
It doesn't correct how much fuel it needs. If you had reading comprehension above that of a tree stump you'd notice that I pointed out that a dyno of the engine running would show that it's making less power on the less energetic fuel, while spraying the same amount of it.
