Crescent suzuki remap :)

Indeed.
An old saying with bike dyno sheets:
"It's not about the peaks, it's about the area under the graph"

if you are refering to the air / fuel graph thats spot on, right ratio for a street bike is 13.2 .. and look at my first run 6k rpm result, bike was running super lean.. and as that is cruising rpm the bike would have run hot.

AFAIK, you can improve power by running leaner than 13.2 but you sacrifice engine reliabilty and thats what race bikes do.. I'm glad I got it done 1 day after the decat or I could have done long term harm to engine.

after the remap look at the fueling graph, it's almost dead straight, result! ..the knock on of well setup fueling is a optimized power / torque curve, but then it would as it's all the tuner adjusts anyway

. Remaining dips in power delivery are just untunable due to mechanical factors in engine / exhaust etc etc

what I can't understand is guys on forums with power commanders setting up maps themselves without a dyno, sure you can try the butt dyno but you may well knacker your engine

edit: I might be reading this graph wrong as I aint a tuner just a forum warrior

Very true- with mine, it's up to just shy of 80 at the wheel from 67 stock (SV650) but the extra power's basically irrelevant, what makes a huge difference on the road is the delivery, and the curve. With mine, the bike originally choked after peak and the power fell like a stone, which meant shifting up short, now it gets close to peak 1000rpm earlier and stays there til the limiter, which means I can stay in the same gear for longer (I did a lap of knockhill in 3rd and in 5th the other day, just because I can ). I couldn't care less about that extra 20% power really, you just adapt to it.

Thats a good increase, but by improving throttle response via remap you are generally also gonna increase power / torque. The crisp feel of perfect fueling and optimal safe power are linked hence your 20% increase.

All the benefits of correct fueling mean the bike is better to ride in every way.

Yup. Though that's also down to cams, filter and exhaust. It's impressive how much difference a remap can make to even a standard modern bike though, I rode one of the naked Fazers just recently, and frankly it was broken, it just didn't work right... But enter one power commander and an hour in the hands of the local race builders and when it came back, it fueled as well as... Well, almost as well as a carbed Hornet
