I agree Dave, 25 HP sounds unreachable by ignition and fuel
mixture changes alone. If you read about this particular chip
, it is a joke, all it does is intercepts the intake air temperature signal and tells the bike the air is cold, which will richen fuel
mixture and advance timing, but not much or in a controlled fashion. The "bike" I guess (looks more like a car dyno sheet) shows a bike that already had 178 HP being improved, from those starting numbers 25 HP boost would not be so surprising.
I am totally against the chip
in the add cited above. In any case, you dont need this chip
to do this, just buy a resistor that equals fairly cold air coming into a Burgman, say (scratches head, breaks out service manual) 3K ohm from radio shack for 50 cents, disconnect the IAT sensor and plug the resistor into the harness connector.
Never the less, if someone out there makes a real tuned chip
, one that goes in the ecu,the gains to be had from remapping timing when the production of extra NOX is not a concern IS substantial in every vehicle not prone to knock, especially if you use higher octane fuel
. Enriching the fuel
mixture at full throttle also helps and allows you to advance the ignition even more. But more then anything, the 650 misses out on a whole lot of power and fuel
economy due to the way the ECVT is mapped, even in power mode. At any speed under 55, I think a 25% power gain could be achieved from remapping the ECVT alone. As to fuel
economy, at around town speeds I get 20% better fuel
economy by using manual mode, and you have to consider I can only change ratios in 6 steps, the ECU can do it in continuously variable steps so it should be able to do better yet if it's number 1 priority was not avoiding vibration.
in the ad is a joke, A real one COULD be real slick
Those who would trade essential liberties for a little temporary safety, deserve neither liberty or safety.
