Found on Ebay uner suzuki burgman 650

These have been asked about several times in the last few months. Try doing a search, here's one: viewtopic.php?p=339604#p339604

sounds like a nice Snake-oil idea/scam ... I am sure lots of people are going to think that you can gain about 25hp by adding a chip to your scoot, but don't wate your money or time and do some research on the basics of how to increase horse power by making mechanical modifications...

I am sure there is a rev limiter on the scoot and maybe you can bypass it somehow, but I doubt that it will result in additional ponnies at the rear wheel.

let us know if you decide to try it out...

These chips often do work in other vehicles, I have seen it with my own eyes on our own dyno. 25 HP sounds pretty extreme on a 54 HP vehicle, but I believe the ECU of the 650 also controls the ECVT, and by remapping that pig I could see a potential massive HP gain at lower speeds.

I posted a comment on Colchicine's link to the previous discussion, check it out before you judge

Just go for it and report back. For some reason some think the bike will disintegrate if one is installed. The HP claims are excessive, but 10 horse power might be possible; 4 to 6 more likely. could even help fuel mileage a little from not being so lean.

We need someone on here to buy one of these and do a back to back dyno run on a 100% stock Burgman. Someone NOT in any way affilitated with ANY Manufacture of like parts. In all my hotrodding years, I have read so many claims for different manufactures on HP boosts. There are so many out there that if you had a stock 2 barrel Chevy 350 and added all the "bolt ons" up without doing any internal hardware changes, you'd have over 150 more HP's. Like 10% for one add on and 15% claimed for another....

I, IMHO, will say that just bolting a "CHIP" on without adding more air and better exuast will gain only a few HP, like 2 to 3, on a Burgman. Now IF there was a hot cam, Cold air intake with highflow filter, Headder, bigger bore TBI's... then your engine would NEED a chip to re-adjust all the timming and fuel events and YES you'd gain about 15 to 25 HP, for about a 35 to 40 HP total. But with whats avalible out there for hotrod parts for a Burgman, a pipe/muffler and a highflow air filter, then IMHO, a chip set will not gain enough to go drag racing on SUNDAY, unless you already race on SUNDAY. I would guess that with a Leo Vance pipe, K&N type filter and a chip set you'd gain about 8 to 10 HP. Thats really is alot for a 800 lbs bike with rider but without the pipe and filter its not worth the time or cost.

Now adding a "chip" set to a big V8 or better yet a Turbo Deisel (TD) and YESSSSSSS, big power gains. The chip set does change many things on a TD but mostly it raises the boost higher, then adds fuel.

Its like all these Import cars that the driver cuts the OEM muffler off, puts a "FART CAN" pipe on and now thinks its a racecar. Or adding a HUGE wing to the rear of a FRONT WHEEL DRIVE car for more down force. It does add down force to the rear wheels and takes it away from the drive wheels. Take that same wing and add it in front (I cant see) and the gain in down force is useable.

These posts can go on and on, like a Darkside or oil thread. Peace, DaveJ

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.

The chip in the ad is a joke, A real one COULD be real slick
