During the off-season I've been installing more electronics than the U.S.S. Enterprise into my bike. One thing is a Power Commander and the add on ignition module and some other stuff. My question is... not knowing what the cost is, is it worthwhile to have the bike dyno'ed for a custom map or should I pick one from Dynojet that seems pretty close to my setup?

My bike at the time of being on the dyno would have a BMC race air filter and some sort of slipon exhaust. Ideally I would like to have two maps, one for the street with my stock exhaust which would be tuned for quietness and fuel efficiency and another tuned for max power on the track.

custom map worked for me. its was the only thing i could do after some of the mods i did. i was running really lean. had to tow the bike to get it mapped. this all happened after a few intake mods i did.

When I'm about to get anything for my bike I ask one question, "how many track days will this cost me". If I can live with the answer then I'll buy it. My bike is stock except for a damper and ss lines up front wich were both presents.

Also, if you have a newer bike (starting in 2006 for some sportbikes) be aware that some have closed-loop oxygen sensor feedback control loops, which sort of negate any mapping a standard PC may do, although there is a version of the Power Commander that will work with an oxygen sensor loop.

yeah, those are california or euro bikes. most 48 state bikes dont have 02 sensors. and power commander DOES make an 02 eliminator.

^ Correcto. JBaz earlier said on another thread a mapped PC would also decrease fuel economy about 20%... making a tank of gas last me about 100 miles in the city. Wtf.

Oh yeah, I looked at the new 1000RR today at the international motorcycle show in Cleveland. I nearly spooged my pants just sitting on it! Now that wouldn't need any power mods...

lol, the new 08 1000rr is fugly!!!! the only thing i like on the bike is the subframe and tail section. thats about it.

and i get about 115 miles before my fuel light comes on, and have about 20 miles max before i run dry. ive got a 4.8gal tank. F fuel enonomy, i want performance.

I rode an '07 1000RR. Before that, the only liter bike I'd been on was an SV. Big difference, of course, and the RR seemed almost as flickable as my 600. Got the wheels turning in my head :eyebrows:

Back on topic, I've heard mixed reviews about getting a custom tuned map. The mechanic at the dealership where I got my bike told me NOT to get it dyno-tuned at their shop, because the guy that did the actual tuning didn't do it for practical rideability, but rather maximum fuel/air ratio at all RPM (or something to that effect...basically, he said there were a couple times where the bikes he tuned got on the street and when the rider got on the throttle, the bike just bogged down).

Personally, if I can find somebody with a good reputation that's willing to accept my input, rather than arrogantly telling me that he is God's gift to the dyno, I might consider having it done. As it is, I'm running a map for an M4 exhaust and it works ok, besides being a little sluggish off the line. Last time I checked, there were at least 10 maps available for my bike (not counting European model, not sure what the difference is) so it's just a matter of seeing if any of those act any better.

If there is a good tuner in the area that has a dyno and an exhaust gas analyzer it can be worth it if he wants to take the time to tune all areas. Far too often all anyone tunes is the 100% throttle range which is not where we ride alot. Even while on the track.

I'm going with the Wideband Commander after I do Jennings GP next week, and then I'll be adjusting on my own.
