Re-Mapping - Sportbike Addicts

Does anyone know if you NEED to remap your bike when you get a new exhaust. What I hear is that you can lose hp if you don't remap. Personally, I got a pipe for the sound not performance.

From what I've read, you'll NEED to remap if you put a full exhaust on. If your bike is FI and you have a slip-on, the CPU should compensate for the pipe.

don't believe that dude. there's no jap bike efi system i ever worked on that compensates for anything. they're not that smart. It would at least need a mas airflow sensor and a wide band o2 sensor to make any kind of realtime duty cycle adjustments.

the honda ecu's , for example, have 3 stock maps in them. when you cycle the system(turn the key on), it takes an air temp and barometric pressure reading then picks the best map to run on until the next time you cycle the key.

the zuk ecu's are programmable though. Factory pro has a programmer for them if you don't want a powercommander.

IMO, if your plugs look good after a hard ride you're runnin fine.

Ok, that's cool. However, do you think that a remap is necessary even with a slip-on? I don't think air/fuel would be drastically affected with a change like that.

i think its bike dependent. for example, Ron at WCW told me that 03 R6s make the most power with the straightest curve using a graves full system and a stock ecu. . now as far as being balanced by way of air/fuel ratio, thats another story. i mean, if it was running severely lean it wouldn't make optimal power, yknow?

Well i knew this would be the best section for Xenos.

Seriously though mapping and PCiii and all that become a tricky situation. Ron at WCW says most of the times the maps hurt the bike over helping them. Also like Xenos says, "There is no way that they took a bike and put every single pipe on them to make a map" which is true.

When we did mine we ran a stock map over a Micron map for my f4i
