Probably not one of the smartest things I have ever done but, hey WTF. Anyways I own an st2 and a 916. I had to order a new ECU of fleabay for my ST2 and it came with the Ultimap EPROM chip in it (chip says Ultimap /ST2). I had my 916 pulled apart and decided to throw the ST2 ECU with the ultimap chip in it on there and I started it up. The thing feels like it is on Steroids now - Serious power increase. The 916 has carbon fiber cans on it, dont know what brand, rest of the exhaust is stock. Do you guys think this will F - the bike up if I run it with the st2 ultimap chip in the 916? I may very well be retarded for even trying this so feel free to confirm that as well.

As Tom says (He tunes bikes for a living) the fueling should be lacking at high RPM´s.

I´m guessing that the ignition map on the 2v 944cc watercooled st2 engine is abit diffrent then the 916. That may be part of it. The other part might be your "seat of the pants" dyno. If the power comes suddenly after the map has been seriosly wrong just before the powersurge, you often get tricked into thinking that the bike is faster.

Tks for the answers guys, I am certainy interested in tuning this thing properly if that is the case. Do you have any suggestions as to what set up would be best? ( I do all of my own work mechincally, but have not really messed with the ECU/computer side of the bike) so would be looking for something that I would be able to learn fairly quickly. Tks again !
