Hi,I have a 02 GSX-R 750 with a full graves exahust,pc 3 R and a tre. Today I tried out all of the maps that came with the program there are 4 out of the 20 or so maps that say for race use only and they all say to use nutec or nutec 4 nutec 5 or nutec specail (depending on teh map. 2 of them have the stock cams degreed at diffrent numbers. 1 of them has the cams deg and the timing changes in the map ( the only one out of all the maps that have this) I tried the map with the timing changes with and with out the changes. My ? is will any of these maps hurt my bike in any way? they seemed to make the bike run better. Pros cons? I don't want to blow up my bike. Thanks

Any ideas?

Detonation can hurt the bike. This can happen from a lean condition or low-octane fuel. It's possible that the 'race-only' maps are intended for use with 110 octane race fuel. If so, then the timing might be too aggressive for pump gas. but I'm not familiar with the PC fuel maps so I'm only speculating.
If there's no detonation and the map isn't so rich that you are washing down the cylinder walls with fuel then there's no other concern.
I'd call or email tech support and ask them if either of these issues are a concern.

Would I be able to hear Detonation? I know what it sounds like but i was wondering if I could hear it on the bike?.

Yes, if you've got a good ear you should be able detonation. If you hear anything abnormal coming from the engine, I would change the map asap. If the bike is running good, and there's no detonation on the top-end(where it's most likely) then you should be fine with that map though. You said the bike ran better with that map, so I'd say stick with it as long as you don't hear any warning sounds coming from the engine.

the mods you listed is still stock...as far as i heard its a waste of money if you use just (race) gas if you haven't custom map your bike for it and done internal work on that engine..also those free maps are good but they are not precise..save your money get it custom map especaily since you have a full exhaust and pc...the free maps are general or specific to the bike that was dyno/mapped for that only bike so your bike may be running rich or lean on yours...which results in sucking up more gas and have hiccups on the bike..i have the usb and that good for me but if you plan on going to the track then you will use pc-r .....i don't think it will harm your engine if you advance timing as long as it not detonation but what will happen if it not timed right you will not get full power(full potential of your bike) unless you custom map it...again i am not a mechanic nor a pro..just my .02
