Right then. So i'm gunna start using race fuel in my race bike but heres the catch. I cant afford to use it all the time. So i'm gunna just use pump fuel for the practise then use the race fuel just for the races. So heres the question. I'm gunna get a custom map soon, so do i map it to pump fuel cause thats what i will mostly use as practise is all day saturday. Or do i map it to the race fuel. What are the pros and cons of doing that. If i map it to pump fuel and just add the race fuel for the races will that make much difference. Or if i map it to race fuel will it run like poo for the practise's. Any help would be great as i'm clueless in this area ( as like all other area's)

My .02, get mapped for race gas. When I switched to U4 I had 2 maps made, a U4 and a pump gas. The U4 was good for 4 more hp. I think (I am not an expert) you will be running a little rich on the pump gas which is not real bad. Also, if you are planning on running U4, you may want to wait until the new U4.1 comes out and get the map done w/ that fuel. Not sure when the new fuel is comming out, but it is.

I think U4.1 is already out. It's suppose to be da bomb - a bit more power, but much less harmful shiat (no need to drain tank after each use).

Tony like the man said

why not get 2 maps and change it at the track side using your lap top. then the bike will be perfect what ever you run.

just remember how to turn it on or youll look a ****!!
