I'm gonna do a turbo setup with exhaust cut out so I want a tune for open exhaust and a different one for the closed exhaust.

What dam EMS has that option for the S2K?

I think the greddy might but I don't like piggybacks.

 

AEM EMS can change maps on the fly (you signal the nitrous map with a switch)

 

^ Bingo

Thats how I have my race gas map

 

How do you set up additional maps?

 

Use the nitrous maps as your second map, then wire up a switch to switch between "nitrous" and your regular map.

 

Hmmm, never thought of that. Cheers.

 

Greddy Ultimate has, including a switch that you can buy additionally. Plus it helps to stay smoke legal.

Ultimate is not a piggyback

 

Yes it is.

 

Can you switch boost maps too?

I'd love to have two boost settings available via a switch.

 

I would think the nitrous maps also let you change boost levels?
