EFI LIve 2 step function I posted this on the EFI live forum but thought it may get more response here
I didn't realize until yesterday that there was a 2 step function on this program. Anyone here that uses it? I haven't bought EFI Live yet but I think this just saved me some money on a 2 step controller and/ or a transbrake.
Is it used just like an aftermarket controller and how would this work if I also drive the car on the street? would I have to go back in a turn it off..I guess?
Thanks

it's a switch that you have to wire in and works in a custom tune so you will need the comercial version to install it. I have not used it yet but will try it this year. I was thinking about installing it last year but it was called a valet switch then now it can be used as a two step so tha's cool. I

loks like it may not be right for a racing setup 
Problem is, it uses the factory fuel cut routine, not spark cut, so no staging duels as it leans out pretty bad.

Remember, an SI combustion requires air, fuel and spark. Take away one, and you're left with... the other two.

no fuel = no burn in the exhaust... no burn = slower/less turbo spooling...
with a conventional 2step, the fuel ends up burning in the exhaust, so the volume in the exhaust is still like WOT, keeping that turbo spooled up good..
this 2step only sounds like a solution for N/A guys.. mostly manuals, but i suppose someone with a large stall and a transbrake could use it to launch from a less then true stall RPM...
