Link will switch maps when the EGR or FP solinoids are active. So if you are running the Meth pump with your egr valve... It will change maps accordingly.

Now mike. With Link, the EGR solinoid /meth relay.. Can be programmed to de activate at any count of knock. There for instantly changing the map back to something more conservative. So if anything goes wrong with the meth set up.. Clog, leak, empty tank... As soon as the car knocks.. It can pull timing and add lots of fuel. Can you do that with the evo Ecu?

Also with the DSMap set up. I believe they actually used a electric 5v pressure sensor on the meth hose. Warewolf could take the voltage and react to anything under or over spacific meth pressures and alter the tune to save it. I have not found away for link to do this with its limited input control.. But maybe then evo ecu might be able.

If you know what Im talking about.. Lal
