I wired in a temporary switch to turn the esp system full-off so that i could easily switch to dyno/race "mode". of course the abs system goes off line as well, but in any situation i should be shutting the esp all the way down i shouldn't need abs anyways (and i'm not likely to forget since it will be flashing all those lights in my face).

i'm planning to make it permanent as soon as i find some aftermarket switches that i like (or some extra benz switches).

I am trying to find a way to literally "switch" the car into full open loop as well. Under cold start the car runs open loop so if i can figure out what sensor the car is using to determine that it is cold- i will be able to wire in a resistor to emulate that and have that be switchable as well. This would allow me to truly "tune" the car using my maf scaler to a higher degree. Anyone know what tells the car it's cold (with this application in mind?)

thanks
