#4933, "RE: MSnS Emissions Question" In response to In response to 0
The Megasquirt does not care about any emissions devices, it's not an OBD2-compliant controller. it also has no provisions to even turn on a CEL.
However, you're gonna have the CEL on with an MSnS, unless you completely remove the stock ECU. Get used to that fact and accept it.
