I have an aftermarket stand beside ecm that offers virtually unlimited flexibility. What ever you can dream up it can do. That being said what I am doing as a fail safe could be done without the extra ecm. I have my ecm set up to open a pair of relays that apply power to the factory coils. if I am above xxxkpa and above xxlambda on the wideband it will cut power to the coils. This could be done with a boost switch and a voltage switch hooked to the wideband.
If I ever move my ignition over to the new ecm there are a number of built in failsafes that could be enabled without an external relay. I would also gain a 2 step but loose tq mgt but I was thinking about ways to incorporate that back in.
