in my experience, the engine will run with the CMP off by 36*, but you can tell it is not running it‘s best and it will set the cel. this was because I installed the new dizzy gear 180 off. was able to dial that back in at a nearby shop that had a scan tool in short order. another time, I swapped the crank sensor, for no good reason, it really ran like crap, put the original back in and all was good. don’t remember if that set the cel light.
maybe these guys that have swapped 0411 and black box back and forth can share engine reaction on startup and if you can hobble to a shop with a scan tool and knowledge to do CASE relearn
