Getting a strange "dieseling" effect when I shut off my car.
Stock computer, stock coils, br7ef plugs, front mount turbo, ect
When I go to shut it off(just idling) it has a small sputter and halfway runs for a second when I shut the key off.
Didn't do it n/a, all the same electronics, car is untuned but I don't think that would make a difference, it should kill it w the switch no matter what. Seems like maybe an electrical issue bc the gauges kinda bounce when I shut it off. Like when the battery goes low

Possibly be the crank or cam sensor? Both worked when I pulled em out of the old motor.
Could it have anything to do w the pushrod length??

Electric fans? Depending on the fan and how its wired I have seen them backfeed while spinning down. I know you said everything is the same. Its just a thought. When you say kill switch do you mean a battery disconnect?

It has electric fans, they're wired thru the factory harness, so I figured that'd be fine. Although, they are push/pull, so they might have the effect on it. I will have to check, but I'm pretty sure it does it even when the fans are off.
Although it could be doing it bc of the trans cooler fan too.

Basically yes, when you turn ignition off the lil wire that plugs into side of the alternator kills the diods which turns the magnets of inside, which should kill any power trying to be put out by the alt.
My dad had a old truck that use to diesel forever, like to the point we had to pull the coil wire to kill the truck.
