They didn't even look at my ECM as it was behind my glove box. I passed without a california prom (ARJT) as the visual inspection was the more complicated part. What I've noticed about the California proms is that all the timing is taken out and there is a higher EGR duty cycle. The only way I see the prom being an issue is during the sniffer test if it has a higher NOx reading, but even the leaner higher timing prom I used passed.....

For the OP
-Just keep all the stock sensors (I wired in a 3 wire O2 sensor that the smog ref liked seeing)
-Get a Catalytic converter with the EO for the engine you're using
-You need a VSS sensor with an EO like Jags that run https://jagsthatrun.com/collections/speed-sensors
-Get the charcoal canister from the vehicle you get the motor from
-Get stock exhaust manifolds or headers with an EO
-Use the Stock air cleaner from the engine you're using
-Have the exhaust done at any california exhaust shop and they'll take care of the exhaust issues.

It really isn't that hard to get the engine Swap done and accepted, maybe it was my local area that made it a little easier, but it really isn't that bad.
