Hello,
I'm looking at finally jumping fully into the EFI world and leaving the carbs behind. Will be needing help with this. Current project is to upgrade my 1996 c1500 to a 411. Then continue with upgrades from there.

Problem you are going to run into is California smog with that upgrade.

If the engines and smog equipment are the same in a 1996 C1500 as the 2002 Express vans, shouldn't it be easy to get the upgraded PCM approved since it is going newer? Has anyone tried taking it to a referee station?

I don't have experience with a California referee station. My 1999 S10 has a L31, with the 24x crank trigger, using an '0411. I live in Washington state which has SMOG Testing. I changed the VIN number in the '0411 to match the 1999 S10 VIN #. Washington state does not tail pipe test OBD2 vehicles, OBD2 vehicle will pass the Washington state SMOG test as long as there are no emission error codes.

Does California tailpipe test OBD2 vehicles?

Does California do an underhood inspection?

Dave,
California does do both under the hood inspection and tailpipe test. What I don't know is if they would notice the change in PCM if everything else stays the same. Everything should run clean so it should pass unless he can tell it is not the original PCM. I do not have experience with the referee station yet either but I do know you can change engines and PCMs but it has to comply with the smog controls of either the year of the vehicle your putting it in or the year of the vehicle the engine came from, whichever is newer. I looked into it once before years ago when I put a Chevy 350 with a 700R4 into a Mercedes 300SD. I moved out of state just when I finished it so there ws no longer a need to smog it. I sold it then before I moved back to California.

Thanks
