They did not, GM switched to the 8.1L in 2001.

It was never used on the L29, but I think it was used on the L21.

The L21 did not use an 0411 although it did use an earlier PCM similar to the one in say a 98 LS1 Corvette. The L21 was 24x, CNP and DBW though.

Did they do dbc on the 8.1 vans?

If you're concerned about the feasibility of the swap, don't be. My dually has one and my CCSB is about to get one, both are L29 trucks.

I've got a 96 L29 equipped K2500 I 0411 swapped. One of my favorite things I've done to that truck.

Did they do dbc on the 8.1 vans?

Those were DBW. The only 8.1 DBC setups were boats and those used the marine specific MEFI series of computers.

So what's everyone using as a base file to work from?

A mish mash of stuff, but starting with the van tune. What software will you be working with?
