0411 swap on 99 Vortec 454

[N0DIH]

Got a RR question. I am looking to finally get an 0411 PCM in my 99 Suburban K2500 454, and use my RR and EFILive to tune it.

DOES EFILive support the 5.7L L31 Van code used in the 0411 for this swap?

I have Tunercat, so setting it all up there is no problem, but I want to use RTACS finally for the first time....

Thanks!

It works fine in my RoadRunner.

The L31 from 01-up doesnt' show as a supported OS on EFIL's Supported Vehicle list, that is why I was wondering.

What OS are you using?

The '02 L31 Express Van uses the same OS as '02 Fbody/Ybody (12212156)

Ahh, ok, cool. Didn't know they used the same.

I hope to do my 0411 swap in the next week or 2. I have the itch... Just something I have been wanting to do, and it is getting warm out too.

And after that, will ponder CNP ignition, but that is a later project.

Sorry I was not specific about using the 02 OS. It does take some tuning to get it in the ballpark. The Van air intake is restrictive.

Thanks! I'll be working on it here shortly, got laid off and now I can let my wife drive the SC3800 Park Ave and I can stay at home and mess with the Burb....

I think the 2001 Operating system will work the best for your situation.

Can anyone here utrn this into a .cal file for tunercat 2? I cant get the o411 swapped 454 to start and idle very well in the RV. Used Lextech's pinout. Turns on, scans with datalogger and reads via snap on scanner as is supposed to.
