Default migrating to 2002 OS...

Ok, deleted the other thread after some searching on EFI live website.


Here's what I did...

I took a 2002 LQ4/4l80e stock tune and did a transmission segment swap from a 2002 4l60e tune. And I also put my VIN in that tune.

Should it be all good to go now?

Only thing is, the only 2002 60e tunes I could find were with 4wd's. Will this work okay with me being 2wd?

Thanks!

Well, it started up and ran. The stock lq4 tune is soggy as ****, but that's another story.

When I start it up I get a change oil message, which goes away and then a constant battery sign that flashes in my message center????

I had EGR codes (turned it off), and also a P19xx something I think.

I looked at the log and it's still all screwed up at wot. Honestly got no clue what's going on. I did notice that in normal driving I didn't have KR like I did before.
