2000 LS1 to 2002 LS1 OS

[mikeyv]

I've got a 2000 Camaro SS and I did a write entire to get a 2002 operating system but the 02 OS I downloaded has the 1 Bar SD mode applied and I was wondering if I could "un" apply it because I want to run my Maf. At the moment it's back to my original operating system because I was under the impression that I couldn't use the 1 Bar SD if I'm running a Maf. I can't test this to see if it would work right now due to my interface being repaired. It should be back this week sometime but I was wondering if anyone had any insight on this. Would I be able to un-apply this then do another write entire? Thanks for any responses and your time. Mike.

Get a stock file and load it. You can't un-apply it.

That's what I thought but I don't have any more credits to get another 02 operating system.

Can someone post the specific differences between a 2000 and a 2001/2002 operating system. Is there a chart somewhere showing the differences?

[Bill@HPTuners]

There are hundreds of changes even between 01-02 calibrations, the one major change from 00 to 01 is the lack of a secondary VE table in the 01+ calibrations which makes them slightly more desirable over the pre 01 cals.

So Bill, is it worth it to flash in a 2002 tune into my car? I've got 4 credits still unused, so it's not a big deal if it costs me 2 credits. Also, I realize that now my VIN would be changed, would that be an issue?

FYI, I'm excempt because I drive the car less than 5000 miles a year, and it's actually closer to 1000 miles.

I still run the 2000 OS in my car. Only reason I would change is to setup the IAT bias, but I pulled my IAT sensor out anyway.
