Hi all.
i have a P01 controller for LS1 that at this present time has a speed destiny RTT patch applied. i am looking at upgrading to a 2 bar operating system although this is not available in the OS tab.
i have read around and seen some people using VVE editor for your primary VE table. where do i find this? Tune file is attached. using 3.4.55.0.
thanks in advance.jamie statesman 2bar.hpt
All custom OS have to be applied to a stock OS. You can't apply a COS to a COS. VVE is for Gen 4 PCMs like E38 and newer. Not applicable to P01 and P59 PCMs
What he said, revert back to a the stock OS and see if a 2 bar is there.

If you don't post your tune and logs when you have questions you aren't helping yourself.
Im using the 2bar os on a P01 works great but it must be written from the standard OS to begin with
great thanks guys, next simple question, how do I revert it back to stock OS?
You have to have it to do it.
Hopefully you saved your stock file somewhere or can get it. Without it you are pretty much boned.

don't have a stock file as this pcm had already had patch applied, looks like new pcm to carry out work.
can i flash a stock file matching this PCM back into to revert back?
I would not do that. You'll end up bricking the computer more than likely.
Besides you'd have to license that file just to do that, then brick the computer. So you'd lose twice.

ok, think i will go new PCM. thanks for the input guys .
There is no reason you would brick the PCM if you are writing entire a stock calibration that matches the one in the PCM sans the custom OS. You will have to license the file you are writing to it, but you will have to license a new PCM also. And new PCMs are usually blank so you would have to pay someone with dealer type programming tools to program it before you could use it. I program hundreds of PCMs every year, many with write entires changing vehicle types and OS and never brick them. A little more information on the vehicle would help.

You may have to deal with the VIN as well. But only if it's a car that needs to pass emissions.
