Plz note this is the development thread. The current version of this OS is v5. You'll have to learn about tuner pro, xdf's, and bin files. If you have the time to read and learn it's well worth it for p01 and p59 PCMs.
Here's v2 with a link to v3. V4 and v5 are on Brandens patron link in the threads. V3 and up are only for p59 PCMs.

You guys need to look into the open source type of tuning and OS. Anything is possible. Boost control, nitrous control and 4 bar map as we speak.
WBO2 closed loop dual bank, etc
Edit.... Launch control as well as boost timing up to 4 bar. The cyl air is nothing that matters with this. Read up with the links provided later in the thread and if there's questions I'll do my best to help.

Once you try and get that fancy with a stock PCM its almost a no brainer to go with a aftermarket ecu thats designed to do all that.
I install Dominator ECU's in 75% of the builds these days to make it very simple and have it programmed with all the safeties needed.

Ya I can see that. The thing is this costs nothing. It's something that you have to want to do though. I've been hacking PCMs for years so it's part of the hobby for me. If you have the money and no desire to look into it then that's perfectly fine.
