I currently run a 12205612 OS. I need to go to a custom OS for a 2bar tune. CLSD I am thinking. I am maxing out my maf at 4200 rpm and 65% thottle. Now for the questions:
1. I need to change year of OS, so I am guessing 12212156 OS needs to be used AFTER I table by table swap my tune into the 12212156 OS? Any shortcuts here??
2. How do I decide if cos3 or 5 is right for me?
4. I am thinking at this point I can follow the tutorial for upgrading to a cos ?? What did I miss?
5. Since I am currently running a tune someone built me long ago, I assume it would be smart to do the autove before starting this so my fuel will be close or is that just double work since its not to far off now?
