COS5 Help

[mikeyayell]

I am wanting to use this OS. How do I get the tune I have now on that OS? Im just wanting to use it for the ease of nitrous use.

Thanks

You have to copy all your tables over to 12212156 (2 instances of the tune tool, copy-with-labels from your tune, paste-with-labels into 12212156, do each table table-by-table)...

It is a little tedious (about 2 hours worth), and there may be a few tables that are transposed... but once you have done it (and verified that your car runs on 12212156), then the jump to COS5 is simple.

It also depends on what year/model you're starting from... www.holdencrazy.com has two stock 1999 F-body 12212156 migration tunes;

if you're starting from a stock 2001 F-body, then you can just full flash 12212156 without copying any tables... (or just copy over your modified tables).

Mine is 1999 on an 02 OS.

holdencrazy has a 1999 F-body 12212156 migration tune,

you can just copy your modified tables to it.
