    I am just curious how you would make stoich 15.7..
    I was thinking B3601.

    I've just disassembled my T-56. Wow, for a transmission that had no noticable problems but had 146,000 miles and was a little notchy, It sure had a lot of parts that need replacing. Mainshaft, 5-6 cluster, 2nd gear, 5th gear never mind I already bought $900.00 worth of bearings, synchros, sliders, hubs, steel 3-4 shifter fork, billet keys etc etc.
    So why mention it here? It will be a little while before tuning is anything but a mental exercise.

    No, I understand Ed.

    COS have always been a challenge to those of us running 'Regular OS's'. I suppose if that portion is Open-Loop, running leaner is an option.

    Its always intriguing how you can optimize Closed-Loop and Open-Loop easily in a COS.

    I would likewise be curious to see actual Logs accomplishing exactly what you are describing..not just hearsay...

    Ed, if you're running COS3 (which is based on 12212156), then you might give the lean cruise cax file a try (rename 12212156.cax to 02020003.cax)...

    this will be mentally easier than faking up the stoich AFR and the NBO2 switchpoints.

    COS5 is also based on 12212156. Rename 12212156.cax to 02020005.cax.
