    Well I Have updated to the custom OS following the EFI Tutorial manual. Truck wont start, seams like it wants to but no Go. Smells rich when cranking. EFI tutorial said it is a good base map. Is that true. Any advice?
    Thank you

    Did you fix up table B3647...?

    Did your engine start and run on the GM tune...?

    Post your tune file.

    Hello Joe. Sorry I had to disappear for a few. My truck is all complete and had it running on a bad tune of course. As per your directions I was able to upload custom map and follow efi live instructions. Now the truck wont start. Tuning is all that's left so I am back on this project. will post pics as well as the tune file if you are still interested to take a look.
    Thanx again

    Look at table B3647, does it contain the data from the old B3605...?

    Post your old tune (before COS upgrade) and your current tune (after COS upgrade).
