    One option for a .cal file, if you have a VIN # is Tuner Cats, http://tunercat.com/obd2/calfiles.html

    I've used Auto Trader to find VIN #'s

    Im a complete noob. What would i then do with the .cab file? Can I get that onto my mefi?
    That site looks like a scam too. Theres really no contact information or selection except a link to paypal asking for $25.00.

    I'm tuning an LS3 engine not a car, the engine is going into a boat so I have no VIN #.

    Oh, I was thinking you were using the Factory GM E38 ECM on the LS3. Most members here are automotive, so I figured without a post indicating Marine, I figured automotive .CAL file format. The .CAL file format WILL NOT WORK with MEFI.

    Not that it matters anymore, here is the complete link to TunerCat, http://tunercat.com/ (Scam - HELL NO!!)

    Try this link for MEFI: http://www.aldlcable.com/

    Thanks for your reply,
    The automotive tune would work for me. I need an XDF file.
