Thread: Titan fueling adjustments

    Titan fueling adjustments

    Hey all, well versed in GM tuning but have a Titan I'm playing with.

    I have some some searching around online through ecutek and uprev documents, as well as poking through files and think I have a decent handle on this... but I'm not totally sure.

    I'm assuming the MAF is the main fueling control here, and the VE tables are more of a sanity check or transient adder. What makes me question changing the MAF is the relatively low airflow limit for the table (256 g/s), doesn't leave much room to up the table.

    Next there is the fuel compensation main table, which is load vs rpm. Reading an UpRev file, it talked about this being the main fueling adjustment table. Makes sense, just seems like a strange way of doing it.

    Is one way better than the other?

    I have no help to offer here.. but i have a friend with an 08 titan that want's a tune so I thought i'd check into using my hp tuners instead of him pay $600 for a mail order tune or whatever it costs. So I'm curious about this.

    Would you mind posting up or emailing me the tune file you have? I haven't upgraded my MPVI to the new version yet so i can't even read his tune file to get a feel for it. cjsteffen92@gmail.com

    You can't open the file without an MPVI2 plugged in

    I've had my 2011 Titan tuned. (Once on the dyno, other was revisions made online by a fellow I met on here.) Would either of you like to see a copy of the maps?

    I'd certainly take a file if you wouldn't mind. cjsteffen92@gmail.com
