    Default Vtx tuning

    I just got my vtx and I am still learing about it. I see alot of talk about gas mileage but the question I have is how far will the reserve carry you? I can fill up and get about 100 miles before the fuel light comes on. I start looking gas right then. I would hate to get caught short it's to big to push. My bike don't seem to be real good on fuel mileage. But it does have a power commander, hypercharger and hard krome Xcellerator slip on. I may to change the tuning. I live on the east coast and I can't find the map I need on the power commander page. Any ideas. I posted this on the general board also just incase someone on that board could help. Thanks

    Disconnect the Power Commander and see how the bike runs.

    Reserve should be about 1 gallon, so if you have to guess on the safe side, 20 miles. Only way to know for sure is to go out for a ride, note when the fuellight comes on and ride until the bike dies. Have a chase car follow with a can of gas to get you going again. Sorry , but there is no definate mileage answer. It;s different from tank to tank.

    You won;t find any free maps made for maximum mileage. All those free maps are more likely for maximum power, or gas guzzling. You'll have to find a tuner and have them make a map for you.

    Default Spike is right

    Spike is right like usual. Most of the posted maps are for max HP. If your in a bind while waiting for tuning time or the money. I found the Dynojet maps to be pretty conservative.

    I get a reliable 40 mpg using a near clone to a standard Dynojet map. I just had a quick dyno run (I was going to do it all, but we had a scheduling issue and I got bumped). What I did get from my limited run was a good air fuel map under load and it showed the Dynojet map to be pretty conservative (14.5 to 15:1) at cruise. Of course this is just one map, but you can learn a lot by using the map compare feature in the PC software app. Better being a little safe than going out in a leaned out blaze of glory, or an imitation of a turn of century locomotive.

    The butt meter is not a great guide for tuning, unless your fixing an idle or decel pop/

    I use a map for commuting from Bare's site from a guy named Leon. I get 38-39 mpg. I use Johnny Cheese's for fun, which makes my bike run like a monster but drops mpg to high 20's

    Default Hey Shemp

    Shemp it looks like your pretty close to my current setup. I use the 002 from Dynojet with the idle fattened up for popping. I dynoed an easy 90 SAE whp while getting 40 mpg. I do like to swap out the cruise map for a hard run map. Maybe I will get the add-on box and the manual map switch for the PCIII. are you using Johnny Cheese's "hinote" map....ever dyno it? Just curious.
