I was reading that putting a Fuelpak, or other management system, works good for the fast gain. The article went on to say that the aftermarket systems causes the engine to build up carbon deposits. Is this true.
I have a Fuelpak on my UC and it has been working great with the map. V&H technical group does enough research to make sure the maps chosen work well without damaging your engine. As for the Power Commander, you have far more flexibility to set your own mapping and can screw it up more. The Fuelpak is straight forward and the maps are set via V&H requirements. I average about 42 mpg and I am heavy handed on the throttle.

Over all runs great but won't get much better then 35-36 mpg either.
So do you have to dyno tune to increase the mileage?
I'm not paying that money for a Dyno tune. I don't think its necessary, I can livewith what itsdoing until I put a DTT fuel managment witho2 sensors onthe bike.
I'm sure a dyno tune would perk it up some but with a dyno tune why would Ineed tohave a fuel pac? That kind of money isjust like doing SERT or a PC III in my book.
And double that money in mostcases you have the DTTpaid for and still never need dyno's again, except for bragging rights!
I read through that article awhile back- as I recall they were wrong in that they said the V&H Fuel Pack & PCIII required the removal of the O2 sensors, which could cause fouling in the cylinders due to a too-rich condition at low rpm.
I know for a fact that Fuel Packs retain the stock O2 sensors (not sure about PCIII's) so in that respect they're feeding bad information- maybe to entice potential buyers to drop $400 for their wideband O2 sensor setup...
That's the kind of stuff I was referring to when I said some of the information was dated and that it was incomplete. Nowhere on the site is "adaptive fuel" mentioned and this is a very capable form of auto-tuning evidently brought over from the Buel camp. I don't know precisely when it was implemented but the '07s have it. The LC-1 and even their resistor network voltage divider would mess up the open-loop running areas of the engine as a result of the adaptive fuel feature.

SERT, DYNO= $810.......Peace of mind and running like a raped ape, priceless...
If you have a $20,000+ scooter, what's another $500 to make sure it is professionally tuned..
Ram,
To my knowledge, you can't dyno a fuel pak.....you would need a PCIII or SERT and you're right a fuel pak would be useless....just sitting on the work bench at that point.
I only get 36-38 mpg on my '08 EGC. it hasn't changed with the addition of Rush 1.75s, SE A/C and SERT. It runs better and cooler now, but mileage still sucks.

True, with a dyno tune no need for fuel pac!
So saving the SERT and Dyno of say $810.oo thats amost what you would pay for a DTT with o2 sensors.
This is true, and the DTT will provide controlled feedback of the operation throughout the operating range whereas the SERTed Delphi will be acting on blind faith (though when dynoed it's a fairly sure thing). One thing in the Delphi/SERT camp that is a benefit is its use of the MAP sensor in all of its calculations. The DTT, I believe, only uses it for timing, not fuel (but then it doesn't really need to since it's using the O2 feedback loop). In the end, if components aren't going to be changed after the initial setup it's a wash between the two. Decide to change something later, however, and another dyno session will be in order for the Delphi/SERT...
