2012 ultra problem after cam change

[bobrk1]

A friend  has a 12 ultra  it has a  Vance and  Hines fuel  pack  he installed  a s&s cam not  sure  which  one , seems  ok cold was running  good  he stopped  it stalled  wouldn't  idle  after  starting  ran ok with  rpm up bring  it  down  ran bad like  2 different  bikes. Ran fine  before  cam  maybe  just  a  coincidence , anyone  have  a  problem  with  v&h fuel  pack ?

Was the Fuel Pak reprogrammed for the new cam?
If so, has the owner contacted V&H to get a different map?
Those tuners are not tuneable, but only have preprogrammed maps.
Ideally he should get a different tuner and have it Dyno tuned.

Did you try disconnecting the fuel pac ?             Coff 06

Disconnect fuel pak or make sure has correct map and if that does not help check that the cams inner dots are timed correctly

Disconnect the fuel pack and tell him to get a better quality tuner that isn't a piggyback device.

The symptoms you've given sound exactly the same as what the fuel pack 3 does when it is put into self tune mode after doing engine work. Stumbles, stalls, runs like crap...

Disconnect the fuel pack and tell him

& tell him to throw it in the nearest trash dumpster (or sell it to somebody he doesn't like) lol.

Just curious, by computer do you mean the bike's ECM or the FuelPak itself...?
