Greetings all,

Other than a call to Vance and Hines I figure this is the best place to find the answer, since there is such a huge knowledge base in the HDforums audience. Does anyone know if the V&H fuel pack compensates for altitude like the stock ECM does? Planning a trip in the near future and haven't been much higher than sea level (live in florida and find a parking garage to be entertainment just because of the ramps)since I did an upgrade.

Thanks

 

The stock ECM will do the compensation. The fuelpak is just a piggyback to augment the stock fuel curve.

Pretty much a bandaid for a proper tuner. If i was to do it again I would, at the very least do a PCIII but should go right to the SERT.

But to answer your question. You will be fine. Stock ECM will handle the little differences needed. The fuelpak will just add fuel to the ECMs values.

 

Sorry, I can't resist after looking at your signature,

You are incorrect Donk....

The fuelpakwill justsubtract fuelfrom the ECM's values (as you increase altitude).

 

lol!

I dont think so... The fuelpak has no way of "knowing" what the hell altitude it is at. Its only input is injector "timing" (cant think of the word) and throttle position.

The fuelpak has fixed values... the ECM is the one doing the adjustments and the Fuelpak just adds to the ECMs outputs...

The numbers arent the important part here... the equation is.

Such as:
ECM at 0 feet altitude = XX @ 2500rpm + Fuelpak setting of 5@2500pm = XX+5
ECM at 2500 feet altitude = XXX @2500rpm + Fuelpak setting of 5@ 2500rpm =XXX+5

The ecm is the one adjusting... the fuelpak just adds enough fuel at the preprogrammed points that you "dial in"

 

Oops,

You are correct (again)Donk....


The ECM is subtracting fuel for elevation, not the Fuel Pak.

I was so excited about getting you a new signature that I didn't read your post correctly, talk about a backfire.

 

Hey buddy no worries... I edited my sig just for you too!

 

Great, just rub it in. Beware, your posts will nowget extra scrutiny.
