do I need the Fuel Pak : V-Twin Forum: Harley Davidson Forums

Steve H · 09-16-2009, 12:49 AM

HI all,

I recently put on V&H classic slip on's with the Fuel Pak, and stage one kit (Arlen Ness big sucker) on my 09 FLHT........I love how responsive it is....my question is this......my wife has an 08 Nightrain, and her son and I put V&H short shots on it for her......can I just do the stage one to get a better air fuel mix, or do I need the fuel pak? her bike runs good now, and since I am new to this, I don't want to damage her bike, and want to know if it would be ok to do the stage one first then the fuel pak in a few months.....

thanks guys....

Steve

are you talking about getting the stage 1 down load from h-d??? if so theres no need to do that if your getting the fuel pack.. you should get some kind of fuel prosseser.. t.b.h i would get a pc3 or pcv.. those units have alot more adjustablity.. i hope this helps

I have the Fuel Pak on my bike, and are very happy with it, being that the funds are tight, I wanted to know if it would be better to get the larger air cleaner (I have the Arlen Ness big sucker on mine), first, then get the Fuel Pak a bit later........

you should wait till funds are good and then do bolth at the same time..if you do the big sucker with out the fuel pak the bike would really be running lean..

thanks for the note....will do......her bike seems to run fine now....but after doing all to mine (pipes, FP and air kit), I want hers to run as efficient.....

Thanks

Your thinking is fine, won't hurt anything. The stage 1 down load doesn't do much for fuel. The Fulepak will make it run cooler as their all so lean from factory because of EPA standards.. Good Luck

Steve H...Before you pull the trigger on the fuel pak...Be aware that your 08 and 09 bikes have some great technology that you can utilize to get the best runnability out of your bike and IMHO the fuel pak would not be the way to go...TTS Mastertune is, again IMHO, probably a better choice. I have seen some very poorly running bikes using the Fuel Pak and have had nothing but good response with TTS's product. The ability to use a tuning devise that actually modifies the tables within your ECM, rather than adding the Fuel Pak module(another possible failure point), is priceless. The fuel pak is a signal modifier that takes the stock signals from the ECM and modifies them to give you more or less fuel as needed... The Mastertune allows you to modify all of the neccessary tables in the ECM to get your bike EXACTLY where it needs to be based on YOUR engine's needs...It will be neccessary to optimize the VE tables for the best runnability of your mill and that simply cannot be done with a fuel pak. It is in your best interest to use a tuning devise that actually works WITH the adaptive learning that your bikes have, rather than against it...
Just an opinion...hope it helps

Student; FuelPak is relyable, works very well, can't say how it compares to others but it's a good unit to buy.. I don't have stock in V & H's.. I read a thread about Fuelpak, it's here on this site. I'll try and find..

good advice

Out of all the things out there I believe the TTS is the best so far.

Jeffytune · 11-09-2009, 02:38 PM

The short answer....

YES

Ok, a bit longer answer, weather a Fuelpak or other device should be used anytime you increase airflow through the engine.
I see no upside to having the "Stage one" download installed, as there are programs in for the Fuelpak for with or without.
Seems like a waist of 150.00 dollars to me.

And my opinion as well based on the number of enricheners we've removed and replaced with PCs/SERTs/SESTs/and Matertunes to properly tune fuel AND timing for changes.
From our experiences the enricheners work OK for stage 1 bikes but that is where it ends. Once cams and/or heads, or V&H pipes have been changed the engine needs to have fuel lessened in places as well as enrichened in others.
The enricheners will make the engine run cooler simply because they use more fuel to cool the combustion which, in turn, usually loweres power in places where added fuel wasn't needed. Usually timing changes will make better differences than simply adding fuel, and in some areas where added fuel is not required/wanted.
