To Fuel Manage or not..?
Hi Folks,
A friend of mine is in the process of buying a new softail. He is having the Stealer install a Stage 1 (V&H pipes with a Arlen Ness Big sucker Kit). The stealer has told him that he will not need a fuel management kit of any kind! They have done this on many bikes and they reckon that the bike runs just as well if not better without one.
Can this really be true. Is the stealer telling the truth? Why would he save him the $$ if not.
Will this damage the bike or the pipes in any way.
Any help or ideas with this one would be great.
Thanks
Rob

RE: To Fuel Manage or not..?
I heard all the issues with running lean without fuel management but I have a set of V & H Straightshots and a Sreaming Eagle A/C with no download or anything on my 06 Standard and the bike runs great with no problems. All I get is a slight popping on decel every now and then .....My last four bikes all did the same thing on decel running straight pipes as do just about every Harley ever made. I say if you feel confortable with a PC3 or a Fuelpak use it but I think its a waste of money as the ECU on a Fuel Injected bike is always correcting fuel to air ratios.

RE: To Fuel Manage or not..?
I must be the exception to your comments of running good. I have an 06 Fatboy that have Vance and Hines Big Radius and the SE Air Cleaner and Stage 1...it ran like crap, riding while cold was terrible and it would skip occasionally and just not run right. Dealer said that was all they could do without a SE Race Map (?) or PCIII etc. as it was just a generic download. I decided to get the PCIII because of the flexiblity and now the bike runs very good (as it should have in the first place asfter the dealer download).
So I guess I am convinced in how effective the Fuel Management system can be, although if your ride is running good, why bother.[8D]

Thanks guys,
Vettesinz : Good tip with the dyno. I'll pass it on to my friend.
Everyone else : Thanks everyone else for the advice. I had no idea that our bikes would run so well without a management system.

The ECM will NOT correct the fuel mixture on a softail. There are no O2 sensors, so the ECM has no way of monitoring the mixture. There is no way I would recommend opening up the exhaust and using a high flow air filter without modifying the EFI. You are asking for trouble. The bikes are already lean in stock condition, and will be dangerously lean if the EFI is left stock and the other mods are carried out. At the very least, he will need the HD stage I download.

Oh yes, I forgot to add I have the download. As Jamie mentioned, it would be risky if your changing the air flow and not the fuel.
