is it nessasary to dyno tune my 2007 injected harley if adding pipes and hi-flow air filter?
if i'm computer ( microrocessor ) controlled, why does my dealer say dyno is required or it wont run right.my other harleys have been carbed,so change in elevation would require tuning or jetting. seems my 2007 96 inch fuel injected computor controlled should remap it's self to achieve max. gain. they want 300 smackers to remap and dyno. line me out here as i have never had a computor bike and sure dont want to meltdown a 20.000 dollar investment. thanks to all
Adding performance pipes & air filter does not require dyno tuning; they are low-end performance parts. You'll have no problems.
no, don't listen to them.
Dude, the bad news is that they are probably right. Most computer controlled motors have enough adjustment space in the program that minor changes (humidity, spark plug wear, air filter flow reduction over time, elevation changes, etc.) can be handled and adjusted for. Unfortunately, a major change that affects the performance of the motor (new increased flow air cleaner, low flow exhaust, change in valve timing, etc.) might require some recalibration. In some vehicles this is done by swapping the computer chip; you can often "do it yourself" if you know what sort of program you want. I'm not sure how the HD system is set up, but I'd want to get it in the hands of someone who has experience modifying and hopping up those HD computers.
Be warned: just like any hop-up mod, you can put a lot of stress on an engine this way. If you build up the intake and exhaust system, but are putting this load on stock bearings and cranks, you may find that your motor might not last as long as you thought it should. Good luck.
My 2005 Fuel Injected Meanstreak has a PowerCommander III USB and a set of Vance & Hines Big Shots Staggered pipes. I still haven't decided what my intake upgrade will be but when I do I will MOST CERTAINLY have it dyno-tuned. What's the point of spending all that money buying performance upgrades, all that time installing them and then not having them set-up to deliver peak performance. Yes, I will agree that it is quite expensive to have this done but it's a one-time thing and as long as you save the MAP settings, you can re-set your computer if you ever have an issue. The only time you'd need to have your bike dyno-tuned again would be if you made another performance modification.
If you have a PowerCommander also, you can sometimes find the proper MAP on the DynoJet website to download for your current configuration. Much cheaper than a dyno-tune. Good luck!
You dont need it Dyno tuned, but you should get it re-mapped at the dealer. Its a standard thing with Harley fuel injection.
A suggestion though - if you intend more minor upgrades, get them now before you get the chip re-mapped.
If you don't know how to set a Fuel pac or power commander on the bike then….Yes, dyno is required.
I used the fuel Pac. because the dyno is not required. A simple choice.
What you've done is part of what is commonly called a "stage 1" hop up. Freer flowing pipes and more air will make the bike run stronger, but will also over-ride the factory settings on the computer for the fuel/air mixture. Remapping the computer and a trip to the Dynamometer will allow the computer to recognize the different amount of oxygen in the air, and will adjust the fuel flow accordingly.
The average HP and torque you get from the factory set up is somewhere in the low 60's, if that much. By remapping, adding pipes and a K&N filter, I boosted up to about 65HP on my Harley. After adding a DFO and a Dyna ride, I wound up with almost 72 HP and 70 ft. lbs. of torque. $300? That's what you're going to be paying for. About a 10%+ increase. If you ride in the mountains, like I do, it's an investment that's well worth it.
No, it is not necessary to have your bike dyno tuned. Harley's Race Tuner kit is able to be installed then a generic map is installed for your pipes and air cleaner. That map will get you very close to where you should be, unless you go with huge exhaust or wide open air cleaner. You may need some tuning on the dyno if the map is just not right. Be sure to keep your tuner "key" whenever you get work done. Hope this helps.
u need a computer to set the bike's computer. do u want the bike to run at peak performance, with the best fuel mileage/power for all the upgrades u did? the new bikes come to the dealer pretty lean from the factory….epa regs is the cause of that.
the dyno will fine tune everything razor sharp the first time. i'd put a power commander on it vs a race tuner tho, the race tuner becomes 'married' to only that bike, where a power commander can be used on more than 1 bike easy.
changing the pipes and air box will require a remap. that's mantra. u dont want to lean it even more than it already is from the factory. if u want the ultimate results, u need it dyno'ed. there is a saying that u'll find out to be true: do the job half-assed, expect half-assed results. it will be cheaper in the long run to set up everything right the first time.
I have an 07 Street Glide and the answer I got on this was to have the ECM chipped or at least reprogramed for the new pipes. Bigger free flowing pipes mean better scavaging and can make it run lean. The ECM has no sensor for back pressure so it cant remap on its own.
You're gonna get a thousand different answers for this question..the question you should be asking yourself is….Where do you plan on having your bike serviced?….if you spend the extra 300 for the dyno now and the bike acts up….the dealership is going to have to stand behind their work….if you decline the dyno and lets say for example …your shiny new pipes get bronzed and look like crap…all they're gonna say is…you should of had the dyno…and your gonna be stuck with a shitty looking set of pipes…..what's gonna cost you more….another new set of pipes and the dyno or just the dyno…invest in peace of mind.
I'll answer your question with a few questions that once you answer them then you will know what to do.
If all you plan to do is the Stage 1 to the bike, then get a remap and you will have many years of happy biking.
If you plan on upgrading the bike later to the 103 kit, 110 kit, or the 113 kit then go ahead and get the race tuner with dyno it will be cheaper in the long run when you upgrade the motor with race tuner already installed.
If you plan on putting a fuel pac, power commander, or some other aftermarket system on the bike then be forewarned that this does and will void the factory warranty on the bike.
Now its your choice on what you do.
