Please define "nuts on". Then, please tell us how you tune the bike outside closed-loop mode without guesswork, which is >50% TP. I agree with some that 60-90% is not vitally important and a good guess is probably sufficient for most riders, but you can't precisely tune WOT with the flash-based tuners without a dyno-tune. If I am wrong, please explain how.

Is it best for everyone? What about someone with a blown bike, like the one mentioned in a recent thread here, that required a PCV on top of TTS to regulate its enormous injectors and had the ability to adjust for manifold pressure? What about someone who needs to tune for each gear, or by speed? What about someone who wants the ability to switch maps on the fly?

The truth is that there is no "best tuner" for every rider, but that each tuner on the market will appeal to different needs. Each has its own feature set and it is up to the rider to determine which is right for them.

 

You don't need to sell the PCV if you make further mods to the bike. You can dyno-tune a PCV as easily as anything else, and the DynoJet dynos that most tuners use are made by the same company. Even more convenient, you can call Fuel Moto and obtain a map for your upgrade, as they will likely have one unless your configuration is very odd.

 

Hi Bob. When I said you could sell your PC if you further your mods, of coarse I didn't mean that you couldn't dial your bike in on a dyno with the PC. I just believe that with anything further then a stage 2 mod the TTS with a Dyno is a better tuning tool. I have nothing against the PC, I run one in my bike. But this is just my opinion, right or wrong. I'm just sharing. Have a great day............Rich

 

That's very reasonable and your opinion is as good as anyone's, but there's too much hyperbolic dialog here (i.e. "my tuner is best"), with the implication that it is best for everyone. They're all good, and Brand A is best for one whilst not best for the next guy. They all have their unique feature sets and it is up to the rider to decide which is best.

Also, I disagree that the flash-based tuners are categorically superior to the PCV for even Stage III and above bikes. Why would this be when the PC is the favored tuner of sport bikers, whose engines are figuratively on a Stage X level compared to any Harley engine. Fuel Moto has tuned every conceivable level of Harley engine, including high-HP supercharged motors, and they disagree that one type of tuner can accomplish the job better than another, among the usual suspects we're talking about here anyway.

Any engine needs to satisfy two criteria for a good tune: The right injector pulse-width applied at the right time, and the PC will accomplish this as well as the others for Stage 1 or Stage IV. If not, please give me an example of why not. If this is just your opinion that's fine, but if you have examples I'd like to hear them.

 

That all make's real good sense to me Bob. Your alot more knowledgable on this then I and I for one am glad that you take the time to explain this because it helps others as myself to understand it that much more.......

 

+1 on Tmax with auto tune. I own two of them and have had excellent results. Check with Fuelmoto for good pricing and great support.

 

I have the PCV on my EGC and it runs very good. I added Vance and Hines pipes to the wifes bike and put my scope meter on the 02 sensors before I did it. I then graphed the 02 voltages while riding in normal riding situations. I swapped out the pipes and graphed the voltages again. No noticeable difference in voltage or swing. The bike is a 09 cross bones.

 

I just installed the Electronic Jet Kit from Dobeck on my 07 Deluxe and I couldn't believe the difference it has made. I also put the Arlen Ness big sucker on and with that combo it's like having a new bike. Easy to tune to your seat of the pants feel and hardest thing about it was getting your hands under the tank to unplug the fuel injector connectors. Kit came with O2 eliminators also. It's the same controller as the Arlen Ness Big Shot. I can't say enough about it so far.

 

ive got an 06 dyna street bob with vance and hines slip on straight shots with quiet baffles and k and n filter . anyone else here got feedback on the EJK efi as most people seem happy with them. I really need a bit more performance as most of my friends ride sports bikes and I have it ride it pretty hard to keep up. im almost ready to buy it but just want to make sure.

 

You're wrong, with TTS at least,as you can attach it, go for a nice ride and let auto tune do its thing.
Also you've been reading too many Internet forums for your information. There's a reason the best tuners prefer using TTS.
