Re: what

What do you wanna know?
Thx for the response...I know a lot of guys use the PCIII but are having trouble getting maps and such. I was just wondering what's actually better. I know the TFI is analog where as the PCIII is computer based. I just don't know anyone who has a TFI on their 1. Just looking for a bit of knowledge and schooling on it I guess.

well

My point of view is that , you want either one to make your bike run as good as you can, yeah? So the PC allows you to (on a dyno) see what YOUR bike is doing (they are ALL different, same bike, same mods, different map) and change it at 250rpm increments, at anywhere between 2, 5, 10, 20, 40 60 80 and 100% throttle. Using tuning link on a dynojet dyno, your bike is also placed under "real world" conditions and mapped under them, making it the best way to go (in my opinion) for the mapping of your bike. To spend the money on the equipment to map it, and then muck around with "different" maps, to me is pointless and a waste of time and money. If you're gonna do it, do it properly. Hope this helps.

Oh, TFI? Man there are hundreds of things available to do this sort of thing with, but I think that the PC's are the most accurate, best value for money method of doing it. But what's TFI?

There are several companies that make them Techlusion is the one I'm most hearing about. http://www.totalfuel.net/
This is a site my buddy sent me too. I guess it's just a different type of fuel manager. By the way, thx much for the education.

Okayyyyyyyy

"The TFI box (that stands for Techlusion Fuel Injection) is made by the guy that founded DYNOJET. Besides the obvious, the price, the TFI works really well on your real world road bikes, whereas Power Commanders were designed for race bikes which could be used on road bikes, this TFI box is designed for road bikes. This means that you are going to get a much more defined and accurate set up for real world riding. And with a working accelerator pump circuit, reacts like a finely tuned carburator."

from the site is VERY old and outdated. Most of what I read there is total B.S, when related to the PCIII and PCIII USB that you'd use on your bike. You have NOWHERE near the control on that, that you do with the PC, and it sits exactly where the PC USB sits, between the ecu and the injectors, Only the old PCII's were put before the ecu.

"Techlusion TFI Installation:

The TFI box is an easy installation and can be set up in your garage without the need for a laptop computer (which the Power Commanders really need)"

You don't NEED a lap top with the PC and Yeah you WANT to use a computer of some sort coz you NEED to be able to "measure" what your bike is doing. That site makes me laugh. If you wanna waste your $'s, get that. Trust me, The PC is WAY better.

Sweet thx a bunch. Another save of wasted money.

Oh man

"Technical Breakdown:

Sensor Manipulation Boxes basically lie to your bike’s computer about engine sensor values in a way that influences it to change fuel delivery in a pre-planned way. Unfortunately, this expensive scheme breaks down when your engine encounters temperature and altitude conditions that require the enrichment you were depending on to enhance performance and ridability. Also for diagnostic work that needs to be done using the Scanalyzer, the Power Commander needs to be disconnected."





Thanks for this arrigo, this is one funny site. They have NO IDEA what they're talking about. NONE. BUT they say that this is the ONLY thing they've tested that removes fuel, in which case again, that TFI unit is a complete toss. Forget it. But thanks again, those guys are f'kin hilarious.

It never ends

"Dynojet PC III Cons:

The power commander actually gets in between the sensors and the ecm. The power commander requires the user to input different values to ecm so it can create a different map than normal. This is all done on a fourth gear roll on with a dyno in conjunction with thier software and they achieve good results, in fourth gear. Power commander technology is rpm based. Techlusion technology is load based. My question to you is: Do you think that your bike requires the same amount of fuel in fourth as it does in second? "

Man where do they GET this shit? It's A1 comedy. Kinison, Dice, Rock, they got nuthin on these guys. VERY funny an they have NO IDEA.

Yep

I am, I'm only a Tuning Centre that has mapped bikes for Ducati Australia, most bike mags in Oz and an R6 in Oz supersport that is beating the all the factory bikes bar one 600RR and does this for a living. YOU are a guy with an R1 and a set of mufflers they like without the brains to get the bike tuned for them so it runs at its best. I know NOTHING, and I SHOULD be listening to you obviously. So sorry. :finger
 
#14 ·
Yep

So why are you? Coz you obviously know nothing yet still spout. That's why I come to places like this, to cut down on the amount of stupid questions I get from guys that "read it on the net". Sorry, I don't mean to be such a prik, but yeah........ I DO know what I'm talking about.

Fight nice children or you're both going to your rooms!! lmao
sook thx again for the knowledge. Glad i was able to give you a humor site to visit once in a while...don't use too much though it might lose it's appeal

Um

I never said that the unit was a bad thing, I said that the guy writing about them is full of shit. He knows SFA about what he is writing about just like you do, saying that all you need is the pipes you have and that's it for the street. If you wanna be technical, you don't need those pipes at all, do you? Your bike's fueling with those pipe is all over the place, and while they have you h.p etc, it'd be a WAY better bike to ride, use less fuel etc etc if it was mapped right. You'll never know, coz you know best.

He's not my competition, I am not Dynojet and I'm on the other side of the world. I'm just calling a spade a spade, and I bet if someone in your field of work was on the net posting absolute laughable bullshit, you'd be takin the piss too. Like I said, nothing WRONG with the unit, besides from the look of it, it only adds fuel which is useless. Haha. He spends half that site bagging HIS (powercommander) competition also, but whatever, like I said, you now best.

Yeah you know more than yamaha ever will!

I'm not a tuner or anything but I think that the cons with the fuel nanny or the cobra box is that it can only richen the mixture. In looking at alot of the mappings on the r1's the mixture actually needs leaning out throughout a lot of the rev range. I know people who have put pc3 usb's on stock bikes and have really enjoyed the outcome. It will smooth out the thottle transitions and you can smooth out the idle that starts to move around once slip ons are added to the bike.

Just my .02 but last night I installed my PCIII USB. The new throttle responce as well as lop it to out of a couple RPM ranges makes it totally worth the money. SHIT i'd pay 500.00 bucks for one. I think they are under priced with how much it improved my bikes performance.

Hahaha

Keep talkin mate, you're only proving yourself to be dumber than I first thought.

And YES, Raven and bigpun, it's a waste of time, only being able to ADD fuel, as 60-80% of most maps will be rich to begin with.The point is, you don't have to be a "tuner" to understand all this to some extent, yet Sharknose still finds it difficult. Funny stuff.

Eagerly awaiting your next "masterpiece"

Sook you're killing me!!! LMAO Thx very much everyone for your inputs...I ordered my PCIII yesterday and most mods should be in place by wed next week.

Yep

OK, Hands up, guys........................how many of you have put on a PC and had it mapped, only to have your bike cough and splutter and run like crap compared to the "Yamaha knows best" mapping? Huh? Come on, let's hear from you all. Hahahaha You have absolutely Nothin' SN.

I have something to say Sook!!! Thx man!!! I just got my bike done today w/the PCIII and she runs like a bitch in heat!!! almost 11hp through the 6k - 8k range and 5.2 hp overall. Money well spent. Thx for the input.:bow
