Depends on the pipes. Try it and see. If not as good switch back to stock until you have the bucks .

Cobra PowrPro is your best bet and, believe it or not, cheapest in the long run .

 

[Señor Gar]

Why cheapest in the long run? What's wrong with the regular Fi2000?

The PowrPro is a game changer, plain and simple. If you read the link in the previous post you should understand. If you need more convincing do some PowrPro searching on this and the M109 forums. Everybody is getter better mileage, smoother running and more power than they did from the other fuel controllers. Just one dyno-tune will make up the difference in price. 'Seat of the pants' controller settings are hit and miss for most. Like they say, 'You can pay me now or pay me later' .

 

[Señor Gar]

I have to rely on the recommendation of Honda and they say the Power Commander 5 from DynoJet is self adjusting and the best on the market that's why I bought it . Don't you have to set different maps on the Cobra, like 1221 or something like that ?

The PCV with AutoTune is self adjusting to the user calibrated map. Bad map = bad ride.
PowrPro is plug & play and is truly self adjusting with no user interaction. Probably wasn't on the market at the time of your recommendation from "Honda" although I doubt whether Honda, the manufacturer, would ever recommend such a modification.

I've been on this forum almost 3 years now and we've been down this road before but if you newer folks feel the need to reinvent the wheel, well go ahead and knock yourselves out .

One thing is clear, you haven't done your homework. All the smarts and theory will not replace the experience of those that have gone before you.

I agree, but I also read once that if we ignored all the post from duplicated topics, we would become more of a silent library more than a community family and the forum would probably die.

Grapnel, you misread me; these old arguments have long since been laid bare, yet I agree, duplication is essential to get everyone up to speed and so is doing the previously suggested homework .

Homework done here!

No disrespect intended but I'd say the only one on this thread who has done his homework is X_KIOWA_X .

Homework starts here:

1. Search this forum for threads on "PowrPro": QbanFury, Jag30, joefury have 'em .
2. m109riders.com
3. More M109
4. A very well written review on an '06 Ultra TC88.

There is a lot of material here so take some time to discover what others have learned by trying the products in question before you spend hundreds of dollars and risk disappointment .

Unless a fuel computer is interfaced with real time data with The stock ECM it has no way to alter the fuel table. The cobra just connects to the injectors how does it read the ECM data to make a change at the injector?

Stock ECM makes the readings, including crankshaft speed, and times the injection pulses accordingly. The very small time variance between injection pulses is read by the PowrPro as rate of acceleration to determine the effectiveness of it's pulse width adjustments and it is all done at 80 times per second . Instead of working to a user set fixed map, the PowrPro is continually making slight adjustments to each power stroke, rich and lean, to achieve the highest rate of acceleration between power strokes and in essence "dyno tuning" under actual riding conditions. No other MC fuel controller does this.

 

[Señor Gar]

Still aint drinking the cool-aid, so you are saying the cobra is a majic box.. with its own brain and modulates pulse width with no external input from anything other than the injector?

Actually that's what Cobra is saying. No magic, just contemporary electronics.

If you think about it the sequential injector signal gives you RPM, Acceleration (time variation between pulse ON), Mixture (pulse width). All the PowrPro does is vary the pulse width longer and shorter to get the best acceleration. It's so bloody simple a fifth grader would ask why hasn't it been done before. The answer is it took time to develop an affordable high speed processor that could do just that .

 

[Señor Gar]

As I have stated before the stock Fury fuel curve is pretty damn good, even with a set of pipes the AFR is NOT out in left field so you could get away with not doing anything else in most cases. I will put any fuel controller out there up against the new PCV and will guarantee we can make more power, no hype here, just fact. Alot of power is left on the table without adjusting the timing, I have posted graphs on this forum already if you would like to search. And if the speed limiter is an issue, there is nothing else out there that I am aware of.

This is the difference between riding and racing. The power gain is above 4300 RPM. If you want bang for your buck you need to see improvement below 4300 RPM where at least 90% of your riding is done .

Has anyone else seen one of these other controllers actually function on a dyno? My guess is NO. Because the ones we have tested simply don't work.

Sorry, but there are dozens of very satisfied users of the PowrPro reporting on various forums who strongly disagree with you .

The AFR is extremely inconsistent. How does it work in steady state throttle? How does it know if you are going up or down a hill or have moved the throttle? it doesn't and therefore gets very lost.

I trust you believe what you have written here but my formal FI training and professional experience says it just ain't so .

I know I am biased but just don't believe everything you read, including what I just posted. Do your homework and hopefully you will choose the best unit that fits your needs.

A very fair statement indeed .

Guy française, bien qu'il y ait une certaine spéculation de ma part participé aussi, je suis d'accord avec votre analyse dans les deux messages, y compris l'AutoTune ne pas être en mesure de corriger les autres variables parce qu'il suit toujours la carte. Le problème que je vois, c'est que la carte est créée sur un dyno et non les conditions réelles de conduite.

La nouvelle PowrPro élimine également les corrections pour O2 stoechiométrique sur la croisière, mais il fait le meilleur ratio air-carburant dans toutes les situations. Même sur "croisière constante" Je pense qu'il ya assez de variation minute en position de l'accélérateur et l'accélération pour obtenir une correction mélange. Maintenant, je suis spéculer: depuis le meilleur mélange est stocké en moyenne il peut être utilisé pour la croisière, si la variation de croisière constante est trop faible, car il ya encore un changement d'accélération juste avant le moteur atteint un état de constante.

En ce qui concerne les capteurs d'O2 qui sont à bande étroite, ne vous retirez-les et remplacez-le par un capteur à large bande et deux résistances éliminateur?

 

[Señor Gar]

Thank you for french text !

Ma compréhension de AutoTune est un peu différente et se base sur des informations reçu des appels téléphoniques à DynoJet. On me dit que le PCV et AutoTune utiliser des cartes ». La carte PCV pour le est ajusté à votre moteur en utilisant le dynamomètre et est conçu pour accueillir toutes les modifications que vous avez faites à ce moment-là. Comme vous le dites, la syntonisation automatique est chargé avec une carte différente, qui est une table fixe de l'air-carburant, mais il n'a pas besoin de s'inquiéter au sujet des modifications que vous avez faites ou feront à l'avenir, car il peut s'adapter à vos paramètres de la carte privilégiées (ratios du combustible air) basé sur les commentaires des singals de la sonde O2. Dans les deux cas, votre performance est limitée par la précision de vos paramètres de la carte de base. Vous devez faire confiance que vous avez une bonne carte et très peu de gens sont capables de créer cette carte. Je pense que vous ne pouvez pas faire une carte parfaite car il ya trop de varriables entre les conditions de conduite équestre et styles et la plupart des gens vont faire une carte mauvaise.
Le PowrPro mesure les variations de l'accélération de la rotation du vilebrequin. Trop ou trop peu de carburant permettra de réduire l'accélération.La bonne quantité de carburant vous donnera une meilleure accélération dans toutes les situations. Il est très simple. La question est de savoir si cela fonctionne vraiment et si elle gaspille le carburant. Tout le monde qui l'a essayé, dit qu'ils ont plus de pouvoir, le bon fonctionnement et le kilométrage aussi bon, mais le kilométrage généralement mieux. Ce n'est normalement pas le cas avec les contrôleurs d'autres carburants. Normalement, si vous avez plus de pouvoir que vous utilisez plus de carburant. Le contrôleur de carburant améliore à la fois, donc logiquement nous devons penser qu'il fournit le meilleur mélange de carburant dans toutes les conditions.
Le "AutoTune" est OK dans la plupart des situations, si correctement définies, mais il est difficile à faire. Le PowerPro est correcte avec aucune entrée d'utilisateur et n'a pas besoin pistes dyno ou des capteurs d'oxygène. Il en coûte également moins d'argent et est beaucoup plus facile à installer.
Avant PowrPro Je pense que le AutoTune était le meilleur disponible, mais il est maintenant l'ancienne technologie. Il ya toujours quelque chose de nouveau et mieux à l'horizon.

 

[Señor Gar]

What you do is so sure that the Cobra PowerPro provides the corrected amount of fuel, how does the cobra also know what mods you have made the bike until the exhaust inlet and air? I know you need faster and more fuel is supplied by the same stock ECU, with a table of fuel that is user adjustable as dynojet that you can work the card to suit you're riding model and mods. If the Cobra PowerPro was doing his job I would think also that the fuel mileage go down not up. The PowerPro can also stop jumping deceleration?

First things first dewking, remedial English classes aren't all that expensive .

On your other points I do not mean to be disrespectful as you have been in a few of your earlier posts but you would need to take classes in fuel injection theory if you are still unable and wanting to understand the explanations I have offered so far.

Most folks really don't care about the why or the how, they just want to know if the PowrPro works. I have read dozens of end user reports and every last one is very satisfied with the improvement and the bang for the buck. Those who have upgraded from other controllers are surprised that there was that much room for improvement left on the table.

I am not knocking the PCV+AutoTune, it was one of the best until the PowrPro came along and raised the bar. I can understand your skepticism considering your present investment in the DynoJet product but 100% satisfaction of the new adopters of the PowrPro is all the reassurance I need.

 

[Señor Gar]

Sorry Gar no disrespect intended, I am in the market for a controller and gathering my own information as to what unit I want to buy, your comments have been very helpful to me, sorry if I came across as being disrespectful.

Thank you Dewking . All is well in Furyland again

Hi,
You are right but you are making a little mystake.
I know it's confuse and difficult to understand until you have one.
It's not easy to explain for me. I will try..

Thank you for such a thorough explanation . I am not sure where my mistake is and I do agree with everything you say but you explain it better.
Using Google Translate I translated to french to english and back to french many times before sending because I hoped to reduce loss of meaning but still there is some confusion .

With your excellent knowledge of how the PCV + AutoTune works I think you will have a very good result. Unfortunately most riders cannot achieve that and in my case, even though I understand, it is far too much work to get the best result and, even then, I am sure I will make some mistakes in the values I choose.
