Dial-a-dyno!....just plug your phone into your bike via USB and Ring LLOYDZ for a dial your own ....no olives no anchoviesActually, any guesses or info on the "products" to help those who can't get to or don't have a dyno tuner locally? Maybe a Lloydz Autotune? Lloydz AFR gauge?
Instant Dyno Tuner.. just add water? :nerd
No and no.Maybe a Lloydz Autotune?
Lloydz AFR gauge?
I need to find someone in my area that knows Victorys! I just had a local shop put on a Power Commander V on my 2012 Cross Country and I picked it up just now. Has less power than when I brought it in!!! The dyno sheet says it produced 67.48 HP and 79.64 torque!?!?!? Stock they are supposed to put out over 90 hp! Anyone in the Inland Empire area of So Cal???
To my mind a tuner uses an oxygen sensor to adjust a fuel controller to change the output to his oxygen sensor to attain levels he feels is optimum throughout a range of operation. The end result is based on his technical knowledge/abilities and the characteristics of the engine. The dyno is simply a measuring device that displays the result of that work. /QUOTE]
With a speed density system or Alpha-n that is kinda true.
Speed density uses throttle position and rpm to deliver the programed amount of fuel and MAP sensor will adjust based on atmospheric pressure/air density(normally in side of the intake manifold). A temperature sensor will also make corrects to fuel and timing when operating below or above optimal temp.
Alpha-n is a two dimensional fuel map that uses only rpm and throttle position.
When using mass airflow meter, it gets more involved. Now you are rescaling the amount, by weight, of air that is flowing into the engine at each throttle position (measured by volts). You also have to build in a fail safe if the mass air meter goes bad, called load with failed MAF. Injector high and low slope, voltage break point. And this is just the tip of the iceberg with the more complex car/truck tuning.
Sorry, no. Being a tuner most of my adult life and knowing people who are also quite proficient tuners... all of us say the same thing. "If you want to find out how much you DON'T know about tuning, buy a dyno". There is no substitute for being able to SEE what is going on in REAL TIME. There are lots of people, like you, who think a dyno sheet is just bragging rights on a bar stool. Wrong. A dyno is just a way to have a repeatable and consistent measurement, like a yardstick or tape measure. It doesn't matter if it reads 40 HP or 400 HP... it simply allows you to sample what is going on and see what your changes are doing.To that end, an experienced master tuner who is proficient with a specific fuel controller, mechanical or electronic, can tune an engine to the same level. He just can't give you a nice shiny picture for bragging rights.
Do you really think that the only place you benefit from an accurate tune is the drag strip? Dyno tuning encompasses every throttle position and every 250 rpm at that throttle position. It is more about drivability and efficiency than about producing maximum horsepower. Most of the time spent on the dyno, tuning your bike, is NOT spent at full throttle. In fact a small percentage of the tuning time is at full throttle.Sure a dyno might help them see room for minimal improvements but that's drag strip stuff and of little real benefit to most of us on the street.
You have many misconceptions stuck in your head as fact. You don't seem to understand the most basic things about fuel injection.You've pretty much made my point HC. There are millions of internal combustion engines out there running perfectly fine for the situation they were intended without the benefit of it's own personal day on the dyno. I did note that the dyno helps with getting that every extra little bit of performance, the fine tune, but that level of fixation is for a tiny percentage of users. Certainly not a critical consideration for the majority. If the improvements were huge there would be more dynos around with more competent people that know how to use them. There isn't and that was the whole point of Lloydz presentation.
You can list off all the benefits one can find in the glossy advertising brochures about how much better the world will be with a dyno on every corner but as I said, if it made that much difference in a properly ventilated engine, more would be using the service. Commercial vehicles in particular could see fuel and engine life improvements but not substantially so as to be cost effective. The difference between running very well as designed or striving to get that extra little 1 or 2 percent more is for the drag strip and bragging rights. Nobody goes racing to try to come in fourth.
And whose dyno are you going to believe? Your comment "I thought my bike ran great. I was wrong. It runs great NOW" is best for that day and after that only better than it was with it's original shortfalls. The pros on this forum regularly say that there are differences in every situation. Not only the operator but performance figures can vary depending on who set up the dyno and who ran the test and on what day. And it's temporary. The many contributing factors include air temperature, humidity, atmospheric pressure, and a few others you are probably familiar with that I don't even know about. That means even an expert dyno tune is only "perfect" for conditions it was done under. Take a trip to the mountains? Not perfect anymore. Take a trip to the ocean? Not "perfect" anymore. Low pressure weather moving in and rain expected? Not "perfect" anymore. Summer temperatures jump by 40 degrees? Not perfect anymore. Travelling and get varying ethanol levels in the fuel? Not "perfect" anymore. Gas company made the switch to season specific fuel? Really not "perfect" anymore.
To attain your 'Accurate tuning is not about bragging rights or drag racing, it's about making your engine as efficient as it can be and the best tool to obtain that is a dyno.' in my own driving I'd need about three dyno runs a month to maintain that perfect tune.
Sorry, I'm not convinced. I'm pretty confident it would be impossible for me to tell the difference between a tune done by Lloyd using his parts, experience and knowledge without the benefit of the dyno and one he did with the dyno. He'd certainly be able to fine tune some tiny difference at the 20% throttle position but I don't believe many without that piece of paper, if anyone, could tell outside the drag strip.
And yeah, it's still about bragging rights too.
