Custom Dyno Tune w/ Autotune

I have my bike booked in this coming Wednesday for a custom Dyno tune. The guy that I am going to does turbo bikes and came highly recommended.

When I spoke to him on the phone he told me he will have to remove the Autotune? Is this correct?

I installed a Map switch on my PCV. So I thought I could switch it to the OFF position, and he can do a tune for me. Then once its done I can leave it in the OFF position and run off the base map he created, or move it to the ON position and the Autotune will make adjustments, then at any time move it back to the OFF position and it will revert back to the basemap without using the Trim adjustments the Auto tune did?

Also another question. Why is a Dyno tune better than an Autotune?

With the Autotune, it is making trim adjustments based on 100 mile an hour RAM air going into the airbox. When you get a dyno tune the AFR is getting adjusted based on air being blown by a big pedestal fan?

If you have an Auto Tuner, why are you going to see a Dyno Tuner? You spent the money already, and should easily be able to make a map equal or better than a tuner, because of the ram air at speed on the bike.

A tuner can get you in a better range and will understand a lot of the information better than you will in terms of getting the most potential, like adjusting air-fuel ratios, but still, you can do this with a little research, and know whether you should be running 12.9, 13.0, 13.1, 13.2, etc...

I wouldn't see why you would want a tuner to build you a map when you can build it yourself?

Because I am dumb as dog shit. I don't understand it. The bike isn't running the greatest, and I have no idea how to fix it.
The map I downloaded from the power commander website is useless apparently. The USA has different fuel to what we run over here. I run 98 octane- no ethanol.

I dont understand the AFR values. And where everything should be. I had a shitty dealer do my ECUnleashed, I am not sure if it got rid of the closed loop. I am not sure if I can remove the little black o2 optimizer. I'm just lost. I drive trains for a living. I am no mechanic.

Like I am trying my hardest to understand. But it just isn't sinking in for some reason.

Regardless of where you start, zero map, downloaded map, or dyno tune the end result will be the same with the auto tuner (if you put in the same settings). So why pay for the dyno tune. I would take the auto tuner off and toss it if you're gonna do the dyno tune route. Or just read up for the next few days and stick with the auto tuner.

The benefits of a dyno tune over the auto tuner are for diagnosing issues, finding max power for your bike, make the power delivery smooth. Most street riders don't need those "perfect" though so the auto tuner is great. But it's only as good as the settings you put into it of course.

Basically I do not know where to start.
I downloaded the map for my bike mods from the powercommander website. but the 6000rpm-15% throttle target AFR table is all zeros. I have my ECUnleashed so I should be able to adjust this range but I am not sure what targets to put in these squares?

I put in 13.2. The bike seems to be running fairly good. I do get the occassional back fire on decel.

I need to learn HOW i should be altering the AFR target table so I can let the Autotune do its thing. Every square is 13.2 except once you get to the higher RPMS and it changes to 13.1 and 13 with the occasional 13.4.

I can't really seem to find any tutorials on it.
Also because I am running 98 RON fuel, and not ethanol based fuels like in the USA, I am assuming these figures would be off?

Just save your money and do not do the dyno tune. I have a auto tune on mine and my friend owns a dyno. Just for sh!ts and giggles we put my bike on the dyno. The before and after his tuning numbers were almost identical to what the auto tune did. I trust the auto tune to make on the fly adjustments far more than I trust a base map that cannot change.
