Tune then flash or Flash then tune?

[Italgeorge]

Just wonder what order I should follow. I have the PC5 with Autotune. Should I get the bike dyno tuned THEN get the ECU flashed? Or flash it THEN get it tuned? Thanks!

[marshdrummer]

Flash first to get rid of the restrictions...

[Italgeorge]

Ok sweet. Should I go with Flash tune or ECUnleashed?

[AKDMA]

The flash-tune interface is the way to go. You can do everything youself and make infinite changes. Def flash, then tune as he said.

yep..and if you are using a dyno to tune, with the interface you technically don't need the PCV.

[AKDMA]

True, but that'd be a painstaking and time consuming way to tune (remove ecu, make adjustments, 5 min flash time, reinstall, repeat). I'd hang onto the PCV for now.

Ok sounds good. Ordering the interface today! I won't need the auto tune anymore correct? Or would it be a good idea to keep it?

You don't need it...what are you doing with it. I ride at many tracks in many different conditions so I like the autotune to use it the 1st couple sessions of the weekend. If you are a street rider, I'd save your money.

[AKDMA]

LOL. "Yeah, ditch it, matter of fact I'll handle that for you". Really, he's right though. If you're getting a custom tune, you shouldn't ever need it again unless you drastically change altitude or something like that.

Thanks for all the input guys. Guess gonna get this ECU flashed, sell this auto tune, and take the bike in to get all tuned up.

Why not keep the autotune and skip the dyno tuning session? Put in 13.0 on the autotune and you should be done.

Bc as I understand it no auto tune is as good as a real dyno tune done by someone who knows what there doing. Unless I have been misinformed?

[marshdrummer]

If your tuner is cool like mine, get the flash, put the PCV on, get the custom tune, take the PCV off, then get it flashed again and import your map...no piggybacks to fail.

The autotune is NOT as good as a custom tune...A custom tune is to get the best a/f ratios/performance out of YOUR bike...every machine is different. Plus, the auto tune is only good up to 6k rpms. Set it up with a custom tune and never look back (unless you go from sea level to Colorado lol). the only reason to keep the auto tune is for gas milage where you are under the 6k (like highway). But I don't think you bought it for the gas mileage.

Now that's a great idea!

Dan Kyle, a good tuner, says the AutoTune will get you very close if you have an idea of what your optimum AFR is. On an autotune, you're able to make changes under real riding conditions including ram air, etc. With the dyno, you're dealing with an expert (hopefully) who will smooth everything out and should be able to make a nice curve for you. Some tuners are better than others, if you have an awesome tuner, the custom tune might be better. But I run an auto tune and have no plans of getting rid of it.

[marshdrummer]

Here's my plan:
Flash to de-restrict, turn off AIS (use plates too), Turn off O2 sensor, use the speedo healer function (-1 in the front), change fan setting.
Put on PCV
Custom tune
Take off PCV
Re-flash importing my custom map
Never look back

why does an autotune only work under 6k?

A dyno tune is better and the only way to figure out optimum AFRs as AKDMA stated...after that autotune is more accurate

Auto tune, from what was explained to me, reads the gas/o2 level in exhaust through the o2 sensor. At the 6k point, the o2 sensor no longer becomes useful and the ECU reads from the map that is on it. I may be wrong, but that is the way it was explained to me.

You are wrong. An autotune read all the way to the engine's limit.
