Default The difference between AutoTune and professional Dyno Tune

My local shop doesn't have a dyno, so I opted for the AutoTune kit when I had them do my upgrades. After several weeks of adjustments (with a base map from KevinX) I was not happy, and I decided to take it to a professional. As you can see the difference is amazing. I got 12 more ponies to play with and 5 ft/lbs more torque all from a professional tune. Thanks to Brian Livengood at Livengood Motor Sports in Lawrenceville, GA the bike is finally running the way it should.

Nice Numbers and Lines ... Auto Tune is a Fine thing but without a good knowledge of how to accept the Trims to improve it is not going to gain that much .. Pretty Hard to beat a Pro's Tune ..

Very cool!

Now if you had brought it to a Victory specialist he would have noticed that the HP is limited on the top end. The scan is a little fuzzy but it looks like from about 4000-5000rpm the HP goes from a smooth line to a rough line. That generally indicated too little or much timing. Depending on your setup another 2-6 degrees of timing either way would have smoothed that out and gained a few more HP at the top end.

No matter though, you may never notice, and the point is the same, a Power Commander is only as good as the person setting it up! Enjoy!

Good stuff mate.... where I live also NO DYNO... so when i ordered my PC-5 and many more upgrades (see signature ) i requested a MAP to suit my bike..... installed everything and it went from "ok" to worse.. so it was a MAP not suitable for my bike, except if you go to a DYNO? .. anyway a forum member Emailed his MAP with the same kind of upgrades, and hopefully my bike will ride "ok" in the future.....

So I think I will have to purchase a LC200 of PC website. so i can actually see what has to be done in the settings .... Air / fuel ratio's etc.

I started collecting MAPS of all kind of Victory's in Indonesia so I can compare them and hopefully make everything work "perfect"

The strangest thing was on the MAPS that at 2500 RPM the timing was +4 when there is a timing wheel already...... so now I have a good MAP and set the timing wheel on +4 and could even go to +6 or whatever as on this MAP it is all on "0"

The fact that other peoples MAPS don't (always) work well on YOUR bike should not be a surprise to anyone who has read up on this. You often have to go through 4 or 5 to find something viable for an individual bike.

What the heck is a LC200? If you mean a the Power Commander AutoTune, then that is AT-200 and that is the WRONG one for these bikes as it only has a single O2 sensor. You need the AT-300 in order to monitor the Air-to-Fuel Ration on the PC-V

If you are running a timing wheel @ +4 but you want a total of +6 above 2,000, you will need to reduce the timing in the PC-V from +4 to +2 otherwise you will be @ +EIGHT above 2,500 which might explain why the bike runs like crap

i have posted many times about this, if you have a crap map or not sure what you need for af mix you are no better off, just have less money.

i have my wheel at 8 and have timing in most rpm ranges, mine runs good at 8 but in a certain range i do get ping so trying to tune it out.

dyno tune will be best, auto tune is no replacement for a dyno tune.

Odd that you would notice THAT much difference as both tunes are pretty much aligned until (what appears to be 3,500RPM). I DO see the increase above that level and can see the benefit of a professional tuner but unless you are cracking it open, most riders would not notice THAT significant of a difference. Did you just not mess with the upper RPMs on the AutoTune much or do you think that the AutoTune itself simply isn't capable of doing those higher RPMs well?

I ask because I am still learning the AutoTune details in an effort to determine it's true value. We KNOW that using an AutoTune is FAR better than without so for a short time, the AT may be something that could help out a LOT of PC-V (without autotune) in the short term... e.g. better than blindly using maps

Default AFR+ for sure

dobeck's gen IV fuel tuner is so easy, you set the AFR you want + thats it!!! prolly not as "powerful" as a dyno tune done well but very good for me at a lot less $$$$ and headaches. any future upgrades do not need another dyno tune $$$$$
