If you plan on future changes that would require a tune then auto tune pays for itself quick. If you plan on setting it up and leaving it alone, a trip to the dyno is the way to go. Its all about the versatility you get from auto tune. Parts changes and different fuels ect

Please understand that with a constant running auto tune you are basically assuming that the cheap Bosch sensors that come in all the "auto tune" kits is going to continually read accurately.

To prove the inaccuracy of the auto tune sensors, we attached 2 different Bazzaz Auto Tune sensors and 2 different Power Commander Auto tune sensors (which by the way we're all just Bosch 4.0-4.9 sensors), and then compared the readings to our laboratory grade NTK sensor we use for tuning.

The auto tune sensors all read lean compared to the NTK, and I definitely trust the $400 lab grade sensor over some $40 Bosch sensors.


I guess what I'm trying to say is.... Put it on the dyno with a quality A/F reader and don't look back. A lot of tuners, us included, don't charge a full tuning session cost if you come back every once in a while with a minor change.

Yes, that is the technical term for the higher end NTK sensor.

Yes there is a difference between a good 02 reader but for a bike with bolt ons that is not a built motor or boosted, is that really the best way to spend your cash. I would hope on your dyno tune you would use a quality sensor but for the average joe with a powercommander?

Maybe my post reads wrong, I'd have to reread it to see lol.

I'm saying that you should not auto tune unless you plan on going through several different environmental conditions within a small period of time.

All of our tunes, either built turbo or built motors, or the "average joe" with just a power commander, get tuned with the highest quality NTK sensor you can buy. That way it is dead on. I have had bikes come to me that are "tuned" with uncalibrated or incorrect O2 sensors, and they're wondering why the bike isn't "quite right". Any quality dyno operator/owner should do the same, use the best equipment possible for the best outcome.

I'm not saying anyone should drive around with a basic bike and a super expensive wideband (power commander and Bazzaz actually are calibrated to the Bosch so you couldn't anyways ), I'm saying trust the dyno tune one single time when tuned with a quality AFR unit, and leave it be.

Now, if your only option is to go somewhere to dyno tune that uses a sub par AFR analyzer, then definitely save the money on the tune and let it auto tune for you lol.
