Better Option, PCV with or without autotune?

[koolcaymancops-S1krr]

Im looking to install a PCV in the next few weeks but not sure if i should spend the extra on the Auto tuner. Can you guys help me out here? What are the benefits of having the auto tuner if you have a map for the exhaust. i like the fact that i can tune the map to get the results I want (more flame )

Tks.

Just my 2 cents worth. I added a PCV to my stock bike with the supplied dynojet cal. I was surprised at the improvement in throttle response in the low to mid RPM range. Depending on where you are, a dyno tune cost 250-300, about the same as an auto tuner. I plan to spend my money on a dyno tune sometime in the future, if the initial dyno run shows the fueling to be significantly off. Not sure there is a wrong answer, as the auto tune should provide good results also. -T1

Closed loop is always better. It takes factors into consideration not present at the time of the dyno tune. It is not possible for the dyno operator to get every cell 100% correct either. That would take him days and by the time all the cells were done, they would be out again due to new conditions prevalent.

Go with the A/T, get a base map and let her tune for you.

What are you guys setting the AF ratio to be for "peak" performance?

Personally I am using the map provided for my full exhaust. I saw a net improvement already in smoothness and torque . And I am good with it. May be I will gain a bit with dynos or AT but for me I am satisfied already and don't think the extra cost will bring me way better

I'm in the same predicament. I'm ordering the AR GP3 pipe and am getting a PCV as well. But what about all these other modules? Auto Tune seems smart since I am at high elevation, but besides plugging it into the PCV what else is involved with installing an AutoTune? Does it utilize a wideband? Is it as easy as replacing one of the stock O2 with the wideband or do I need a bung welded?

I asked Dan K & he said I didn't need it.

I plan on using the map for the Taylormade from dyno jet and go from there. No where to have the bike tuned on a dyno here on Island so thats not an option for me.

My $.02 worth... If you have a "good tuner" near by (not just "a tuner") you're likely to get very similar bumps in HP and in smoothness. Many tuners just tune for 100% pulls, so be aware of what you're wanting and what they are providing. Where the AutoTuner differs and for me personally has helped achieve my goals is in the wider spectrum of performance. If you run the AutoTuner, I highly recommend you run a 6-gear map. I've been able to get the same bump in power, improved acceleration, smoothness, and improved fuel economy using a 6-gear map (one AFR table and one fuel table for each gear). You're not going to get all of that all at once from a custom tune, unless they do a custom 6-gear map and spend quite a bit of time tuning (which could be done, but would take quite a bit of effort and $$). I also live at high elevation (very similar to you Humtek ) and I tend to ride anywhere from 5,000 to 10,000 elevation. So it is my belief that w/the AutoTuner, I'm getting quicker fueling adjustments due to changing conditions... I have no proof of this when compared to stock adjustment capability, but I'm confident it isn't slower, and likely (again, my own opinion) to be quicker (adjustments). The trick is to find the right AFRs for your AFR table(s) that suit your needs. That's where a little knowledge is helpful. If you don't like to mess w/that stuff, a "good tuner" would be more recommended. The other thing I like, is that if I change any other parameters on my bike later on (different exhaust, air filters, etc.) the AutoTuner compensates right away, where as w/out, I may need to get another Tune... and at that time, you've probably paid two times what an AutoTuner costs.

I personally have nothing against dyno tuning and do believe it is a great asset and tool to have. In fact, I've had a custom Tune done for this bike early on. And who doesn't like a good dyno pull to see what kind of number gets spit out

Are the maps for the AutoTuner different then what the exhaust manufacturer provides? Or can I use the exhaust map as a base and let the AutoTuner work from there?

Also, the autotuner uses a wideband, no? Did you get another bung welded into your exhaust?
