There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.
Anyone near me knows how to tune?

Get the Power Commander V with auto-tune. You can do the single tune and just install the auto-tune bung to the Y pipe near the OEM oxygen sensor. If you go with the dual auto-tune sensor you'll have to pull the header pipes and install a bung for each cylinder... each one about 8" from the engine.
I did the single version and it works GREAT. You can adjust as needed... make and share custom maps... or let the auto-tune do the work for you.
You can also take it to a place that does Dyno testing and they can dyno it and build a custom map for you... obviously the most accurate way to do it... but some may not know how to dyno a Spyder.
PCV with auto-tune is far superior technology to anything Juice Box sells (power commander makes those units also--- it's their older technology....they keep the newest technology for their own product line)
You can do the PCV with single auto tune for $500. Dual auto tune for $600.

I have this system and it is worth the $$$. So much smoother through the whole power band, better fuel mileage, and more power with my other mods. I am not sure what it would do for a stock or any other setup.

I have the PCV with auto tune. Love it. Its taken about 1000 miles of excepting trims and down loading to build a great map. But I am running a none spyder exoust and with no cat, "RT". I can get 150 miles on a tank of gas running it 13.2% across the board on fuel tables and can bust the tire lose in 2end gear. major improvement in the performance department

Did you weld the bung right beside the stock bung or opposite of it on the Y? Is there enough room on the Y to go right beside it?
Also where did you buy your PCV from?

Plenty of room to weld the new bunghole near the OEM one.
PM sent on where I got mine.. don't wanna plug a business out here......

Thanks for the help firefly. My pcv will be here tomorrow. I got next-day air. I'm going to get the bungs today. I'll ride around all day Friday to let auto-tune do its thing. I guess I need to create a lot of different scenarios when auto-tuning, such as shifting under low revs, shifting under mid revs, and shifting under high revs, and then mix the 3 types up within each other. Sounds endless, LOL. I see why one guy said it took him 1000 miles to get it perfect. :shocked:

Is everyone running their PVC/autotune so rich? What do your plugs look like?
I was running 13.6ish across the open loop part of the map and it was good... but when I went to 14.0 tapering to 14.4 towards the higher end it made a notable difference at the top end.
As far as I know, 14.0 is the recommended target for non-ram air v-twins (meaning pure ambient pressure/vacuum intake as opposed to either ram air or forced induction/turbocharging).
I might wind up taking more than 1000 miles to "get it right" but it "feels good" right now

Good question. Cause I would like to know where to put mine. I was gonna set it at 13.0, but it looks like that may be too rich???

13.0 is gonna be too rich IMO. I went with a stock table for running a 'green filter' and a TB pipe and then just let it adjust from there. I'll have to pull my tables up... but I think the target AFR was generally in the 13.2 to 13.6 range in their stock table. I have not changed those... those are real world targets. The Auto-tune will adjust the trim to try and hit those targets.
Generally speaking you'd rather be too rich than too lean as too lean.... but I'm not sure these can allow you to lean things out to the point of damage... highly doubt you can.
On my AFR gauge I can see it vary quite a bit.. depends on how I'm riding, etc.... but it has settled down more as I apply new auto-tune data... and the AFR readings are FAR more stable compared to how they read when I was running JB with o2 mod.
When I get things dialed in better.. I'll end up with two maps--- one for performance riding and one for long trips. You can hook a simple switch to the PC V that will allow you to simply switch between the two maps... the one in the PC V and the one in the Auto-Tune.

Thanks. Great info. I'll be tuning tomorrow, so I'm looking forward to getting this spyder smoother. One question......do you just leave everything hooked up from ride to ride, never touching anything, and simply just accept the new trims after every ride? I'm assuming you never take the autotune o2 sensor out of the pipe?

No need to take anything out... just plug laptop into PC V...... get new trim data from Autotune and have it apply it to PC V tables. Easy as that. It can adjust trims up to 20% with auto-tune. Just plug in after every few rides and let it do it's thing.
One way to test to make sure the Auto Tune is reading data is to hook up laptop while bike is running.... you should be able to see the live AFR numbers from the autotune sensor.. they'll change as you hit the throttle, etc....
It's necessary to accept the trims first few times to set core structure of map but after that, there is no need. Auto tune will continuously make adjustments as conditions change.
O2 plugin comes pre-set at 13.8 and dynojet set the target afr at 13.2 and said to play with it to find a good balance for ME between mpg and performance. I think I was mostly at 12.4-12.6 at 80-100% throttle and 13 at rest of range except for 20-40% just above 6000 rpm was at 13.8 to save fuel on 80 mph cruising, was told by dynojet not to go leaner than 13.8.
My spyder was dyno-ed at dynojet but auto tune still made a lot of adjustments. I guess it's lab versus real life condition.

on our 2 wheel machines we shared dyno tunes for the commanders to help the guys that couldnt afford it . there was a post were guys listed all there mods and posted there maps .
my question is , does no one on spyderlovers have a dyno tune or is there a reason not to share ? i know some guys are gonna say that no two machines are the same , and dont want to be responsible for someones machine blowing up . but the two brothers and power commander give maps that are on there websites for people to use .
please remember -- ITS JUST A QUESTION . i am here to learn just like the next guy . i just want the best proformance and gas mileage out of the machine.
