I believe he refering to the stock air box . Sweet Tooth as I just posted on another thread . I think you need to take you bike to a dealer or a independent shop. Have them find and correct you over rich conditition and clutch problem. After all that corrected. Then you can think about a fuel controler and air box mod. To start changing things just because every one has them. When you still have unsolved problems. Will just add I think to find and fixing the present trouble.
I'm running the FuelPak but I'm real intrigued with the PC AutoTune. I'd like more info on it --- is it a true auto-tune (like the factory ECU)?

I'd like more info on it --- is it a true auto-tune (like the factory ECU)?The Ecu for the raider is an unprogrammable open loop system. Open loop because it can make adjustments via the sensors. But it is very limited.The PCV can work in two ways. As a closed loop system where it runs your map without adjustment (the stock ECU will still make some minor tweeks for altitude if I'm correct). The nice thing with the raider is that the motor doesn't have issues when traveling from sea level to a mountain climate...so a closed loop system can will still work well.If you add the Autotune, the Autotune will act as a true open loop system, the PCV runs the map, the autotune correcting the map itself as you go (sampling at 80 times per second). With the autotune your getting everything but air reversion (especially with short pipes) can have an effect on the o2 sensor readings causing the map adjustments to be off in certain cells. My preference is to only use the autotune to create your map than disable it and run the PCV alone and a static map slightly tweeked by your stock ECU for altitude (even though this tweek isn't necessary).

If it's better to run the Autotune in a closed loop system, why would I want to purchase it? Is it that much better than the FuelPak (which I'm actually quite pleased with) and if so, how? The only issue I have is I do a lot of elevation-change riding and I disagree with not much difference...I've always had a very noticeable dropoff in torque at altitude.
That was a really big nutshell. I'm guessing you missed my remark of being very pleased with the FuelPak -- I don't have any issues at all with the FuelPak and have no idea what disasters your're referring to. I was asking about the Autotune as I'm always looking for a little extra seat thump...but not if the cost doesn't justify it. I think I'll stay with my "disaster" for now until something that I know is better comes along.
I think right now the cobra auto tune is new and like anything new has few flaws some people get the flawed one . And some dont. Seems like Capt_Zoom knows what hes talkin about on the short pipes. I hate tryin to jet a bike with short pipes. Agrivatein to get them in the (sweet spot). On the PC Auto tune. Do you have to take that one to a shop to get it done ? Or can u tune it your self the first time ?

Making a map is easy...just install, ride 400 miles, and accept. But that map might suffer from problems due to air reversion. So I came up with a procedure for making a better map. Its a bit more involved but with patience most people can do it.If you don't get the autotune...just try one of the maps we made and posted here. Try it..if you like it roll with it. If not get the autotune and make your own or bring it to a tuner shop.Tip....if you make your own map, using one of the maps we provided might be better than what dynojet does since we can match your setup. Dynojet and fuelmoto are using a generic map without BAK.
The Fuelpak for the Raider is map based.
