estatic Fuel controller testing.

For the sake of the club members I'm doing some more testing. I'll be at the dyno on Monday with a few changes to my build. Originally I ran a dobeck fuel controller and UNI dual stage air filter with EHS lid(with side vents). This was intended to be a safe build for the trails. I wanted a good air filter with lots of protection. Well, I'm switching up to a Velocity air filter which I imagine would flow better than the UNI and I'm adding a Power Commander V. I'll show you real results comparing the dobeck to the PCV on the same dyno with the same tires and on the same machine. I'll post a dyno chart with a side by side comparison of the new set up vs the old. So far the UNI/Dobeck set has worked out great but there are a few rich spots I'd like to smooth out and I will accomplish this with the PCV. Here is a dyno chart comparing Valk680's build with PCV vs my build with dobeck. You'll see some areas where my power curve dips due to a rich a/f mixture. I'll post my findings and a dyno sheet monday. I ordered the velocity filter from Alba and they had excellent customer service. I ordered the PCV from 58cycle.com and their customer service was excellent as well!

your Partial throttle runs will be the most impressive and off idle adjustability

Yea, it was pretty cool to watch them dial in Valk's BB set up. My XX has been running just fine but I want this build to see its full potential. A better flowing air filter and a fine tune should do it. I'll post results in a few days. Dyno appointment is at 10am Monday and I'll bring my laptop so I can post results asap.

I just put the velocity kit on my xx. Ive heard its common for the metal piece in the cone to fall threw and get sucked into the throttle body. So is the dobeck controller the same as the ehs controller?

Yes, dobeck is the ehs fuel controller. I think alba sent me the wrong filter. The box was labeled trx 450 and i do not have an aluminum adapter. The adapter it came with is not fitting right.

No its right. Theyre the same as the 450. Its a plastic adapter and it fits tight
