Anyone heard of how these are working. according to the manufacturer they are the stuff. but they always say that . anyone own and use this?

 

I have over 1000 miles on mine and I love it!! No BS man, it's great.

 

I have one on both of my bikes with several thousand miles on them without any problems.

 

I believe he is asking about the POWRPRO. Cobra screwed up br using the 2000 designator. This one is an auto tuning unit which interfaces with the O2 sensors. They were released this Spring.

 

This is from the Cobra Product page. If the unit does all this - it's impressive.

• New patented technology unlike any other auto tune system on the market
• PowrPro tunes to exactly what air-fuel mixture creates the maximum power 80 times per second (does not tune to a predetermined arbitrary AFR)
• Creates that adjustment to maximum power on every squirt of the injector
• It’s like having the best custom map writing, dyno operator tuning your fuel every time you crank the throttle
• Tunes every gear, every roll on, every environmental change, every engine mod, lugging the engine, winding it out to redline: it reacts, verifies, and adjusts
• Provides perfect fuel settings in any condition, with any exhaust system with any engine modifications
• No external adjustments needed
• No dyno needed
• No additional components needed
• Does not require wide band oxygen sensors

 

Sounds too good to be true. I mean, how does it: "tunes to exactly what air-fuel mixture creates the maximum power 80 times per second" without a dyno to measure the power/torque being produced?

All these autotune gizmos (and, yes, I have a couple on my bikes) are great for hitting a target AFR but they have no way of knowing if that target AFR is actually best for power.

I'm willing to be convinced but have my doubts.

 

how much does this run... i am sick of $500 a pop to dyno!

 

Before you do that I'd suggest finding some independant dyno results. I tried for about an hour last night and I couldn't find a single person who has posted documented proof that this device does as it says.

This device has zero display or interface. You have no idea what it is (or isn't) doing. For all I know its sticking 10% extra fuel in and calling it good.

 

I think it runs around 450 or 500 bucks but if it actually works it would be worth it. Carlisle designs has one and he seems to really like it. A lot of the metric guys have been running them and they seem to like them a lot as well. BTW dyno runs don't mean squat if the bike doesn't have the power where and when you need it. Im going to do more research on this but so far it sounds like a great set up to me.

 

every cobra tuner i have seen, working at bike shops was acting up..i didn't do the tuning, so i might of just not seen the good ones. but never seen another tuner thrown away off a bike
