Default From Cobra Fi2000 PowrPro to Lloydz VFC4

I've switched from Cobra Fi2000 PowrPro to Lloydz VFC4. Here are my initial thoughts.

Cobra Fi2000 PowrPro Pros: Set it and forget it. I didn't have to worry about maps, settings, reading numbers, reseraching, etc. Installed and rode worry free.
Cobra Fi2000 PowrPro Cons: Being harassed on the forum because the unit was designed by the wrong Dobeck brother, or what was claimed on the spec sheet and what was actually achieved, etc.

Lloydz VFC4 Pros: It's so easy, my dog could start tuning (nothing derogatory towards my dog, he actually happens to be a very smart pooch).
Lloydz VFC4 Cons: I find myself staring at the gauge while riding! Not a good thing. Also, I see it in red-blue flashing under hard throttle - I thought I was supposed to see solid Red. Does anybody know?

What I liked about Cobra Fi2000 PowrPro is what I like about VFC4 as well: both of them adjust on the road, where all factors are being considered (temperature, wind load, grade of the road, weight of rider, etc.)

Please add your bike's year and model to your signature. Here's why.

Sounds like it might be an improvement over the VFC-III, so I went onto Lloydz web site and it isn't there. Do you have a link to it you can supply?

My wife dragged me away over the weekend but I was able to finally get my Cobra Fi2000 installed Monday morning before work. While I had the tank off I removed the air-dam.
I managed to get a 20mile ride in and I'm happy with the tuner, no it didn't turn the bike into a rocket ship, but its got better power and response, especially in the lower rpm ranges. I tried hard but could not get a backfire or decel pop out of it. I defiantly like the idea that I don't have to worry about tuning for future upgrades.

You didn't mention whether or not your arms are torn out of their sockets now.

I added a little cheapie fuel controller recently. I've had to back it down to almost nothing. It runs fine 99.9% of the time, but for some reason, every so often the bike nearly dies when I accelerate from a stop. The bike never did that before I added the controller.

I can't put my finger on anything I'm doing different from one stop to the next, and the intermittence of the problem is annoying. But since I've dialed it back, it has quit its stumbling.

So... I think the question on everybody's mind is why a man who has a fuel controller this perfect, would switch to something else?

You were the victim of harassment? Really?
People pointed out that it didn't do what the brochure claimed it would do. No more, no less. The only victims were those who fell prey to that bullshit brochure. Cobra victimized you, not any forum members. You didn't like the message, so you blame the messenger.

If the Cobra actually did any of that you wouldn't be replacing it.

Please explain how a unit that only reads crank rotation manages to get information on rider weight, grade, weather, and wind conditions? Buddy, that's one hell of an algorithm! At least the VFC-4/AFR+ is reading an O2 sensor for information.

Solid yellow blue (Y/B) is what you should see when you are in closed loop cruising mode. solid R/B is what you will see when you are in acceleration closed loop. closed loop is when the controller maintains the settings you made in yellow alone or red alone.

If you want to read about this controller go to http://afrplus.com/

You're sure its a VFC-4 and not a VCF-3?

You have to call Lloydz to get one. They're not on his website yet.

So far I'm learning how to use this thing, so nothing has been torn yet.

I never said I had the perfect one, because I don't think a perfect one exists.

I see your point, but I am intrigued by the ability to change the A/F ratio between peak power and peak fuel economy to match the kind of trip I'm on.

Yeah, that naughty OČ sensor was the toughest part of the whole install. Apparently they're tightened by the Incredible Hulk.

I see green on deceleration or idle, when throttle's closed. The rest of the time, from mild acceleration to wot I get solid red and blue. I'm still confused why I don't see yellow at all. I thought I would see that when just coasting with minimal throttle.

Your red/blue is set to low.....http://afrplus.com/AFRplus-tuning.asp

I have had one for about 2 weeks now. Sounds like you have not got the switch points quite where your bikes needs them. Y/B should be adjusted to get into closed loop (yellow blue) as early as possible. On my bike this is around 11. then set your R/B to only come on when you get into the throttle ( on mine i think it is about 14). You will see a grean light on coast or decel. and flashing blue when the injectors shut down when the throttle is closed. Normal progression you should see green, yellow, yellow/blue/, red/blue.

I think it is a little confusing, but the only modes that you adjust an A/F ratio on are the yellow and red modes. The other modes are how much fuel is added or subtracted and use the numbers on the gauge as reference only. For example my green mode is set to about 11.5-12- but I am getting 13.2-13.5 at idle.

So far I am very happy with the unit. It works as advertised, and has improved the performance of my bike quite a bit.

I was waiting for loydz to get them, but got tired of the "It will be ready soon" replies I was getting from them. Finally went straight to Dobeck for mine. Not sure how the loydz branded unit could be better, since you are basically building your own map based on your riding style. For me this is head and shoulders above a vcf3. Having the feed back from the gauge is fantastic.
