Considering a Power Commander

[TomN]

Earlier this year I purchased a 2007 VFR and overall, I like the bike however, I am disappointed in the smoothness of the power delivery below 6000 rpm. There are several flat spots where you give it throttle and the bike stumbles, hesitates or does not accelerate, apply more throttle and the bike responds.

I have read quite a few threads about the PCIII and the PCV upgrades VFR owners have installed and most people think it is the solution to the problem. As I understand it, the main difference between the two is the PCV has an additional throttle position (15%), tune by gear and can be used with the Autotune 200 module.

I have the stock exhaust and I don’t plan on changing it anytime soon. I also have the stock air filter, should I change it to a K&N before I install the PC?

There are quite a few comments about which PC can be used with which year VFR and also a lot of discussion about the various maps. If I Purchase a PCV I think it has to be the 2009 model as they do not list a PCV for a 2007 VFR. From the threads, the maps are the same as the PCIII maps with the exception of the 15% throttle position.

Having never had a PCIII/PCV, I assume you change maps via a laptop with a USB cable. How easy is it to change maps?

I do not want to spend hours changing maps and fine tuning the system, I want something that will work well (not race tuned) with the least amount of time. In relation to the Autotune 200, it’s not an issue of money, just time spent tinkering, I don't have the time. I have spent countless hours in the shop tinkering with race bikes and cars and now I want to ride a nice smooth bike without the hassle of fiddling with it. Additionally, I am not Randy Road Racer trying to squeeze every ounce of power from the motor, just smooth and reliable power delivery.

So, I am looking for recommendations should I get a

PCIII, install the cozye map and ride it
PCV, install the cozye modified map and ride it
PCV with AT200, tinker with it and ride it
Other, you tell me

Thanks, Tom

get a pcv and auto tune module. install it and let the auto tune do the tinkering for you...
thats the best advice that i can give you. and im starting to think that this is what i should have done. if you get the pcv and auto tune you wont have to worry about when you modify the bike and when you tune it.

One major addition to the PCV, that model will self correct for alltitude, temperture, and humidity. It also has a bypass mode for higher mileage. Although it sounds like the PCIII will do everything you need without spending the extra scratch. One piece of advice however in regard to the flat spots. I ran several easily downloaded maps and not one of them worked for the 8- 10hp loss ( worse than a flat spot ) between 5800rpm and VTEC engagement. I finally had to cough up $300 to get a custom map. That said Dynojet did not have a specific map for 2bros. so another pipe or OEM may be a differant story. It did immediately stop the surging below 3000rpm regardless of the map I was using. If you goto a K&N do it before installing the power commander. K&N may not do to much for you with a stock exhaust but it will save you some money over the long haul and breath a little better aswell.

Like havcar, I couldn't find a canned map that smoothed power delivery like I wanted. I finally took the bike in for a tune. Issues resolved!
