I have a honda cbr 600f 01 with a Sarachu sportive exhaust. The engine is not working very well in low RPM's and I heard that a power commander can solve the problem. It started right after I changed the original exhaust to the sportive one. Is really necessary to use this device in my motocycle? Is there any other way to solve the problem? Since it is not a original equipment, can cause some damage to my bike?

 

First, what do you mean by "not working very well"? Sluggish, slow throttle response, backfiring?
Second, is that a full system or a half system. Half especially, changing the exhaust should not a cause the bike to run poorly. I would doubt a full system would either. I would look at things such as spark plugs.

 

Actually if you have a different full exhaust, it can mess up the bikes performance. A power commander would solve the problem

 

I did a lot of research on aftermarket pipes without power commanders and this is the best article I have read.

Although a Micron matched Power Commander (PC) with the Micron products is not required, there is as much, if not more, performance to be gained from the fuel side as compared to the product itself. Also consider that your bike is VERY lean to meet US EPA emission standards (which it is!), and any GOOD performance product will flow more air (which they should), so without additional fuel you are getting much too lean. The stock fuel maps are required to stay within the laws of the EPA, which means they are not allowed to compensate in any way which would exceed the emission standards, thus you have a lean curve, that basically stays lean.

Best of all, we have mapped the Micron PC specifically to our product, to maximize the overall performance of your machine, thus saving you the time, effort and cost of trying to program a 4 dimensional computer controlled map all by yourself. This makes the Micron system the easiest way to get the performance you want, with the least amount of hassle or down time to your machine.

Do you HAVE to do the Micron PC? No, you do not have to do anything in life, and many companies are more interested in selling you their product rather then telling you the honest answer. But you are probably aware enough to understand basic "engine 101" which tells you that if you change something at one end, you are going to need to change something at the other end. In this case, any aftermarket exhaust product which flows more air, is going to make your very lean stock motorcycle VERY, VERY lean, so you make your own choice. If a company says you do not have to re-calibrate with their products, then either they are no better, or worse, then stock, or they don't care what happens to your motor...

So, for optimal performance, throttle response and engine durability, a Micron PC is a highly recommended part of the overall performance package.

Hope this helps, let us know if we can be of any further assistance.

 

Thanks for your quick reply.

I just changed the can. It's seems that the engine runs poorly at low RPM's. It's failing like a two-stroke engine, with a non-uniform working. After +- 3500 RPM, it runs smoothly, more uniformly. Since it is a fuel-injected engine, it's not possible to regulate the mixture, like a carbureted one. I hope a powercommander can fix the problem.

Thanks
