So long as you don't change the exhaust, air filter, fuel combination it will stay right. There will be a significant cost for that service but at least you will know it's done right. take the bike to a dyno tune expert to build the correct fuel map to suit. Finding the right map could prove problematic as there just aren't that many around. Then just load the map into the PCV and you're away. search the internet (commence with the Dynojet web site) to find a proven fuel map to suit your exhaust, air filter combination. You could fit the PCV and the muffler very easily yourself and then:ġ. (05-01-2018 07:33 PM)Retsel Wrote: The first question is, what bike do you have? Second, what are you looking to achieve?Īha, you already have the PCV and got it at no cost, very cool. You just need to decide what is important to you. Is you are looking to increase power or noise level there are lots of options. I did get some improvements in throttle response but my main goal was to eliminate the limiters.Īs far as actual performance improvement, I got the most bang-for-the-buck by adding two teeth to the rear sproket of my 2014 standard.

I chose to keep the stock headers and add a slip-on, Staintune. If you want to eliminate the limiters you will need to have your existing ecu remapped as well. Okay, I see from a previous post that you have a 2014, I assume standard? If you are looking to eliminate the catalitic converter, with a new exhaust, I would definitely go with a powercomander and either use one of the existing maps available, for your chosen exhaust, or have it dyno tuned to optimize for your setup.

That way I can simply remove the power commander and have it running stock as far as the fuel mix goes.īut there are some in the forum that only had the fuel map changed in the ecu flash and are happy with it.Īre you planning on any mods to the intake or exhaust? I did end up flashing the ecu as well but only to have the speed limiter removes and the rpm limit raised 500 rpm. I have a power commander with both intake and exhaust mods. Eliminates that jerky response when first rolling the throttle on. Gas mileage can go down depending on how you ride but once you feel how much smoother the throttle is especially when first getting on it you likely won’t mind any gas mileage difference. Re-mapping the fuel gets more gas in the engine that the engine is capable of burning. The bike is setup lean from the factory to help meet emissions in the u.s. Of course if you want the speed limiter remover you will need to have the ecu flashed regardless of a power commander. If you aren’t planning on making mods to the exhaust or air intake then either finding a map online to load into the power commander or getting the ecu flashed with a fuel map for stock exhaust would also work and may be cheaper than the Power commander and dyno. If you are planning on changing your exhaust, headers, or air intake do that before the dyno. If you are primarily interested in better throttle response and power and are willing to spend for a power commander I would skip the ecu and spend the money to get it tuned in a dyno.

They can also typically remove the speed limiter and raise the rev limit a few hundred rpm as well. Again that works best if the map they use was based on the same configuration of your bike. Some of the ecu flashers will do a couple of things one of which is to flash a new fuel map into the ecu. That method can get you better than stock results but only if you have a similar bike setup. They will include the bike setup of things that affect the air/fuel mix like the type of exhaust and any mods to the air inlet. Some people will bypass the dyno and use maps others have had made and posted online. If you want to remap your air/fuel accurately then a power commander and fuel map generated on a dyno will give you the best performance. Well you don’t necessarily need to do both.
