Hey guys I tried a search but couldn't find the info I need.. My bike is at the dealership right now getting my new Akra carbon and PCV installed and I just looked on Power Commander web site to see what maps there are and it only says Akrapovic full exhuast. I concerned that map is most likely aimed at the Ti exhaust and not the carbon version and that the tech installing my system will put in a less than perfect map.

Can someone tell me if I should be using the Akrapovic full exhaust map or a Yosh or some other brand when tuning for the Akra carbon exhaust?

any downloaded map off a site is hit or miss. I have found even ones that are labeled exactly for your needs many times are pretty poor maps

just wondering why you went with the pcv instead of an ecu flash that offers so much more for less money and adds no extra equipment to fail

I can vouch for how poor the Dynojet maps are. Ive used several, specifically for my bike, and exhaust, in the past... They were terrible. It was better riding with stock fueling in all cases.


A PCV really needs a dyno tune, or at the very least, an autotune module, to even get close.

I've been using the 22-058-502 map whilst waiting for my BMC air filter to arrive before I get a custom dyno tune done. A friend of mine has just removed the Akra Ti with the 22-058-502 map and fitted the Akra Carbon with the same map, he had it on the dyno and no adjustment to the map was required apparently... :rolleyes:

I'm still going for a custom dyno tune once the air filter arrives and I can get a slot booked in at the dyno center... better safe than sorry :D

So, what Im saying is, try them all, and use the one that your butt tells you is best. Unfortunately, you won't get real close to optimal with a Dynojet map.

I do agree with Vcyclenut though. The ECU corrects all of Yamahas flaws, and improves fueling and timing to create a better package. Dynojet, I believe offers an ignition module, of course $$$

Sorry, that is only on select models, they don't offer an ignition unit for the FZ

I made a map using dynojet's maps.. I wound up pasting parts of akra map after 6k rpm from 5% throttle forward in 4th-6th gear, and parts of the yoshi and graves map up to 7k rpm / 5k in 1-4 gears... Basically cutting up the dynojet maps and combining them...alot of trial and error... But i ended up with a map that feels awesome and torquey with the perfect amount of engine braking.

I was getting exhaust popping around 4k and 6k on decel so i added fuel and tapered it down around those rpms in the 0% bracket... First thing you wanna do it calibrate your throttle though to align the map to the correct throttle positions.

I'm fairly new to the motorcycle world and tuning.. It was recommended by my local Yamaha mechanic that I get some way to control the air/fuel when swapping out exhaust systems so he suggested getting a PCV. I didn't want to remove the chip and mail it off to be flashed so I figured it was easier to have an inboard way of tuning. I'm not opposed to getting my bike dyno tuned now that it has a PCV and I would even consider getting the Auto-tune unit installed if that will help.

Most mechanics are not familiar with ECU flashing... Looks like someone already posted about a Frankenmap that you could probably procure.

I'm so green with this stuff I would even know where to begin at this point, I assume you need a laptop or some way to connect to the PCV? I just looked around my area and the pickings are pretty slim for dyno tuners. There's a few but they all seem to specialize in Harley V-twins.

I wouldn't head to a Harley specialist...

You need a computer with a USB port, download the Dynojet software... after that the connection is easy. Then you need to download maps from Dynojet, or another user with a better map.

The PCV is for guys who want to take a real hands on approach to tuning their bikes.

In time, piggyback controllers like the PCV will be obsolete... current technology is surpassing their capabilities very quickly.

Since I did go the PCV route do you recommend I also get an Auto-tune to adjust for changes in climate?

I am considering getting mine flashed and i have the pcv...I also have the ti can so i dont know if that makes a difference...I like all the throttle characteristics and looked over the sites options for the flash pretty nice....I DO NOT want the engine braking messed with is my concern I like it suits my style perfect...

No...

Your ECU will compensate with small trims, just like every bike that comes off the assembly line does. The Auto Tune also doesn't make changes to fueling until after you ride the bike, log into your PCV with a computer, view the trims it suggests, and accept them... it isn't always adjusting fuel tables, it is much more manual than that.

an auto tuner works well if you put a mapping switch on it so it only tunes when you want it to and you ride the bike in a very specific manner while tunning. Just placing the autotuner on the bike and riding it will not make a good map. YOU will find your trims never get close to zero which is what you want.

MOst dealer mechanics and small shop mechanics still think of ecu flashing as some kind of black magic. They dont understand it, what its capable of, and the fact it is a very safe option at this point.

They will also blame anything they can on an ecu flash if you bring a bike in for service. My favorite was when a dealer mechanic told one of my costumers his slipping clutch was due to my ecu flash. The guy thought I was blowing him off when I said that was impossible and his clutch was just bad. After returning his ecu to stock and then the mechanic telling him I must have messed up his ecu, I finally convinced the guy to ask them to put a stock ecu of a bike in the showroom. Surprise!!, it still slipped. ughh

Domestic engineer?......Domestic engineer?...hmmm.......
Is that like when my wife makes me a sandwich? Or determines how much detergent to put in the dishwasher?

Ok so I picked up my bike this morning and rode to work and my initial impressions are: Love the tone and sound over all but the damn backfires and pops have to go!:mad: I backfires on almost every gear change. If I get the bike dyno tuned can the poping and backfires be completely removed?
