Without knowing the exact details of the damage on your bike, all I can do is make a suggestion. If the "Towrag" has managed to get power to the ignition side of the switch the ECU or PowerCommander may be shorted. This could cause the starter to run but not firing pulse to the plugs. Check for a spark at the cylinder. No spark - could indicate a fried ECU or commander.

I have 2008 gsxr 600. I recently had a power commander and a carbon fibor slip on exhaust put on and now at higher rps, I get a FI light that kicks on I had it back in shop and they tried fixing it but...


Hi the power comander is easily removed as it runs in series with the bikes orIginal wireing, you simply remove the wire connectors from the injectors and the original connectors and the bike is back to normal while they send the power comander back to dynojet, its not unusual for the wires within the dynojet plugs to become faulty poping out of the block as you push the 2 connectors together, does your bike have 8injectors, 4 low rev controled and 4 higher rev controlers, as per instructions You must plug into the correct injectors, if the unit is faulty it will be replaced under warranty, with the pc 111 removed ride the bike and check if the fault still exsists, was the exhaust sensor wire removed
And the o2eliminator fitted, this gives the pcomander full controll, never heard of a faulty one , heard of one that didn,t work. I would phone dynojet uk, if you live in uk, tell them the problem etc, tellephone(0)1995500600

I only have the dyno jet i dont have the usb peace whats an even good point to set the fuel at directly from the box with the 3 buttons its self?


The power commander uses a mini-b USB cable that you can get at most any electronic store or Walmart for next to nothing.... if you've got a digital camera, you've probably already got the cable you need. You'll just need to download the software for the Power Commander from http://www.powercommander.com/downloads/Support-Released/PCIIIUSB/Software/PC3Usb%203.2.1%20Setup.zip.
Once you've installed that one your computer, you'll be able to tweak your fuel map however you want. I would recommend making a backup of the fuel map that you're running right now before making any changes, that way you can go back to stock without any trouble. Dynojet's website also has canned maps for all kinds of bikes that you can download, and for the most part they work great.

Unplug the power commander first. It could be bad. They occasionally are defective. If it cures up the problem, then contact who you pruchased it from. if it doesn't make sure the mapping is actually for you application. it could be running on the rich side and it's taking a little while to finally load up.
