Dynojet Power Commander 5

This Power commander was really easy to install and to program. The extra power it produced with my new exhaust is amazing. I would definitely recommend this!

This item doesn't have the ability to adjust ignition timing from what I read. It has the oxygen sensor removal resistor plug ins for both sensors and is meant to be used without the factory oxygen sensors. I installed it on a 16 Harley low rider S 110 ci bike. It came with the stock map and the bike ran just like normal after installation. The bike at that time was all stock. Wiring harness and unit location allowed for just the right amount of room for installation and fitment of the extra harness and plugs x2 in that left side ecu housing. It is a bit tight, but with proper routing it fits in perfectly.

PC5 installation was easy and straight forward on my Triumph 675R. Bike has an aftermarket filter and full race pipe. Downloading a map was also very easy. Throttle response felt snappier immediately. Even on the stand. Then put the bike on the dyno for a custom map. Picked up 7hp at 9000rpm. Nice jump in midrange. Look forward to track season to fully test it out.

The unit was very easy to install on my 2003 GSXR600 maybe 20 minutes, the bike picks up a lot quicker now, smoother power, bike starts up and idles a lot smoother as well. Great product highly recommended.

Only rEason it didn't recieve all 5 stars is the directions don't exactly tell you where the lower injectors are and there are no maps for high altitude
Other than that it is great

You feel a big difference in throttle response and power.

I have a 2006 ZX14 that I recently removed the secondary throttle plates on. This was a must for the increased air at lower RPM and also helped with decal popping. The install was straight forward and came with instructions on how to do everything from removal of fenders to uploading maps. On power commanders website there's software that must be uploaded to a computer to transfer the fuel map/trim to the module

Increased power.

I'm not one to really write reviews, but I had to on this one. I made mods to my bike gradually; changed the stock muffler, installed a M4 y-pipe, and then finally put in this PC5. After changing the muffler, I didn't notice much difference in performance. However, after I installed the cat eliminator, my bike ran horribly. I lost a lot of power in the high and low ends. On deceleration, it was popping and just didn't have the feel I liked. THEN, I installed the PC5 and sent it the map for the Olson mid-pipe... OMG! TOTAL 100% improvement! The PC5 straighten out everything and my bike is back to being Bae! I also installed the Graves block-off plates and those took care of the few minute pops left after the PC5 install. I would definitely recommend this if you're making exhaust or air mods.
