PCV and Auto Tune Kit Review
About 2 years ago, I put a full exhaust on my 08 GSXR 600 after only running a slip-on for the longest time.
The slip-on didn’t affect the bike much, but changing the header and removing the cat did! My bike really just ran like crap. My choices were to keep riding it as is, put the stock exhaust back on or get the PCV. What to do? Well one day I heard my co-worker Todd talking non stop about track days. He loves them and that’s the only riding he wants to do. Hearing him got me thinking I want to do them as well. But I can’t have my bike running like garbage on the track, so I splurged and bought the Power Commander V.
I thought it would be a simple plug and play install, but it turned out to be a little more involved. The plugs for the lower fuel injectors were squished behind a plethora of wiring harnesses, servo motors, etc. On top of that, it seemed like some of the plugs didn’t match up. I actually had to give up and put the bike back together without the PCV. I gave Dynojet a call and got a few tips and found out that I had grabbed the wrong plug for the Throttle Position Sensor. Once I figured out which plugs I needed to get at, I had the PCV installed in about 20 minutes.
I went to install the software onto my Macbook so I can download the appropriate map, only to find out that Dynojet does not like Macs and doesn’t support software for them. What a bummer. I had to call around asking my friends to borrow their Windows based laptop so that I could tune my bike. Surprisingly, this is something not many people are comfortable with, but finally someone agreed. I finally got the map onto the PCV and noticed a difference as soon as it started because it actually idled and didn’t stall out. However, it still had a hesitation at low RPM.
I rode it for a bit and tried to tweak the map, but I couldn’t figure out how to get rid of the hesitation. Luckily for me, the guys from Dynojet were here to train us on the PCV and the Auto Tune Kit. After hearing the benefits of the Auto Tune, I decided to pick one up and see if it will fix my problem.
I had to get some help from another RZ staffer, Uncle Loomis, to help out with welding a bung for the sensor to my header. Once that was complete, the rest of the Auto Tune install was a breeze. I noticed a difference right away on my ride home from Loomis’s house. My throttle response was so crisp!
I’ve done several track days since adding the PCV and Auto Tune and the bike runs better every time. My bike is now an animal! My final analysis of these two Dynojet products is that they aren’t the easiest to install as claimed by Dynojet, but well worth the trouble once you get everything hooked up.
