GEN3 EJK Install on a 2008 FLHX
Hey everyone - I was one of the fortunate moderators that was given the opportunity to evaluate the Dobeck products. I'm not an engineer or a scientist so my review won't be as technical as some would like but I sincerely hope it will be helpful. And be forewarned - this is a long post so make sure your coffee mug is full!
I decided to install the GEN3 Electronic Jet Kit on my bike first. I ride a stock, 2008 Street Glide (FLHX.) By stock I mean no modifications at all to the air cleaner, headers, mufflers, or fuel delivery system. My main goals at this time are simply to cool the motor down a bit because of the added fuel and get a slight increase in performance, especially high gear roll on situations like when you have to pass someone on the interstate.
WEBSITE
There are actually 2 websites you can refer to. The main Dobeck site is
EFI - Electronic Fuel Injection Controllers - ATVs, UTVs, Motorcycles, Snowmobiles, Scooters, Sport Bikes, Watercraft while the site for the GEN3 EJK is
EFI Controllers - Electronic Jet Kit - Motorcycles, ATVs, UTVs, Sportbikes, Snowmobiles, Watercraft, Dirt Bikes. The Dobeck site is larger and actually has more information. The EJK site is helpful but many parts of it are labeled "Information being gathered. Please contact us for information."
DELIVERY/PACKAGING
The EJK (Electronic Jet Kit) arrived as you would expect in a sturdy cardboard box. Inside, the product was encased in hard, protective plastic. Included were the fuel controller, instructions, quick reference card, zip ties, velcro, and oxygen sensor bypasses.
INSTRUCTIONS
The very first thing I noticed was that everyone who works at Dobeck must be under 30 years old with super human 20/10 vision. All of the instructions fit on the front and back of a single sheet of standard 8 1/2 by 11 paper. But to accomplish this it was necessary to use a small font that had me instantly scrambling for some reading glasses!
A Factory Service Manual is a valuable tool to augment Dobeck's instructions. Step 2 says to "locate fuel injectors on the throttle body." It then goes on to explain where you would find the throttle body, but referring to Figure 4-26 on page 4-22 of the 2008 Touring Service Manual made it abundantly clear what I was looking for. Anytime I'm going to disconnect something from my bike, I want to be 100% certain I've got ahold of the right object!
Finally, nowhere in the instructions does it tell you to disconnect the factory wires to the oxygen sensors and install the included bypasses. I confirmed that this was a correct thing to do with a quick phone call.
INSTALLATION
I am an absolute novice when it comes to using tools around a Harley, but it only took me 2 hours to totally install the EJK system. And I did a lot of extra stuff that others may decide to skip, mainly the total removal of the fuel tank, seat, side covers, and saddlebags. The fuel tank is the big time consumer in this list but I'm glad I took it off. It made it so much easier to access the fuel injector harnesses and I was able to route all the wires through the plastic channel where all the other bike wiring goes. Made for an extremely clean installation.
Other than what's already been mentioned, the instructions were clear and well illustrated. My only suggestion would be to add one more step. After you connect the EJK male to the factory female (which previously was attached to the injector) both of these assemblies hung down under their own weight and dangled much too close to the cylinder heads for my comfort. I was able to zip tie them up higher and out of the way and I would suggest that this should be added to the instructions.
TUNING
The bike started right back up after everything was reassembled. Man, you should have seen me holding my breath - did I mention what a rookie I am?
I wanted to reset everything back for a stock bike since the EJK comes shipped with the settings for a Stage I already in it. It took me a long time to get the hang of using the Mode, +, and - buttons. The instructions mention that the Mode button can be sensitive and they are NOT kidding. I finally used a lighter touch and got it to cycle normally through all the modes and got everything set back to stock.
My plan is to go for a ride tomorrow morning and start to experiment with adding some fuel in the different modes and see how the bike reacts and if I can achieve my goals that I set out earlier in this post.
