So, I installed a Doebeck Gen3 on my softail over the weekend. I shopped around quite a bit in my search for a better efi than what came stock with the bike, and after reading the comments on other threads, went with the Doebeck. I got a great price on it too - 30% veterans discount! I'm on a 2012 FLSTC that I picked up a year ago. I had earlier added the SE Stage 1 Air kit, Rush 1.75 slash cut slip ons, and had the stock ECU flashed after that. The Gen 3 is with the bypass, so I was able to take the o2 sensors out of the loop. The process wasn't as easy I thought it was going to be. Here are some of the things I ran into: - I had to pull the tank. I had removed the air cleaner on the right and the pulled the horn aside on left, and I just could not get my hands on the injector sockets. It was much easier after pulling the tank - but - the tank is a bit more hassle. The crossover fuel line is a little tricky. Pick up a couple of hose clamps before you start and make sure you've got something to catch the gas. No matter how empty you get the tank, there will be some residual - With the bypass, you have to plug the pigtail that runs from the sensor. I ended up using some good electrical tape to cover the pin sockets, and then put shrink tubing over that. It'll last for quite a while. - I would have liked a better place on the bike to mount it. No side covers, and room under the seat is limited. I have it velcroed to battery. - The unit came with 3 zip ties, but I added a couple more to make sure the wires were routed like I wanted them. 3 wasn't enough. I was concerned when I hooked it up to power. The first and last led's on the face of unit alternated red/green flashing as soon as I attached the ground wire.. Doebeck says this us a connection error, but I triple-checked everything. After about 10 seconds that stops, and the bike started right up. I did the test run today - no issues at all, and the lights look normal. I've got an email in to tech support - I'll post the response when I get it. The test ride went very well. I noticed a slight increase in torque, but the better change was how smooth everything was. Acceleration, downshifting all seemed much better. A better power curve though the gears. Bike seemed to run cooler too, but not really easy to tell: I have an oil cooler installed, and the bike already runs cool. And maybe it's me, but vibration seems less too. All the pops I was getting on downshifting are gone! I would occasionally also get a pop when shifting from 2 -3 and 3-4. All gone. Next, a set of cams! That will likely be the last thing I do to the bike. If anyone has any questions, feel free to ask away!
