So I had a little bit of a scare yesterday. I now have everything hooked up (headers, cat bypass, Akrapovic, KewlMetal air filter, PCV, O2 Optimizer and AutoTune. Before I put the bodywork back on, I wanted to make sure it runs. Getting sick of waiting for warmer weather, I decided to pull it out into the driveway. It was 35 degrees, I turned on the ignition, hit the start button and it fired right up. All joy quickly faded when I saw the check engine light come on
After letting it run for a little while, I noticed that the temperature reading on the display was bouncing all over the place. It was going from -70 to +50 degrees. It was all over the map. I shut it down and decided to do some research. Come to find out, If the temperature sensor (AAPTS) gives incorrect readings, it will cause the check engine light to come on. I was glad to discover that as it explained what I was seeing. I then opened my shop manual for the Spyder to determine where the temp sensor resides. Much to my surprise, it resides in the frunk. When I saw that, a smile came across my face as I had not put the frunk back on yet, meaning that the temp sensor was disconnected.
Today, I got the frunk out of the basement, brought it to the garage and put it back on the bike. There are 8 connectors that needed to be hooked up and then the wire to pop the lid of the frunk. Once completed, I rolled the Spyder back out to the driveway. Today it was just 15 degrees, but I didn't care as I had to verify that the problem was resolved.
I hit the start button and it fired right up with NO check engine light. It is gone. I stopped and restarted the bike numerous times throughout the day and the light is now gone - as it should be now that the temp sensor is hooked up. I let the bike get a thorough warm up and made sure the fan kicked on. It sounds great and the throttle seems to be much more responsive than before. With the cat, stock air box and stock muffler gone, I'm sure the engine is no longer choked up.
At this point, I am extremely pleased that adding the PCV, O2 Optimizer and AutoTune is working just fine with no issues. That was my biggest fear. I'm now going to proceed with putting the bodywork back on and and getting it ready to ride
