Your check engine light is on because you are not providing the proper signal that used to come from the oxygen sensors. Install the sensors in your new exhaust (yes, drill it and put them back in), then connect the wiring correctly and it will work.

Location of speed sensor 2007 street glide


Hi Anonymous, always check your instrument fuse before performing the next procedure, try cleaning your speed sensor located on top of the transmissions right side between the top cover and the chrome starter end cap on Twin Cams and on top of the engine case between the rear cylinder and the starter motor for Sportsters. Remove the the bolt that secures the sensor and pull it out of the transmission. Inspect sensor for obvious damage and repace if necessary. If sensor has no damage then wipe clean any obvious contamination like micro fiberous material with a clean rag and reinstall, torque bolt to 8 ft lbs.

How do you adjust the timing on the 08 street glide?


You don't. It's controlled electronically by the crank position sensor in the front of the engine case. This sends a timing pulse to the ECM and it sets the timing. Now, the dealer may be able to adjust the timing but the owner is not unless you have installed a "break out box".

Good Luck

You are correct … partially. The ECM monitors the O2 sensors to keep the fuel/air ratio at around 14.7:1. This happens only at cruising speeds or light engine loads above idle. At wide-open throttle, the sensors are not being monitored. When you change the intake or exhaust tracts, you need to change the fuel mapping at wide-open throttle and possibly at idle. In between, the O2 sensors will keep the fuel/air ratio at the 14.7 range. This may or may not be the best for your engine package and riding requirements. Power Commander has what you need to make it right. You can use the O2 sensor eliminators and adjust the fuel/air throughout the rpm range or just tweak the top end at wide-open throttle.
