I forgot to mention, a vendor sent me some LED lights to try out. They sent me a pair of headlights, and a pack of interior lights. I've installed the headlights already, and am pretty impressed. I agreed to make a video about the headlights, so no spoilers yet.
Also, I changed jobs. The new job has a different driving pattern, which has affected fuel economy. I'm still going to keep tracking fuel economy, but I don't think I'll be using that to judge ecomods anymore. Too many variables. Instead, I'd like to do a coast-down test. Maybe after the weather cools off, so I can have the A/C turned off.
We can see if the first round of ecomods have made a noticeable difference. Then we can move on to round 2, which would be the belly pan and maybe rear wheel spats?
