Thanks Jolivas : Good Catch - I have to scratch My Head and wonder why No One has mentioned this like 2 Years ago ..
I'm also wondering If Honda has found - Knock sensors to be so Very Sensitive that ~ Road Noise ~ ! also Translates into Vibs on Knock Sensor . .
As My MPG with new "Lighter Wheels"
Is Improved , but Mostly in the Average Cruising Range 50-65 Mph up above 70 Mph to 80 Mph No Improvement @ All
Even with Tire which are Proven Better Mpg with Less Rolling Resistance . .
That said - New Rims are a Tad Wider , Not as Aerodynamically Designed . . Makes Me Pause thou and Think those little Tweaks shouldn't be doing this . ?
Hence My Wondering , as it seems These Wheel Items Honda Engineered are a Bit Much for Honda to Go that Far out on Limb for Sound ,as there are ~ Plenty of Lightweight Materials
~ to Reduce Sound ..
NOT have to " Reinvent the Wheel "
Then I Factor in - No Reports from Other Lightweight Wheels be added to Accords Dropping 40-49 lbs , NO One has Mention Better MPG . .
I Know for Fact on Other Vehicles in Past ( Lightweight Wheels ) Always meant 1-1.5 Mpg on Older Rides ..
We have Chassis that may not be as Heavily Built , Materials being more Sound Sensitive , Sensors & Engine Computers @ Lighting Speeds , may just be Adjusting Out Timing
~ Due to Vibrations from Road Sounds ~
