19.3 mpg over 220 miles to & from work... no pinging on Arco regular. Going to re-tweek the fuel pump parameter a bit more to see how far it can go. Started at 125-> 115 -> 105. will do 100 next unless there is pinging, then will bump up until it stops. Lower limit is 100.

 

next update done, pings @ low rpm low vacuum conditions. Tried a few things to get it to stop with no luck. Going to get back to it later today/tomorrow and triy again.

 

Update of sorts... have not changed the tune from the above post, pinging stopped. temps are supposed to climb this week, will see if it comes back.

But... on another note, did a 100% dgas tank over the last 2 days, 325+ miles 17.1 mpg. Speeds in the 60-78 mph range with 2 passengers. Was 100% shocked it was that high, was guessing it would be mid 15's.
