I Live in Country so most Runs might be at least 10-18 Miles , a few 7-8 Miles and Toss in 2 round trips of 60-90 miles .. Generally , but in the Hills and lots of Stop signs - Traffic Lights on short Runs ..many Cold Starts . .
The 400 mile Tank was longer Runs .. Bigger Mountains and some Spirited Driving .
It seems , When I reset after the Last Tank which was Mid Grade - that the Fresh Reg. Tank was doing Very Well ..
( Believe the Computer takes it's Time ) Dialing Back the Timing Advance - it had Leaned - Picked up from the Mid Grade Tank - where I had some High HP - Runs also ..
The Weather was 12 degree Cooler then it had been also . Then Filled with Regular - it seems the Timing Stayed Advanced for Few more Days , Possibly the Cooler Weather
As it started to Drop another few Degrees , so (90's were Gone , then the 80's - Turned into 75's ) I Believe the Leaned Computer - just Kept the Advance do to Light Driving & Cooler . .
What this Tell Me is there is Room for ECO Improvement - with - Temperature Controls , so Lets Say
Cool Air Intake - system that Breathes Better & ( Better IC for Hot Weather )
400 Miles Tank didn't have the Engine Bay Hood Seal - Removed - all the Others Tanks _ Had Removed the Engine Bay Seal .
Once I realized just How Hot this Engine Bay was in 92 Plus Heat - that was Off !
Now this Week - were having Mid 60's & 45 @ Night , so the Engine Seal is back on now .. Just Yesterday it took 10-11 miles to get Motor Full Warmed up Trans didn't Warm Up
Another 5-6 Mile .
Oil Isn't , but Water Gauge is Reporting Fully Warm , but has Never taken 11-12 Miles to get Trans Fully Warmed Up .
Now it's even Cooler so Seals On and today 5- Miles Engine Warmed , 8-9 Miles Trans Felt Smooth ( Felt Warmer ) - I tell by the Firmest of the Shifts and It was 56 Degrees , so that Seal
Removal makes a Difference . . 75 Degree and Up . .
