I'm sure someone is gonna yell at me but b4 you switch back can you do a few tanks of 93 to test for mpg vs 87? As this is my dd mpg is my first concern so I would like to know if the extra cost of 93 can be offset by better MPGs
ECU ability to adapt to pump 93 testing
So I been running a test and been posting to the other forum and did not want to cross post to it unless ok'd by a moderator.
Heres a quick rundown:
I have switched over to pump 93 on my second tank and noticed a improvement in performance.. I have a PLX multi gauge reading my ODBII values. SInce the switch and emptying out the factory fill at 700 miles and going 3 tankfulls same shell station same pump I have gone from +3 timing at WOT to +6. It pulls really hard now so what my plan is is to do 2 more tank fulls and if it dosent advance timing any further I will switch to 87 and see if it pulls timming back to compensate for the lower octane. Hopefully this will end the regular vs premium debate over performance. Also when I get the chance I will do a stock dyno to see if my AFR is rich or not and see what numbers its pulling.
I would rather not have to repost each forum but I will in the name of VT Science
Mods please let me know if its cool as its good info to have across all VT owners
If anyone is running stock and has a stock dyno with 87 showing AFR that would be helpful info.
