I DID SOME MORE TESTING WITH THE ETHANOL TODAY ,I HAD 4 GALLONS OF ETHANOL THAT I BOUGHT TWO WEEKS AGO AND DECIDED TO PUT IT IN AND TEST IT THE OTHER NIGHT I TOPPED OFF AGAIN AND THE PERCENTAGE OF ETHANOL DROPPED TO 55 FROM 57 ,AT WOT THAT DROPPED A 1/2 DEGREE OF TIMING FROM 18.5 TO 18 ,WHEN I ADDED THE 4.5 GALLONS I HAD AT THE SHOP THE ETHANOL WENT BACK UP TO 57.5 % AND WOT WENT BACK TO 18.5 ,,,I DROVE OUT TO THE PUMP AGAIN AND FILLED MT GAS CANS UP WITH 20 GALLONS OF FUEL AND TOPPED THE HELLCAT OF WITH ANOTHER 4.4 GALLONS ALL FOR A LITTEL LESS THE 50 DOLLARS ,,,
THE ETHANOL CONTENT WENT UP TO 68% THEN SETTLED TO 62.5 % I DID A WOT PULL 3RD THRU 5TH ,,TIMING AT WOT NOW IS 20 DEGREES AND STILL NO KNOCK RETARD, IN MY TUNE 21 DEGREES IS THE MAX SO I WOULD ASSUME ANOTHE 3% OF ETHANOL WOULD GET ME THERE ,ALSO BEING ITS THE FIRST PART OF THE TUNE I ASSUME CURT WOULD HAVE TUNED IT ON THE SAFE SIDE ,,MUST SAY THE ETHANOL IS IMPRESSIVE AND NETS AWESOME POWER
55% = 18.0 TIMING
57.5 = 18.5 TIMING
62.5 = 20 TIMING
