0:10 Pump E-85 Dyno Results
0:34 Our last champ up to this point is VP MS103
1:00 We used regular pump E85
2:00 After having issues we decided to test ethanol content with our Daytona Sensors WEGO III http://thetuningschool.com/product/da...
2:15 We actually had E-40
2:40 Why was E-40 actually ok for our application?
3:00 Getting enough fuel is always an issue
3:39 Why 130% Injector Duty cycle is bad for direct injection
4:40 We pulled each run to 6200 rpm during this series
5:20 We like to see this AFR with Forced Induction
5:50 We got 24 degrees of timing
6:15 New champ E85
6:30 Look at the Averages
7:00 34 more HP on Average over MS103
7:10 Peaks ended very close
7:30 It wasn't the timing that made the power-it was the fuel
8:00 Pros and cons
8:06 Con-pump inconsistency
8:40 If you are going to run E-85 all the time you really should do a flex fuel conversion
9:10 You will be paying your tuner for extra time -tuning for E85
9:25 8-9 Pulls to dial in E-85 vs 3-6 pulls with other fuels
10:00 With E-85 you have to tune startup, cold start, hot start, part throttle idle until you get to WOT
10:25 Cold starts are a known issue for E-85 in cold climates
10:50 Gas mileage?
11:00 IDC- Injector Duty Cycle-what to watch for
11:41 Hardware expense for E-85 conversion/ Flex Fuel conversions
12:20 Can you pump handle E-85? Can your hoses? Can your tank handle it?
13:00 usually you will need bigger injectors- We recommend http://thetuningschool.com/infinityin... with data
