- | ====== Running E85 (or E70 or Exx) ====== | ||
- | When running a mix of ethanol and gasoline, you have to account for the difference in fuel makeup when calculating your global fuel adjustment. Some common numbers you'll need for this are provided below. | ||
- | |||
- | ^ Fuel ^ Stoich AFR ^ | ||
- | |Gas | 14.7| | ||
- | |E70 | 10.6975| | ||
- | |E85 | 9.8526| | ||
- | |E100 | 9.0078| | ||
- | |||
- | To calculate these values, use the following formula: | ||
- | |||
- | <% ethanol> * 9.0078 + <% gasoline> * 14.64 | ||
- | |||
- | For example, for running pure E85, you would use: | ||
- | |||
- | 0.85 * 9.0078 + 0.15 * 14.64 = 9.8526 | ||
