Efficiency Axis
00.54
| 00:00 | One important aspect of a VE based fuel model is that the load axis for the efficiency table must be set to manifold pressure. |
| 00:08 | The VE model uses the ideal gas law to calculate air mass based on engine capacity, air temperature, and manifold pressure, hence manifold pressure is a key metric in the equation. |
| 00:21 | This doesn’t present a problem in most situations where we would normally be using manifold pressure as the load input anyway. |
| 00:29 | If you are tuning an engine running multi throttle bodies however you may prefer to use throttle position or Alpha-N as the load axis. |
| 00:38 | This isn’t strictly possible in a true VE based fuel model but the M1 offers a work around to allow the efficiency table to effectively be tuned off throttle position. |
| 00:49 | We will look at this in more detail further into the course. |
