Driving In The Centre Of A Cell
01.27
| 00:00 | - Once you have mastered left-foot braking, you can start using it to navigate your way around the cells and the fuel and ignition maps. |
| 00:07 | Again, this will seem awkward and difficult at first, but after a little practice, you'll find that you can be very accurate in highlighting an individual cell. |
| 00:16 | When we're making changes to a fuel or ignition cell, we want the ECU to be centred in that particular cell. |
| 00:23 | The ECU will interpolate from surrounding cells if the operating point is overlapping two or more cells. |
| 00:30 | For the best accuracy, we want to make sure we're adjusting the cell the ECU is accessing. |
| 00:36 | Using the throttle and the brake pedal, you'll find that you can very accurately hold the engine in a specific cell. |
| 00:43 | It does take a little finesse to make subtle changes to both the brake and throttle, to make small changes to where the ECU is accessing. |
| 00:51 | If you need to increase the load, you'll need to use more throttle, but at the same time, this will probably require a little more brake pressure, too. |
| 01:00 | After awhile, this will begin to feel quite natural, and you'll be able to move around the maps without really needing to think about it. |
| 01:09 | Before I make changes to a cell, I try and hold the engine steady for a second to let the AFR readings stabilise. |
| 01:16 | This again lets you know that you are accurately making changes based on the true operating conditions of the particular cell. |
