| Still, some folks may want to simplify their tuning efforts and focus on a single row at all times. That's fine too, just keep in mind the expected results. | Still, some folks may want to simplify their tuning efforts and focus on a single row at all times.

| - | When this box is checked, you'll want to change the WGSGear table in Direct Access on the WGSMisc tab to have values related to the raw LatestSpeed variable (instead of the raw WGSGearRatio used by default). | + | When this box is checked, you'll want to change the WGSGear table in Direct Access on the WGSMisc tab. The default values are based on an internal (raw) ECU value named WGSGearRatio. If you want to base gear selection on speed instead, then you'll need to change this table to reflect values from the internal ECU variable named LatestSpeed. The following screen shot shows the WGSGear tab in direct access. |

| - | Display LatestSpeed on your graph using the Raw value -> button in the Display Values dialog. | + | The values shown above are the default gear ratio values provided in ECMLink. These values would select Gear 1 when WGSGearRatio is below 158. Then it would select Gear 2 when WGSGearRtio is between 158 and 248. Then it would select Gear 3 anytime WGSGearRatio is above 248. |

| + | The ECU provides some internal hysteresis to limit sudden switching between gears. | ||
| + | |||
| + | To change these values to reflect speed instead, calculate your speed points as: | ||
| + | |||
| + | WGSGear value = (speed in mph) / 1.2425 | ||
| + | |||
| + | So, for example, if you want to select 2nd gear at 40mph, you will use 32 as the Gear 1 value. If you want to select 3rd gear at 80, then you'll use 64 as the Gear 2 value. | ||
| + | |||
| + | You can also display the raw ECU value called LatestSpeed on your graph using the Raw value -> button in the Display Values dialog. That's the value the ECU will compare against when doing gear selection based on speed. You can use those values directly in the WGSGear table. | ||
