1. Turn the ignition to accessory so the cluster and converter have power. The engine does not need to be running.
2. On your phone or laptop, open the Wi-Fi list and join S2000-Cluster. It can take fifteen seconds or so to appear after power-up.
3. Your device will warn you the network has no internet. That is expected — stay connected to it.
4. Open a browser and go to 192.168.4.1. Type it exactly; some browsers will try to search for it otherwise.

The line under the title tells you which unit you have. This manual covers the GPS Edition. If yours says CAN Edition, you want the other manual.

Cluster type. AP1 and AP2 clusters need different signals, so the converter has to know which it is driving:

• AP1 — 2000 to 2003. 7 coolant segments, 7 fuel segments.
• AP2 — 2004 to 2009. 20 coolant segments, 10 fuel segments.

This sets the speedometer scaling and reloads the gauge tables for that cluster.

Advanced mode. Adds a per-segment fuel threshold table to the Fuel tab, for setting each switch-over point by hand instead of from five calibration points.

Restore defaults. Returns the coolant thresholds and fuel calibration to factory values for your selected cluster. It does not touch your cluster type or speed calibration.

Device info shows the Wi-Fi name, the address to connect to, and the firmware version installed. Update Firmware at the bottom opens the update page covered in the last section.

It shows three things: whether the receiver has a fix, your speed in mph, and how many satellites it is using.

The badge reads No Fix until the receiver locks on. The first fix after the unit has been unplugged for a long time can take two or three minutes. After that it is usually within about thirty seconds, because the unit keeps its almanac on a backup battery.

Once it reads 3D Fix, the speedometer is live. Four or more satellites are needed for a 3D fix; more is better.

Satellite speed is already accurate, so unlike a sensor-driven setup there is nothing upstream to go wrong. This setting exists for the other end of the chain: cluster-to-cluster variation, and a factory scaling constant that may not suit every car.

1. Hold a steady speed. Higher speeds give a more accurate result.
2. Note what the Speed reading at the top of this tab says, and what the cluster says.
3. Enter both under Speed calibration and press Calculate & apply.

Use the same unit for both numbers. The correction is saved immediately and applies from the next moment the speedometer updates.

In the example the cluster was reading 5% low, so the correction becomes 105.3%. Cluster shows is the converter's estimate of what the dash should now be reading, which is a quick way to confirm it took.

The adjustment compounds, so you can refine it. Drive again, check, and enter the new pair — each pass gets closer rather than starting over.

Reset returns to 100%. You can also type a percentage directly if you already know the figure you want.

The Coolant tab shows the gauge as the cluster displays it, the current sensor reading, and how many segments are lit.

The Thresholds grid sets where each segment switches on. The heading says ADC below = segment on: as the engine warms the sensor reading falls, so each threshold is lower than the one before it. Seg 2 lights first, and the last one is the hot end.

Enter the first and last values you want and press Extrapolate to space the rest evenly, then Save to device. The box with the amber outline is the segment currently lit, which makes it easy to see where you are on the scale while the engine warms up.

The Fuel tab shows the gauge as the cluster will display it, the raw sensor reading, and which segment is currently lit.

Calibration takes five numbers — the sensor reading at empty, quarter, half, three-quarters and full. Enter what you know and press Extrapolate to fill in the rest, then Save calibration.

Auto-learn is easier if you can run the tank down. Press Start, then Set empty when the tank is empty and Set full after you fill it. Press Commit to save. The converter works out the points in between.

1. Before you go to the car, download the firmware file for your edition from s2000cluster.com. The converter's network has no internet access, so you cannot fetch it once connected.
2. Connect to the converter as described earlier in this manual.
3. Go to Settings and press Update Firmware.
4. Choose the file you downloaded and start the upload.
5. Leave the ignition on until it finishes. The converter restarts by itself.
6. Reconnect and check Settings → Device info shows the new version. This manual documents 2.2.0-GPS.
