Throttle Setup Proxima.

The throttle limits is calculated by the Proxima during pedal TPS calibration. This process will determine opening and closing power to control the throttle gently. It differs between different throttle manufacturers and must be adjusted for each type. If you load a map from a similar throttle then it should be working.

The MAP accelerator pump in the ECU software is used for the throttle adjustments. Note that the text in Red is not in the software but only for explanation which blocks to adjust.

To adjust these values first zero all both of them. The throttle will then have no power on it and it should show the resting 0%.

To adjust throttle opening duty and gain.

Put the ignition on. Do not start the engine.

Put the TPS graph, Water Temperature and Idle-control off. Also put low limit duty cycle to 0.

Calibrate of the TPS if you have not done it yet. When you save after Pedal TPS calibration, the ECU will open and close the throttle automatically.

Now press and keep the throttle in completely. Look at the throttle TPS in the real time screen on the POT bar. Now use the arrows of Opening Duty and increase the value till the throttle open above 95%. Remember this value. Now reduce the value till the throttle close to below 5%. Take the average of the two values and set opening duty to that value. In this example 115(to open) + 75(to close) = 190 / 2 = 95. Now release the throttle. If you press it again, the throttle should not open.

Now press the pedal fully and increase the Opening gain slightly. The throttle should open to about 99%. You may increase the value till you get a fast enough response and the throttle follow the pedal value. If the gain value is too high the throttle will vibrate. It should be around 4. Save the settings to the device.

This value is the minimum opening that the TxW will control the butterfly. Now you may start the engine and adjust the Low Limit Duty Cycle till the engine idles on its own. Let the engine get up to working temperature and adjust this setting till the engine runs at the desired idle RPM minus 100. This will allow the TxW to control the idle faster. You may now proceed to idle control setup.
