eBoost2 basic setup & tech tips

eboost2 Setup

Turbosmart's eBoost2

Turbosmart’s eBoost2 is a fully-featured programmable electronic device. If you are a competent, technically-savvy DIY installer, we suggest you carefully read and follow the instructions included with the unit.

Simple Setup Guide

Despite being a state-of-the-art electronic device, an eBoost2 is relatively easy to set up. While we recommend you get your e-Boost2 set up by a qualified technician who will help you get the most out of the product, you can still get the basic functions working for you by following this Quick Start Guide.

1. Set the SP Value

The SP value determines the duty cycle the solenoid will operate at when the gate pressure is reached. This is a value between 0 – 99. The larger the value, the higher the duty cycle, the more air the solenoid will bleed off from signal to the wastegate, the more boost the turbocharger will produce.

Start the setup by increasing the SP value to 10. Bring the car onto boost and see what the maximum boost pressure is. Increase the values in increments of 10 until the boost achieved is close to the value desired. Then increase or decrease the SP value in small increments until the desired boost level is achieved.

The SP value can also be adjusted while the car is on boost however, instead of the SP value being shown, the boost pressure will be displayed.

2. Set the Gate Pressure

The gate pressure is the pressure at which boost pressure begins to act on the wastegate.

This changes the turbocharger’s response and the rate at which the boost increases to the desired boost pressure. The gate pressure will always be lower than the desired boost pressure as the wastegate needs time to open and control exhaust gas flow.

Start by setting the gate pressure 5 PSI below the boost pressure achieved with the corresponding SP value. Bring the car onto boost and check whether there is a boost spike. If there is no boost spike and you want to increase the turbocharger’s response, you can increase the gate pressure until you get a spike, then reduce the gate pressure until the spike is gone.

Alternatively, you can lower the gate pressure to change the ramp rate of boost. This can be used in situations where the rise in boost is too aggressive and causes undesirable wheel spin.

3. Set the Sensetivity

The sensitivity is how sensitive the eBoost2 is to changes in the boost curve. Under normal circumstances, the sensitivity is left at the factory set level of 20. If your boost curve is wavy through the rev range, change the sensitivity to 15. If your boost curve drops off at the end of the rev range, change the sensitivity to 25.

Repeat these steps in all of the boost groups you have selected.

e-Boost2 Troubleshooting

After installing the eBoost2 or eBoost STREET my engine is over-boosting/under boosting.
• Check that the e-Boost solenoid is installed correctly.
• Ensure the factory boost control solenoid is not connected in the hose between the pressure source and the wastegate actuator
• Ensure the length of the wastegate actuator rod has not been modified, refer to the manufacturer’s specifications.
If the over/under/irregular boost is still occurring…
• Check to see if the eBoost solenoid is not blocked or contaminated with dirt, oil build-up or debris
• Check the joining hoses for splits, cracks or loose connections and ensure they are not blocked, kinked or restricted, particularly if the
the existing hose was reused
• Pressure test the wastegate actuator for leakage, the diaphragm or housing may be cracked or split

If the over/under/ irregular boost is still occurring…
• Ensure the smooth and free operation of the wastegate arm in the turbo exhaust housing.
• Check that the hose between the eBoost and the inlet manifold is not obstructed, broken or kinked.
• Double-check that the OBS is set higher than the boost pressure you are aiming for.
• Check the Blow-off Valve for leakage, some are used as over-boost valves

If the over/under/ irregular boost is still occurring…
• Gate pressure may be set too close to your actual boost pressure – ensure correct sensitivity setting.
