AMP PNP Initial Configuration

Jump to: Engine Displacement | Fuel Injector Size | Wideband Setup

Before startup its important to double check settings that are often effected by upgrades. This is not a complete list of parameters that may need adjustment, but is intended to cover the basics needed for a successful first start. 

Required Fuel

Here we are able to make changes to:

• Engine Displacement
• Injector Size

In TunerStudio, go to Basic / Load Settings > Engine and Sequential Settings, then select Required Fuel.

Engine Displacement

The base tune is configured for the factory displacement. If your engine size has been altered from stock due to overbore or stroker kit. Update the Engine Displacement to match your new displacement.

Injector Size

The base tune is configured for the factory injectors. If your vehicle is equipped with a different injector size, you will need to update this setting in the tuning software. Update the Injector Flow value to match the injectors installed on your vehicle, using either lb/hr or cc/min

• • Injector Deadtime Values: while not absolutely required, if you are running large injectors taking the time to update deadtime values will often lead to an easier time getting the tune dialed in. See MS3Pro Injector Deadtime article for details.
  • Air-Fuel Ratio: Gasoline use 14.7 if your running E85 use 9.8, if you want to tune E85 in the gasoline scale please navigate to Basic / Load Settings > General Settings and change the Stoichiometric AFR to 14.7

Wideband Setup

This section covers the settings required to configure the wideband system used with your ECU. Setup options include an internal wideband, external analog wideband, external CAN bus wideband, and multiple wideband configurations. Be sure to select and configure the option that matches the wideband hardware installed on your vehicle.

Jump to: Internal | External Analog | External CanBus | Multiple (Dual/Individual)

In TunerStudio, go to Fuel Settings > AFR / EGO Control, then set your EGO Ports as needed for the wideband configuration being used.

Internal Wideband

If your AMP Plug-N-Play ECU is equipped with an internal wideband, select AMPEFI Wideband. No further action is required, as the calibration is already built into this selection.

External Analog Wideband

Once your external analog wideband is wired to the ECU (Wiring a Wideband Controller), select the correct Analog Input under the EGO Port section in TunerStudio based on the input used on your ECU.

After that, update the ECU with the correct calibration for the wideband controller installed on your vehicle. In TunerStudio, go to Basic / Load Settings > Calibrate Lambda Sensor and select the appropriate calibration for your wideband controller.

External CAN Bus Wideband

Many wideband controllers support connection through CAN bus. When using a CAN bus wideband, set the EGO Port to CAN EGO.

Next, configure the CAN wideband settings under CAN-bus / Testmodes by selecting your wideband controller in the Fetch EGO Data dropdown menu.

Multiple Widebands (Dual/Individual)

When using multiple widebands, all additional widebands must use the same wideband controller type. The ECU only allows a single wideband calibration selection, so all connected widebands must match that calibration.

Multiple CanBus Widebands

To add multiple CAN bus widebands, first select the Number of Sensors connected to the ECU. Then, under EGO Ports, set each additional wideband input to CAN EGO.

Multiple Analog Widebands

To add multiple analog widebands, first select the Number of Sensors connected to the ECU. Then, under EGO Ports, assign each sensor to the correct Analog In input used for that wideband.
