Steering Wheel Button / Multi Axis Stalk

...

...

NOTE: The 3 button stalk cannot map switch when rolling (due to cruise being active) there is also NO Set button press to activate custom maps ECU connect could be used instead.How to map switch on a steering button multi axis stalk

  • Press and Hold “Res” for 3 sec (the map switch should now be displayed on the Tach)

  • Use the (plus) and (minus) buttons to select different MS modes

  • press set to confirm the mat switch mode or allow it to time out.

if you wish to change the RaceROM controller for Boost or Power

  • Press and Hold “Res” for 3 sec (the map switch should now be displayed on the Tach)

  • Press “Res” again to enter RaceROM controller for Torque and use the (plus) and (minus) buttons to increase and decrease the controller

  • Press “Res” again to enter RaceROM controller for Boost and use the (plus) and (minus) buttons to increase and decrease the controller.

  • If you keep pressing “Res” it will keep cycling through the MS mode or RR controller adjustments.

  • Press “Set“ to exit.

How to map switch using the 3 button stalk

  • Slide switch to “CANCEL” and hold for 3 seconds (the tach should mode to your current MS mode)

  • Use the (plus) and (minus) buttons to select different MS modes

  • allow the MS mode to time out and tach returns to normal

EA888 3 Button Stalk Map Switching.mp4

Enabling Map switching is a simple as selecting the number of modes you wish to use and then populating the MS mode maps that you need to tune. Map Switch mode descriptions for ECU connect can be used so the car owners using the ECU connect App know what each MS mode is tuned for e.g. 91 octane, 95 octane and e30.

...

These maps emulate the OEM maps which would no longer need to be tuner the RaceROM ignition maps can be live tuned as required.

NOTE: The idle and flap closed maps the OEM maps have not overwritten and will need to be tuned if you wish to change the timing in these low load conditions.

Ignition Timing Mode 1-4 & Lift

...

If you are using the output to control the exhaust flaps with custom maps you must set the duty to match the open and close duty requirements of the valve (10% for closed and 90% for open).

NOTE: the Output frequency is adjustable but the OEM signal output voltage is 5V and low current capable, The 5V supply will need to be converted using an external controller to a 12V signal. there are commercially available 5V to 12V PWM converter circuits (fast acting SSR 80A DC SSR (50V), or High-Current Solid-State Relay or https://www.holley.com/products/nitrous/controllers_and_accessories/parts/15620NOS) don’t forget back EMF protection diodes.

Custom maps

Custom Maps are blank map that you can configure the inputs and outputs (as well as activation parmeters) to perform a task that isn’t covered by another hardcoded RaceROM feature. Custom Maps gives tuners the ability to add their own general-purpose maps to control key engine parameters such as ignition, fuelling, boost target, cam angles, wastegate position and more (listed below). They also integrates with the ECU Connect app to give drivers the ability to make adjustments to their tune using the app within the boundaries set by their tuner.

o   Repurposing the Exhaust flap control systems give us 2 Frequency based outputs that can be used to drive a Boost control solenoid at a desired frequency, from there you can simply set a custom map up to drive the output at the required duty.

  • Traction control

o   Using the Wheel slip input parameters you can set up a slip based traction control system using custom maps outputs to manage the torque timing and boost as required.
