Who doesn’t like watching cars doing big wheelies down the track? In most cases, it’d be the driver and his crew. Why? Well, as spectacular as they may be, uncontrolled wheelies can cost you valuable fractions of a second and potentially cause damage to the suspension and even the chassis.

Why do cars wheelie?

The best examples of big wheelies can be found on a drag strip, that’s because drag cars tend to have the right recipe for lifting the front end – big power and incredible grip through the tyres to the sticky racetrack.

When a drag car launches from the start line the rotational momentum of the rear wheels overcomes the weight of the car in front of the rear axle. The rear axle then acts as a pivot point forcing a weight transfer from the front to the rear. As the front end lifts, transferring even more weight rearwards, less and less force is required to lift the front it even higher.

How high the car lifts depends on several things: the power the engine makes at each RPM point, the weight of the car, the speed of the car, the suspension setup, the centre of gravity and the wheelie bar setup (if the car has them).

Controlling a wheelie

There are two ways of controlling a wheelie. The mechanical option is to fit “wheelie bars”. These are mounted directly on the rear end of the car and are height-adjusted to the amount of allowed lift. While this is a common sight on many drag cars, some classes do not allow them.

The second option is to control the front-end lift using an ECU with a Laser Ride Height Sensor.

How Does It Work?

Once mounted, the Haltech Laser Ride Height Sensor measures the distance from the sensor to the ground and feeds that information to the ECU. We can then set up a maximum lift distance and map the ignition and fuel against the front-end lift and the road speed.

To put it simply, when the front end lifts, the ECU will start cutting ignition or fuel or both. Once the front end comes down and makes contact with the ground the ECU restores the fuel and ignition to its original setting.

To prevent the front end from coming up again we can delay the return to the normal fuel/ignition map using the Timer function in the Torque Management setup. This will allow the car to settle, pick up speed and transfer some weight onto the front end.

Mounting

We recommend mounting the sensor near the steering rack and between 3″ – 5″ from the ground at static ride height. However, your application may vary and require some adjustment.

The actual laser lens (red panel) needs to be pointing downwards and the wiring harness connection either to the right or to the left. Mounting the Laser Ride Height Sensor incorrectly can result in incorrect ride height readings and trigger an incorrect response from the ECU.

Wiring

The Haltech Laser Ride Height Sensor comes pre-terminated with a DTM3 connector. If used with an HT-141376 (Elite 2500/2500T V8 Big Block/Small Block GM, Ford & Chrysler Terminated Engine Harness) then this sensor may be plugged directly into SPI4 on the engine bay harness with no modification.

With custom or universal wiring use the following pin-out:
PIN 1: Ground, PIN 2: +12V or +16V DC, PIN 3: Signal.

NSP for Elite ECUs

Ever since we released the NEXUS R5, people have been telling us how much they like the Nexus Software Programmer (NSP) Software.

Creature comforts like the intuitive layout, multiple display themes, and adjustable font sizes make it a nicer software package to use than our earlier Elite Software Programmer (ESP), and because of that we were often asked if you can use NSP to tune an Elite series ECU. Well, now you can!

Compatibility

The new Elite Firmware 3.00 makes all Elite ECUs compatible with NSP. This update covers all models of Elite ECUs: Elite 550, 750, 950, 1000, 1500, 2000 and 2500 as well as the Elite VMS. It doesn’t matter whether you bought your Elite yesterday or when it first came out, this update covers ALL Elite Series ECUs. Best of all – the upgrade is FREE for all Elite users. Think of it as our 35th birthday gift to you.

What you get with this upgrade:

• Dramatically faster connection speeds to the software
• Loop Logging for Elites and improved data logging setup
• On Board Oscilloscope for all Elites
• Trigger and home voltage readout in scope available for Elite2500 and 1500
• Individual setting password protection
Plus all the other NSP goodies like Advanced Quick-Tune, Undo/Redo on any change, and the improved layouts.

How to update your ESP to NSP on your Elite ECU:

Step 1: Download the new version of ESP here: www.haltech.com/downloads

Step 2: Install the new ESP software and go online with your Elite Series ECU.

Step 3: Under the “Tools” menu select “Update ECU for use with NSP Software”.

Alternatively, if you already have the latest software version, you can use the ESP Online portal to access the most current version of Firmware for your Elite ECU and update it.

IMPORTANT: Before updating the Firmware on your ECU always disconnect your ignition system.
