Data Collection for your small race bike? Heck yeah!  But, why, you might ask do I need this, Well, a full Break down is at the bottom of the listing, but if you want the absolute best in performance, then this is one page of paragraphs you have to read!


HM/Spears Racing Yamaha R3 ”WURX” Data Logger kit is the result in several hours of dedicated people/companies to bring the end user the best Data Acquisition data logger for the R3. This kit starts with the HM M3 Dash   the Worlds most advanced, accurate and reliable PREDICTIVE GPS lap timer and does everything your standard dash does and more, a lot more. For example, on some model bikes the dash will tell you how many liters of fuel is in the tank, or what the oil level is. Graphical backlit LCD Multi-color LED’s for RPM / information and warnings Automatic display for stationary warm up / checking and then will switch once you start riding to track mode display.

The HM M3 Plugs into your stock dash connector. No wiring and no configuration needed – simply plug whatever sensors you want in. All of the available data from your ECU is logged (the M3 communicates with your ECU automatically).Mounting bracket is also included so that the Dash M3 simply bolts into the same place as the stock dash and sits in the same place.

The R3 does NOT have TPS (Reader on the Dash). So you will need to run a wire from the TPS sensor to ‘TPS’ on the back of the M3.(Supplied in Kit)

On the R3, there is a fairly simple OE dash connection. It has Temperature, RPM, Speed (RWS), Fault Codes, and a few others. NOTE: For Speed to be present, speed must be viewable on the stock dash. If the stock dash does not have speed (because the speed rings have been removed) then the M3 will not have speed.

Each dash comes with the Machined 60/61 aluminum dash risers, and anti vibration mounts.

Choose Your Sensor

Simply plug the sensor into a dedicated connector on the back of the Dash – NO WIRING OR LOOM OR CONFIGURATION etc required.

For example, the following dedicated connectors (and more) are on the HM/Spears Racing R3 ”WURX” Data Logger:

Front Suspension
Rear Suspension
Brake Pressure
Rear Wheel Speed
Lambda (02)

Front and Rear Suspension: Potentiometer are manufactured to Spears Racing specifications and will be the best unit to run to get the most accurate/movement on your front and rear suspension on your Kawasaki Ninja 400cc, the units are light the front weighing in at 2.90 oz./82g and the  rear weighing in at 2.10 oz./60g and has an aluminum outer housing and is mounted to the custom Spears Racing engineered mounting kits with stainless steel m4 socket head cap screws and brass threaded inserts.

Brake Pressure: sensor is inserted into the back of the dash for the “front brake”, this Brake Pressure Sensor is custom built to HM/Spears Racing  Specs and will work on the HM M3 Dash Boards and will be used with HM data logging products. The custom front brake line that the brake pressure sensor will mount to is built to Spears Racings Specifications and comes with all of the necessary “Copper Crush Washers” and a new “Double Banjo Bolt”‘

Rear Wheel Speed: However many Dash connections have speed in the data or discreetly, and so a wire from the speed sensor is not required, the M3 simply picks it up.(the R3 has the ability to connect in the stock Loom).

Lambda: (o2) Not Included in Full Kit (Add On)

For the sake of clarity: No bike (or car) comes with a wideband lambda sensor. To log lambda you need a wide band lambda sensor. So if the bike has a lambda sensor already it is irrelevant, if you want to log lambda you will need the lambda kit from Spears Racing.
Do you need to log lambda? That depends on why you are logging.

If you are logging to also view engine performance and fueling and you intend to make trackside adjustments, then YES, you will  need a lambda. This is because, with the best will in the world, a dyno on a modern bike does not put the bike in the same environment as on the track. It is usually close enough to setup fueling on a dyno, but to get the most out of a bike, you should then (after setting up on a dyno) look at the AFR after practice etc, and tweak the fueling accordingly.

Differences are – availability of clean, cool fresh air without turbulence, load differences (air resistance, big hills etc) and the area of the throttle used most in the important areas (initial throttle opening and WOT). Fueling on initial (and just prior to initial) throttle opening plays a huge part in how the bike feels and how easy it is to ride on the edge of the tire…
A really rich 0% to 2% map will make the bike burble and gently come into power, a really lean of the same will be spiteful – just have to make sure that you do not flood, and the lambda trace on track will tell you about that.

Example: In a dyno room, the air is typically hotter and of a different humidity than out on track. That should not matter because most bikes have Air Intake temperature, Air intake pressure and atmospheric pressure sensors and one would think that they adjust the given fueling perfectly for any conditions, sadly this is not the case. These parameters are non-linear and complex and so the ECU does it’s best job to compensate for this, but that is never the same as fueling in those actual conditions. For 99% of customers, you do not need lambda. For the 1% that are willing to ‘go the extra mile’ to get the most from the bike, then Yes.

WHAT IS ALL THIS ABOUT ANYWAY?

Data acquisition as the name applies is all about information gathering. Technicians and tuners have always had the challenge of trying to make educated changes on a motorcycle to improve performance solely based on the rider’s feedback and hand signals.

Data gathering is divided into two sections, engine and chassis. Engine data gathering can be kept very simple or incredibly complex. The most basic entry-level engine monitoring system is going to record engine RPM, rear wheel speed and lap time.

The HM/Spears Racing data acquisition system will come with a HM M3 dashboard to give the rider the requested information. This very basic information can quickly tell you your maximum speeds, minimum speeds and when compared to your RPM, detailed gearing information can quickly be established. This data will also let you monitor sections on the racetrack to see if you are quicker as you do standard chassis and gearing changes with accurate and reliable PREDICTIVE GPS lap timer. Rear wheel speed sensor for wheel spin. Throttle position sensor could be added to watch for the riders input to the package.

If you were serious about monitoring the fuel injection, you could then add a live o2 sensor (Lambda)into the exhaust to monitor the air/fuel ratio coming out the tail pipe. This info, coupled with the TPS (throttle position sensor) would allow you to customize your fuel mapping not in a dyno room, but live, on track at speed for perfect mapping!

Chassis data gathering can be far more complicated and harder to decipher than engine data gathering. Engine data can usually be looked at and then compared to a base line earlier determined to be optimal. If it’s too lean, richen it (By adding a Lambda Sensor) if the revs are too high in an important corner consider changing the final drive or transmission ratio to bring them down, this would be a faster/better off corner speed.

Chassis data, on the other hand, typically requires a lot more experience from the technician to decipher. Typically attached to the suspension of a WSB or Moto GP bike will be front and rear potentiometers (pot) or Linear Displacement Transducers (LDT’s) , measuring front and rear wheel position compared against time. This little bit of data can provide a ton of information such as maximum wheel travel, average position, suspension sag, and rate of travel change to name just a few.

You will look over the data, looking at where the suspension is in the travel as the rider brakes, turns into the apex, releases the brakes and accelerates out. They are watching for how much the front forks dive, how fast they dive and how quickly they recover. They will then watch the rear of the bike during the same period, is it tracking over the bumps at full extension, is it squatting appropriately on corner exit? All this info combined with the riders feedback will help them make changes to the preload, spring rate, compression and rebound.
A good chassis technician can determine from a few laps at speed around a racetrack. Other Chassis sensors may include front brake pressure sensors in the brake line, to monitor when and how hard a rider is squeezing the brakes.
