“HOW YOU DO ANYTHING,
IS HOW YOU DO EVERYTHING.”
TUNING SERVICES
Have you ever used a household vacuum or home hairdryer? Ever put your hand over one end of the hair drier and heard the motor spin up and it gets much louder as it struggles? Or have you ever had your vacuum clogged and the motor whines and is audibly different? This is the same thing as your motorcycle engine. Air is sucked in through the intake, compressed, mixed, and ignited in the combustion chamber then blown out the exhaust. Just like your vacuum, or hairdryer, if you alter how much air comes in or how much air can exhaust out you can choke the motor and reduce power and cause other damage.
In-House DynoJet 250l Eddy Load Brake Dyno
Motorsport Exotica offers specialized tuning services designed to unleash the full potential of your motorcycle. With a range of options, from dyno testing and mapping to advanced tuning systems like Motec, Woolich and MRCK. Explore our tuning services and experience the difference that professional tuning can make, whether you ride on the track or on the street.
What controls your motorcycle? What is the actual brain of the bike? What makes the engine run and how can it be manipulated to be better? The ECU, along with proper tuning and/or mapping is the answer to all of the above.
Do you know the difference between a base, de-restricted flash, or custom map? A piggyback vs ECU direct? Individual cylinder mapping or unified group?
These are all things that are discussed and offered here at Motorsport Exotica. We boast one of Southern California’s only Dynojet 250I Eddy Load Brake dynamometer machines. Used daily for mapping, diagnostic and testing purposes. This tool is vital to any performance based facility.
Custom tuning gives us the capability to get your engine running optimally. Correcting AFR values, working on ignition timing, setting ETV values and tuning on/off OEM restrictions. These are all major points that need to be addressed when building a proper machine.
There are a wide range of variables, and variations, as to what can be done based on your specific. Send us a message requesting tuning information and we can discuss all available options and what to expect from each one.
Tuning Cheat Sheet
A dyno is a dynamometer machine. This is a tool used to run a bike in a controlled environment, at varying speeds and conditions, while recording input from various data throughout the motorcycle. The rear wheel of the motorcycle spins on a large roller, while things like industrial-size fans produce wind to create true riding simulations.
AFR refers to Air Fuel Ratio. This is the stoichiometric number of the amount of air to fuel in the combustion chamber of the engine. This number is very important to creating the correct burn for optimal power and efficiency. This number is generated by reading the exhaust gasses leaving the cylinders. This number changes all throughout the RPM range and throttle request so it is not a one size fits all.
This is the correlation of what your wrist and throttle tube is doing vs what the ECU is actually telling your engine to do. How much to open the throttle blades on your throttle bodies based on your throttle tube request. There are 2 styles of this system. STP and Full ETV.
• STP is found on almost every fuel injected bike but it’s being phased out currently. This refers to Secondary Throttle Plate systems. Meaning, when you turn the throttle you are physically controlling 2 cables that are manually turning a cam wheel opening up one of two throttle plate sets. The ECU is reading this request and controlling the second set of plates in relation to what you’re asking for.
• The newer style of throttle plate control is ETV or Electronic Throttle Valve. This means when you turn the throttle you are sending a digital signal to the ECU to control the throttle bodies/plates. This is a newer technology and is what a lot of riders complain about when they refer to a jerky throttle. As OEM settings can be set for US emissions restrictions and not actually ideal for a rider or optimal performance. Bottom line, ETV or Throttle Mapping refers to the correlation of what you’re doing with your throttle tube vs what the engine is actually being told to do.
A tune / tuning is the process of creating new mapping. Using tools to read out engine performance output, a tune can either generate a new map, or adjust the existing one.
• Refers to 'mail-in' mapping, where the bike is either not present and/or not ran on a dyno to create it.
• Created by tuners, they work 99% of the time, and are compatible with a wide variety of machines.
• Safe to run on various bike types.
• Derestricted maps or base flashes may or may not include changes related to: ETV/STP, AFR changes, ignition, speed limit, AIS system, exhuast system and temperature settings.
• This is considered the baseline, or industry standard, set of changes for any general tune or map.
What a flash / flashing includes is highly variable from one tune to the next, but this is just the term for the actual process of writing an ECU map.
