Added is an interface for data acquisition
This interface is connected to a computer and consists of the following modules :
Atmospheric sensing module, this measures absolute pressure, air temperature and relative humidity. These measurements are used by the software to correct power and torque measurements to standard atmospheric conditions according to a DIN, SAE, ISO, EEC, JIS norms.
RPM module, this receives and processes signals from up to 2 inductive pickups for measurement of engine RPM.
Dynamometer input/output module: this sends and received data from the dynamometer and the hand held pendant.
CPU module : this contains a 32 bit processor which acquired data from the expansion modules an communicates to a main computer running the WINPEP software.
Air Fuel Ratio module : this measures the amount of air and fuel in the exhaust , now you can measure in all RMP and throttle positions if your fuel system gives a perfect response response
It is important before we start tuning the fuel system that the following has been done : valve clearance, carburetor synchronization, good spark plugs, air filter, chain and sprockets, chain tension, tire pressure.
Our tools to make your motorcycle run good and more effciantly:
Dynojet offers a wide range of kits to fit any application. Several types (stages) of kits are available to fit your specific needs.
Stage 1 Kits Intended for motorcycles with a stock engine using the stock airbox, air filter and stock pipe. Stage 1 kits are fully adjustable to allow the use of a well designed aftermarket pipes and stock replacement air filters like K&N. Stage 1 kits are designed to improve throttle response and driveability and in most cases power increases of approximately 5% throughout the entire power range can be achieved.
Stage 2 Kits Intended for motorcycles with a stock or mildly tuned engine using a well designed aftermarket pipe with a modified airbox and a stock replacement air filter. Stage 2 kits are designed for applications where individual filters cannot be installed and for applications where airbox modification improves the engine's performance. In most cases power increases of approximately 8% can be achieved.
Stage 3 Kits Intended for motorcycles with stock or mildly tuned engines using a well designed aftermarket pipe and individual air filters. In most cases power increases of 10-15% can be achieved. However driveability may be compromised particularly with short stroke, high rpm motors. On some modern engine and airbox designs, individual filters and proper jetting offer no performance improvement yet compromise driveability, in such cases stage 3 kits are not available. Stage 7 Kits Intended for race only use or for special applications, like the Yamaha V Max complete induction kit.
Stage 7 kits are designed to optimize jetting for a given tuning specification or racing conditions.

PSL - DYNOJET POWESPORTS DYNAMOMETER
Dynojet’s inertia dynamometer (dyno) is a measuring device for recording and
displaying power and torque of an engine. The model 250i we have here in our workshop has
an integral Air/Fuel ratio module for advanced real time diagnostics an automated atmospheric condition monitor for accurate and repeatable CF values and an air brake system for 2 stroke engine testing, and has load control capability to simulate real road conditions.
Firstly we start by discussing in depth your engine and carburation set up, Jet Tech Pro software is used to enable a bench mark based on supplied data such as venturi diameter, jet/needle type etc.
We then perform typically 4 -5 runs based on RO ( roll on ) and AG ( all gears ) to build an accurate picture of your engines performance all with air / fuel ratio, other runs such as FA ( Fast acceleration ) and NG ( Negative Horsepower ) can be performed if required.
The costs of tuning on the dyno can vary depending on what you you want to achieve, we charge a flat rate of £45.00 per hour and include the workshop facilities to make any adjustments between runs, please allow 1 -2 hours for the testing and analysis.
Explanation of terms used:
POWER
Power, in mechanical terms, is the ability to accomplish a specified amount of work in
a given amount of time. By definition, one horsepower is equal to applying a 550
pound force through a distance of one foot in one second. In real terms, it would take
one HP to raise a 550 pound weight up one foot in one second. So to measure
horsepower, we need to know force (in pounds) and velocity (in feet per second).
The force applied to the drum is calculated from acceleration using Newton’s 2nd law, (F)orce equals (M)ass times (A)cceleration.
TORQUE
When an object rotates around a point, the object’s speed of rotation depends on
both an applied force and the moment arm. The moment arm is the distance from the
point of rotation to where the force is being applied. Torque is the product of the
force and the moment arm. For example, if a rope, wrapped around a drum of one
foot radius, is pulled with 550 pounds of force, the resulting force is 550 foot-pounds.
The Torque on the dyno’s drum can be calculated by multiplying the force applied by
the drum’s radius. However, engine torque is not equal to drum torque because the
gearing through the drive train changes the moment arm.
CORRECTION FACTORS
Correction Factors are used to compensate engine horsepower measurements for
differences in operating conditions during engine testing. The typical correction
factor (CF) is calculated based on the absolute barometric pressure, air temperature
and water content of the air used for combustion by the engine under test. The
correction factor attempts to predict the horsepower that would be developed if the
engine were tested at sea level under standard pressure and temperature conditions.

AbsHg = RelHg - (Elev/1000)
Where:
AbsHg is Absolute barometric pressure.
RelHg is Relative barometric pressure.
Elev is test location elevation in feet above sea level.
RUN TYPES
• RO - Roll On , wide open throttle acceleration from low RPM to maximum RPM without changing gears.
• AG - All Gears: a type of dyno run test where you accelerate though all of the gears. This test is particularly useful for clutch diagnostics.
• FA - Fast Acceleration fast acceleration: a type of dyno run that starts at a high RPM and then accelerates to redline quickly.
• NG - Negative Horsepower the dynamometer calculates horsepower (negative) by measuring how fast the drums decelerates. Negative horsepower can measure how much power is absorbed by your drive train and other parasitic losses (transmission, drive shaft, and tire friction).
• CP - Horse power at the clutch
