Features
- Record engine HP and torque for each individual cylinder, during each run down the dragstrip
- Display variations in HP and torque from one cylinder to the next
- Display variations in HP and torque from one combustion cycle to the next
- Record cylinder filling (volumetric efficiency) for each cylinder
- Record combustion pressures for each cylinder and the location relative to TDC
- Record the rate of air/fuel mixture combustion (mass fraction burned) for each cylinder and every combustion cycle
- Detect detonation on as few as 1 in 100 combustion cycles
- Display detonation magnitude and pinging frequency for each cycle with detonation
- Record pressures in the intake/exhaust ports during valve overlap
- Record pressure in the intake port at intake valve closing
- Evaluate differences in combustion properties between fuels of different brands/octane ratings
Hardware
- Data logging up to 1.8 million samples per second
- Compact, lightweight, rugged, easy to assemble/disassemble
- Metal military quick disconnects and metal overbraid shielding
- ICS (In-Car Systems) products for professional competition (up to 8 pressure sensors, crank sensor, numerous digital inputs)
- DBS (Dyno Based Systems) products ranging from 5 to 30 pressure sensor inputs
- LCS (Low Cost Systems) products for the budget minded
- LCS and DBS units can also be used for in-car applications by connecting to a laptop computer (USB port) installed in the vehicle
- Minimum PC requirements for data analysis software - 1 GHz processor, 700 Mb RAM, Windows XP (Home or Pro)
Software
Data is displayed for each and every combustion event as well as in a series of overall test summary formats.
Over 20 data plot formats including:
- HP, torque, IMEP vs. rpm and time
- combustion pressure vs. piston position
- detonation intensity
- air-fuel mixture burn rates vs. piston position
- combustion efficiency
- volumetric efficiency vs. rpm and time
- port pressures during valve overlap
- intake port pressure vs. piston position
- exhaust port pressure vs. piston position
- exhaust stroke back-pressure
- individual cycle and overall data summary
- plots of multiple cylinders overlayed
