What is ECM link?
ECMLink provides enhanced logging functionality (MUCH faster than factory) and all the tuning tools you need to run any number of different configurations from bone stock cars on a stock MAF to 11-second road course beasts on speed density to 8-second drag cars running a GM MAF.
Is speed Density better than MAF?
Answer: A MAP sensor (speed density) is better for forced induction since a MAF sensor’s pipes will take up needed space in the engine bay. Also, front-mounted intercoolers will interfere with the MAF sensor’s accuracy as it can introduce air turbulence.
What is tuning for speed Density?
Speed Density tuning relies on a calibrated “Volumetric Efficiency” (VE) percent for each engine speed (RPM) and air density (typically Manifold Air Pressure). For each engine speed, and manifold pressure, there are values in a VE table to specify how efficiently the motor is running in those conditions (Below).
Does speed density use O2 sensors?
Production-based Speed Density computers also utilize an oxygen (O2) sensor mounted in the exhaust tract. The computer looks at the air/fuel ratio from the O2 sensor and corrects the fuel delivery for any errors. This helps compensate for wear and tear and production variables.
What is tuning for speed density?
Which is better MAF or speed density?
Speed density is the older but more sophisticated method of fuel delivery. The MAF is out, and this system relies on a combination of the MAP sensor and an intake air temperature sensor. These two data points are used in conjunction with the ideal gas law to create a volumetric efficiency table.
Is speed density better than MAF?
How do you remap an engine?
An engine remap is performed by writing a new software program onto the engine’s electronic control unit (ECU). This is a relatively simple method of tuning, usually done by plugging a laptop into the car’s OBD port (the same plug most garages use to diagnose a problem with your car if it breaks down.)
What is checksum in ECU?
A checksum is a value that is calculated from a block of digital data with the scope of being used in the future to verify if this data has been modified in any way. So basically if you change any of the maps in your cars ECU the currently saved checksum/s will not be correct and your car in most cases will not start.
What are checksums in tuning?
A checksum is a value that is calculated from a block of digital data with the scope of being used in the future to verify if this data has been modified in any way.
