Rotary Ignition Split
Factory Rotary engines use 2 spark plugs per rotor. Both spark plugs in a common rotor are not fired at the same time. ere is a delay between the
time when the leading spark plug is fired, and when the trailing spark plug is fired. MoTeC wrote special software to be able to mimic this type of igni-
tion control for rotaries in the M4 and M800/880. A table is available to define differing amounts of timing split to suit any application and driving
condition. Of course if you do not wish to use the split timing function MoTeC can accomodate that as well.
Auxiliary Tables
MoTeC Engine Management systems are extremely adaptable to differing engine requirements. One way MoTeC makes this possible is through the use
of Tuner definable output controls. A 3 dimensional table can be selected by the tuner with several inputs available to use as the table axes. Typically
Engine RPM, Engine Temperature, Air Temperature, Manifold Pressure, rottle Position and Auxiliary Inputs are available to set up the table. Tun-
ers typically use this type of control for engines which have switchable cam profiles such as the Honda V-Tec. e 3D table can be set so to rottle
Position versus RPM for example and the tuner can turn on the V-Tec based not only on RPM but also load so the cam timing can be optimized for
varying loads.
Fully Variable Camshaft Timing
MoTeC is proud to be the industry leader in the aftermarket for controlling engines with fully variable camshafts. We have several special modes
written to allow full control of up to 4 fully variable camshafts per engine such as the Dual Vanos BMW V8 using our M800/880 series of Engine
Management Systems. Special Ref/Sync modes were written to allow the tuner to use the stock trigger wheels and sensors. Camshaft timing can be
independently adjusted for each cam in 1/2 degree increments based on RPM and Load. With full adjustment of camshaft opening and closing points,
the engine’s volumetric efficiency curve can be stretched providing optimum cylinder filling over a much wider range of RPM, increasing the average
horsepower and ultimately making the car faster.
Drive by Wire control
MoTeC is the first in the industry to adopt drive by wire throttle control using OE components. Many of the newer models of cars are equipped with
electronic throttle control. MoTeC retains all of the standard redundant sensors that the factory uses for safety. In addition to very precise control of the
throttle position, throttle by wire also incorporates idle speed control and traction control. MoTeC Drive By Wire is available for certain Bosch, Delphi
and Nissan systems using our M800/880 series of Engine Management Systems and we are working on additional Drive By Wire systems on a daily
basis. If you are interested, please call to discuss your system’s requirements.
Telemetry
All MoTeC products offer the ability to transmit data from the ECU using a 3rd party radio, to a PC using another radio, for real time monitoring
of engine functions. e Telemetry option allows the ECU to transmit this data over the radio’s and MoTeC’s Telemetry Monitor software allows the
tuner to view the data remotely. Note that Telemetry is for real time analysis only. No data storage is done on the PC, however the ECU will still be
able to log the data.
Remote Logging
When used in conjunction with the MoTeC Telemetry option, remote logging allows the data which is monitored with Telemetry Monitor, to be stored
on the PC and converted to a data format which is readable using MoTeC Interpreter, our data analysis software. Note that the Telemetry option must
be enabled in order for Remote Logging to function.
