М11 (Korvet)

Forum: http://forum.chiptuner.ru/forumdisplay.php?f=266

 

KORVET М11.3х
is the new generation of ECUs to replace M10.3х model. Like M10.3х, they can be installed to sports cars, boats and other vehicles. Fuel supply can be controlled via mass air-flow sensor (MAF), manifold absolute pressure sensor (MAP) or throttle position sensor (TPS).

All М11.х ECUs are equipped with CAN bus.

Depending on their configuration, KORVET 11.x ECUs support the following options and functions:
— 2 to 8 cylinders
— Max engine speed 15000 rpm
— two- and four-stroke IC engines;
— Rotary engines;
— Turbocharger system and mechanical supercharger
— ANTILAG mode — turbine maintenance during gear shift
— Turbotimer mode
— Valve Timing Electronic Control (VTEC)
— Control of two injector rows with separate injection phasing for each of the 8 injectors
— Phasing control based in start and end of fuel injection
— Linear lambda control within engine operation range
— TWINSPARK system control (two spark plugs per cylinder)
— AVTOSTART and ANTIBUKS functions
— Gear shift assist (for dog clutch gearbox)
— Electronic throttle control
— Nitrous oxygen injectors control  or in combination with “dry” nitrous system

Besides, М11.3х ECUs can be optionally equipped with built-in logger (nonvolatile memory 16 Mb) and accelerometer. Logger stores main parameters. Parameter list can be adjusted. For accelerometer-featuring models, angular acceleration values are logged as well.
A built-in logger paired with GPS receiver BR-355 logs coordinates and speed of the vehicle at any time.

Currently the following models of KORVET M11.3x ECUs are produced.
