The Meteor86 direct injection inductive kit is based on the Meteor86 ECU to which is adjoined a DDi08 inductive driver for driving the inductive injectors which need a high tension and current command.
• It allows managing 1 to 8-cylinder engines in direct injection. If it controls 8 injectors, it has only 4 remaining ignition channels and therefore the ignition must be in twin spark mode.
• It can manage engines in line and 'V' engines as well, with a separated management for each bank of cylinders (intake, Lambda, turbos, fly by wire and camshafts for each bank, variable valve lift).

Several tunings can get along for the same engine (multimapping). The desired tuning can be selected while running, by a rotator or a dashboard switch, allowing the adaptation to the driving conditions, a super boost of the engine if necessary.

GENERAL OPERATION
The kit being based on the Meteor86 ECU, the overall functionality is the same (see standard kit description).
When Meteor86 is used in direct injection, injection is sequential, phased on the beginning of injection. The phase of the injections is controlled by 1/10 degree.

INJECTORS MANAGEMENT
The injectors command is configurable to adapt to the needs of the injectors to drive.
This command is composed of two main parts:
The peak delivers a high voltage under a strong current for a few hundred microseconds. This peak is a necessary part for a very rapid opening of the injectors. It is itself composed of two phases:
• The attack during which a high voltage (adjustable up to 65 volts) is applied continuously until getting a large current (can exceed 20 amperes)
• The withstand for which a switching of the high voltage is made to keep on the current level (adjustable length and switching).
The Hold, during which the voltage is supplied by the engine 12 volts battery supply with current control by switching the battery power to maintain the opening of the injector without damaging it by an excessive rise of its coil temperature (level of hold current adjustable from 1 to 16A).

FUEL HIGH PRESSURE COMMAND
The fuel high pressure pump control can be done in two ways:
In PWM by the fuel flow supplying the pump, the frequency and direction control are adjustable.
In engine synchrone command with tuning of the number of came push per engine cycle and push phases (to follow the camshaft drift).

Whatever the type of command used, the RCO of the command is managed by a PID to follow the pressure target.

FUEL PRESSURE TARGET
The base target is given by a map function of load and engine speed. It is then corrected to get a reactive adaptation to the conditions of engine operation:
• Dynamic correction of the fuel target pressure in acceleration (anticipation of the need for pressure)
• Programmable delay of fuel pressure drop while foot lift (avoidance of oscillations on cutoff-reacceleration)

PROGRAMMABLE EMPTYING OF INJECTORS RAILS
The fuel pressure is given by the balance achieved between the filling of the ramp by the pump and its emptying by the flow of the injectors.
At the cutoff during deceleration, the injectors being stopped, it is not possible to reduce the fuel pressure (if needed) by the normal operation, and the resumption of injection (including idling) can be at a pressure much higher than desired.
A programmable function of ramps injectors emptying during deceleration cutoff has been included in the management of fuel pressure.

METEOR86 ECU DIRECT INJECTION KITS

• The Meteor86 ECU is provided with accessories to install it on the direct injection engine.

 The USB connection-to-PC kit can be included in the ECU kit. It is essential to be able to connect your PC to the Challenger6 ECU and tune the engine.

*TWO LOOM TYPES ARE POSSIBLE

Semi finished loom
This loom is pre-wired on the ECU and driver side connectors, with sensors and actuators connectors not installed.
Its length is to be adapted when intalling on the vehicle, then the sensors and actuators connectors will be wired.
• The connectors of the standard sensors* and standard actuators* that are delivered with the kit are provided.
• The various branches of the loom are labeled (grounds, power supplies, measurements, auxiliary commands, injectors, ...) but not sheathed. High quality canvas adhesive tapes are provided to finish the sheathing when installing.

Finished loom
As every application is different, there is no standard finished loom:
You have to contact the Skynam technical service to detail the complete making of your loom (see contact page).
• The loom is completely sheathed with braid sleeving.
• The lengths of the various branches are standard (2 meters) or customized (lengths provided to Skynam).
• The connectors of the standard sensors* and standard actuators* are installed.
• The connectors of the other sensors and actuators are to install or are to provide to Skynam.
• The fuses and relays bases are installed if required.

*Standard sensors :
These are the sensors that belong to the engine accessories list.
• water and air temperature sensors,
• atmospheric and intake pressure sensors,
• temperature and pressure sensors of oil and fuel

*Standard actuators:
These are the actuators that belong to the engine accessories list.
• gazoline injectors,
• ignitions coils

 


CONNECTION KIT AND SOFTWARES
It is essential to be able to connect your PC to the Meteor86 ECUs and tune the engine. The USB-FTDI interface is the same one than for Challenger5, Challenger6 and Challenger7 ECUs.

FTDI CONNECTION KIT CONTENT
PC-ECU connection wire USB-FTDI
