Ignition coil with IGBT
The EFIgnition has no built-in ignition output stages (IGBT).
The underlying reason is that these end stages can break due to incorrect control, incorrect connection, a defect in the ignition coil and old age.
Nowadays there are very many ignition coils available which already have a built-in IGBT.
The EFIgniton sends a 12V pulse via a transistor (FET). This transistor is controlled by the processor. The current is limited so that the print path of the ECU does not immediately melt in the event of a short circuit. The maximum current is 60mA at 14V.
- At least 2 ignition coils can be connected to 1 channel
- A total of 6 channels are available
- A V12 engine with a double spark plug per cylinder is no problem for the EFIgnition (24 coils!)
