Vems Ecu Wiring Diagram. It shows the components of the circuit as simplified shapes and the talent and signal connections amongst the devices. Cable will cause a significant voltage drop during cranking that will cause the ECU to reset when the battery starts to run low.
The output from the HEF4024BT chip is routed thru an 1kohm resistor and with the internal pull-up in the VEMS are the output voltage square between 15v and 5v and this is too high. Once you have connected and checked the continuity of ground you can connect your VEMS unit to the EC36 plug and apply the power supply. This may prevent the car from starting even if the engine cranks over.
VEMS features an advanced injector control system which can control high impedence injectors with incredible precision.

Our standalone ECU has been developed by motorsports enthusiasts to provide other enthusiasts with a complete system with features only found in the more expensive high end engine management systems. Once you have connected and checked the continuity of ground you can connect your VEMS unit to the EC36 plug and apply the power supply. Im using Vems v38B hardware where there are pull up resistors for both wheelspeed channels mounted on the board.
