ECU Wiring Diagrams The wiring for the different ecu levels are very similar with all the power output and input pins staying the same. The differences are with the extra features added to the later cars for things like closed loop lambda control, knock sensing and air conditioning. Level 1 ecu The level 1 ecu uses pin 12 as an output to drive a engine management fault light via a relay. The MAP sensor wires are fully screened back to the ecu to prevent electrical noise affecting the mixture.

Level 6 ecu The level 6 ecu is wired the same as the level 1 ecu except the engine management fault light is no longer implemented. ECU Wiring Diagrams The wiring for the different ecu levels are very similar with all the power output and input pins staying the same.

I don't understand what's happening. Thanks to your help. I tried to look on which cylinder the car turned and I think that it is random because by disconnecting injectors 1 by1it continues to turn on a dough by feeling the gasoline.

The ecu itself also contains a diode so it doesn't matter if the ISCV doesn't have one built in. All sierra cosworth models used a loom which was separate from the car loom, so it is easy to remove it and use in a different application.

I know that with L6 and L8 on Sierra Cosworth, these operations were realized with no problem at escot. It has the ISCV power feed moved to the ecu relay rather than the fuel pump relay probably in readiness for the P8 ecu which uses a self cleaning software routine which will pulse the valve fully open for a few seconds before the engine is started.

But during the test of starting up, it is similar. The differences are with the extra features added to the later cars for things like closed loop lambda control, knock sensing and air conditioning. Level 1 ecu The level 1 ecu uses pin 12 as an output to drive a engine management fault light via a relay.

The ISCV may have a picture of a diode on it like the one shown above. Actual fault codes are still available from the test connector obviously.

The MAP sensor wires are fully screened back to the ecu to prevent electrical fscort affecting the mixture. The 4x4 L8 differs from the earlier ones in that it is a two part loom with an engine section and a scuttle to ecu section allowing the engine to be removed with its loom still attached.

As if sparks in the ignition were missing.
