    [attachmentid=564]Hi all, I hope you can help me,

    I have this circuit, It is used to manipulate engine ecu, I have identified most of the components but need help in identifying others,

    The objective of the unit is to reduce or increase the actual signal coming from the vehichle sensor, then interpreting it and sending the signal on to the ecu.

    The 8 din optocoupler i need to know the number of it if any one can help me.

    would you please explain if i have got the right numbers and descriptions for the other components.

    I appreciate any of your help.

    Thanks,
