User Manual – Haltech 350Z
7.3 Copy through Feature
The copy through feature allows the Haltech ECU to output the factory ECU’s fuel and ignition timing values,
wherever the user specifies. This feature allows mildly modified engines to retain the factory operation without
having to tune the entire ECU.
Copy through can be enabled in the Base Fuel & Base Ignition tables by pressing ā€œCā€ in the desired cells.
Multiple cells can also be selected and set to Copy through.
Please note, that when the engine is operating in Copy through mode, all corrections will be ignored.
