Visit Preferences to set your user name Summary of change: '''Safe Fusing Of The ECU''' Constructing a custom loom to match application perfectly. '''Injector''' output power circuit in this application will be fused at 5 amps. Fuse best placed to protect FET's rated at ~7amps continuous. I have calculated the 'worst case scenario' loading for the injector outputs should they all be 'ON' (unlikely) using the coil resistance of the solenoids and injectors. *4x injectors at 14ohm *1x boost solenoid at 27ohm *1x Emissions purge solenoid at 24ohm **The resulting parallel circuit resistance is 2.77ohm **The resulting current draw in worst case is 14.5/2.77=5.3 amps '''Ignition''' 10amps (if not less?) appropriate for 4x COP's? *The Toyota Yaris coils are often used to upgrade a wasted spark coil pack on the Mitsubishi Evo's and they use the original coil wiring which is fused at 10amps. *Not having probed the coils, 10amps seems reasonable since that is what I used previously with wasted spark coil pack and Desno inductive COP's. '''WBO2''' heater circuit suggested fuse rating of 5amps. ---- Return to MembersPage/Sprocket Optional: Add document to category: Wiki formatting: * is Bullet list ** Bullet list subentry ...
