LT1 to LS1 Swap - Ignition Fuse Hi,
I'm doing something somewhat confusing. I had been running MegaSquirt on the LT1, using the factory harness. The megasquirt was installed inside of the original ECU housing.
Now, I am swapping an LS motor into the car. I have modified the harness and ECU for the additional ignition outputs and crank/cam sensor.
My question is this:
The LT1 ignition coil was powered thru under hood Fuse #11. This is a 10a fuse which also powers the auto transmission.
My original plan was to use the LT1 ignition coil power wire to run to the LS coils, but...
In looking at schematics for the LS1, each bank of 4 ignition coils was powered by a separate 15a fuse.
Since it is sequential, I figure the wiring should probably be fine since only 1 coil will be firing at a time.
How did other people manage the ignition fuse/wiring when they swapped from Lt1 to Ls1?
