Are all LS Coil plugs the same?
Please note that all the LS coils are interchangeable and can be used on any LS platform.
Do LS coil packs need to be grounded?
No, it must be grounded to the cylinder head that the coils are discharging to. Grounding to the frame is a bad idea. Doesn’t the harness actually ground to the head, and you just extend the harness to connect the coils? The valve covers on LS engines are insulated from the head by rubber gaskets.
What are the parts of a coil?
The ignition coil is always made up of three parts, the primary circuit, the secondary circuit, and the iron core. A magnetic field is created around the soft-iron core when an electric current flows through the primary circuit or winding.
Are LS1 and LS2 coil packs the same?
LS2 coils are advertised as being revised and improved in comparison to LS1 coils in that they are more efficient. They use less energy to provide just as much spark as the older LS1 coils.
What’s the difference between round and square ignition coils?
Round and square don’t literally mean you will see a coil that is completely round, but the round coil have a cylinder-like body to them, whereas the square coils have a boxy shape to them. The body of the square coils is nothing close to a cylinder shape.
What is an ignition coil assembly?
Coil-on-plug assemblies are designed to convert a low voltage (primary side) to a high voltage (secondary side) to fire the spark plugs. They perform the functions of both the ignition coil, which creates the spark energy, and the spark plug wire set, which delivers the high voltage energy to the spark plug.
What is the secondary ignition coil?
Ignition systems have two circuits that result in a spark being fired at the end of a spark plug. The primary circuit is between the battery and the ignition coil. The secondary circuit is between the ignition coil and the spark plug.
What does P0352 mean?
Ignition Coil B Primary/Secondary Circuit Malfunction
P0352 is a diagnostic trouble code (DTC) for “Ignition Coil B Primary/Secondary Circuit Malfunction”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
What is the part number for a LS2 ignition coil?
The part number for this ignition coil is GM 12570616 and 12611424 and it can also be found as an Isuzu part number 8125706160 or 8126114240 as well as Saab part numbers 12570616, 12611424 and 12611487. The LS2 ignition coil wiring pinout is comprised of basically 4 wires or pins.
What do you need to know about LS coils?
You will likely need to slightly tune much if not all of your fuel table. LS coils pack a meatier punch and will give you more complete combustion. The FlowForce LS coil harness comes wired for wasted spark for plug and play ease, and is also upgradeable for sequential ignition.
How do you install coils on flowforce LS2?
Let’s start with the mechanical installation of the bracket and coils. Remove the OEM coil packs (see the appropriate chassis year section for what to do with the connectors you remove). Install the LS2 coils onto the bracket with the supplied hardware – note that the latest version of the bracket comes with the coils pre-installed.
How do you mount a coil to a spark plug?
Connect the main harness to your coils. Mount the bracket to the intake side of your valve cover and then follow the torque specs and order in the service manual. The spark plug wires are 3 different lengths.
