Haltech Melted Ignition Coils
Hello Everyone,
I recently made the swap from a PowerFC to a Haltech Elite with patch harness. Everything went smooth while the tuner and I threw it in until about 10 minutes with the key on accessory then the coil packs started smoking. I am running SBG IGN-1a coils and both trailing coil packs were so hot they started to melt. No idea what the issue was but the patch harness checked out and he said dwell time was already set up. I believe it was an identical setup to another haltech install he did besides changing for the coil packs I am running. To my surprise the car runs pretty good and coil packs are a normal temp but still slightly warmer than the leading coil packs.
Any clue what the issue could be? I am afraid this will happen again on my replacement coils but I doubt it considering they are no longer getting hot.
Thanks

Are the coils wired for and intended to run in wasted spark or direct fire? Having an aftermarket direct fire setup and using the haltech basemap that is configured for wasted spark outputs can definitely cause you to be sending a full solid signal output to the coil causing it to see full time charge current instead of your dwell time, which can cause them to get extremely hot and die.
Should this be the case, you may want to reconsider your tuner as this is pretty common FD tuning general knowledge...

Hey Skeese,
Thanks for taking a look. The coils are still wired up as wasted spark. I decided to throw in the new coils yesterday and take the car for a ride. They didn't melt and weren't warm to the touch like previously. I'm thinking maybe while he was changing the configuration of the map with the key in the acc position that he didnt get to the right settings in time which caused the melting? Maybe the map he had was for direct fire and didn't realize at first
either way I'm just happy I haven't melted the new coilpacks yet
