Frequently Asked Questions
Will this coil work with my stock Harley ECU?
Yes. The ION Sense feedback is engineered for direct compatibility with stock 1995-1998 Harley EFI computers without tuning or modifications.
How much does spark voltage increase compared to stock?
Peak spark voltage typically increases by 20% or more over original equipment, resulting in faster ignition and hotter flame kernel.
Does this fix my high-speed misfire?
Yes — the increased spark output stops high-speed misfire caused by weak ignition at higher RPM and load.
Can I use this if I run both Dual Fire and Single Fire applications?
Yes. This coil supports both Dual Fire (two cylinders per coil) and Single Fire (one cylinder per coil) configurations.
Will this improve my gas mileage?
Many riders report improved fuel mileage and throttle response due to more complete combustion from the hotter spark.
