MODERN CONTROL for your LT

Coil-per-plug ignition. LS PCM tuning. Factory harness compatibility.

Everything you need to future-proof your high performance racing LT1— without the hassle.

MEET THE 24X LINK CONVERSION SYSTEM

The factory LT1 Optispark system was innovative in the 90s. But today? It’s the weak link in your engine’s high performance racing potential. The 90's LT era PCM's are also widely unsupported. Getting proper hands on tuning can be difficult.

We have the solution.

FAQ

  • Do I need to modify my engine harness?

    No. The 24xLink LS PCM plugs directly into your stock or standalone LT1 engine harness (1994– 1997). No splicing, cutting, or rewiring required.

  • Will it work with my factory cluster and gauges?

    Yes. Your factory cluster and gauge functions are fully retained. Torqhead has even developed unique electronics that integrate the LCD screen functions on 1994-1996 Corvette dash.

  • Can I use my own tune?

    Yes. You can send us your base tune file (HPTuners format), and we’ll load it onto the PCM before shipping—free of charge. Need a custom tune? We offer that too for an additional fee.

  • What tools or skills do I need to install this?

    If you’re comfortable changing an optispark, changing sensors and mounting brackets, you can install this kit. Basic hand tools are all that’s needed—no fabrication required.

  • Is the LS PCM conversion emissions legal

    No. LS PCM conversions are not emissions legal. They are only to be installed on offroad or racing use vehicles. See product listings and our emissions compliance page for additional details.

  • Can I run this with an aftermarket ECU instead of the LS PCM?

    Yes. Choose the Signal Kit version if you're using a standalone ECU like Holley, FuelTech, or others. It outputs LS-style 24x/1x crank/cam signals.

  • Is there a warranty?

    Yes. All PCM and wiring components come with a 5-year replacement warranty. Signal kits are covered by 2 years and sensors/misc by 1 year. See warranty page for more details. If anything fails, we’ve got you covered.
