GAS ENGINE IGNITION MODULE

GT6 Ignition Module

Name: GT6 Ignition Module
Brand: Gill

A compact, cost-effective inductive ignition module for gas engines from 1 to 6 cylinders, up to 13 L.

GT6 suits rich-burn, lean-burn, naturally aspirated and turbocharged engines running natural gas, propane, LPG, landfill, digester and other biogas fuels. It takes its timing from a single inductive pickup and delivers up to 1,500 microseconds of continuous spark duration.

THE DIFFERENCE

What makes the GT6 different

GT6 is the compact entry point to the range. It is built for smaller engines up to 13 L and uses a single inductive pickup for timing. Where an engine has more cylinders, needs individual cylinder timing or load-based timing maps, GS8 and GS12 extend the same inductive ignition technology further.

BEFORE YOU SPECIFY

Is the GT6 the correct module?

Before specifying, confirm:

the number of cylinders, and that the engine is within 13 L
the spark duration the engine and coils need
how timing will be picked up: Gill timing disc, OEM cam disc, A5 kit or drilled flywheel
whether single global timing is enough, or the engine needs individual cylinder or load-based timing
the coils, SM 60 series or another Gill approved inductive coil
the 12 or 24 V DC supply available

If those match, the GT6 provides that configuration.

QUESTIONS

Frequently asked questions

What is the GT6 ignition module?

The GT6 is a compact inductive ignition module from Gill for gas engines with 1 to 6 cylinders and a displacement of up to 13 L (800 in³). It delivers 500 to 1,500 microseconds of continuous spark duration and is set up with free Windows-based software.

Which engines and fuels does the GT6 suit?

The GT6 suits rich-burn and lean-burn gas engines, naturally aspirated or turbocharged, up to 13 L. It is compatible with natural gas, propane, LPG, landfill gas, digester gas and other biogas fuels.

How does the GT6 take its timing input?

The GT6 uses a single inductive pickup. That can be the Gill timing disc and standard pickup, an existing OEM cam disc, an A5 conversion kit, or a drilled flywheel pattern for wasted spark firing.

What is the difference between the GT6 and the GS8?

The GT6 covers 1 to 6 cylinders with up to 1,500 microseconds of spark duration and global timing. The GS8 covers 1 to 8 cylinders, extends spark duration to 3,000 microseconds and adds individual cylinder timing, 2D or 3D timing maps, shutdown ground and fuel valve sequencing.
