GTC505 Engine Ignition Analyzer

Finding dead or malfunctioning coils and plugs can be hard work. The GTC505 makes ignition troubleshooting quick, easy, and painless. It’ll help you, and the people depending on you, get moving again!

The GTC505 is the product of 20 years of work (by GTC) on ignition diagnostics. This tool will tell you exactly what’s going on with any spark ignition system as soon as you put its sensor by your coil (or spark plug wire). Swapping coils and other components in and out until you figure out what’s wrong is slow, tedious, and wasteful. The GTC505 will take the guesswork out, so you can be confident that the problem will be solved on your first try.

Who it’s For:

  • Automotive technicians doing diagnostics, tuning, or aftermarket modifications
  • Motorcycle technicians doing diagnostics or aftermarket modification on modern engines
  • Marine and small engine mechanics should take a look at the GTC505m kit.

What it Does:

Quickly and easily detects engine RPM and spark parameters. Useful for checking for ignition system faults and misfires, and for tuning or aftermarket modifications.

How it Works:

  1. Connect the appropriate sensor
  2. Turn the unit on
  3. Position the sensor near the ignition module or wire
  4. Check the engine RPM, spark peak voltage, burn time, and dwell angle/ramp time. The digital view gives you a quick look at the average, and the chart view will show you any misfires.

Warranty & Support:

Covered by our standard 1-year warranty, and supported for much longer. Replacement parts and accessories are generally available for 10+ years.

FAQ

What is the difference between the GTC505, the GTC505m, and the GTC505-CSC?

The GTC505 is an engine ignition analyzer. The most basic kit it comes in: with a flexible probe, extension cable, cop sensor, spw sensor, USB micro cable and AC charger adapter, user’s manual, 1 year warranty, and hard padded carrying case.

The GTC505m is an upgraded version of the GTC505 kit – it comes with everything in the GTC505 kit, but with the GTC505-CSC accessory, and a larger hard padded carrying case to accommodate the extra accessory.

The GTC505-CSC can be purchased separately (here), or together with the analyzer in the GCT505m kit.
