## Overview

The GTC505 Engine Ignition Analyzer is a professional-grade handheld device designed to diagnose and measure all spark ignition systems. It delivers real-time secondary ignition waveforms, primary coil ramp time, dwell time, spark burn time, and RPM data. Featuring advanced charting and comparison tools, it excels at detecting intermittent faults and misfires across all spark-ignition engines, from small magneto 2-strokes to modern computer-controlled coil-on-plug setups. Trusted by ASE-certified mechanics and engineers alike, the GTC505 combines precision, versatility, and ease of use in a rugged 2-pound package.

## Description

The GTC505 Engine Ignition Analyzer is a handheld instrument designed from the ground up for the diagnosis and performance measurement of all types of spark ignition systems, from conventional to the newest Coil on Plug in use. The GTC505 is capable of displaying and measuring the following in real time: secondary ignition waveform, primary coil current ramp time, dwell time, spark burn time and RPM. It also provides two innovative and unique display formats used to compare measurements between cylinders, and to look at data for hundreds of spark events over time in order to detect intermittent problems, misfires and other performance issues which are very difficult to detect using conventional scopes.

Review: Great tool! Works very well great for quick detection of misfires easy to use! - I had this tool now for a while I'm impressed with it it works very well. It's great for a quick run and gun misfire chase down it's well worth the money. A great product from Canada! I'm sure this is a US seller support the US in Canada! The build quality is great the functionality is awesome! I think the price could be a little better but it's worth the money!
Review: A SPECTACULAR Tool - This is a SPECTACULAR tool. I have a oscilloscope I have used for ignition analysis for years and this little box does EVERYTHING I need and more. It beats out a very high end storage scope and gives clear, easy to understand info. I have been using my for over a year and could not be happier. This review is coming from an ASE Certified mechanic, motorcycle repair shop owner, retired 40 year career Electrical Engineer. PS - My first one, an early version, had a software problem. They took it back, found it, fixed it, and sent me a new fixed unit at no charge. How a company solves a problem is the true test of their customer service and technical expertise. These guys are GREAT.

## Questions & Answers

**Q: Is this top of line ?**
A: It's, as far as I know, a unique product. No-one else makes anything quite like it (as a handheld, one-box solution). I've got one, and it's a fantastic time-saver. I can do a quick look at four cylinder's worth of ignition waveforms in twenty seconds.
To do the same thing with my Snap-On Verus (five grand's worth) takes five minutes to boot, then a couple of minutes to find and plug up the adaptor, then another minute to configure the scope mode. And I gain little or nothing more by doing it with the Snap-On tool than using the GTC product.

**Q: Will this work on a single cylinder lawnmower engine to read rpm? If so what setting would you use?**
A: The problem is that when the unit is in tach mode it reads the wrong RPM’s because you you can not set it for the number of cylinders that your engine has. It’s permanently set for “8” cylinders with no way to change it to “1”, “2”, “4”, or “6” cylinders so that the tach function will read correctly. You have the option of setting the unit for a 2-cycle or a 4-cycle engine so why can you not set the number of cylinders?

**Q: Does this product have a warranty besides the 4yr protection plan?**
A: Yes, the GTC505 comes with General Technologies Corp's standard product warranty, which lasts 1 year (from date of purchase). Please visit the GTC warranty page for details https://gtc.ca/warranty.html

If you have problems after the warranty period, please contact the manufacturer, as GTC can often provide replacement parts, or repairs.

**Q: Can this be used to set ignition timing instead of a timing gun?**
A: Nope.  There is no strobe to illuminate the timing marks on the vibration damper.

### ⭐⭐⭐⭐⭐ Real-time visibility into coil performance
*by M***C on July 15, 2025*

I've been troubleshooting a problem with my wife's 2010 Navigator, which has had me poking at COPs for a while, now. When there's a misfire due to a failing COP, you don't need this tool to figure out which one -- the code that's thrown will tell you which cylinder. However, if the engine idles rough and there is no code for misfire (not yet?), or maybe you *think* you've fixed the problem and just want to be sure, having a tool like this within easy reach is extremely handy! Just point the probe over the top of the coil, and like magic, you're seeing spark voltage, waveform, and burn time instantly. Or... maybe you didn't fix anything and the engine is just magically running smoothly now? Use this tool to check the suspect coil's operational characteristics, then compare it to the other known-good coils to determine if what you're seeing is normal. Maybe the suspect coil is firing every time now, but the voltage is way low, or the waveform shows a wide, trashy waveform... now you know the problem didn't actually go away, it's just hiding (and you're not crazy). I've used this tool only a handful of times (same vehicle, same problem), but enough to confidently say that it works every time -- I just hold the probe over the top of the coil, and I get a clear, consistent reading. I don't have to fight with it, don't even have to worry about whether I'm holding my tongue right (haha), it just works. The unit itself feels solid and substantial, and there's nothing "cheap" about it. It's dead-simple to use, the display is clear and very easy to read, and I get the impression that the information is accurate and reliable. Even after it sat in its case for several months (since I last used it), when I went to use it again the other day, the battery was still fully charged and ready to go. The only downside is its price -- while every "shade tree" mechanic would benefit from having this in their toolbox, it is a bit cost-prohibitive. Given what it is and how it works, I can see why this isn't cheap. But if you're stuck on an ignition problem that you just can't figure out, or one that keeps recurring after you've fixed it, this might be worth the price to save yourself a ton of time (and your sanity).
