G Series - Pilot Feedback
App. 2 weeks ago I have called you to get an idea why one of my 2 G3’s ignores all inputs coming from P2.
I expected to hear that this cannot be or that I made a mistake when I spliced the connector, etc…
You brought in your engineer who explained how to open the instrument and that there could be a bad connection between 2 PCBs.
This was exactly the issue. I just had to connect the boards and fit in the white plastic spacer. After re-fitting the instrument in the panel, it worked perfectly.
Thanks for your serious attitude towards your customers!
Thanks and best regards
Subject: feedback on G1
Yes please do post.
The more I use them the more I like them, excellent product.
This is one area where you guys are lacking. I was surprised that I could find precious little comment on the G series before purchasing.
I purchased based on study and my experience with my 610's.
I think if you had a web page dedicated to customer feedback it would be a great sales tool. I have to believe that the vast majority of your customers will have very positive comments.
I say vast majority because as you know there will be the occasional bone head that will be unhappy no matter what you do.
So you have to accept the bad with the good.
Just my 2 cents.
Thanks again, best regards,
Well its like anything else it takes a while to get the hang of it. These are really great instruments!
What I have found is that with the increased precision, you really do need to have tuned injectors. No my situation worked out really well: I found a dirty injector on #4 on the left. Getting that cleaned up & moving a couple other injectors got me to within .4gph on the GAMI test.
On the right side after "musical injectors" I was able to get #1-4 all identical, with 5 & 6 peaking way too late (too rich). Those two have been sent to a shop that does a flow analysis & can lean them out to get them to peak with the others.
So next week when I'm all done I'll have each engine with matched fuel flow/peak egt. When pulling back the mixture I'll get all 6 peak boxes nearly simultaneously.
Of course the other way to do that is to spend another $800 per engine for GAMI injectors, but my case worked out unusually well and that was not necessary.
Thanks for your help. It was very interesting, and at the end I'll have much happier motors.
Got it installed, and man do I love it.....noticed right off the bat my #2 cylinder was running slightly cooler on the egt's and discovered a minor intake leak.
The egt's are so quick to respond I even found what spark plugs were less than perfect during the run-up.....thoroughly impressed so far.
Install was pretty easy and straightforward.

G3 vibration case study.
Question: Why would I want vibration analysis on an engine monitor?
"I had used the Excel vibration graphing tool on Insight’s website to print out the vibration analysis data from my G3 over a couple of flights for a baseline benchmark.
the G3 for 8 months I also had a new 3
bladed prop installed on my Trinidad
Socata TB20 with a Lycoming IO 540.
with a Lycoming IO 540.
After 90 hours I noticed grease, and had to have the prop pulled and resealed. I was told that the reseal would be covered under warranty but that I did not need the prop balanced again.
It felt rougher to me, however, so I printed out another vibration analysis which confirmed more vibration after the re-seal than before".
I am having my prop rebalanced this morning and will send you a new "after balance" chart as well as a couple more "before re-balance" charts later today. The shop tells me when they balance, they are correcting the vibration in the vertical axis only. I told them the Insight sensor measures in all 3 axis. Do you know if it is the X, Y or Z axis that correlates to the vertical that they are correcting?
The Vertical axis is the Z Axis on our sensor. The Left-Right lateral axis is Y.
Because the prop spins in a plane defined by YZ, prop imbalance will contribute equally to Y and Z. X is Fore-Aft, and in theory would be relatively unaffected. Note that this definition depends on your sensor being mounted in the same orientation as the pictorial airplane on the sensor itself. If you've mounted it in some other orientation, you will have to translate it accordingly.
We look forward to examining the vibration spectrums.
Vibration data of new balanced prop (showing some imbalance)
Vibration data of rebalanced prop (a lot smoother as you can see; better than new)
I owe this
"warranty" prop balance to the evidence
supplied by my G3 prior to and after the
A new balance was approved under warranty.
Answer: A G3 color graphic engine monitor is one of the few things you can put in your aircraft that will actually pay for itself.

G3 Pilot Feedback
I recently upgraded my Baron B55 from a GEM 1200 to two new Insight G3 2.25" instruments. These color engine gauges take engine management to a new level at a very affordable cost. The upgrade used my existing probes and wiring for the EGT and CHT sensors and reduced the time and cost of the installation dramatically. I can now see the temperature of every EGT and CHT simultaneously in addition to the color coded bar charts on a crystal clear LCD screen. The lean boxes that show the current EGT variance from peak EGT make the leaning process very simple and easy to monitor throughout the flight. On top of that I get backup instruments for all other key engine data to provide redundancy to my unreliable legacy engine gauges. The Insight G3 instruments make flying my plane even more fun and safer than ever.

"During my first flight with the G3, I very quickly learned the value of the probe diagnostic functionality. It turned out that this flight was also the first flight with 6 new cylinders on my Cessna P210 so it was intended to be a 2 hour, high power break-in flight On the ground, during run-up, all my EGTs and CHTs looked normal. However, 15 minutes into the flight, the #3 EGT began to show odd and fluctuating temperatures. I was flying with my mechanic and we both believed that we had a probe issue but decided to head back to the airport and land just in case it was something in the new cylinder. Given our newness to the G3, neither of us thought to look at the probe diagnostics page until we were actually on final. Once it dawned on us that the G3 could tell us if we had a probe failure or not, a quick glance at the probe diagnostic page showed the #3 EGT probe at around 90 ohms resistance, an obvious failure. The G3 made it very easy to spot as the data for that probe was displayed in red. Now that we were confident that we had a probe issue and not a cylinder issue, we continued the flight, saving a complete cool-down cycle on the new top end as well as the time to un-cowl and diagnose the #3 EGT probe.
Interestingly, back on the ground after the flight, the #3 EGT probe again showed 5 ohms. Clearly this probe was only malfunctioning at high temperatures, making it very difficult to diagnose on the ground. Insight has really touted this feature and I have now had the real-world experience to understand exactly why. Great job, Insight!"
All the best,
I wanted to tell you all that I have flown with the new G-1, which I only have two flights thus far, but it's worked perfectly.
I totally love it. It such a nice upgrade from the 602 unit I've used for so many years.
I was worried being an older guy that I wouldn't be able to read the CHT and EGT numbers because they are kind of small but the display is so good that it's not a problem.
Also the color status on the bars makes for an easy quick scan and having constant EGT & CHT's for each cylinder displayed all the time is really slick.
I now have a much better idea just what's going on in each cylinder then I ever had prior.
The top box showing the temp diff. Lean or Rich of peak is also really cool and provides a great reference for adjusting the mixture. A really nice job with it and in the end it was well worth the wait.
