JPI enhancement request

[N601RX]

I had recently emailed JPI and asked them to consider adding a programmable restricted Yellow band on their tach display on their 730/830 series engine monitors.  On my model this would coincide with the 2100 to 2350 restricted rpm band.  The reply was "Sorry, not at this time".

 

I would like to encourage anyone who owns one of these products or plans to buy one to also e-mail them with the same request. Also for those going to Sun-In-Fun stop by their booth and ask in person.   If enough people ask they might add it.

That would be pretty easy to program for JPI..maybe 15 min of work...however that band should be yellow,not red as in it is a zone that is powered on thru and not a redline like 2700 is...k

Correct, I wasn't thinking.  I'll edit the original post.  As long as these units have been out, It's hard to believe someone else hasn't already ask for the change.

The 2100 to 2350 is red in my POH. On the EI tach I had installed, I have red bulbs in those zones.

As someone who has worked for the last 20 years in an FDA regulated software environment (similar to FAA) no code change takes 15 minutes. You have to update the requirements document, the trace matrix, write a test plan and then run a complete validation. Hundreds of man hours to implement a 15 minuet code change.

True. And for the primary certified gauge, this is probably correct. For those of us with the 730/830, though, they could probably add this relatively easily. After all, it seems like they change/update the software every month on that 830!

Some issues I've noted that were corrected by software fixes over the 3 years I've owned my 830...

Memory overload caused the unit to flash and reboot (fixed around the 3.17 timeframe).

Couldn't remember which button was which (fixed by adding labels to the software display with 3.25 or so... Genius!)

Most recently... RPM was "dropping" about 80-100 rpm for a split second every couple minutes, then going right back up to normal. This started happening after updating to 3.37. I updated to 3.39 and this glitch disappeared. Literally a month and a half between updates on that one (my guess is that I wasn't the only one with that RPM glitch, thus the update).

I really wish JPI would release a version history and tell us what's updated with their software updates... Then again, perhaps they don't want to air their dirty laundry IRT their software bugs. That memory overload bug had me chasing grounds, scratching my head, barking at the moon, etc etc.

Back to the original topic- I love the idea of being able to set a yellow band for the RPM. Here's to hoping JPI gets on board.

I agree completely. I updated to the newest version in December and when I looked 2 weeks ago I was 4 versions behind. Sometimes the changes are obvious, other times they are behind the scenes.

So, based on the last two posts, would you buy one again? The reason I ask is that I am considering an 830 to replace my old but still working like a champ Insight 602. It sound like the glitches at a minimum are annoyances.

Yes it works great. I would just perfer to know what the updates consist of and then make a informed decision as to if I want to perform the update or not. All it would take is a few release notes to accomplish this.

Yep. I like the display, and the ease of use. JPI has sorted out all the bugs now, it seems. Although I bet their will be another software update soon!!
