JPI recently stated on a Comparison Chart posted on its website that the chart was created . . . "to counter numerous intentionally false claims being made by our competition." We are offended by such a misleading and malicious attack on our integrity (JPI could only have meant Electronics International and/or Insight Corporation, since ours were the only two "competitors" listed). We are as dedicated to running our business with honesty and decency as we are to providing some of the highest quality instruments possible in general aviation,

We have contacted JPI many times over a course of several years, requesting them to be more accurate and less misleading in its statements, graphs and demonstrations regarding our products. There has been little or no success in those attempts. The one time a JPI modification was brought to our attention, we upgraded our information immediately to maintain accuracy. We are so committed to operating our business with honesty that nothing JPI could have said or done would have made us more indignant than its deceptive statement on its Comparison Chart. We hope our commitment to operating our business with honor and honesty and our twenty-year reputation in general aviation as a company of integrity and caring will speak for itself to our potential customers.

It is sometimes difficult and often confusing for us to understand JPI’s instrument claims (e.g., a recent JPI website Comparison Chart claims 43 alarms for its EDM, yet JPI’s Manual lists only 10 alarms), we have therefore produced the following Comparison Chart by taking information and claims only from each company’s instrument manuals.

Comparison of Products

Features/Functions

E.I. UBG-16 Ultimate Bar Graph Engine Analyzer

JPI EDM 700/800
Price

 

 

 $1,962.00 Retail price w/ 6 EGTs, 6 CHTs and 1 TIT

$2,416.00 Retail price w/ 6 EGTs, 6 CHTs, 1 TIT, OAT and Fuel Flow

 $2,360.00 Retail price w/ 6 EGTs, 6 CHTs and 1 TIT (JPI's EDM 700)

$4,155.00 Retail price w/ 6 EGTs, 6 CHTs and 1 TIT (JPI's EDM 800)
Case size 6" (6.25" including bendable wires at back of case) 7.25" (9.1" including rigid connectors at back of case)
Stable one degree resolution Yes. May need to be set from 1° to 10° resolution to eliminate jumpy readings, according to JPI’s manual.
Segments per column 21 20
Normalized Mode with Long-Term Memory for detecting trends and evolving problems Yes.    Compares current engine performance for each cylinder with engine performance during previous flights. No.    Normalized mode only compares temperatures from the moment you entered the Normalized mode. Once you exit that mode, the information is lost.
True Peak Detection Yes.     The UBG-16 will automatically return to the "LEAN" mode as you continue to lean if a false peak is detected. No.    The JPI's EDM locks onto the first temperature drop, which could be a false peak.
Independent Resolution for the EGT Columns (the finer the segment resolution, the more accurate the information). Yes.    EGT columns can be scaled to any temperature range to accommodate any engine, (For example, if the top segment is set for 1650 degrees F. and the bottom segment is set for 1250 degrees F., the segment resolution will be +/- 20 degrees F.) No.    The resolution is dependent on the high TIT limit. The bottom segment is factory set to 50% of the top segment. (For example, if the high TIT limit is 1650 degrees F, then the bottom segment will be 825 degrees F, which makes the segment resolution +/- 43 degrees F per bar.)
Number of Pilot-Programmable Alarms:

EGT overtemp alarms


 

EGT low temperature alarms


EGT differential alarm

CHT overtemp alarms


CHT low temperature alarms


TIT overtemp alarm

TIT low temperature alarm

Automatically calculates and digitally displays the temperature below peak EGT for each cylinder Yes No
Automatically aids in Leaning on the Rich Side and the Lean Side of Peak Yes.  Using the UBG-16 for Lean of Peak Operation & Using the UBG-16 for Rich of Peak Operation No.    JPI's EDM automatically defaults to leaning on the rich side of peak.
Scan Mode Yes.     Enters in Scan Mode on request and stops on request or alarm. Yes.     JPI's EDM will enter scan mode whether you ask for it or not.
Stores Last Peak Reading and Channel in Long-Term Memory Yes.     The cylinder that peaked first and the peak temperature can be viewed at any time. No
All programming done from the front panel Yes Yes

Data Recording

 

 

 

 

 Yes, up to 690 hours by adding EI’s Black Box Data Recorder ($395.00 retail). Also, GPS and data from six other instruments can be recorded at the same time. The Black Box Data Recorder can be purchased when purchasing the UBG-16 or can be added at a later date, without returning the instrument to the factory.

UBG-16 Packages now Include Memory (MUX-8A)

 Yes
