That sucks if you have larger injectors because that throws the mass fuel stuff right out the window. I'd hate to risk my engine relying on a calculation when it's cheap to buy an actual sensor that will tell me exactly how high my exhaust gas temperature is.
In addition (and hate me all you want for saying this, but it's my opinion and we all have one), the layperson should not have access to tests that they don't understand. I'm not targeting you, but for 99% of the people out there who buy diagnostic equipment just to run "buzz tests" and "contribution tests" without knowing what they're looking at/for, only leads to lots of frustration of changing out #3 and #8 injector repeatedly because they always come up bad. That's small beans compared to throwing in a new set of injectors because a certain cylinder came up in the contribution test....only to find out after thousands of dollars that the cylinder in question simply had a broken rocker arm.
It also amazes me how much bad information comes out of having the ability to do a "buzz test". Easy example: White smoke due to unburned fuel with a rough idle CANNOT be diagnosed with a buzz test. Besides, those symptoms CANNOT be caused by an open or shorted electrical connection between the IDM and the injector. People will have other folks chase their tails for DAYS suggesting a "buzz test" for a concern like this. "Oh, check your valve cover harness".....no, that will not help you locate your problem in that case.
Now that I'm done venting, HATE ON!!!!!!

No hatin here Cody. I understand what you're saying about "estimated" EGTs...I felt the same way about it. BUT, if you do read more into it you will see that the gauge has an optional Aux. port where you can plug in an actual EGT probe... IIRC. And I understand about people doing the self tests.... kinda an iffy subject I guess. It's handy to have for those who know how to use it. But for some, it can confuse them worse.
