You're certainly on the right track to want to monitor all 6 cylinders!  I also have a Jab 3300 and I initially had a GRT 6000 and it probably is the best bang for the buck.  However, it began to look dated once I installed a MGL XTreme mini-EFIS so I also got the MGL XTreme EMS for engine instrumentation.  To me, the graphical display of the MGL EMS is much easier to interpret than the alpha-numeric data from the 6000.  I don't know if the latest model is any different, but my 6000 did have a sort of dot-matrix graphic display for EGT and CHT, but it was so small and difficult to read that I never looked at.

Original panel:

XTreme EMS:

Present Panel:

Of course, the XTreme mini-EFIS is capable of displaying both flight and engine instrumentation, but that's an awful lot of data for the small screen of the mini-EFIS but if you went that route, it's probably the best bang for the buck if you need the flight instrumentation, too, plus it has a built-in GPS navigator.

There's nothing wrong with the GRT 6000, however, if you're on a tight budget.  But whatever you do, get 6 probe EGT/CHT capability!

Hi john, I decided to go with the mgl extreme ems for now. The EFIS looks good for the money as well, but like you say that’s to much info for one small screen. I have a six pack so flight instrumentation is good for now. I have been keeping up with your past and present posts on the jab 3300. I like the small ring cht probes you have mounted on the cylinder head instead of the spark plug ring. I want to do that. My question is this, should I purchase the actual 12 mm rings and cut them down and drill, or have you found a better probe.? Let me know. I also friended you. Thanks Jeff Herman ,pa

Jeff,

I just cut down my plug ring probes and drilled them since I already had them and they work great.  If you have to buy all the probes anyway, it would of course be nice to get some with a small ring so they wouldn't have to be modified.

You might talk to Matt at MGL support to see if there is a recommended probe with a small ring for mounting directly to the cylinder head.

Have you looked at the JPI EDM-350?
