I was just wondering what the meaning of the "warnings: 0" under my name was...Coudl somebody explain it to me... Thank you

Let me support the previous suggestion.. great idea and I vot for Craig's panel too.

Same with me too. I just added and ASPEN to my panel and decided to keep the MPH. Just simpler.

Just to bring the story to a closure, JPI was not properly grounded. Now, the indications are normal, CHT 1, 2 and 4 in the lower 300 and 3 still hot, but not too hot.

I had a similar problem with my M20C. Since I have the LASAR ignition, she starts up without any problems. Mix rich, Fuel pump on, pump throttle twice (depending on the temperature) and she fires up

I love it! Congratulations and thanks!!!!

No filters on mine... a M 20 C. but also, never had a problem with bugs...

If you upgrade to a JPI 830 just make sure that you have CHT K probes and not J Probes. But great work, very nice panel

Just to provide you with an update. I checked the probes and they are K type... So no problem there. I also checked the connections and I tested the one probe and everything is OK. Then I asked my AP to have a look again at the connections for the LASAR ignition. No problem there... So I decided to start the engine and just see what was going on. I ran the engine for about 30 minutes on the ground (about 85 degrees and 5000 feet field elevation). One CHT (number 2) got up to 450... the rest behaved well around 390 to 423 (considering LASAR and temperature). Talking to some people on the field I was told that LASAR was a problem around here (high temps and thus high density altitude), because it raises the CHT... I was also told that several owners just went back to magnetos because of that... So, thanks for all the inputs...

Dear taracka Thanks for your comments. My mooney is a M20c. The engine a o360 a1d With a LASAR ignition. The engine has about 17 hours since major overhaul. Fuel is ok, timing was fine until until I flew her last time, the mechanic checked the baffling and it was fine too. Temperature was in the 80 and density altitude about 5000 feet. The jpi was installed in 1990. Could it have been installed with gem probes? How can I find it out?

Unfortunately the factory cht isninop. But good to hear that somebody else heard about this

Well here I am again with a question, that hopefully somebody will be able to help me find an answer to. I just updgraded from a JPI 700 to and JPI 830. I used the old EGT and CHT probes. Until I upgraded my CHT indications on the 700 were basically normal. Around 380 to 400 (I have a LASAR ignition system which raises CHT by 30 degrees). After I upgraded, I started the engine and CHTs inmediatly went through the roof. On all 4 cylinders they reached 400 in less than 20 minutes and after take off they reached 500! Which of course made me land right away. But as I mentioned before...everything was normal until the upgrade... Also, oil temp, oil pressure and EGT are in the green...I asked my mechanic to look into the baffling and the doghouse and he confirmed that everything looked OK. Unfortuntaley I was not able to check if the probes were working well... So, I decided to call JPI and they told me that I may have some old GEM CHT probes with and a GEM harness which is not compatible with the 830... My engine has only 17 hours since MOH...and I am flying out of a field with 5000 feet elevation... Does it make sense what JPI is telling me or should I looked at something else...

Thanks all those comments are extremely helpful. I have been flying more and more from grass fields and the mooneys are not that bad, as long as you follow the procedures.

I open it rather often. Just to check that everything is OK

Yes, better leave it as it is. I had to park my mooney for four years and I was recomended to just put it on some blocks, pickle the engine and leave it covered. March I brought her back to life...no mayor issue.

Really interesting. Obviously they are working on reducing the time lag.

As Mitch mentioned, it is labor intensive, but really worth while.

Steve, excelent job! I wish you both a quick recovery. Once again, this only shows how little our media knows about flying and how important it is for us to be able to educate and show them what we are doing.

I tossed it out during my panel upgrade. Now I have 2 430 and a portable 795, plus the ASPEN. The problem is the cost of the database (s).

Very nice... congratulations. Looking forward to having it up and running.

Great idea

I just send it to you, please let me know if you got it. Oscar

Hi there, Welcome to the list! There is a Training Manual prepared by MAPA that gives you tons of tips on how to use your M20C in IFR, speeds, power settings, etc. I am sending it to you by email. Enjoy your training and follow Byron's advice...:=) Oscar

Byron, Fair enough. Oscar

Byron, excellent points. However, what do you do while your original gauges don't work... I had an AP that did not want to sign off my annual because the original CHT gauge was INOP (although I had a JPI 700). I went to another AP and he did not even mentioned that the gauge was not working. However, this time around, I decided that I would like to be fully legal...
