    From: FLYaDIVE <flyadive@gmail.com>
    Gary: This may help. I had the same problem on an RV6. When switching from Impulse Mag to Electro-Air CDI I was getting a backfire. I traced the problem to the Electro-Air vacuum box. The silver box where the MP/vacuum line connects to. The connection was broke inside the box and there was no vacuum advance. Fixed that and the problem has not reoccurred in the past two to three years.

    Cliff, Seeing your post reminds me to tell you I have an empty space in my hanger. I sold my Jabiru 250 last week..... Talked to Ruth and Brian a while back and they said you were not flying the Super Trainer much and it might need a new home.... Hurry before I buy a new car !

    Barry, I am the owner of 166. Right now, I am just skipping the right mag check which I consider to be no big deal, but I would like to make the situation better. Was the broken connection the vacuum connection inside the box or something electrical?

    Subject: Notes on installing the Electroair Ignition system
    First, I've always been a fan of electronic ignitions. =C2-I looked into DIS a LOOOOONG time ago(Remember the '87 Buick Grand National?). =C2-=0AS o, when the time came to install, not one, but two, DIS systems, I was anxi ous to get started. =C2-=0AEspecially since one was a Real Tiger and the other was an AG Tiger.=0A=0AHow long does it take: =C2-Realistically, 16- 20 hours.=0A=0AWhy? =C2-you ask? =C2-I spent at least 4 to 6 hours on e ach plane just looking for a place to put all the pieces and trial fitting everything before I drilled any holes.=0A=0A1) Magneto Timing Housing: =C2 -It replaces the right mag. =C2-That part was pretty easy.=0A=C2- =C2 - =C2-However . . . The lead (wire connection) on the MTH is about a mi le long (18 inches?) and I needed to find a place=C2-=0A=C2- =C2- =C2 -somewhere above the accumulation of oil and dirt to mount it. =C2-=0A =C2- =C2- =C2-Then, of course, the wiring harness from the Controller is really long for a Grumman and I wanted it=C2-=0A=C2- =C2- =C2-t o be where someone could R&R the MTH if necessary. =C2-So the connector h ad to be accessible.=0A=C2-=C2- =C2- =C2- =C2- =C2-Note: =C2- Best Case. =C2-It would be a whole lot better to have the connector right on the MTH housing. =C2-=0A=C2- =C2- =C2- =C2- =C2- =C2- =C2 - =C2- =C2- =C2- =C2-Worst Case. Limit length of the lead on the MTH to less than 6 inches.=0A=0A2) Coil: =C2-Where to put the coil? =C2 -Here, there is a difference between the two planes. =C2-=0A=C2- =C2 - =C2-AA5B: =C2-On the AA5B, the coil can go to the left of center on the firewall near the top. =C2-=0A=C2- =C2- =C2- =C2- =C2- =C2 - =C2- =C2- =C2- =C2-I put it so that the #1 and #3 coil towers s traddled the Carb heat cable.=0A=C2- =C2- =C2-AG5B: =C2-There are a lot of wires in the middle on the AG. =C2-=0A=C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2-I put the coil under the wires to ward the right side of the panel.=0A=0A=0A3) Controller: =C2-The installa tion of the controller and the MAP sensor are also different=0A=C2- =C2 - =C2-AA5B: =C2-On the AA5B, the controller can go above the copilots right peddle on the firewall near the top and just under the "U" channel. =0A=C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2-I u sed sheet metal screws into the firewall. =C2-The unit is light and the s crews worked great. =C2-=0A=C2- =C2- =C2-AG5B: =C2-There are a lo t of wires all over the back of the firewall on the AG. =C2-=0A=C2- =C2 - =C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2-There is literal ly no free space without moving something.=C2-=0A=0A=C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2-I moved the brake line on t he left of center just above the cabin heat box. =C2-=0A=C2- =C2- =C2 - =C2- =C2- =C2- =C2- =C2- =C2- =C2-I had to trim off the b ottom edge to keep the controller low enough to stay away from the controls .=0A=0A=0A3) MAP sensor: =C2-The installation of the controller and the M AP sensor are also different=0A=C2- =C2- =C2-AA5B: =C2-On the AA5B, the MAP sensor can go adjacent to the controller (to the inside) above the copilots right=C2-=0A=C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2-peddle on the firewall near the top and just under the "U" channel.=0A=C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2 - =C2-I used sheet metal screws into the firewall. =C2-The unit is li ght and the screws worked great. =C2-=0A=C2- =C2- =C2-AG5B: =C2-S ame problem here. =C2-Too many wires everywhere.=C2-=0A=C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2-I installed the MAP sensor=C2-about 6 inches=C2-to the right of the controller above the ca bin heat box. =C2-=0A=C2- =C2- =C2- =C2- =C2- =C2-=C2- =C2 - =C2- =C2- =C2- =C2-Note: =C2-The MAP sensor had a rubber hose coming out of it. =C2-=0A=C2- =C2- =C2- =C2- =C2- =C2- =C2 - =C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2-We ird if you ask me. =C2-A metal hose fitting would eliminate one potential leak.=0A=0A4) Harness: =C2-The harness is just a bunch of loose wires. =C2-There is nothing professional looking about it.=0A=C2- =C2- =C2 - =C2- =C2- =C2- =C2- =C2- =C2- =C2- On the AG, I was able to use 1/2 inch expando sleeve and get it over the VERY LARGE connectors. =0A=C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2- Ha ving the wires in a flexible sleeve help during the installation.=0A=C2- =C2- =C2- Note (1): =C2-The B+ lead from the coil goes from the coil to the 10 amp breaker. =C2-SO, it needs to be tied so it stays with the =0A=C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2- main harness on the inside of the plane. =C2-This B+ lead is about a foot too short so make plans ahead of time.=0A=0A=C2- =C2- =C2- No te (2): =C2-The P-Lead connection to the Magneto switch is also about a f oot too short. =C2-Make plans for it.=0A=0A=0A=C2- =C2- =C2- Note ( 3): =C2-The tach lead, as far as I can tell, is useless. =C2-They provi de a signal out but there is no signal processor to=C2-=0A=0A=C2- =C2 - =C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2- make it work with digital tachs.=0A=0A=C2- =C2- =C2- Note (4): =C2-There is a secondary lead on the harness section to the MAP sensor. =C2-SOOOO. =C2-You need to make sure the=C2-=0A=0A=C2- =C2- =C2- =C2- =C2 - =C2- =C2- =C2- =C2- =C2- =C2- MAP sensor is on airframe gro und.=0A=0A5) Installation instructions: =C2-First off: =C2-Substitute t he word "than" for the word "then." =C2-Don't know about you but . . . . =C2-Learn how to use the English language.=0A=C2- =C2- =C2- Note (1 ): =C2-There is a note that says "=A2 Built-in timing monitor" but I can't find where it is. =C2-Be more specific.=0A=0A=C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2-There really needs to be a way to monitor the timing for diagnostic purposes.=0A=0A=C2- =C2 - =C2- Note (2): =C2-They recommend NOT using a Breaker Switch for th e 2-amp circuit. =C2-They want you to install a separate switch. =C2-Th at makes no sense to me.=0A=0A=C2- =C2- =C2- =C2- =C2- =C2- =C2 - =C2- =C2- =C2- =C2-What makes sense: Install the switch on THEI R (not there) P-lead. =C2-More on this later.=0A=0A=C2- =C2- =C2- N ote (3): =C2-The instructions describe where to install another switch to turn the MAP on and off but the wiring diagram shows nothing about it.=0A =0A=C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2-Had this option been shown in the wiring diagram, maybe I would have noticed it. =C2-Reading through the text is boring.=0A=0A=C2- =C2- =C2- Note (4): =C2-Wiring diagram shows an LED line but it was marked " optional." =C2-I had to determine if the harness was really wired for it or not. =C2-It wasn't. =C2-=0A=0A=C2- =C2- =C2- =C2- =C2- =C2 - =C2- =C2- =C2- =C2- =C2-Good thing the wiring diagram shows t his to be an option. =C2-I'm being sarcastic. =C2-It doesn't.=0A=0A6) P lug wires: =C2-They are cut to fit. =C2-You'll need to install the nuts on the cut ends. =C2-=0A=C2- =C2- HOWEVER, the nut is so tight that it is almost impossible to get it on.=0A=C2- =C2- =C2- =C2-Note: =C2-=A2 Mark your desired final resting place for the nut about 2 i nches further up the plug wire than where you'll need it. =C2-=0A=C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2-=A2 Cram the s park plug lead in until you have about 1/4 inch sticking through=0A=C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2-=A2=C2-Grab hold of the part sticking through with a pair of Vice-Grips. =C2-=0A=0A =C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2-=A2=C2 -Pull like crazy. =C2-When you get to your mark, stop. =C2-Cut off th e damaged end. =C2-Assemble all the other parts.=0A=C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2- =C2-=A2=C2-This step takes abo ut 20 minutes per plug wire.=0A=0A=0A=C2- =C2- PLUS, the rubber seal lo oks like it was cut out by hand and the hole in the middle is NOT IN THE MI DDLE. =C2-Very badworkmanship.=0A=C2- =C2- =C2- =C2- =C2- =C2 - =C2- =C2-This makes the nut which you use to tightenthe wire onto t he plug VERY DIFFICULT TO TURN.=0A=0A=0A7) =C2-Initial run-up and testing on AG5B: =C2-I was anxious to see if it would even run. =C2-Electrical things can be so finicky. =C2-=0A=C2- =C2- =C2- =C2- =C2- =C2 -

I'd also like to try dual electronic systems to see if it still backfires. The hotter spark may light up all of the residual fuel. By-the-way, I had it leaned all the way. If it were mine, I'd skip the Right mag check.

    Ok Gary: The next thing I would check, if you haven't already is the timing for the pick-up that mounts on the accessory case/Mag hole. There were two service bulletins on them a while back: 1 - For breaking wires where they exit the timing gear (yellow wire) and 2 - The Hall Effect Transistor Now, I do realize these were OLD SB's and your unit is STC'd and going on GA aircraft. But, who knows! And another area of concern is the POOR quick-connect connection. I squeezed them so they would not move around.

    Gee John: Difficult question to answer. Maybe because some people are trying to bring our planes into the 20th Century. Hell with the 21st! Like everything with our planes; when they work they are GREAT! Better Spark Better HP Better Fuel Economy Better HP at Altitude Less Plug Fouling Fewer Moving Parts AND BRAGGING RIGHTS!

    Subject: Control wheel refurb
    From: "mbcrisp" <mbcrisp87@gmail.com>
    Does anyone have any suggestions on where to get control wheels refurbished? My control wheels are starting to peel and look pretty bad. I have seen several options such as leather covers but wondered if anyone has found a solution that really looks good. Also, has anyone ever replaced the lower plastic panel where the the rocker switches and throttle are located? How labor intensive is it to replace? Mine is beginning to look really bad and has several cracks. Read this topic online here: http://forums.matronics.com/viewtopic.php?p=371000#371000

    I have "refurbished" a lot of yokes. In the process, I drill them for built in PTT. They look very professional. AND . . . No visible wires. It's time consuming and expensive. Figure about $320 delivered. I strip them, sand blast them, have them chem-film plated, drilled, powder coated, and wired with PTT buttons and shielded 2-wire twisted pair. I've powder coated with gloss black, satin black, black wrinkle, black and gold hammertone, black and silver hammertone, and dark gray wrinkle. I've also had the yoke shaft powder coated with satin black. The black yoke shaft looks really cool with the powder coated yokes.
