Dual P-MAG Reliability in 2017
Hello all,
So the RV-8 I just purchased has the LASAR ignition system, and unfortunately the slick mags it uses are just about to the point where they need to be overhauled. Instead of paying to overhaul the one off mags, I?m debating replacing the LASAR system. I?ve priced out 3 options. 2 Slick Mags - $2500 2 P-MAG?s - $3200 G3I Ignition - $4600 The airplane currently has an auxiliary battery, but I like an ignition that isn?t reliant on ships power, so those are my 3 options. I like the idea of the P-MAG?s the best, but have been unable to on find any data on reliability of the new, v40 firmware, latest version of the hardware P-MAG?s. I also think the P-MAG would be the most straightforward install given the LASAR setup I would be removing already has a Manifold Pressure Line etc. What are your thoughts? |
RV-8A with 700 hours on a dual pMag install. Performace has been flawless.

We went through this same thing here a couple of weeks ago. As usual, a long thread.... search for Pmag.

I had two PMAGs in my RV7A and I was running v40 which ran flawlessly for the 150 hours that I had installed the PMAGs. The installation and timing of PMAG is super easy. I saw about a gallon of fuel saving (for the same speed) up high and about .8 of a gallon of saving when I had only one PMAG.
I definitely recommend it. |

Been running dual p-mags since first flight in 2008, flawless performance, would definately do the same again.

Like any thing else, a few units will suffer infant mortality, but for the most part, they are bullet proof.
Just make sure to install them per the manual. Depending on the engine you are running, you may have to tune them to match the manufacturer's recommended timing. This is fairly easy to do. Check your email. |

The control panel is hideous and I don't want it on my panel. If it could be integrated into a panel that looked more like something that belonged in an airplane I would be more interested. The airplane currently has a really neat, well laid out steam gauge IFR panel, and I don't want to ruin that with the incredible hulk of engine monitors. |
Indeed the current gen CPI brains are "unsightly", but there is no need to have them in the panel. They can be hidden once programmed.
