Each to their own.

Using the EICommander i'm running a negative 1.4 on the A curve which has been working nicely with Dual P-Mags. Nice to have the instrumentation and control over them.

How can we find out which firmware version we have and I assume updating it will require it to be sent back to the factory, correct?

Dual P-mags.... Get an EI Commander! You would be surprised what it will show you.

Not sure I am buying that.
I thought the timing mark on the Emagair units was a number that is compared to the count of a randomly installed rotary encoder. We have seen uncommanded timing changes on early emagair units reported here. Giving emagair its due, it has been stated that those failure modes have been addressed and it has been a long time since any have been noted. However, it is not clear to me how this "count number" is hardened against all electromagnetic intrusion including cosmic ray degradation. I don't like inability to set these mechanically (as I was told by Brad) to eliminate the reliance on the puff number.

There are four ways:
1) Write your own code to connect to the P-mags and trigger the streaming data.
2) Install an EICommander and have it tell you what version you are running.
3) Connect to them with the EICAD program and have it tell you.
4) Look at the sticker on the body of the P-mag and the version number should be written on there.
Version 40 just came out on 9/26/2014, so if your P-mag is older than that or hasn't been back for an upgrade, chances are you are not running Version 40.

Awesome and thanks for the info. Now, would I need to send it back for the firmware update or can it be done with EICommander?

No, we have discussed allowing the EIC to push updates to the P-mags and we both agree that we don't want to do it. It is best for your safety to send the ignition back to the manufacture for the update.

Hello Bill and other guys
my question:
should be compatible one Pmag firmware 36 (mine bought one and half years ago) with a new one with firmware 40?
How can I set both at the same retard BTDC?
Or I need/must upgrade the older one? (@#!"&=§% shipping back in US from Italy)
Thanks in advance for you suggestion
LC

While you can always send the older one in for the update, it really isn't necessary, unless you have a lightweight prop. If you have a metal prop, I would set both P-mags the same.
At your next condition inspection I would send the older one in for the update, just to make sure they are the same.
Clocking your older P-mag a few degrees means they won't fire at the same time and you lose any advantage of having identical ignitions.

Bill,
Can you point me to a resource that describes the various firmware updates?
Thanks
Bevan
