Thanks for asking your question. I will try and help you out.

So you have installed a newer 3406E and are using the old electronics from the original 3406E?

what do I need to do to fire up my engine..

Unfortunately the older ADEM 2 electronics will not work on the later 3406E with ADEM 3 electronics. They are very different electronic packages.

The only way to make it work is to install the later ADEM 3 electronics on the engine. It can not work with the older electronics.

I am sorry. I wish there was a way to modify it to work.

Please reply back if you need more help or have more questions. I am happy to assist.
