I bought a 2006 that was already built with a GR EIS 4000 the engine is a Jabiru 3300A, the problem I am having is the RPM's are reading off and I looked in the manual and seen that there are P/R codes for each engine. The manual doesn't explain how to set the codes, I emailed Grand Rapids Tech. a few days ago and haven't heard back from them yet, so I tried to call and ended up getting a generated message saying we can not take your call at this time (it was during their open hours).

Can anyone help me with getting the tachometer to read right? I would really appreciate it!
