Hi Finn.
At Charlies request, I=E2=80=99m happy for us to keep the discussion =
public.
I hadn=E2=80=99t used the EM3 Engine Dump screen. Must check it out.
So I guess with a Renesis CAS but timing for a 3 rotor ignition and =
injectors it might run like a Harley!

So did the compiler get the equates wrong, or more likely the chips =
didn=E2=80=99t erase properly if it was previously progged for a 20B?=20
Worth checking the source for any semicolons etc in the wrong place in =
the list of EQU=E2=80=99s.
Did MPLABS read and confirm the burns?=20
Do you know what engine the EC3 was previously set up for?

Steve
