The other two I.C's in the Memcal

As explained to me, the 18 pin is the netres, which sets the
fueling via the redundant fuel device.  For Limp Home Mode.
In limp home mode there is no ecm timing control.
  The 14 pin is the ESC chip, weither a netres or not I don't know.
But, it sets the acoustic footprint that the ecm looks for in
appling ESC controls.
Cheers
