This one is for the professional engine management tuner or
advanced do it yourself tuner of any of the more commonly
adjusted engine management systems--including but not
limited to Nissan, Honda, GM, and Ford.
The Multi-tune Adaptor installs into the standard 28 pin ROM
socket of your Engine Management Computer or memory adaptor.
It allows the use of a 512k ROM in place of a 256k ROM and
has a power input which will switch between the upper and
lower half of the 512k ROM. This allows you to have
two versions of software installed and to switch between
them on the fly. The switching is invisible to the
engine management computer and because it uses a power input
to initiate the switch it can be controlled by another
electronic device as well as a simple manual switch.
Common uses are to tune for multiple types of fuels or to
tune for a nitrous oxide system
Each adaptor ships with wire and gold sleeve connector
for connecting to the adaptor, a grommet to run the wire out
of the ECU, and a pair of matching left and right fender
badges. In some engine management computers there may
be tall devices on the board which could impede the
installation of the adaptor. In such instances extra
ROM sockets can be stacked on top of each other in order to
obtain clearance. The freeware software "Appender" is a convenient
way to merge two 256k BIN files into one 512k BIN file for
writing to a 512k ROM for use in our adaptor. It is
available at the following url.
