PIM-2 & DATA EFI Controller Box Product Review
The one aspect of running this system that you
will want to pre plan is having the ability to
either weld in the Air/Fuel -Oxygen Sensor bung
or have it done for you by a local welder. The
process was handled here and took only a few minutes
to TIG in and installed at the recommended location
detailed in the instructions.
Removing and re-installing the fenders took longer
than installing the system and soon we were ready
for a test ride. "Even better" were
the muffled words coming from behind the rider’s
helmet as he stopped briefly to relay his thoughts?
No doubt the installed MAP had done its job. That
was a big relief off my mind as I was now confident
we could run the ATV as hard as we wanted without
fear of carnage!
PIM-2 Air/Fuel - Oxygen Sensor Bung was
easily welded into place on the Yoshimura
RS-5 Exhaust system
The system itself is comprised of the harness,
the D.A.T.A. box and the PIM-2 system and is a
complete system, meaning you won’t be running
to the parts store for this or that. It includes
a mounting bracket as well as Velcro and wire
ties to keep things in place as well. The PIM-2
and D.A.T.A controllers will allow you to infinitely
tune your fuel system for peak power. The PIM-2
and D.A.T.A controllers come pre loaded with two
maps. Other maps are available for download from
Yoshimura if needed. For us, the complete system
seems to be more then adequate and its self tuning
sure beats changing jets! We can now visit Yoshimura's
website and tailor our system to our set up or
change to a new set up if our needs change.

Suzuki LTR 450R with the Yoshimura PIM-2
and D.A.TA. Box installed
Now the downside....the price. Nothing these
days is cheap and this type of system will make
you cringe. With a MSRP of $329.00 for the PIM-2
and $429.00 for the D.A.T.A system, it is far
from cheap, but you do get a system that allows
infinite control and tune ability with Yoshimura
backing it all up with outstanding service and
industry leading quality. This is the downfall
of EFI and ATV's but from the number of these
systems on the market it must be worth it right?
Without a dyno to back up our "seat"
dyno, we can only speculate. The inexpensive "Cherry
Bomb" works extremely well but it alone can't
handle the changes needed when you start building
the engine as we fully expect to do when this
one starts showing signs of getting tired. So
in our opinion, if you plan to make significant
changes to the engine then this system gets a
big thumb up from us.
Now I have to question if any real gain came from
the system itself, but that is not the whole picture.
Having the control and safety built in is and
for that I feel it is worth the money, maybe not
the price but you get the point! The proof in
the pudding should come alive once the engine
is built and we need the adjustability this system
is designed for.
