The stock, non-custom ecu mapping is, to one extent or another,
usually a little surgy, notchy and abrupt at low rpm.
The stock fuel injection has
some unique issues that are not commonly seen - Custom tuning makes a big difference
in flatness below 3000 rpm and riding smoothness.
Tuning a PC's fuel mapping is going to make the the lowend
better than stock and allow proper tuning in the rest of the
operating range, On the other hand, buying a Microtec ecu allows
both fuel and ignition tuning - and that allows a decent tuner
to optimize ignition timing tables and boost lowend more than
using a PC alone.
Note: If a tuner has optimized the idle ign timing AND the
fueling with a Microtec, the idle speed will increase. If the
lowend is not optimized, the idle will not increase with the
Microtec installation. Adjusting the idle speed screw
takes an additional 1 to 2 hours because the idle speed screw is
buried between cyls 2 and 3. It's so buried, that it's
claimed that it doesn't exist and the way to adj. the idle speed
is to adj. the ignition timing. So, it costs more to
custom tune a Microtec because it takes more time. - but a tuner
can do better job.
See pic of throttle bodies below.
Note: Most modern motorcycles have ignition timing in the range
of +5 or +10 degrees at idle and the sameish at crankover speeds
and that's pretty universalish. Sometimes, on the MV
Microec ecu's. when you use optimal timing for idle, the bike
acts and sounds like it has 10 to 15 degrees overadvanced
ignition timing when the start button is pressed in - but, if it
manages to start without hurting the starter clutch and you let
off the button, it runs perfectly like you tuned it. So What to
do? It acts like it's too advanced below idle..
It's not like that on any Ducati Microtecs that I've
tuned.
Note: Oil leak at oil pan- The sidestand is mounted
directly to the oil pan and the sidestand, when overstressed,
flexes the oil pan and eventually compresses the oil
pan gasket and causes an oil leak. The owner / mechanic sees the
oil leak and hopes that the oil pan bolts are loose, and the
bolts near the sidestand are indeed loose. Then, he or she
tightens the loose bolts, then all is ok for a while, then the
leak starts again, then the bolts are loose again. This time,
tightening up the bolts doesn't fix the leak and the oil pan is
pulled and the gasket is compressed and shredded on the
sidestand side.
What happens is that the sidestand flexes the oil pan (which is
floating over a compressible gasket) and eventually squeezes the
gasket and allows the pan to float and saw it's way through the
gasket.
A bead of silicon sealant / RTV is a dead giveaway that the bike
has a problem with that gasket.
A thought: If you delete the gasket and use Three Bond non
hardening sealant (avail as Hondabond, Kawabond, Suzukibond or
Yamabond), you would add the rigidity of the crankcase to the
oil pan and decrease the troublesome oil pan flex.

ecu tuning for trackday bikes.
Here's
the MV Agusta 1000 f4, 04-07 throttle bodies.
The single small (without yellow paint) screw is
the idle speed screw.
The spring loaded screw (with yellow paint) on
the Master carb is to sync the slave to the
master.
The #1 and #4 butterflies are fixed to their
inside brethren.
The throttle bodies are equipped with the usual
air bypass screws.
They certainly do have a manual idle screw.

The extension of the laboratory
for engines of the Swiss Federal Institute of Technology was completed
in about 1935. Its architect was Rudolf Otto Salvisberg (1882-1940).
He had a successful career in Berlin but returned to Switzerland after
the advent of the Nazis. His architectural style was somewhat similar
to that of Erich Mendelsohn. The staircase of the laboratory is in normal
use but well preserved.
