Want your Star
Eluder 1900 / Star Venture 1900 to
feel like it has real throttle cables with no jerky throttle?
This is the best result possible in driveability and power anywhere for
this model - our proprietary software guarantees it !!
My Yamaha Star
Eluder 1900 / Star Venture 1900
ECU programming (Re-Flash) includes the following:
*****REQUIRES PREMIUM FUEL*****
1)
Fix all fueling problems inside the ECU.
(The ones that cannot be fixed with an
external fuel tuner or other commercially available methods)
a) All gear dependent maps
equalized
b) Main fuel tables (A/n) - adjusted in all active throttle positions.
c) Vacuum tables (MAP)- adjusted in all active areas.
d) Emissions compliant sub-routines that affect driveability - turned
off.
e)
All YCCT (Yamaha Chip Controlled Throttle) response
delay filters (detuning items) - turned off.
f) Deceleration tables thoroughly tested
and re-adjusted for best closed to part throttle response.
g) O2 sensors disabled - No need to unplug,
or can be removed if desired.
2) Raise rev-limiter to 5500 rpm
This allows full power development for
this engine
3) Disable fuel cut - ie; Jerky throttle
Don't
know what "fuel cut" is?

Disabled: https: https://www.youtube.com/watch?v=0jrDHTcHwN4
Live datalog Disabled: https://www.youtube.com/watch?v=7i2vCGnyuGk
a)
Engine stays running when the throttle is closed.
With stock ECU programming, the injectors are not running when you decel.
(please
see the demonstration videos above)
b) Gets rid of poor, imprecise throttle transitions from closed throttle.
c) Eliminates all feelings of driveline lash and jerky, delayed throttle
response.
d) Changing gears is dramatically improved.
Without fuel cut disabled, there is no "neutral throttle"
This is the direct cause of your touchy, jerky throttle because
the engine isn't running during
decel.
e) Dramatic improvement upon re-application from closed throttle (in all
riding conditions).
(Throttle re-application response feels like our old carbureted bikes
used to feel)
f) No need for a different throttle tube ratio to try to prevent jerky
response.
(which it cannot do anyway)
g) Gets rid of annoying popping and banging during decel and when re-applying
the throttle from closed.
**Open mufflers with
very large baffles will still pop a little**
4) Close AIS valves electronically
No
need for block-off plates for air injection system
No
popping on decel !! - **Open mufflers with very large baffles will still
pop a little**
No hoses to plug - Just plug in your ECU and go !!
5) Reprogram YCCT for best response
and remove power restrictions & torque limiters
(Yamaha
Chip Controlled Throttle)
YCCT throttle maps are just different throttle ratios, and receive
all flash benefits... across all the modes.
a) Allows all of the 1900 engine's available power - whenever you ask
for it.
"Sport" mode uses original throttle ratio programming with full
throttle restrictions removed.
"Touring" mode
throttle ratio remains 100% original.
b) Immediate engine response to the throttle with no restrictions
(no vague feeling from throttle when leaving a traffic light)
c) Low rpm power is dramatically improved, while
preserving fuel economy.
d) Response delay filters turned off - part of original
detuning.
e) Engine responds
and feels just like a cable throttle - throttle does exactly what your
hand does instantly.
No more "vague" response - especially off idle leaving from
a stop, and low rpm operation
f) Enable 3rd YCCT mode - with my own custom linear throttle ratio map.
(This is optional - Just indicate it on the form
when sending your ECU)
6) Complete custom re-curve of ignition timing
a) Set main timing
tables for maximium power and driveability across the entire rpm range
and all throttle positions.
This also helps provide better fuel economy, and less vibration when cruising
and moderate acceleration.
b) All gear dependent maps equalized and adjusted for best power and fuel
economy.
Adjust timing to be the same for all gears.
c) All emissions compliant /detuning sub-routines turned off.
d)
Gets rid of part throttle timing retarder for more response and less vibration
when cruising and moderate acceleration.
7) Fuel
economy -
Not sure what it is yet
- usually better than stock with my programming.
8) Reduced
running temperatures
Reduction of heat flow from engine that
cooks you while riding.
9)
All power & speed limiters removed
a)
Cruise control maximum speed limit can be lifted.
b) Cruise control can also be enabled in 1st and
2nd gear as well as lowering the minimum set speed limits.
This will allow you to set it at any speed.... in
any gear.
These
are optional - just indicate it on the form when you send us your ECU.
10) All driveability inhibitors removed.
Eluder / Venture 1900 engine revs instantly, and offers excellent fuel
economy too !!
11) Free updates when/if we make improvements.
(shipping not included)
12) Return your ecu back to stock at no charge for any reason.
(shipping not included)
13)
Anything that compromises performance and/or driveability is eliminated.
Includes
fueling changes specific to your exhaust
External fuel tuner not needed - just plug in and go !!
All testing and tuning was done in house on my personal Star Eluder 1900
shown above !!
Dyno tuning not necessary !!
We can reprogram for USA & Canada
Ivan's
Performance ECU flash is for CLOSED COURSE COMPETITION USE ONLY !!
ECU
reprogramming may not comply with federal safety/emission laws !!
ECU reprogramming may not comply with your warranty !!
*****REQUIRES PREMIUM
FUEL*****
See Eluder / Venture dyno charts below
***** All dyno tests
done in 5th gear w/premium unleaded 10% Ethanol fuel*****
*****REQUIRES PREMIUM FUEL*****
All Stock vs Ivan's ECU programming
A popular mod is to remove the baffle plates
frome the stock mufflers with a hole saw
*****Catalysts should be left intact in order to preserve
the power between 1700 and 2700 rpm*****
Gains from modding the stock mufflers
Replacing the mufflers with aftermarket slip-ons & ECU flash as compared
to all stock
Comparison of low restriction mufflers as compared to modded stock mufflers
w/catalysts intact
The strong negative resonance caused by not having the catalyst will affect
the fuel mileage in the 1700-2700 rpm range
Good resonance adds power in the 2800-4400 rpm range
This is something that cannot be changed by fuel and ignition settings
- it can only be changed by exhaust design.
