none that I have ever heard about.

the 1800 engine is bullet proof the way it is, and it is totally controlled by the ECM,

there is no way to reprogram the ECM legally, the only company that used to do it, got slapped by the Feds.

he posted that cartoonish ad poking fun at all the fake "tuning" devices on the market. those are very popular with the harley crowd who buy them to justify the installation of noisy bent tubing referred to as exhaust systems.

you cannot tune an efi engine without being able to manipulate the tables and cells in the cpu programming, which involves very expensive equipment and training.

sorry for the confusion.

things change every day if a couple hundred bucks would get few mpg,s i would upgrade my old machine rather than buy new . i keep it tunned and oil changes up to date . i know these are wonderful bikes i love mine and ride a lot

its usually the oldest ideas that bring better mpg. like tire pressures, lessen brake drag, lose weight (a biggy) reduce air and rolling resistance, correct fuel (premium is not your friend), driving habits, state of tune, etc

it is usually the modifications that promise more power, cooler running and better fuel economy that are the cause of less power, hotter temps, and poorer economy! lol

yep... reason for asking about cams was i was in middle of adjusting valves. sometimes a degree or little lift can make a diff

You can....if you know the existing EFI map, and then alter the signals from the various sensors to modify where in the EFI map the OEM ECU is thinking it should go.

That is apparently what this little dongle is doing, although the only sensor it's modifying is the IAT:


So I suspect all it's doing is altering the IAT sensor value, making the ECU think the air temperature is cooler than it really is, so that it will dump more fuel into the intakes to compensate for the "denser air."

You might get a little bit of a power increase. But you're going to use a lot more fuel to get there.

Of course, you could probably get the exact same effect with a 10 cent resistor, but that's neither here nor there. :)

The real question is what are you looking to change with new cams?
If you are looking to make a better touring bike powerplant, good luck. Honda has spent a lot in R&D to get there. Look at the torque curves for the new wings, they have more torque at idle than most bikes make at max.
However, if you want to give up some things to improve others, speed is just a question of money. How fast can your wallet go?

yep, thats all any of those fake tuning devices do. you can hit the engine coolant temperature sensor with a hammer and accomplish the same. lol that aint tuning, that is destroying the tune. if it includes words like chip, fueler, piggy back, or quick install, it is always a joke. most (only about three ) tuning devices allow over 2000 parameters to be changed with use of a dyno and /or data logging and will need an exhaust gas analyzer. then you have to have a way to read/write to the ecm and keep the engine at a constant temperature for several minutes before moving to the next table. rinse and repeat throughout the temp range. its not like a camaro with o2 sensor eliminators . lol

Other's have talked about putting Rune camshafts in, but I've not known anyone who has. The biggest drawback to the Rune is that it more of a city bike. Meaning lots of RPMs at low mph.

i will say 1 thing if i was going to upgrade anything on these bikes it would be the air cleaner system that is the bigest pain in the ------ i have ever seen to change on a maintance item !!!!!!

the ecm was retarding timing and adding fuel..just like that fake tuner will cause. maybe if you have the existing problem(s) corrected you can spend money on tires and shiny things?

you replaced ecm and lost mpg. now you want to corrupt the new ecm and lose more mpg. now, im confused.

not wanting to put tunner on for ecm i just wondered about cams while i had apart adjusting valves . i didnt know if there was any new products out there that may be a little better than stock.

On some, when the ECM goes bad it begins to foul the spark plugs. So be sure to check those. Other things that cause poor mpg are dirty air filters, and valves that are not set to center spec.

just replaced plugs and air cleaner and set valves and sea foam in tank oil change now need warm weather and someone to ride it to see if fixed LOL ----air filter was cleaned and oiled after ecm didnt notice differance after that though. changed back to stock filter now to much trouble to get to to oil and clean other filter

oiling filter? k and n? if so, that is a huge problem.
