Air intake senzor, and not just

[azbiza]

So, here it goes.

1.)
On my odometer, if i longpress the reset buton, the time changes to the temperature of the intake air.
My issue is that this always shows 12c, no mather if its hot like hell, or cold like in Siberia, this value does not change.

Is there a way i can test if the sensor is working or not?

2.)
The previous owner of my bike has replaced the front turn signals with aftermarket led like small signals, and when i turn on the turnsignals, they blink twice as fast as they should (the front and the back blinks are in syncrone).
But when i use the emergency blinker, the four blinkers blink as they should.
Whats the issue here ?

Thank you in advance guys/girls .

For the flashing issues.

I couldn't find anything re checking that sensor in both the S1 and S2 Yamaha shop manuals..

1st, I would check that the sensor is still in place and didn't fall out...

2nd Un-plug and re-plug the sensor making sure the connections are clean

3rd Un-hook the battery for an hour or two and see if that re-sets it.

Should all those be fine;
**I'd pull the sensor, check resistance at room temp.
Then check resistance with maybe a hair dryer pointed at the sensor. It should show some difference.

If it does NOT change at all, by deduction, your switch is likely faulty..

Thanks for the tips.

I have lifted the tank, and located the sensor, and than iv'e noticed something fishy.
The previous owner put in a a MEMJET something, and after reading about it this may be the reason my intake temperature is always the same.
I have no idea if this MEMJET is good for my engine or not.
(btw disconecting the sensors wires resulted the LCD diplay showing -9c so i guess the cabling is OK)

Anyone have any experience with this "chip tuning module" (as i understood it does that) called MEMJET ?

Here ya go! All about it;

Memjet EVO power module


Long story, but from that link;

"THE MEMJET EVO ADJUSTABLE PERFORMANCE MODULE IS DESIGNED TO IMPROVE THE PERFORMANCE OF FUEL INJECTED MOTORCYCLES. The MEMJET Adjustable Performance Module has been engineered through years of research and development on the Dynamometer, Off-Road Enduros, Road Racing Bikes and FIM Land Speed Record Bikes. Our goal was to offer the enthusiast a simple to install power maker that would offer the end-user an adjustable inexpensive tuning device.The MemJet Module is simple to install and tune. It has Plug ‘n Play connectors that exactly match the OEM connectors on the subject application. It affords a simple, economical and efficient way to tune effectively without any expensive dyno-tuning needed. The MemJet Adjustable Module acts directly on the IAT sensor’s values. The IAT is one of the most important sensors that the ECU polls to call up the proper on-board Fuel Injection and Ignition mapping. The MemJet Module sends a colder/denser air value to the ECU through the IAT port; the ECU will then call up on-board mapping that will be more aggressive. The ECU will establish a new series of necessary changes to the Injection and Ignition mapping through an established algorithm within the ECU.When you increase the value on the MemJet dial you will progressively dial up more aggressive mapping. To find the best “Performance Mapping” for your application take a 5 -10 mile adjustment ride – Slowly increase the values on the MemJet Module dial until you find the perfect setting for excellent engine response at all RPMs. This will be the “Performance Setting” that will produce the most overall power throughout the entire RPM range. As a by-product of more power, the low end jerky throttle, lackluster mid-range and high RPM issues are completely resolved! The engine will be smoother, more powerful and it will run cooler due to better mapping. For this reason the MemJet Module will be of benefit to both stock and highly modified applications with or without catalytic converter! The Adjustable MemJet Module can be re-tuned as you further modify your application. Do not confuse the MemJet Module as an ADD Fuel ONLY Device. The MemJet Module just empowers the stock ECU to call-up the best on-board Injection and Ignition mapping for your stock or modified engine’s needs"


Seems its doing what its supposed to do, put an artificial temp # instead of letting the OEM sensor function...

Yes, that is my concern as well.
Ive read what you have pasted in from that website, but was curious if some of You has any personal experience with it, or with something similar.

No experience what so ever with it.

My bike is bone stock short of Iridiums and open Scorps and runs great!! I don't screw with what isn't broke..

If I bought a bike with any added on fuel alteration system, it'd come off the bike before it would even be registered.. Just one more thing to break..

Folks mess with fuel systems, etc, loose mileage sometimes, get flat spots, backfires, to gain a couple HP, maybe...

Mine doesn't do any of that. 48MPG around town, no backfiring. IMO, Yamaha did fine setting the tune, at least on my S2..
