Throttle Position Sensor (TPS)

[ronnelmarc_21]

why dont we try to tie it up to the Ground line,,to obtain the maximum torque?..In my understanding if u're in the 2ND gear the 2nd gear indicatot light up to it means the pink wire is connected to ground during 2ND gear,..otherwise its floating/12V...correct me if I'm wrong

just wana share wth u guys bout da pink wire..I've grounded it for a year now n i'm satisfied wth my bikes's performance,especially during take off,i can even feel the torque at 4th gear..But i think, unfortunately, the top speed is still the same..Regarding the tps,i think our bike really need it as long as we still using the stock cdi or aftermarket cdi that use the data from it..Thus,if it is removed or broken,im sure our stock bikes would run weird..Just my theory though..Peace

 

[ronnelmarc_21]

thanks a lot for sharing that info and experience "SYFULL"..may be I can try it if I have time in removing the cowlings,...I just draw a conclusion based on the inputs and wiring diagram of our bike,...

Good Bless....

welcome bro...Then again,its depends on our personality n riding styles...N how mch we understand our bikes..Who knows,mayb it works to others but not thyself...Rite?

hii.. the pink wire comes from the 2nd gear.. its function is to switch ignition mapping for maximum torque because 2nd gear is the common position when we accel.. after switch to 3rd gear it becomes normal again..

sir how come my wiring don't have pink wire attach to the cdi? Refer to the attachment below....


its suppose to be besides the black wire right? if this is so then how will my bike now will switch to ignition mapping? did somebody have same case like this? or is this is a normal set up for yamaha sniper mx compare to the older model?

need advice on this... if anyone have any suggestion please comply, i just want to know if this is normal or what?

lately iv been experiencing problem with my top speed. my bike seem to limit rpm to 7k to 8k. even if i try to use rcdi still same effect.

i'm still wondering how to ground the wire.connect it with another wire untill the wire touch the ground or just make the wire touch the body of the bike?

- attach the pink wire coming from the CDI anywhere on the chassis

- I think this is the wiring diagram on how to ground the pink wire from the stock cdi with a switch option to turn it On or Off

still we have the available option to attach anywhere on the chassis

Please do get final confirmation on the wiring schematics before doing so...

will some one test out this mod in top speed please make sure its all stock

So does this mean if we apply this mode, the behavior.given to 2nd gear will be d same to the other gears??

hey bro Cerberus
i do not recommend cutting the pink wire.. better to adjust the tps degree or just get an aftermarket CDI..

Why is it bro??

 

[kojack]

Why is it bro??

i've done cutting the pink wire bro Cerberus, i must say there's not gonna be much difference wit this mods n the wiring looks kind of messy with the cutting.. better to try adjusting the tps degree, get an aftermarket CDI or changing to a stiffer spring clutch for a better acceleration ... you can still try it if you want. just my 2cents bro.

ok bro.. tnx... still it has increase in performance??

for stock yes bro Cerberus.. but just a little increase in performance. if you've already change to an a aftermarket cdi there's no need to cut the pink wire anymore.

Hello , I'm from thailand , there is way bypass tps or not , is not a code error show on Speedometer .
thank you.^^

What is TPS ?

Bro heres my analogy

WHAT IS TPS?
TPS or throttle position sensor is a sensor that is installed in the carburetor. open the fairing of the top of the carb
and you will see the tps.

Thru this sensor, The CDI will know the position of your throttle.
is it in full throttle?, the TPS will send signal to cdi
is it in 1/2 throttle or idle position ? the TPS will send signal to cdi.

The CDI needs the signal from tps so that the cdi will give the best best settings for the ignition timing to provide best power of your bike.

EXAMPLE (note: This is just simple analogy to show whats the use of TPS)


No TPS: Your on flat road, 100 kilos passenger, full throttle.
the cdi says: This is my settings, this is what i was designed for. i will just give this same settings.
besides i dont know whats happening outside.


No TPS: Going Uphill or mountain, 100 kilos passenger, full throttle.
the cdi says: This is my settings, hmm... im wondering whats happening outside? Is my settings correct? ahh forget it, i dont know whats going on outside so ill just give this same settings regardless whats happening outside. I dont care!!!


WITH TPS: Your on flat road, 100 kilos passenger, full throttle.

cdi says: ohh im already in full throttle, the rpm is high, i believe we are on a flat road because its full throttle and the rpm is also high.
The driver is speedmaniac!, ok, you are speedmaniac, I will give the best settings thats designed for top speed.


WITH TPS: Going Uphill or mountain, 100 kilos passenger, full throttle.

cdi says: ohh my , The throttle is full but the rpm is low... hmm.... why is that? probably its going uphill or we are going to a mountain, ok with that i will use the best settings for going uphill.

if youve noticed, most of the special bikes, high performance bikes have TPS. example of that are bigbikes, and motocross bikes who needs GOOD power at all powerbands.


In summary:

TPS is the eyes of your cdi. it will show the cdi whats happening outside.


Hope you understand my comics style of explanation...

nice explanation sir!
