Dumbass Question.

[Cobba]

Well that was too easy. Should have looked before I barked.

On another forum I frequent the guys with Bonnevilles talk about reseting or zeroing the TPS after having done stuff.
I better go back and look to see what it was they were talking about too.
Might be something I needed to do to start from a base line before doing the auto tune.

ROFLMFAO. That's a classic.

Hanso. Thanks. Now I have to go and work out what a TPS is.
My poor shrunken by years of alcohol abuse brain is going into thermal melt down now.
Just when I thought I had worked out the answers someone comes along and changes the questions.

T= throttle, P= Position, S= Sensor, it tells the Ecu where the throttle is and is then controled thru Steper motors to the correct position according to the needs eg - cold start, hot idle , cold idle. If it fails the Tps is not talking to the ECU so your problems arise the primary TPS is just below the middle throttle body and I remember correctly the one that plays up.
Please anybody more knowledgable about these thing Pipe in And correct me If I am wrong

 

[Cobba]

OK.
I'm sitting out at the bike looking at the throttle bodies.
Haven't got the tank up but can see most things around the K&Ns as the bearclaw has had a haircut.
Up front, and quite obvious is most likely the stepper motor. Pretty big compared to any other sensors and such and has a plunger sticking out the bottom onto a push plate mounted to the primary link.

Above that, and right next to the throttle cable is a sensor which has to be the secondary TPS.

Between the first and second throttle bodies is what I reckon would be the secondary control motor.

On the back of the third throttle body is what I reckon will be the primary TPS as it aligns with the end of the primary shaft.

I'm also starting to wonder if I have done this to myself by accident and in some way damaged the primary stepper motor when washing the bike with a pressure washer.
It looks quite exposed out there with the modified bearclaw and I could have hit it a bit hard with the high pressure of the gun.

OK

well I learn't the hard way on a previous bike and that is High pressure water and Electrical systems and sealed bearing don't and I stress Don't mix not to mention
exposed Air filters gentle light press from tap pressure only I have had Sealed Wheel Bearing rust and seize up, and more recently acidently got water in the alternater on my St 1100 Honda, that little bo bo cost a grand.

Try reseting the TPS as soon as you get Cable but while you are waiting go to your nearest Auto shop and ask for a tube of Electrical Grease then go and unplug every plug put a bit of grease on the contacts and replug before moveing on to the next one it will a/ prevent loss of contact, b/possibly restore contact and you might even get lucky, and fix the problem. If you get a *****that tells you there is no such thing as Electrical Grease tell him to ask his Boss if the boss doesn't know go to another shop or auto electrian, The brand I use is Inox MX6 with PTFE it is in a white tube with a blue pannel with white and black writing it says it is a NO MELT,HI TEMP,EXTREME PRESSURE, PREMIUM MACHINERYGREASE, FOOD GRADE. it also says HIGHLY RESISTANT TO WATER, SALT, CHEMICALS AND DRYING. that is where the confusion comes in it dosen't say electrical grease, I thought my auto electrican friend was having me on when he asked me to pick up a tube while we were doing up a mates car years ago, all I can say is it works and if you look in the plugs you will probally see some in there just top it up if you happen to be pulling a plug apart give the tube a squeese.

 

[Cobba]

Yeah.
Know the stuff you 're talking about.
I'm actually hanging my head in shame as I'm starting to think that this is what I've done.

Ok. Tomorrow I'll do a trip into town, get some goo and go over the bikes electrics.

Have been looking at the tracking number for the cable. Was delivered to Auspost at 2pm on Monday. Should be here tomorrow.
Looks like I'll be shutting up shop for the day and trying to sort all this out.

OK just done a search and the newre TPS has blue inards now I not sure if I would want to remove the TPS to find out cos I believe there is a right a wrong way of setting it up when you put them on, so unless you have a work shop manual which I might add someone here abouts has a copy on line

 

[HansO]

here it is you have to download it to view it https://acrobat.com/#d=CxB82igmUQQ7HPVtvGOuUA

 

[Cobba]

Yep. Got a manual and have just been reading about remove and install on the sensor.
Not something I'd muck with as it needs the diagnostic tool to reset.

Maybe something that I could do after I have the lead and laptop set up but still won't be rushing into it.

Tomorrow will tell. Lets hope that a new tune installed sorts it all out.

In TuneECU, under the tests tab, there is an option for "reset adaptation". In Tuneboy, I have always done this after loading a new tune. However, in TuneECU, there is also a "reset TPS" option under ECU in the Map Edit tab. This supposedly resets the voltage at closed throttle but then you have to turn the engine on until the TPS button at the bottom goes green according to the TuneECU manual. I don't know about the TPS reset. I would first load the new tune and do the reset adaptation first and see how it works before resetting the TPS. I don't see how you can set the TPS just with software. In the service manual, at closed throttle, you loosen the TPS sensor retaining screw and rotate the sensor until the voltage (which is displayed in Tuneboy and I assume TuneECU) is 0.6. Then you tighten the screw. The secondary TPS sensor voltage is adjusted similarly

Well cable arrived this morning. Sat down and started to try and download all the programs.
By 1pm I had lost the plot, called it a day and decided to wait for my young bloke to get home from school.
Thank god for 16 year olds.

Till then I went over the bike and checked the K&N install compared to the post here.
All pretty much the same except for the location of the O2 sensor which I moved closer to the throttle bodies. Probably wasn't an issue stuck out thru the fame in front of the tank, but not how it was discribed, so moved it.

Also removed the secondaries while I had it apart. Not sure if this was a good thing or not. A lot of people seem to be doing it but when reading thru the TuneECU install post it said not to.
I took it for a ride after and it didn't seem to make any real difference to the way the bike rode, infact actually seemed to retard it a little.


I had done a lot of reading by then and had a fair idea where I wanted to go so when my son got home at 5 it was just a matter of the boy finding the correct paths to get there.

By 7pm we were ready to do the do and we did.
Program removed was a 20145 which turns out to be a Jardine fixed, whatever that means.
100% secondaries and 6800 Rev limit.

New program was then installed and bike gave a burp when it all finished which made me feel good.
Disconnected the laptop and stuck everything together and off for a insect filled dusk ride.

Bike seemed to run a lot smoother than before and reduced the backfire by maybe 50% but it didn't fix the cold start/ low idle issue I have, so now off on another cause.
Will sit down with the young fella again before long and see if we can reset the TPS and check anything else available.

Thanks again for all the help. I must say that today was a big learning curb for me and I am now a lot more knowing of the workings of my bike for it.
What a brilliant forum.
It's good to have such a wealth of knowledge available.
