TuneECU - Install/Adjust new Pri TPS

[Tom-Hamburg]

Hi Cobba,

I myself had no opportunity to perform this setting on a Rocket.
But there give a very good sticky in the "http://www.triumphrat.net" where these
settings a Sprint1050 is described. Maybe clarify this sticky the outstanding issues from
you.

Here the link: TuneECU TPS and ISC Stepper Adjustment - Triumph Forum: Triumph Rat Motorcycle Forums

BR, Tom

Tom.
Can I ask you to clarify this a bit better for me please.

I'm gathering you mean that the throttle is manually opened fully to read the TPS?

Where abouts is the adjustment done from???

How critical is it in relation to the correct running of the engine??



I do understand the initial setting of the TPS and what I believe to be the correct means for setting the Idle Controller motor but haven't heard anything of the fully open setting till now.

I am about to fit a new TPS as soon as I think I've got all the answers. Want to balance the throttle bodies as well when I do it and get it all done right the first time.

Any advice would be much appeciated. Also links to the balancing would be good too.

Cheers.

Thank you Tom.
I now understand, and was doing that step correctly already.
Must of read that thread some other time as it was that information I was using.

That opens up another question. He's talking about doing all this to a 1050.
What are the correct voltage figures for a Rocket?

I've set my TPS at .6v and the stepper motor at .74v, but now I'm wondering where I got that info from cos I can't seem to find anything relating to it for a Rocket 3 again.

I also haven't been doing the "Reset adaptions" part properly either as I disconnected the laptop from the bike and just did a 12 minute auto tune.
Hopefully that was the same thing anyway.

your voltages are ok cobba as there is a + or - .02 volts. so your stepper is only off .02 volts. you could mess with it and get it closer but it is within tolerance.

 

[Cobba]

Thanks Warp.
So correct voltage readings are TPS @ .6v and motor at .72v. Yes/No???

I must have it pretty right as the bike seems to be running a heap better and am getting engine braking again.
Economy has been non existant since I got the bike back then too with the light coming on anywhere between 160 and 200Ks
Have been 2 months of eradic riding trying to fix this f#*ker. Glad it's all sorted.

Off to burn a tank of fuel today and see where it's at.

es .6 volts +or - .02 volts the steper motor moves .12 volts so if your right on you will see .6 and then .72 when the t=stepper actuates during the test. likewise if your tps was at .61 then you would see .73 volts once the stepper moves. your all good so you shouldsee a fule consumption change unless you twist the throttle hard like I do

What a blast.
Picked a course that had lots of mountain roads in it and very few towns as I just fitted a new front tyre yesterda and needed to scrub it in as well.

Went out with all good intentions of being a good boy but just as I was getting to the bottom of the ranges I came across 4 bikes doing about 115Ks. The back marker was on a Thruxton and the others were 2 Jappa's and a Beamer.

Sat with them patiently for a few minutes but my right hand hates being at the back of any group so on a straight away I blasted past then and into the hills as around 140.
Met another 2 a little further up the raod and blew by them as well.

Just as I got to the top of the mountian I realised that one of them had come with me, and it turned out to be the Thruxton.

Well he tailed me down the other side and could of passed me a few times in the bends but I kept making big openings on him in the short straightaways.

Stopped at the bottom and had a bit of a chat with him and he's local to me so will have to see if I can find him again some other time.

Anyway. Fuel economy???
Didn't relly change damatically but then I was on and off the gas all the time and hit 200 on a few occasions so the real truth would be that there has been an improvement. Light came on at 180Ks and that will be about 16 litres when I fill it again.

Doing a casual Highway run on it tomorrow so that will really tell the truth.

Cheers.

Hi,

Initial setting (throttle fully closed by diagnostic device): 0.60 V ± 0.02 V

Final adjustment (throttle fully open by diagnostic device): Initial setting voltage + 0.12 V ± 0.02 V

Source: Technical News 110, created by Triumph, dated June 2009

According to the TN 110, you have it set correctly.

OK, after much stress over "did I just screw up my bike", things have been sorted out. The TuneECU documentation is not the most clear on this subject but the software works great after you figure out what to do with it.

To change the Primary TPS, here are a few clarifications that I hope will help the next Captain.

1. Change out the Primary TPS as described above until you get to the voltage setting part.

2. Hook up your computer with TuneECU running and turn the key on. DO NOT START THE ENGINE. (You may want to prep by removing the 20 amp headlight fuse to save your battery.)

3. After TuneECU has connected to your bike, verify the connection by clicking on the Diagnostics button in the upper right corner. This will open the Diagnostics page and gather some readings from the ECU. You might want to note the value for the Throttle setting, however, DO NOT USE THIS VALUE TO ADJUST THE TPS VOLTAGE. This is where I made my mistake and the Idle Stepper Motor was out of adjustment.

4. Now click on the Tests button in the upper right corner. You will see the Tests & Adjust section on the lower left of the screen.

5. To set the Primary TPS, double-click the "Adjust ISCV" checkbox.

SIDENOTE: this is a weird software interface. A checkbox implies a single-click to "check the box", i.e. turn it on. It was a little aggrevating trying to sort out this interface.

6. The checkbox next to the "Adjust ISCV" text will turn solid and whirring sounds will start coming from your bike in the area of the throttle bodies. You will also notice that the Cyl 3 (bottom) MAP guage has changed to read the TPS Voltage.

7. At the bottom of the window some text will appear instructing you to move the TPS until the value reads .060 in the digital part of the gauge and that the arrow is centered at the top. Make adjustments as necessary.

8. Double-click the "Adjust ISCV" text again to continue with the adjustments. More whirrings will occur and some new text is displayed at the bottom of the window. This time it asks you to adjust the TPS until the value reads .072v. You should not have to move it at all but this is just a verification step apparently.

9. Now you can tighten down the torx screw CAREFULLY.

10. Double-click the "Adjust ISCV" text one more time and it will go through a Reset Adaptives process. The text at the bottom of the window will tell you to wait 15 seconds and tell you when it is complete.

11. Turn your key off and disconnect everything. Plug your headlight/starter fuse back in and start your engine.

12. Pray that you did everything right.

Thank you for this post.
Just replaced my TPS by following these steps and my bike runs great.

Thank you for this post.

Ditto. Good to have the bike running well again. Installation and adjustment went smoothly, hardest part was getting tuneECU working as it should.

No, this is not only a verification step, this is the second setting step, which is corrected on the adjusting nut at the "idle speed controll stepper motor arm, if the second value is wrong.

For example, if the valtage measured was 0.6 volts in the first step, then the correct setting in the second step would be 0.715- 0.725 volts.
