Wrong Tune And TPS Question

[Mark Dunn]

Hi all,

I have an 09 standard (bought new in May, now 2300 miles) and decided I want a bit more 'oomph' in 1st and 2nd. However, I didn't want to go balls-to-the-wall like the GiPro does (at least, not at first). So, I modified the factory standard 20222 a smidge. Anyhow, I hooked up Tune ECU for the first time today (works well) and noticed that the installed tune was actually 20225, - which is the tune for TORs with cat in place.

I decided to load the regular 20222 tune instead of my bastardized effort to see what it's like. Well, it's smoother, about the same response-wise and has no decel burbling (the 20225 never actually popped). Gear changes are less jerky too. Why a new bike had the wrong tune in it I don't know. Any ideas?

Secondly, while hooked to Tune ECU I decided to check my primary TPS adjustment. I couldn't get the voltage reading any lower than 0.61V and no higher that 0.62V, no matter where I adjusted it to. Obviously, those voltages are within spec' (just) but I was surprised at so little change. Is that normal?

Regards,
Mark

Mark I am not sure about checking the TPS with tune ecu but I want to ask when youn did this the bike was off wasn't it and you tried adjusting the one at the rear of throttle bodies closest to the rider ? Again I am not trying to sound lame just checking the basics first. I will be messing around learning the tune ecu today eo see how it differes from tune boy. I will look into the tps adjusting/checking. Your voltage should move all over when you rotate it. As for tunes many people share tune and this of course is great but one should always be careful as the same set can varry widely. One of the biggest varriance is the fuel. Either by different gas companies or running the wrong octane the the tune was developed for do to various timing differences.

Wayne was amazed how different the two Rockets were on the dyno with the same Power Tripp tune.

Anyway we need to verifiy you have a good TPS and your connection is good. When I question a connection I try a simple test or two to see if the bike is truly linked up. Fan Test isa good one to use. Also Speedo/Tach test.

Hope some of this babble was some help

Hi Warp,

Thanks for the info'. Yes, the TPS I adjusted was the one at the front and the engine was not running.

I'm considering removing the TPS to eyeball the the inside part and make sure there are no obvious issues. From a photo I saw of the insides, there's a little cog that has internal teeth that I assume slides over a shaft in the throttle body, - is that correct? If so, I'm wondering if that cog can be turned a little so that it engages in a different 'home' position on the throttle body shaft. I thought I'd better ask here first as I don't want to get myself into trouble. :-?

The TPS housing and throttle body both have a paint mark on them indicating the original factory alignment and in the end, that's what I used for the setting when I retightened the TPS.

I appreciate the input from you and Wayne.

Regards,
Mark

Mark you are on the wrong TPS sensor. the one you want to adjust is the rear one its on the third throttle body this is why you are not seeing voltage changes when you try adjusting it. your on the secondary which does not matter if your secondaries are set to 100 % and they are not there.

Oh and Wayne I was one of those others that was amazed!!!!!!!!!!!!!

Hi idk and Warp,

Why is my brain so small? I re-did the adjustment using the correct sensor and all is well.

I'm pretty sure I got the secondary TPS in to same position it was in before I inadvertently adijusted it, but is there a way to easily check the voltage?

Regards,
Mark

EDIT:
Not to worry, - the secondary TPS voltage is shown under the 'Diagnostics' tab in Tune ECU. I checked it and my previous eyeball attempt was very nearly spot on, but not as perfect as an anally retentive person like me requires. :razz:

Mark

Was gonna say "sounds like you were working on the 2ndry TPS" but ya got it all worked out by the time I read to the end of the posts!! :lol:

I went for a 60 mile ride and she's purring like a well spanked mistress. Luverly.

Glad to hear she is responding well

"The Secondary TPS is at the front, near the throttle linkages, and should be set to .72 after the Primary TPS is set."

Please clarify, idk/Ian - I set the Idle Stepper Motor at .72 and have never even checked the Secondary TPS. Am I missing something here?

Thanks,

(EDIT: just checked manual and it looks like secondary tps should be set to .60 too)

DC your OK both TPS sensors get set to .6 volts the iddle stepper motor gets set to .72 volts during the ISVC reset if needed.
