alright i got my ecm spy cable today, followed the youtube vid hooked it up. it was initally close to 8 in the center, so i reset it back to 0 and than to 5.5 bike wouldnt run at all, idle for a minute than die. just to get it running well, i had to up it to 7.5, and it idles around 1300 now. i dont want to drop it more, because than it runs rough. any insight would be great.

To get the most accurate TPS reset, be sure the butterfly valve is snapping shut completely.  If it doesn't, you've had a "false" reset.  Pull off the inner & outer airboxes to be sure. After that, try a "hard" TPS reset if it's still off:  "Hard" TPS reset Not being a jerk, but all this is assuming that you're doing the normal TPS reset correctly.

IDK why I bother checking threads where stevenc150 was the last to post, knowing damn well he has it covered.

not being a jerk at all, i'm not sure if i did it correct. i followed the video of it, and snapped the throttle a few times each time i made an adjustment. i set the tps to 5.5, started the bike and it would die. but i didnt apply slight clockwise pressure to make sure the valve was closed/didnt take off the air scoop, so i'm going to try those today on my lunch break. is having it set to anywhere from 6.5-7.9 bad?

Those TPS values describe a throttle butterfly opening amount that is greater than normal. That indicates some part(s) of your engine system is out-of-normal condition. It may be an adjustment, excess wear, cleanliness, funky fuel map, etc. Leaky intake seals would be an example of such problem (not a diagnosis). Will engine still idle at 7 +/- now?

yeah idles fine at around 6.5 now. sounds like it may have an exhaust leak, but i do not see any signs of carbon around the manifolds. been noticing a ticking noise lately. on my lunch i'm going to check my static timing and make sure thats not f'ed up. could an old/non maintained K&n cause this?

Hmm, mine's been 9-10%. Lowest I've seen is 7% after a reset. Guess I should check it out, too. Applies to 08's as well? We don't have a idle adjuster, and that's part of the procedure.

Air-filter would be very restrictive to affect idle speed airflow: probably not a dirty air-filter.

well air filter was fine anyway. i'm going to check for exhaust leaks before i leave work. does it matter if the tps reset is done cold or hot?

I don't believe it should make much difference whether it's hot or cold on the reset. Just checking are you actually looking at the butterfly in the throttlebody and the idle screw itself. Turning the Knob behind the air scoop doesn't necessarily mean you've backed it out all the way.These things like to get bound up and fool you. you should really get a good visual to be sure, and apply slight clockwise pressure to the throttle grip. It should stick just a little when you go to move it the other way, If it doesn't stick, It's not fully closing.

well i realizd i was looking at percentage vs voltage, which there was a slight difference in readings there. so now i set it at 5.5 volts, applying slight pressure to it. also, when i backed it out the addition two turns according to the video, the throttle wouldnt move at all. right now it idles at just around 1050, maybe a bit lower. does it adjust its idle after running a bit? also, do you think that its possible for the static timing to be out after only 900 miles?

+1, idle adjustment cable can be binding & awkward. Grease its screw-adjuster @ throttle body when access is available. IMO, electronic ignition timing seldom changes "on its own"; an electronic system with no wearing parts.

Quote: does it adjust its idle after running a bit? '07-earlier (DIY adjustment) '08-Later (ECM controlled) Edit:  Oh, and yes there's a cold start enrichment, so after it reaches normal operating temps., the idle will change.

I was told to and now always remove scoop and cut zip tie to have adjuster cable as straight as possible. It can bind up, and it's pretty fragile. Also when the tps reading does not drop any longer and the idle screw is completely off the throttle body, is when I hit reset. I also back the adjuster screw all the way out, not just two turns. For my bike it allows me enough length to bring values to where they need to be and be able to adjust idle afterward.
