I have a 07 streetglide, stock 96 with a big air cleaner and true duel exhaust. Bought it used a few years ago and it was running stupid rich, exhaust glowing and getting worse gas mileage than my big bore high compression Nightrain. Bought a SE street tuner and hooked it up to find that a 103 tune was in it. Reflashed it with the 96 with stage 1 air cleaner and duel exhaust tune and the bike ran great after that. This summer I did a bunch of suspension work, motor mounts and changed the LED colors in the guages and radio. While doing this, one of the wires pulled out of the ign switch and I had no voltage to the bike. Started pulling fuses to see if I blew a fuse. While pulling all the fuses out, my alarm siren started going off plus another siren that I've never even heard before, louder than the siren that normally goes off when I try moving my bike when I forget to have my keys on me. Disconnected the battery and it was still going off until I unplugged the alarm module under the seat. Plugged it back in, connected the battery and put all the fuses back in and siren stayed off. Found the pulled out terminal to the ignition switch and fixed it. Now since then, the bike just dosnt seem to run the same. Lugs slot more between 2-3 thousand rpm, even at 3000 rpm in 6th gear on the hwy. Checked everything over and found my spark plugs had loosened up, which seemed odd but tightened them up and it was better, but still ran funny. Put a couple thousand miles on the bike and just couldn't except how the bike was running, even thinking that with new front and rear motor mounts that maybe this is how the motor was suppose to feel, so I hooked the tuner back up and updated the tuner software. Now there's a smart tune feature and almost no options for a base tune, just the 96 with a big air cleaner, nothing about exhaust. So re mapped the ecm, used the smart tune plus leaned out some parameters that I thought were too rich and now my bike runs great, maybe better than before, cant really remember since i started this whole project before riding it much this year. I'm a 20 year auto mechanic, worked for all diffrent kinds of high end car dealers, have had 1/4 million dollar cars completely apart for months on end then back together and never had parameters change or lost in a ecm. My question is, did I do some back door ecm reset by pulling all the fuses out and activating the alarm? A ecm should not lose its program by removing power for a few hours at the most. Has this happened to anyone else or do I have one of these cursed bikes that's out to make me go batshit?

 

Allow me to introduce you to the concept of paragraphs. Your post hurt my aging eyes.

 

Post was easy to read.

I cannot answer your question if it's running good enough right now riding it and not overthinking it is a good option.

 

When you updated the software on the tuner, it was updated with compliant tunes. You'll forever be stuck with that garbage as long as you stay with the SE tuner.

 

I agree you need to buy another tuner and re-tune your ride.

 

Not sure what happened, but computer stuff can seem like magic sometimes....

FWIW.... It seems to me, once you flash a tune to an ECM, that is now its tune. The tune that was there is no more... it has been replaced by the flashed tune. That's why my PowerVision suggests to save a copy of the original tune. It will be forever removed.....

On many cars, they say to reset the ECM by disconnecting the battery and grounding the disconnected positive cable to the frame. If you somehow reset the your ECM when "investigating" the power issues, it should go back to whatever tune is on the ECM... which should be the flashed tune... I'm not sure why it wouldn't go back to the exact same tune you flashed to it... Unless, you flashed a base tune, that had some extras added to it that might be erased during a reset.... crazy eh?

Bottom line, you found the problem and got it working.... put the fix in your bag of tricks for any future similar issues....

Enjoy the ride...!!

 

This is my first experience with it, was thrown off because I'm used to the list of tunes that match your setup and then dial it in on a dyno or by feel. Is the smart tune really that bad? If so, what's the draw back?
