so, the day before yesterday i stop at my local auto parts store to pick up some stuff to clean up the rear wheel on my 1125... i also picked up these little led 194 bulbs for the 'marker' lights in the headlight... get to the shop, install lights, wash entire bike, even air dried it with a leaf blower (crafty, i know LOL) go to head home, thing runs like dog turd... falls on its face under hard accel, backfires and sputters, so i ASSUME i got an electrical connection wet, something along those lines, park it for the night, next day, same thing... so, on a hunch, i re-install the regular bulbs- problem SOLVED! I heard of this before with older 'vetts doing something similar if the incorrect wattage bulb was installed in the taillights, but i thought leds took less wattage... anyone have their 2cents they wanna throw in on this??

Not an expert by any stretch of the imagination. Here's a shot in the dark for ya. Some led's have a resistor(I think) built into the bulb. If so, I'm gonna guess and say that was messin' with the ECM some how. Don't hold me to it. I'm a real flake when it comes to automotive electrical.

I think it is just a coincidence. To check, you should install those new bulbs again and see if the problem repeats itself without the bike being washed.

I've seen Ford Explorer transmissions stop shifting with LED tail lamps before. Most of the sensors operate in the millivolt range, changing bulbs can alter a ckt over a volt.

Might want to check the baro sensor. They usually get installed incorrectly and may fill with water. The nipple should be pointing down and to the right when properly installed.

thanks guys for the comments back...

i dont think it was a coincidence, i literally pulled over on the side of the road and changed them, and it was right back to 'normal' which i half guess from reading other posts on here that my new ecm didnt have the 'latest and greatest' flash- but all in all, i love the bike... i hate to say it, but even the quirks... kinda like a high maintence girlfriend, lol...
I'm wondering if these don't have the resistor mentioned, and the ones you guys installed do, OR the ones you have installed with no issues draw a bit more than mine... the ones i installed were (Pilot was the brand i believe or APC) cheapy single led-type wedge bulb replacements- ive seen some online that have as many as 10 leds per bulb... they were not very bright, so i cant imagine they draw much at all- with the exception of if they do have the resistor built inside of them... i had some form of that when i installed intergrated led turn signals in my gixxer a few years back- those ones were fairly large in size, about the size of a kit-kat bar as i recall.

But again, thanks for the insight guys, im really glad i stumbled upon this forum, ive been able to learn so much about my bike on here
