2008 Spyder runs bad as outside temperature gets hotter

[bfmtrader]

I have a 2008 Spyder GS/RS manual shift. Modifications are Leo Vince pipe and O2 Modifier. I have found that the bike will run great when I leave home in the morning (outside temperature 65-75 F). When the outside temperature gets to 90 - 100 F, it will start running rough, coughing, sputtering at low speeds, popping during deceleration. This is not quite as noticeable when I have stock pipe and O2 sensor connected, but it still happens. Is there a sensor on the bike that reads outside temperature and sends this information to the bikes computer to change the air fuel ratio? I have been fighting this good bike, bad bike issuer since I bought the bike two months ago. I have checked for manifold air leaks, made sure all air hoses are hooked up, replaced Y-Pipe gaskets to make sure there are no exhaust leaks. At this point I am hesitant to buy and install a Power Commander or Two Brothers Pro Juice Box. I need some advice/help.

HAve you had all the updates done to the bike? The purge valve software update in particular??

Yes-- the Ambient Temp sensor sends signals to computer to adjust afr.......

There's a temperature sensor right side front you can just see it though the lower air scoop,
Some were installed improperly or missing a foam cover.

When I locate sensor, is there a way to check it to verify it is either good or bad?

I realy don't know how you can tell, Unless it's Not bolted in its slot, or the foam is missing.:dontknow:

Thanks, I will check it for proper mounting and foam cover.

My temp sensor was located in the wrong place. Took a while to figure out what was wrong.

Switch to temp on the cluster, ryde around for a while and hot the engine up. If the cluster says a too high temp, the sensor isn't in the right place.
