well i dont know what is going on with mine, i ran it to the battery also to make sure it wasnt the problem and surely enough it wasn't. I cleaned it off with brake cleaner, did some tests on it,etc but nothin worked. I got some decent readings when i had it in the first bung on my downpipe, but i thought it was alot of heat so i moved it farther back to the 2nd one and now i get like no readings. I'll try a new sensor, but it would suck if its not the sensor and something else, then i'll be stuck without a tune. We'll find out tomorrow i guess.
