I've recently been informed that my placement of the o2 sensor on my headers is a bit too far away from the engine to get an accurate reading... You can see the wire hanging down in this pic, it's right on the other side of the old bung. The primaries are 28" long so the o2 is almost 40" away from the rear exhaust ports...
I am using a 4 wire in there and TMK it was working fine... but you never know... maybe the engine ran lean, got hot and that's why i spun the bearing.. it was having a hard time starting after the 25 minute drive to the strip. but the temp sensor never showed it getting warm...
Either way, i was thinking about using (2) 4 wire sensors after i fix the engine, one on the front primary and one onthe rear. Obviously i'll have to build a circuit to combine the 2 outputs for a useable signal by the computer, no problem there... but i was just curious if anyone had done this before? or if anyone had any thoughts on the placement of the sensor...
Thanks for any info,
Dave
