I found a potentially good deal on a auto tune set for a power commander minus O2 sensor. Whats the cheapest 5 wire wideband O2 sensor available that would work for this?
Probably a Bosch LSU I would imagine. I have a slightly used one laying around too if you might want it… 50 bucks.
careful of ebay ones… ive seen some china “wideband” Sensors really end up being narrow band 5 wire stuff…
