Im changing my pr3 ecu which has 2 o2 sensors. I will be using the PM7 ecu and chipping it to run boost.

My question: Will i still need to use 2 o2 sensors? And other than wiring the vtec wire off a rpm switch, will there be any wires that are different from the pm7 to the pr3?

Thanks

pm7 only has input for 1 o2 sensor. should be pre-cat. wiring differences, I don't know, but it's not hard to search for wiring diagrams. check pgmfi.org or honda-tech.com search archives.
