Apexi Turbo timer reads A/F ratios out of ECU with single wire attached to one of slots. is it possible to use this timer with wideband O2 which has 4 wires? anybody done this before?



thanks

 

It is not reading O2; it is reading either a 0-5 or 0-1v output. It should be possible to use with any aftermarket 02 unit that has an output channel. Keep in mind that this will only be accurate if there is no difference in ground between the turbo timer and the 02 unit.

 

ok i see but my wideband O2 has 4 wires and this apexi timer has only 1 wire to connect to ecu for A/F readings. how can i hook my wideband O2 to this timer?
