would this sensor work with a Power FC?

no that is a 5wire wideband sensor.. you need a narrowband 3 wire..

ah lovely cheers simon. can a power FC run with a Wideband sensor?

no you need a separate unit.. you can feed a narrow band simulation into the apexi but you can with any ecu if you get the simulation sorted for the correct sensor voltages.

Oh right so its mainly a narrowband sensor ill be wanting then for the apexi unit and a wideband for a gauge for abit of a detailed sketch on what's going.
well the reason im looking into a new O2 sensor is because i believe mine is shot, what sort of voltages would i be seeing on my commander to check if its working correctly simon?

thanks

roughly 0.2~0.5 on idle and .9 on boost iirc.

you can switch it off..

ETC --> Function Select --> O2 Feedback, scroll right and press down arrow to turn it off and the symbal will change to indicate off.It will then use the fuel map only..

no problem

STi Ben

well i checked last night and its voltage is at 0.9 at idle. it does seem to go down to 0.6 but only for a split second, and then it goes down to 0.00 and then back up to 0.9 once it warm.
i took a pick of my commander display when the engine is warm if its ok to email it to you, just shows the voltages on sensors.

thanks simon

STi Ben

Hi simon
iv changed the plugs and gapped them at 0.6 but still im having the same problems
this is the pic of my commander once the engine up to temp.


if you need a bigger pic ill send it to you.

thanks
Ben
