Hi guys, been searching about, looking for the wire diagram for the Lt10s series. The Microtech site (www.microtech-efi.com) has diagrams for all there other ecu's but not Lt10s. They have a link for the Lt10s wire diagram but when u down load it and open, its the Mtx8 diagram. My setup has no Oxygen (a/f) Sensor, really want to install one, but dont know what color wires to conect to the sensor. Gman where can i find the Lt10s wire diagram or can anyone help with the wire colors for the Oxygen Sensor on the Lt10s series???

 

Try the black/red wire.

 

Is that black with red line? And are u 100% thats the one? Cause i dont want to stuff anything up. If anyone has Lt10s wire diagram please post.

 

Hi, here it is.

 

Dont bother connecting it. Waste of time.

And its the black/red wire.

 

Thanks kalliR, this will make things alot easer to understand, thanks again.

 

Hi rx72c, wouldnt it better for tuning when i can see what the a/f ratio is doing?

 

What rx72c is trying to say is, unless your lt10s is configure for a wideband from the dealer, its worthless cause is not accurate enough for tuning on the road.

 

Hi mazdamigastos, is there anyway of finding out if my ecu has wideband installed? And what is it? Thanks mate

 

100% it isnt unless you specifically asked for it.

mazdamigastos is right in what he says

 

Take a LC-1 from Innovate. It's better and cheaper.
Look at www.innovatemotorsports.com.

 

Hi , found an AEM wideband a/f kit, full digital display in real time .5v for only $350 Australian dollors. Thinking of going with that, thanks for ur help. :-)
