[waldo]

Searching around Im not sure.

TT 1jz soarer stock - hooking up to LM-1 AFR sensor.

Anyone know where I could tap into?

IG-
Comes from the ignitor, (and the DIAG box) and goes to the tacho.
Not sure if its also part of the DIAG box in the drivers foot well.

Thanks,

would you have a pic of what im looking for?

Where is the ignitor on the 1j?

Stick your head in the drivers foot well and locate the DIAG plug.
If there is an IG- pin, thats all you need.

As said the signal goes from the Igniter to the DIAG box and to the dash.

It should come out on pin 8 of the plug in the below pic. Black wire if I recall. Check for continuity using a multimeter to the pin labelled "IG-" in the DAIG box on the side of the engine (~0 Ohms resistance).



FYI, the Igniter is located in the engine bay on the passenger side strut tower and the DIAG box is mounted on the side of the engine.

Thanks very much guys. Ill track this down and give it a go.

The LM1 has been a good bit of gear, except it produces error codes when AFR quickly drops below 10 (which my stock soarer does on full throttle and higher rpm).
