Could someone please tell me if the standard phase 3 (or any phase for that matter) is fitted with a lambda sensor?

All the engines i have dont have the exhaust and i would like to make sure. I ran my car last year without one fitted, but now it has been suggested that this could be the cause of my power problems.

I cannot see anything obvious on the wiring loom to suggest there is a sensor, but most of my looms have been butchered either by me or by some other clueless fool....

Hopefully this is a simple question to answer.

I have recently bought a 4 wire sensor to fit when i get round to using the Megasquirt, but would like to know should there be a sensor there anyway?

Some do some do not.

A mate of mine has an AE86 which has one but the AE92 (which is newer) that we pulled our engine from did not have one.

Some TVIS engines had them but the later phase three used MAP sensor only.

I'm restarting the MSquirt route shortly now I'm mobile again, I've just made a dual VR input board so i can just use the standard Toyota dizzy.

If you look at the MSnS pages they do a dual VR input software just for this.
