Hi guys,

Ive had a custom front pipe made and it doesnt have a hole for the lambda to screw in, do I need it or can I forget about it ?

thanks

If you are running the O/E ECU, the lambda sensor is required for closed loop running.
On the M/Y 94, I think the lambda sensor is located in the headers at the collector. Look underneath at the front on the drivers side and it should be visible.

 

thanks mate, il check it out in the morning, spot on

 

il be running a scoobyecu chip

 

You still need a lambda sensor, assuming you intend changing the downpipe?
the new one will have a hole for lambda sensor as from 95 onwards the lambda sensor is in the downpipe.

Thanks for your time simon, mines a 93-94, il check its location today, thanks bud

 

I would expect it to be in the headers like Harvey suggests.. look in line with where airbox is or used.

If your having a custom pipe made - then surely it can't be that hard for whoever made to drill a hole in the pipe and weld on a suitable size/thread nut to screw the sensor in?

Could do it yourself if you have a drill and a MIG welder

So if the sensor does happen to be on the down pipe and not the headers - then it's not the end of the world.

 

yeh cheers lads, its been given to me by a mate who owns a engineering company and I feel it a bit cheeky to ask him to weld the boss in, so il get my other mechanic to do it if its required, but ive a feeling its in the manifold anyway so il be cool.

cheers fellas
