lambda sensor - which one?
02GF74 - 21/11/07 at 04:47 PM

is there any particular lambda sensor that is best/cheapest etc: that is recommended for use with MS?

Do motorcylces use lambda sensors - wold they be physically smaller?

incidentally google brings up reference, some mamnuals that don;t seem to load so where is MS site - megasquirt.com is a bit dodgey

is this one ok?

best job is to use a 4wire example.

then you have an ground for your signal.
also there are more expensive wideband examples out there but you will need a extra controller for those.

Bikes do have labda sensors, don't think they will be any smaller (much)

If you want a lambda sensor for mapping, then you really need a wideband unit along with it's controller such as the Inovate LC1.

Narrowband units tell you if the engine is running rich or weak, but not by how much, and are really only useful for making an engine run around stoichiometric to ensure a catalytic converter works efficiently.

ok so the question is refined to which wide band lambda sensor shold I be looking for - and how can I tell if a sensor is narrow or wideband?

I would be looking to use megasuirt, and yes, the idea is to use sensor for mapping then once done, remove it.

The vast majority of sensors for production cars are narrow band units. The operation of a wideband sensor is fundamentaly differeent to that of a narrow band which just produces a a high or low voltage. A wide band sensor requires a special controller to operate it.

One of the most popular choices for MS users is the Inovate LC1 which includes the sensors itself and a compact controller. This is very cheap as wideband units go, but obvioulsy quite a bit more expensive than a narrow band unit. However, with the current weak dollar now is the time to buy!

Exactly what Mike said.....

Also Techedge is supported by MS - But either way, go for a wideband.....

Innovate LC-1 is what I use with MS. A guy called Bill Shurvington sells them in the UK for about £135, or as said above see what you can get one from the States for.

A wideband sensor and controller are absolutely essential to have any chance of getting a half decent map with Megasquirt - they are highly recomended!

That's a very good price really. If you ordered it from the US and customs decided to check it you'd probably pay somewhat more than that with tax etc.

Depends on if you want to use dinosaur technology
