evening guys,

i am looking around at the moment for a lambda sensor but know absolutely nothing about them, all i know really is that you can get narrow band and wide band? but what is the difference?

in typing it in google it comes up with 'Inovation Lc1 Wide Band Lambda Sensor' and it is mentioned in a lot of posts.

what are peoples recommendations for lambda sensors and how much do they cost?

What do you want to use it for? It may have some bearing as to which type you need.

doing pinto conversion from carbs to TB's with megasquirt-edis and need lambda sensor as an input for the ecu. do you need a lamca sensor to aid tuning of the engine?

Narrowband tells you whether you are richer or leaner than 14.7:1 air/fuel ratio but not by how much. Wideband tells you the exact AFR you a running at all times.

NB is fine for the ECU input once the engine is tuned, but wideband is pretty much essential to make on-road tuning of the maps easy.

i have been looking at the wideband lambda sensor by Techedge, the 2J1 model sold here by trigger-wheels.com

trigger wheels linky

the reviews that ive been reading say that its a very goos system for the 'average jow' who wants to tune for fast road use.

any opinions ?

I just bought a 2J1. It looks a neat piece if kit. It comes with bugger all instructions, but the website is fairly extensive!

I like the idea of the JAW, but I couldn't find as much info as the wbo2.com site offers.

That JAW looks spot on... going to order one and have a play!

The JAW promises to be useful, and I've just finished soldering up the main board and display. The board and components seem to be of decent quality, although I thought some the tracks were unnecessarily thin. I hope to be trying it out on the bench tonight.

It is worth bearing in mind where it comes from though - builders seem to get reasonable support, but it doesn't match the Megasquirt and Megajolt sites, and the 'company' appears to be very much a one-man-band.

However the designer, Adrian To, does seem to have a number of very useful products coming along soon. There's a new version of JAW imminent (it might be worth waiting a little while to get the new one) and there will soon be a tiny wideband sensor board that will be perfect for linking in to other systems such as Megajolt.

On balance, it's good value for money despite some (minor) reservations.

Correction to my post above - Chris @ www.trigger-wheels.com emailed me the instuctions today. So big thanks to him. Looks like a good locost option for those who are scared of soldering irons!
