ok - this may be a stupid question but is it possible to wire in a lambda sensor and stoich guage on a NON EFi car? does it just require a battery connection (what voltage? 12?) and away we go?? has anyone done this? and are lambda sensors related to engine size in any way? or will any one fit anyone (thread permitting) the reason for asking is i am currently building a exhaust manifold and could also use the oportunity to includ a place for a sensor as it would apear to be a good diognostic / setup peice of kit for acheiving stoichiometry in my engine with less time on the costly rolling road, (it is only 1 SU to setup afterall) would it not?

why would you want to do this ? long and complex......just go for an engine conversion if your wanting the lambda there
another product brought to us by Volvo back in the late '70's as a way to reduce emmision levels over in california, now anything built in the last 5 years is guranteed to have a minimum of 1

as i said before, would it not be a good way to acheive a stoichiometric combustion? without expensive equipment or am i barking up the wrong tree?. could build th above setup for not more than £25 -alot less than a rollingoad setup - though not as accurate. i think alpha do a setup already but its lotsa money.

to measure anything meaning full with a view to setting the car up you would need a wide band lambda sensor which are a few hundred quid alone. If you were running mappable injection/ignition it would be worth while as you could have a mate adjust the map on the fly under differrent load/rpm conditions, but for a single SU go old school get a colourtune and play it buy ear

I looked into this a while ago. There were some kits on ebay, the actual pcb and componenets were cheap but the sensor put the price up too far, I think they used a honda sensor. This aussie page might help: www.techedge.com.au/vehicle/wbo2/default.htmThere used to be a good page on a diy set up but it is currently off line. I definately think they are a good idea as you can monitor the car in a real world situation but whether its worth the money I'm not sure.

Bill Shurvinton (Google for his email address - it's out there somewhere) sells MegaSquirt kits and systems. He also sells TechEdge and Innovate Motorsports wideband O2 systems. My Innovate cost me about £130 for the system (sensor, controller, ferrule, cables, instructions, etc.) - not too bad and it should work well with my MS on the Imp. ;D WBO2 sensor does not vary with engine size. Also it is heated by the WB controller and so does not need to be placed where it will be at a specific temperature, like lambda does. I think you can now get WBO2 gauges for real time readings but you can also log data using a laptop. I'm not sure whether you'd have to write your own application to do that. No software came with my Innovate system. However, MS allows logging, including WBO2. Bill also posts on the MS forum. I'm

many thanks for the replys - it was a nice idea but not cost affective. didnt realise there where more than one kind of lambda sensor either. cheers neways. am tempted by MS... oneday....

Easiest and best way to set up a carb unless you have your own rolling road at home
