AFR information needed

Ok I have a nice afr guage which requires an innovate lc1 or lc2 controller and sensor but I I know nothing about these at al,l what I do know is that I do not need to give the ecu any information from the controller. Getting a bit :confused: now as to whats the difference between these



apart from the price :eek:

Not sure what to make of it Terry. My lc-1 full kit was around 200 brand new. I bought it from a uk company about 18 months ago. Just did a search on ebay and they are loads of money. Not sure why! The lc1 is now an old model and has been replaced by the lc2. You just need the controller and lambda.

How about this one Terry? http://www.ebay.co.uk/itm/INNOVATE-3769-LC-1-Wideband-Controler-Bosch-O2-sensor-Innovate-Dealer-/300948960029?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item4611f4b31d

What inputs does the gauge have? does it really have to be LC1/LC2?

Well Johnymd I have been reading lots of forums and they all slate the lc-1 although in its defence it rely needs wiring in top notch, no piggybacking of earths from the stereo and the like

Nice find John b I was searching lc-2 all the time going to give them a ring tomorrow

in the meantime here is the guage i'm using

Earthing is critical for all engine management/monitoring and it needs to be a fixed, stable reference point. If its shared you risk it's potential raising above zero.

Ground related problems, (loops, noise, current etc) represent some of the most difficult electrical problems to diagnose, spent many an unhappy hour chasing them on simplistic systems right up to super computers.

well just my luck the lc-2 kit has just gone down by over a grand :confused::confused::confused::confused:
