Hi All,
Just purchased the Radical kit for closed loop Lambda Control for my RSX. Before I run the cable through the engine bay I thought I would ask if anyone else had already done it, and to see how you dealt with the first 16" or so of cable routing (to keep it away from the hot exhaust and make it tidy). Probably doesn't help that the O2 bung is in the top of the header junction and that the first 8" of cable before the plug is pretty stiff, but I guess that's the best location for the probe)
Any pictures might help...
Rod, I don't have an answer but I noticed recently that one of the sensor cables which is close to the exhaust is shrouded with a loose heat shield tubing to protect against radiant heat from the exhaust.
As DavidF said Rod, get some heat protection on there.
Unfortunately it is bending it back over itself and cable tying to the chassis leaving as much as you can from the exhaust.
As you say a port in the side would be much nicer!
@rjbender Do you have a link to this product? I'd like to add one myself and was going the stand alone route, but would love to see the data reflected in the aim logs
@smoothcriminal .. G’day Mr Criminal…
See below for the details and part numbers… this is for the Radical ‘Kit’…. And as you can see on the invoice this was meant to include a ‘remote setting up fee’. A word of warning on this… I struggled to get their attention after spending the $1000 (AUD not USD … equal to around $600 USD)… and after several months of waiting, finally got them to hook up to the ECU remotely… but after about an hour they couldn’t get the ECU to communicate with the lambda sensor… and said they needed to check with Life (the ECU manufacturer)…. And I have heard zero since that day….
At the end of all this, having wasted $1000 I wish I had proceeded with my original plan and gone ahead with a ‘standalone’ AiM Lambda sensor setup…. Connected directly into the AiM Dash/Data system. While this would not have given my ECU a chance to ‘trim’ the fuel injectors as well as log Lambda in the ECU data… it probably would have worked to allow me to see what the Lambda was doing!!…. What I have now is an expensive ‘kit’ that hasn’t worked.
I’ve since purchased an SR3 XX and will probably try and get them to set this ‘kit’ up on that engine… hopefully this time it won’t take months and will actually result in a sensor that works…
Sorry if this post seems downbeat… but my Radical experience (including what should have been an exciting ‘once in a lifetime’ purchase experience of a brand new SR3 XX versus the disappointment as to what was delivered all the way to Australia has got the best of me lately….)

What is the (potential) benefit of a lambda sensor on a Radical SR3?
Sometime next year I am planning on ripping out all the wiring from SR3 and installing a Haltech Elite ecu with the wideband O2 feedback.
This will be far superior to any "factory" ecu for expansion and engine safety. Far supeior to what I have anyways. 🙂
@davidf The lambada sensor would keep the engine from running too rich on full/heavy throttle and would not only get a few extra ponies out of the egine but would also fight misfires from any quick on/off throttle situations from unburnt fuel.
