thanks

I think Dave meant perpendicular, not parallel. I've read somewhere that about a metre is considered the optimum distance from the exhaust valves. I've just managed to squeeze one infront of the selector box (my car is GRP, not standard Mini). I reckon this would be better as the pipe is still offset to go around the selector. I'll be cutting a hole so the sensor can be unscrewed through the floor, the cable would be a very tight fit anyway without it.

My thought with sensing just one side of an LCB is you could monitor the most critical pair of cylinders, I'm not sure which that would be, the inners? I guess the downside is something could happen to the other pair and you wouldn't know.


I wonder if you could build a simple comparitor circuit so you could use a lean lambda value to interrupt a temperature sensor signal to the MJ? You might manage to use the MJ auxilliary input for engine warm up as well then, by setting one of the bins to zero or five faults and making that the output from your comparitor.


The sensor bosses are plentiful on Ebay, either as weld ons or in a short length of pipe you could
U clamp in.

Justto follow what morley has said Just bought one of these gauge kits rage performance in the states. Got it within 2 days Fedex. Works well. Fits the existing lambda sensor hole if you already have one that is.

mine arrived after 2 days fedex , incredible!

bought an AEM for my mini years ago and haven't been for a rolling road tune up since, saved myself a fortune in the long run by profiling the needle myself and monitoring with the wideband.

 

Blasting in from the past but the info is still valid...

 

I've just installed an AEM wideband AFR gauge, we don't have a rolling road here so I figure this is about the next best thing.

 I'm wondering if people are using these with a logger for TPS, MAP, RPM or even SPLOD etc?  If so, which logger, bearing in mind the AEM outputs 0-5v?  I don't want to spend a fortune on a logger but something that could compare the AFR and at least one other.  Oh, and a long shot...  If I could make it output directly to a Mac lappy would be best of all...

Anyone?

I just made a mental note each time

That's what I'm doing at the mo' and I'm getting dialled in slowly.  It'd be nice to be able to log a comparison though.

S'pose the cheapest would be to just vid your gauge with a timestamp.

er... Well the price is OK and it'll run on a Mac

I'm getting close on my mixture now after days of averaging out the numbers on the gauge, I'm getting close now, I've established that I need a needle that doesn't exist
