Simon_hill Posted January 27, 2009 Share Posted January 27, 2009 Hi All, I'm moving to Germany and it looks like I'll need a catalyst to stand a chance of registering the car there, even though it's not required in the UK. The car is a '95, originally 1.4SS (now 1.8 EU2, though running the old ECU, so largely irrelevant), which is fitted with a 4 into 1 long primary system with no catalytic converter. Assuming I buy a exhaust/cat with lambda sensor etc, was this ECU ever capable of taking a lambda sensor input (i.e. unlikely as it is, is there a socket for the lambda sensor, which the ECU would then read and magically switch to closed loop control?) If it's not that simple (I suspect not), then is there an alternative ECU from the same era, which would work (were there two specs - cat and non cat)? If not, any suggestions (apart from emerald and new exhaust with cat) Many thanks in advance, Simon Link to comment Share on other sites More sharing options...
Englishmaninwales Posted January 27, 2009 Share Posted January 27, 2009 Simon My 1994 1400ss ECU/loom has a lambda probe wiring spur with female plug. Comes out of the engine loom close to the clutch lever/belhousing. I will confim the colours of the wires. I'm pretty sure that your ECU will support the Lambda, but I expect someone with more knowledge about this will be along soon Malcolm Link to comment Share on other sites More sharing options...
Milesk Posted January 27, 2009 Share Posted January 27, 2009 I have just done exactly that to get a 1992 engine through the current SVA Although the female connector is on the loom check the wires connect to the ecu. I reiuned a cat due to me assuming Caterham must have connected them, they didn't. I can not find my old ecu diagrams - however they are on the net. My car passed the current emmissions 4 weeks ago although the engine is 1992 Hope this helps Miles Link to comment Share on other sites More sharing options...
elie boone Posted January 27, 2009 Share Posted January 27, 2009 Simon, your ECU should support the lambda probe. i have a std K series cat with exhaust, it doesn't have the front tube ( 4/1 inside engine bay ) and the rear exit tube is also missing. For free but u need to come and pick it up in Belgium. Link to comment Share on other sites More sharing options...
Simon_hill Posted January 28, 2009 Author Share Posted January 28, 2009 Cheers for the replies so far guys Sounds like it could be relatively straightforward. Will have to check the connector tonight. Might be slightly tricking seeing if the wires go into the ECU though! Miles, did the engine run any differently? Cheers again, Simon Link to comment Share on other sites More sharing options...
Mick Day Posted January 29, 2009 Share Posted January 29, 2009 Simon This may help: here. Although it mentions an Emerald ECU the pinouts on the plug are the same for the Rover ECU. As you can see it tells you the position of the pin-out & colour of the wire. Once youve identified the lambda sensor plug you can test for continuity into the ECU plug using the continuity function on your multi-meter.

Simon_hill Posted January 29, 2009 Author Share Posted January 29, 2009 Thanks Mick I'll have a go with a multimeter in the daylight tomorrow. Fingers crossed Link to comment Share on other sites More sharing options...
Nifty Posted January 29, 2009 Share Posted January 29, 2009 Simon, I have a 4-1 long primary exhaust with integral cat somewhere in my garage if you are interested. Complete system from block to tailpipe. ======================================== Keep off the straight and narrow 😬 Link to comment Share on other sites More sharing options...
Simon_hill Posted January 29, 2009 Author Share Posted January 29, 2009 Hi Nifty, Yes I would be. Have sent you a blatmail. Cheers, Simon Link to comment Share on other sites More sharing options...
Milesk Posted January 30, 2009 Share Posted January 30, 2009 Dear Simon With a standard pipe/cat and lambda sensor I was surprised how much quieter it was and yes there is a noticible difference in power Hope this helps Link to comment Share on other sites More sharing options...
