As I said you have no way of telling - an exhaust gas analyzer is only good for basic tuning or MOT testing.it simply cant respond quickly enough to be any good for things like sudden load or throttle opening.
News flash, neither can the EFI sensors the Lambda probes are monumentally slow this is why normally the lookup tables in the map are set to overfuel like mad on acceleration
Even with a rolling road it is limited in its use.
I never made any comments about Bosch L or K jetronic.
err so you did not type this then?
The 14cux injection system is fine - the first decent attempt at fueling a Rover v8 after SU's.
would you mind telling us what fuel system was between these two? AFIK it was Bosch L-jetronic, with lucas badges stuck over the Bosch marknings.

Cooker ring gas systems are for forklifts.
only if you haven't the first clue how to make them work

take a look at the list of cars below, the only one to have had HGF is the SD1 (which had twin SUs and the 3.5)

You are basing all your statements on a single collection of cars - sorry thats not representative.
Lambda probes monumentally slow,I dont think so,you need to either read a bit or do some real research under the bonnet of vehicles - not just one or two.And bring yourself into the world of UEGO's.
Like alot of other car makers in the late 80's,early 90's LR used a mix and match of components.The Cux system had allsorts of bits and pieces in it,but I dont remember anything much of it being the same as the GM stuff I looked after that ran L jetronic - and K was mechanical anyway.
Sorry,but an exhaust gas analyzer just does not respond quickly enough to be of real use.Even the classic racing people are now using UEGO's to tune engines to make more power now than they ever did.I have a customer wanting to use them on an Alvis speed 25 six to be sure he is getting the best out of his SU's.
As an aside I see that elswhere on this bit of the forum you were asking about replacing corroded brake pipes.And then you ask about bleeding dual circuit brakes,with this level of knowledge I wonder why you are trying to champion the use of the wrong equipment to tune an engine fitted with an LPG system that can only do a weak job in fuelling an engine that needs all the help it can get.

Saves me typing
 
whats a UEGO?
Bit of a silly name really,Universal Exhaust Gas Oxygen sensor. Now becoming commonplace in petrol and diesel applications.Often have 5 or 6 wires compared to the older type sensors having 1,2,3 or 4 wires.
They work in a totally different way having a cell in them that uses a pump to keep the inside of the cell at lambda varying the current to the pump to control it.They are true wideband sensors that can respond almost as quickly as each firing event passes its pulse out of the exhaust port.They can measure Air/fuel from about 9.5/1 to 18.5 /1 - a long way either side of lambda.With the right control gear they can control fuel trims, run air/fuel gauges or provide info to data loggers.
They have rapidly become the tuning tool of choice because they dont cost much,and can give live data in real world situations.
I fitted a pair on a 3.9 Classic to use for tuning its LPG,very interesting results.Made me realise how accurate 14CUX is even on a car with 100k on it.Also how inaccurate multipoint LPG systems are and how they go off tune after a good years running.
Have a look here; Universal Digital Tuning Products and Tuning Tools from Innovate Motorsports
 
cool.

so no use on my classic with twin SU's even with lpg lol :p
It would be the very best way to tune it - like I said the classic racing people are getting more power now than they ever did using UEGO's. On petrol about 12.5/1 gives max power,LPG is slightly different,cant remember off the top of me head.
The nice thing about them is all you need to do is weld a boss in the downpipe,which you can put a plug in when you dont need it or sell the car etc.
 
You mount the Uego into the downpipe then connect it to either a hand held unit or dash mounted gauge,calibrate the sensor and you are away - seeing air/fuel ratio in live time.It was using this kit that made me realise how good 14CUX,Gems and Motronic is - and how hard it is to get LPG to do anything like as well.(Esp for more than one journey.)
 
whats i run...buy from states and save a few bucks..

re lpg...spent a good few hours down a quite road with my laptop next to me plugged into lpg ecu while altering setup...while reading wide band afm..i use digital gauge in dash.

massive difference now...virtually as good as petrol now,well worth the investment,everyone should have one..i bought for supercharger install,seting up fueling etc..
