Have to confess I've not done much because the hot weather makes any work outdoors on my dirt track pretty awful. So I have been putting up with my 'lack of power' problem. I have bored you with the signs but if it helps then I should have said that this lack of power is very affected by the ambient heat and therefore the heat under bonnet. I start up, engine cold - not too bad, drives away ok, after hours down on the coast shopping, engine really hot - outdoors it is around 40 degree mark (bonnet too hot to keep hand on)- temp gauge shows normal - drive up the hill to come home and the engine hardly makes it in low range - seems like a fuel shortage to me - jump on throttle no response. Sometimes engine has just stalled whilst idling at traffic lights. On level, or downhill not under load picks up more like normal. Sorry to go on about it but if it is a fuel problem what could cause this - it is same for Petrol and LPG.

Despite thinking that I am 'with it' I find that I'm forgetting where and what things are - so much stuff around ! But, I had a copy of RAVE that I think Gilbert may have put me on to. I lost this when one of my drives went down and now have downloaded a good English version that I have also saved on a CD - about 400 mb. This one seems to work very well and if it helps I could upload it to WE file transfer - with your email as the recipient - it is only active for a week or so - message me if you are interested. chris@seebafilms.co.uk (or are we breaking any rules)

Thanks Gilbert. Does the Nanocom do all the settings that one would need or are there things it can't do ? I looked on google about gearbox ecu stuff and came up with Landyzone link where they had similar gear change but opposite to my problems and he traced it to faulty wires.connections into ECU see https://www.landyzone.co.uk/land-rover/p38-keeps-changing-down-gear.66979/

Nothing I see in the Storey EAS for Gearbox under Gems - could it be in BECM ? You may remember that I went through the rat problem - LPG stopped and I drove for some way on petrol when they ate wires until I realised and repaired all I could. Been driving on LPG apart from start up for years. The system probably doesn't know its arse from its elbow !
Chris10 suggests checking the speed connector from the gearbox which is under the Coolant tank and under which the rats made their home - wires on the lunch menu ! It has improved today as I said above out of all recognition as a result of all your hints - but it seems to me that the reluctance to not always change down under load could be because it is not getting some sensor signal ? So still looking - been hot today !

Petrol - 'cos I was paying attention and understood it had to be 'set up' on petrol as you explained. But how come it doesn't 'readjust' when it goes back onto LPG ?

Well, have to report some results ! Filled with about 10 galls - not used to seeing how high the needle was on gauge - reset adaptives and drove 12 miles or so along motorway and lo and behold, noticed a big difference - much more as it should be !! Still slow to change down under load at times - had to use sport mode a few times to keep up the speed but overall a 100 percent better. So overall much improved but there is still a tendency not to want to change down when it should. It is as if the ECU is not getting some info about speeds and demands - the only thing not yet replaced is the Crankshaft speed sensor - does this give the RPM that shows on the dashboard because if so that still shows as you would expect. But I'm grateful to all as we are at least on the right track Done about 25 miles of varied motoring - how long might it need to make its mind up and when do I judge that all the adaptives have done their best and still need to look further ?

Thanks both - tomorrow I'm raiding the bank to buy 10 gallons of real petrol - will be the most put in, in one go, for years !! Then I'll do a reset and drive to Caleta along motorway and other roads to fill up with LPG at 70 cents a litre and hope that it does a self adjust !!

Thanks Gilbert but I don't think my Storey EAS shows things like fuel trims or values - still getting used to it but as far as I can see it seems only to show faults (Code number), clear faults and reset adaptives. The suspension part allows readings and settings in more detail.

Well I'm in good hands with Brian and Gilbert - just as a curious boy at back of class - tell me - If fuel is low and I do the 'reset adaptives' with my Storey EAS are you saying that the ECU says to itself 'Fuel low - ignore Adaptive reset' and therefore does not carry out any reset ? I'm sure that is a tricky one for you - expect you know though !

I will be an expert by the time all this is done - can't believe all this knowledge is always in the official garages !

Yes Brian - what you say makes sense - Thanks for explaining the reasons - I've fallen into bad habits up my mountain but it was perfect until about a year ago. Will just have to do my homework and try and get it back as before.

As usual Gilbert you have filled in some gaps. And I seem destined to do/have everything against the system. Of course my tank is always only a quarter or mostly less !! Why on earth do they make that a factor on the adaptives ?? odd mixture running you say ! Anyway that will be the next task - fill the tank more ! I'm pleased you noted that closed throttle down the mountain could be a problem - that seems logical. Well this afternoon I reset and then drove around the scenic/ring route (levelish but ups and downs) for about 10 miles and although not solved it is slightly better. What I don't understand though is if you do a reset, surely before the adaptives come into it, it should perform like driven out of the factory ?? or do they put them through a sort of adaptive run through before we get them ? The gear change down is still very reluctant !

Thinking more about it - since ALL my journeys start with a 5 mile descent is it possible over the years that this has affected the settings in a way that adaptives now don't adjust ? And even if I do a reset the start is the same 5 mile downhill. I can make a 7 mile journey on the same level to Frigiliana if I have to but usually only do this once a year. Perhaps I should do that after a reset ?

By the way - sorry to go on about this - but as far as adaptives are concerned my journey starts all downhill from about 1000 feet for 5 miles. The engine hardly heats up in winter and uses little fuel downhill. Potter around in town on level - RPM hardly ever above 2000 then return up the mountain. I think the adaptives must have had a bit of a job here over the years and still do? My good old Willys jeep never had to put up with all that adaptive nonsense and just went up and down any hill !

Posted this to Chris already but added here for Gilbert !

The EAS software started as a free prog that Storey developed just for the Suspension - it was wonderful - got me through all the suspension rebuilds and fixes - but it was only the suspension. Later on he worked on a later version which now covers the whole diagnostic thing (without giving individual voltage readings) shows and resets faults and allows reset of adaptives - but he kept the same letters EAS for the prog so I don't think the early people like me caught on to the fact that it was more than just EAS ! Cost about £150 download and comes with special OBD lead to USB.
It shows faults with my ABS which I have not got round to - something about air gaps that Gilbert says you tap in with hammer- and there are some odd things about HEVAC but the aircon seems ok. No faults show on GEMS. I cleaned the MAF yesterday carefully with meth spirit and the outside was filthy as if it had been sprayed with a varnish or some sticky compound. And there is definitely an improvement but the simple fact is that as one approaches a hill or load with accelerator in steady position it does not trigger an automatic change down as you would expect and just labours slower and slower. I trigger a gear change with the Sport button or kicking down accelerator. At other times it accelerates for a bit as you expect and yes it revs up in neutral as normal to top rpm. It seems related to a sensor and I have a nice new CPS waiting to go on or under - and have swapped the TPS back and forth with no difference-(looks ok on ohmmeter) Perhaps I should check the plugs and cables (oily and a bit battered x country ?) that go into the gearbox underneath.
TPS is very hard to find at a decent or any price it seems. Yes I should check TPS connections - plug is ok but couldn't face trying to trace the cable - goes into a loom dosn't it - can I put a meter on anything and if so what should one expect ?
Don't know about poodles up the mountain but yesterday dogs were barking - took one up the hill for a walk and saw these brown ears, brown nose and beady brown eyes looking at us through the bushes - realised it was a wild boar that turned and ran - a few seconds later further down it came into view crossing the track followed by TEN others .............running off like mad. In my ten to fifteen years here I have only ever seen one at a time and only about once a year !

I did a reset - have not cleaned the MAF yet - but how long should one run on petrol for the adaptives to set before switching to LPG ?

No - we have not froze - just the opposite - outside air temp around 40 degrees in afternoon - not conducive to getting under car and in the cool morning I'm too tired ! Changed the MAF - slight difference in performance but still have the lack of power/reluctance to change down when it should do. I can force a gear change down by tapping pedal twice but it does not do it as necessary and normal. Just content to limp down to the shops for the wine and dog food and will wait for cooler weather which usually comes at beginning of September.
What signal is the ecu not getting to initiate gear change and increase revs ?????

By the way, travelling the roads across Spain (and France in parts) is a delight - very little traffic except by the places like Malaga and Marbella. In fact on the drive down from UK via Madrid (which you bypass by motorway) it is quite an occasion to see another car in your mirror or ahead - for mile after mile there is no other traffic to see - driving as it used to be !

That is really interesting Gilbert (doesn't he come up with some surprising stuff) Knowing the rare state of LPG in Spain I think it will be a long time before they get round to any plans. Having said that, there is a growing number of taxis and ambulances (mainly those near big towns with LPG) It has not really caught on with the average Spanish car driver and as I explained before is only recognised recently on the documentation for MOT if done by one of the few approved installers with an 'approved' set of parts !

I never did this - do you get cheaper road tax ?
