Will it be a winter camp lol?
Thanks RutlandRover...
Just noticed it's David's P38 lol
I like the 1mm disks for cutting bolts and thin bar, need to buy more as local suppliers have been out of stock for a while. Much more likely to break up if any sideways force is applied than thicker ones but wouldn't want to see them banned.
Awww... doesn't work if you click on the link (does for me)? Bugger, that's taken the spontaneity out of it even if I get it working then!
10mm headed nuts usually have 6mm thread with 1mm pitch (standard M6) but vehicle bolts aren't always standard... Gilbert would be far more likely to know what nut you need. If you have a bit of the old bolt left (which you cut) you could try cleaning up the end of it's threads and if you have any generic 10mm nuts around (which would be very likely to be standard M6) and they screw onto your bolt you'll know you just need an M6 nut with a similar flange.
I sometimes do a bit of mild grinding but don't often dance and definitely don't go on grindr...
Daring types use angle grinders without the guard attached to allow getting into tighter spaces but some of us have scars on arms, indentations in thumbs and bits of metal burned into scalps that didn't used to be there before using an angle grinder.
The 1mm cutting disks are great for cutting but while you can use a 2/3 mm disk for a bit of very mild grinding (and I know it shouldn't really be done with a 2 or 3mm disk), don't try even mild grinding with a 1mm disk lol.
I now look at it like this... It was a bad call by the RAC man to have me continue trying to pull the caravan up Bodmin Moor (grr!) but I can kind of see his predicament and it was also a bad call from me to agree to do it. He'd probably had umpteen self proclaimed mechanics self diagnosing none-issues over the preceding weeks and sent many on their merry way after their engine had cooled down etc. The first guy the AA sent to me was a great old bloke, said he was semi retired but the AA was paying his fees for him to stop in his own caravan in mid-Cornwall so they could send him to peak season call-outs such as mine. This bloke turned up, asked me for the story in which I explained the cat problem and told him the engine had seized, he took in what I'd said, looked me up and down and didn't even bother opening the bonnet before apologising that AA had sent him in a van and he'd have to call for re-reinforcements to get my car home. I said I didn't mind as I'd be enjoying breakfast in the pub on the beach over the road ;-) He told me about in his early days as an AA mechanic (which must have been 40 years ago) he had a Viva which were known to have a common problem of dizzy drive gears breaking up, he self diagnosed his problem and told AA staff but they still sent a little van to try and fix the problem on his drive..... at a time when his wife had begun labour with his first child and he intended to drive her to hospital. A good chat and I asked him if he fancied breakfast but he had stuff to do on works time.

'Just to let you guys know that I also contacted Damian about taking on the hosting, maintenance and support of the forum - it certainly is too good a resource to let it die.
My primary connection with the world of LPG is that I developed the FillLPG Android application (not the website, just the app) - and am currently planning a new release which will include an iOS version.
Anyway - I'm not an installer, but I am an IT professional so I'm willing and able to take the site on from a technical standpoint. What I would not be able to do is moderate the site - I have neither the time nor the insight to do so.
The offer is there but if someone else is better suited to take it on then I'm happy to stand back'.
I keep getting calls from claims companies who'd have me claim the fees I've paid Barclays for this 'enhanced' or whatever account. I've never used their travel insurance or mobile phone insurance but I have used the RAC a few times. I haven't taken any claims firms up on it because I went into the agreement with eyes open, I;m not a 'claims culture' type person anyway, and I did wonder if Barclays might close my account (which I use a lot for business) if I claimed which would be quite a hassle... But if I find there was small print which said the RAC cover was limited I might take them up on it. The first RAC guy was OK, we didn't fall out or anything but I got the full impression he didn't really believe the problems with the car and would in any case rather fob me off so he could get onto another job. He also told me we were on the top of Bodmin Moor so it was all downhill to Newquay when actually there were still the steepest hills to go up. If we'd gone with my suggestion in the first place or if it really was all downhill from there to Newquay my engine probably wouldn't be shafted now... but I know there are different ways of looking at it.
That's interesting Bri, I'll look into this thanks but I suspect you're right again on it being due to being covered through the bank.
Very easy access now, it's only when it gets overgrown that access gets bad but I generally cut it back every year using a petrol brush cutter. This year just after I'd cut it back a council hedge-trimmer tractor came past cutting hedges along Mill Lane, I flagged him down and asked if he'd come down the drive and cut the spruce way back if I paid him, he cut the trees, spruce and everything really way back. Every year I have around half a dozen large American RV's, half a dozen vehicle transporters and a few limos come down and this year it's been particularly easy for them. Just done a Hummer limo that had more ground clearance than most limo's but 'normal' limos don't have a problem either.
Yeh was more fun than that Bri.
It arrived 11pm last night.
A very easy way to get perfect atomisation, new injectors better emissions, lower running costs and easy fuel mapping is to convert to LPG ;-)
If you really want more power, realistically you're looking at changing engine hardware parts and have to bear in mind that engine power mods usually involve compromises i.e. more power at the top end at the expense of torque at the bottom end.
Been back down Cornwall and the Elgrand got loaded on an AA recovery truck yesterday. It can take 48 hours for an unaccompanied vehicle to get home, I'm back home but the Elgrand isn't here yet. No rush, I still don't have an engine to put in it.
As Gilbertd implied, if your ECU is old enough to be not fully sequential then switching one channel (would expect cyl 1 or cyl 5 in LPG software) back to petrol has the potential to switch the whole bank back to petrol... It shouldn't happen but can happen and is more likely to happen when a recent version of software is used with an older ECU, the ECU may not properly support all the features the software seems to offer. For similar reasons it can happen if 'anticipate the injection sequence' is ticked in software Could also potentially happen if the engine is already struggling to idle properly on one bank and you switch a cylinder back to petrol on the other bank if on the other bank the injection sequence has incorrect routing (i.e. LPG injector channel numbers don't match petrol injector channel numbers) such as when an installer has hard wired an injection sequence advance.
I did miss the fact it's a Disco 1, and as you've said this will mean it runs batch fired injectors.
This will mean the installer is less likely to have hard-wired an injection sequence advance if they did correctly set injection type as group in software / but it they incorrectly set injection type as sequential they might still have tried it. Most of the other aspects I mentioned above are still relevant with the engine being batch fired, in fact type of injectors fitted is more critical on a batch fired engine because of the shorter (but twice as often) injection pulses , also affects the shape of the map (usually a greater difference in multiplier between idle and high loads).
On the older AEB systems it's usually possible to get good results setting sequential injection type when the engine runs group injection - when the rpm wire is used some of the old AEB LPG ECUs just read the total pulse time of the front petrol injector on each cylinder bank between X ignition pulses and then they will actually drive all the LPG injectors sequentially (just spaces each cylinder dose of fuel according to rpm) even on a group petrol injection engine. It shouldn't be set like that really but good results can be had... it means LPG injectors last longer (only doing half as many pulses) and don't have to be as quick to open/close than if the correct (group) setting is used (can get away with less decent injectors - which is why some installers found that setting sequential on a group engine got better results than setting group). Setting sequential on a group engine still opens up all the ways that the installer might play around with injection sequence such as hard-wiring an injection sequence advance.
If it's always been OK and now it isn't then it won't be calibration that's the problem unless the ECU has forgotten calibration settings (by which point the ECU is more or less broken really), it will be due to a hardware problem with either the LPG system or the vehicle (lambdas usually).
You probably shouldn't be at the point of attempting to calibrate yet but If you do try to calibrate....
If it's Etagas it will take forever to calibrate unless you drive it to keep rpms within the certain ranges until all the range boxes are learned. It would be no good trying to hold rpms in the range boxes while not driving as there wouldn't be enough engine load and all the learning/autocal done would be wrong.
Since you say you have the ability to switch individual cylinders back to petrol it would seem you have a sequential system.
If you have a sequential system don't try to get ginj = pinj, do try to get pinj to remain close to unchanged when you switch between fuels.
It doesn't much matter on a P38 if ginj is 1.2 or 1.5 or even 0.8 x pinj at idle. The at idle multiplier should depend on spec of components fitted and pressure settings... If you have Matrix injectors I might expect multiplier of 1.1 at idle falling to 1 at flat out loads, if you have some of the worst performing Tartarini injectors fitted I might expect mutliplier of 1.2 at idle to 1 at high loads, these figures are only so close (1.1 / 1.2) because the P38 idles with 4ms pinj anyway (and 4 x 1.2 = 4.8 which is an easy minimum pulse duration for nearly any LPG injector). But really, knowing how half of P38s were/are setup by installers of the day I might expect anything between 0.7 and 1.7... but it should still work OK.
You should never see ginj remain the same multiple of pinj across the load range, ginj should become a lower multiple of pinj as load increases (at anything much above low loads at least) and for best results from any components you have fitted ginj should be close to pinj at high loads when at the same time mixture at high loads is correct. Or calibration is wrong, or you have a pressure sensor problem.
Popping from the exhaust could have various causes including implications from an overall too lean or too rich mixture or a dodgy ignition system, but if you only get popping from the exhaust when you switch a specific cylinder back to petrol it could be that your gas injector plugs are on the wrong gas injectors... and in that case they might even have been put on the wrong injectors intentionally by an installer who was trying to hardwire an 'advanced injection sequence' (on something as simple as a P38 this would usually have been because they'd fitted a setup with incorrect combination of nozzle size and pressure).
@Dhadara, what did you calibrate to .45? The best way to see how well an engine is running on a certain fuel is to check inlet manifold vacuum readings at the same time as ensuring lambda is correct, a happy engine will draw more vacuum, there shouldn't be any difference between petrol vacuum and LPG vacuum. You can get more vacuum with a rich mixture but remember we covered correct mixture with lambda and we're looking for most vacuum with correct mixture.
I did register with the auction site in the PM but it eventually sold for too much really. Would have been well worth it as a repairable Elgrand or maybe even just for parts if I were to dismantle it and sell parts but I don't have the time... I might just buy an engine to fit in mine and let someone else profit from dismantling while I'm doing LPG stuff.
Became a member of AA with all the bells and whistles today. Clarified that they'll pick up a vehicle and deliver to where I say in the event I'm on holiday with the caravan and don't want to come home with the vehicle lol... £14 a month and can cancel with a months notice ;-) Plan is to nip to Cornwall on Wednesday and have a bit of a break in the caravan for a few days, will probably leave the caravan there when I come home and nip down again before the end of summer... but the Elgrand will be home soon lol.
@Giilbertd Did you hear from Richard?
