There's a good clean looking Prins system with a King ecu on ebay. £350

Huh? It's a King system then. A Prins will have the Prins ECU and reducer (along with the dodgy external injector emulator that most of them use) and Keihin injectors. A king system will have a King ECU with whatever reducer and injectors the original installer chose to fit.

But a secondhand kit is worth at best, half of that when you can buy brand new for less http://www.lpgshop.co.uk/8cyl-mini-kit-king-obd-omvl-hp-omvl-rail/

If it's this one https://www.ebay.co.uk/itm/Range-Rover-P38-4-0-4-6-Thor-Multi-Point-LPG-Gas-Kit-Full-Set-Up-99-02-Prins/302412202111, I'm not sure where Prins came from. It's a King ECU and OMVL injectors but I can't make out what the reducer is from the pictures but it looks like it may well be OMVL too. So nowt Prins about it at all. Although it is the same seller that sent me different coloured seats to the ones shown in the picture on the ad and sent you an Immaculate bonnet that wasn't......

Say's Prins right there in the ebay link mate!

Anyroad, yes. it does appear to be the seller that hasn't got quite the keen eye that his listings sometimes advertise. Perhaps the inclusion of Prins in his listing title confirms that. lol

Avoid Prins and BRC for the same reasons your Landi isn't too clever. Very limited injector options (only the ones that come with it) and, limited software availability (if at all in the case of Prins).

Agreed, I wouldn't recommend either of those especially as a DIY install.

Just to add to that - I expect BRC software is now easily available since Tinleytech are the new BRC supplier and won't be as fussy as the old BRC GB used to be... In the days of BRCGB I believe I was the only installer not to have gone through their 'training' (which BRC installers paid £1000 for) who BRC GB would supply and allow access to their software downloads.. probably because they knew I could sort BRC problems when their local BRC installers couldn't ;-) I know they had a board meeting in which they decided to allow me access even though I hadn't paid lol. Out of the two (BRC / Prins) from a calibration point of view it is far simpler to switch a Prins system from one model vehicle to another provided the Keihin injectors are a good match for the engine spec (BRC a bit more forgiving in this because can work at a wider range of pressures than Prins). I could give you Prins VSI1 software and a valid user key (necessary to make any adjustments) or any of the BRC software (except the latest 'BRC calibration tool', which I have, but which needs a unique activation key which tallies with some unique aspect of each laptop such as I expect it's mac address, so only BRC or TTech can provide the activation key). Both Prins and BRC systems use their own unique interface cables, you can buy clones but they don't always work. For example there are about 7 variants of BRC, the proper BRC cable works on all variants, the clones are usually variant specific. BRC can be a minefield to set up, most variants don't use a runtime vac sensor but need an installer spec vac sensor for initial calibration, some variants use 3 files to setup (firmware, methodolgy and calibration) to suit the vehicle for aspects such as extra injection filtering. There's BRC Sequent, Sequent24, Sequent24MY07, Sequent56, Sequent56MY07, Plug n Drive, Sequent32... Each uses different software
, is setup differently, some are even wired to the car differently (e.g. Seq24 preMY07 cuts the common positive to petrol injectors, no petrol injector breaks as such, just one wire to each petrol injector.. and it's incapable of true sequential operation because it batch fires LPG injectors in blocks of 2).

No Prins bits there lol... Reducer looks like a Tomasetto model, I'd guess Arctic as gas enters from the side unlike Alaska and it doesn't have a gold coloured rear unlike Antarctic. Would expect an Arctic to struggle to flow enough for a P38.

Thanks guys, I’ll avoid them for sure, also as I messaged him asking if it was possible to purchase the engine loom as well, was told he would sell me a loom to wire it into ,, in my words, he can stick it where the sun don’t shine 😁. He’s obviously just cut every cable to remove it.
I’ll try some injectors and see if mine improves, if not I’ll have to save some pennies and send it upto Simon in the new year to have a fresh install

It wouldn't be much of a problem to wire either of those systems in correctly, it could be a problem to get them running properly after you'd wired them in correctly.

Not saying you need to buy all new stuff, that King system wouldn't be a bad bet since it comes with the tank and would also have the advantage of being similar to what most people here have and are familiar with. I'll be around on forum but when I'm not others could help you with the King system, probably not so much with BRC or Prins. So/so value considering it's second hand but the parts should be as good as new and would be a way of saving money over new.

Thanks Simon, I’ll see how the penny’s go before I decide, I’m not using the car much at the minute so it’s not to much of a hassle

Impco is an American brand, it's good quality expensive stuff but they only make mixer systems. Most useful for converting big carb or big throttle body injection engines like old Yank V8s. Depending on the type, unlike most European mixer systems Impco often have serviceable parts inside the mixer itself such as diaphragms (in contrast most mixers are effectively just a machined metal orifice, no moving parts). Imported vehicles LPG converted in the US using Impco gear often have US brand closed loop electronics fitted which usually goes wrong before the actual Impco stuff, if such closed electronics goes wrong it's best to replace that with European spec stuff where possible (not possible with all types of Impco). We don't see many vehicles converted in Europe using Impco gear with closed loop electronics fitted.

oh goody! i do so love having simple stuff to fix!
it is a huge system in size, which looks like you could fit it on a truck. worked well for the last three years, but now not so much.
will see if there are parts inside it.

Here you go, all the Impco spare parts you could possibly need http://tinleytech.co.uk/shop/?pa_brand=impco&widget_search=yes or you could, as I said in the other thread, just sling the Impco and bung a single point system on instead. This http://tinleytech.co.uk/shop/lpg-kits/single-point-closed-loop-induction-system-petrol-injected/ would do the job nicely.

Of course, your third option would be to get it to Simon and see what the actual problem is, at least then if it can be saved and won't cost too much, you'll know what bits to change.

I meant to say earlier in the thread - thanks for the recommendation Richard ;-)

Ta very much, have looked on the sites, they do the parts i have. Although due to the Gov. deciding I've had a miraculous recovery, and am no longer disabled, not much I can afford, might stretch to a filter kit :-)
One day when i wake up from this nightmare, I'll fit a different system to Beastie, till then, I'll keeping stalling with the Impco.
Ta very much for the help, really good of you all.

I have had very reliable service from my ancient Zavoli GE system on Michael. Apart from needing filters and an age related leak sorted it's been pretty good..... as there are newer versions I am sure they would be as good.

Well, Zavoli ECU's are fairly generic AEB ECU's so no problem with reliability there, Zavoli reducers are OK, Zavoli own brand injectors not great but sometimes they were fitted with 'Matrix' injectors which really are good.

Mines got two black things, one on each rocker cover, then the manifold was drilled and tapped... All done in Malaysia where it first lived. Must admit the few things I've done have all been pretty simple.

If they look like this (but with 4 thin pipes coming out of them)

http://tinleytech.co.uk/shop/lpg-parts/matrix-xj-544-18-injector-rail-4-cylinder-black/

they are Matrix. Not cheap but damn near bomb proof and last for ever.

Mine look just like that with a Zavoli sticker on them.... no wonder I've had no issues :-)
