I’m pissed off with my lpg making more noise than the engine, plus bloody thing works one day, not the next, anyone got a recommendation of there system ?
I’m losing patience with it now, either it runs right or it goes into spaz mode, at the minute I’d say it’s running on 4 cylinders when on lpg, I know my mixtures are up the creek since I ran for 2 days with the wrong O2 sensors, it’s since had 2 , 70mile trips on petrol, but the mixture is still rich ( bent down to pump rear tyre, nearly choked) so I guess it needs changing by diagnostics..

is it worth sending it in to the LPG man for a potential sort out or do you think it's beyond repair? A new system will cost a couple of quid.

I'm happy with my system now... King branded AEB ECU, and Hana injectors.

If I were doing it again, I'd probably do matrix injectors.

Strangely I'm happy with my Zavoli/ AEB system with matrix injectors (those things are super quiet!).
Probably because with new reducer, new (used) ECU, all new hoses, quite a lot of wiring, soon to have new front/rear feed line, soon to have new multivalve in tank, there's not much old stuff left!
The system did last for 167000 miles before I had to replace all that stuff though and, as far as I know, the injectors are original.

Book it in with Simon. He may be a bit of a trek for you but if he can't sort it nobody can. It's going to be cheaper than the £400-500 you'd need to spend on a decent quality front end.

I know Simon can sort it out, but I need to get different injectors, mine are so noisy, sounds like a diesel when there running, iveput a lot of time and money into this one, so I want it running nice and quiet.
I have a as new set of apache ig1 injectors, but I don’t know if there compatible with my system, nor how noisy they are, although gotta be quieter than what I have at the moment

It’s not the best system ( landi renzo ) no one else seems to have, the injectors are so noisy, myengine is a very low mileage LR exchange unit, it’s soquiet, when I’m on gas the injectors are all that can be heard

I seem to remember, from the brief look at it at last years summer camp, that it's one of the Landi Renzo systems that uses an AEB controller. If it is, swapping for something like the King that has loads of different injector options would be feasible and would't require a complete re-install. Get as much info on it as you can and ask Simon if it can be made to work with the IG injectors or if you will need to change the controller too.

According to Tinleys, these matrix injectors are suitable for Landi Renzo. Same ones I have. After 150k plus miles mine just make an almost inaudible rustle!
Very not cheap though, especially as you need two of them.

Isn't Landi Renzo the baddy in the new Star Wars film?

Landi Renzo stopped having any UK distributor a few years ago - couple that to the other awkard issues you can come across (14mm gas pipe for one example, and the MED injectors if thats what its using that can cost almost as much as a new ecu and injectors would) I'd consider changing at least the ECU to give you a new one with more options for injectors etc would seem to be the sensible choice.

Those MED injectors if thats what you've got are noisy particually after being well used - the ones i had on the now dead Galaxy could be heard from inside the car tapping away.

I’ve been told that if I take the solenoids apart there’s a rubber washer which has most probably worn to nothing, hence the noise, but to be honest think I’ll have a look around and see what’s available, pipe alterations isn’t a problem, I’m just drilling a spare inlet I have to move the gas nearer the petrol injectors, I’ve adapted a set of bananas to get the pipes through, so once I’m ready to reinstall it’s all there ready.

Chris, are you installing onto a rail or into the manifold?

If it's manifold then I have a box of spares that i got with the first rangey i bought. The previous owner bought a full lpg system for spares. I have zero use for it and it's all just sat in a box in the garage. Set of 8 injectors, pipes, wiring harness (i think) 2xecu's. You can have it all if it helps. No good to me whatsoever. Think it's an AG system. Can get you pictures if you're interested.

Not sure if Landi (system) took over from the LandiRenzo systems, they're very different though.

Over the years Landi Renzo did make some unusual systems, though as Gilbert said some are compatible with the generic AEB stuff.... But don't presume just because a generic AEB type ECU (AEB2568) would fit the connector for a Landi Renzo system that it will be compatible - some may fit but use a different pinout on the connector.

There are a few very different AG systems... Some are compatible with different injectors etc, some are real oddball systems that a separate ECU / injector emulator. The latter (also known as Teleflex) you can't even calibrate because the ECUs were either mapped at the factory or the installer downloaded a map direct from AG and the maps are no longer downloadable, no manual mapping options in the ECUs at all. I have an interface and software but it's only really useful for checking pressures (or rather confirming suspicions of a broken pressure sensor). I have a few second hand spares for them including injector emulators, sensors, injectors etc, (no point fitting an ECU unless it came out of the same model car) but I wouldn't even advise playing with one that seems to be broke unless it's something very simple like a fuse lol.

Autogas2000 in Thirsk are a distributor for Landi but not for LandiRenzo. They were never great at installing but used to have decent and helpful staff (for their trade customers when they were a bigger supplier, as well as for their conversion customers)... but they seem to have gone downhill - This year I've converted over 20 Nissan Elgrands, they converted a few before me but made a real balls of them. Some of their customers took their cars back many times but all they did was plug the software in and change a few numbers in the map, eventually fobbing the customers off with a massively compromised install. I had the software for Landi but didn't realise a new version had come out in April2016 or that newer ECUs running newer firmware needed the newer software... They gave me the newer software (seemingly grudgingly) and I went on to sort out the problems on cars they'd converted... cars that basically were almost undriveable on LPG until I sorted them. So bad that is was probably just as well that they'd set them up to switch back to petrol at high loads and even switch back to petrol below 1300rpm because they were incapable of even idling properly on LPG!. One guy used to switch his car back to petrol for town driving or the engine would surge in rpm massively as it continuously switched between petrol and LPG at around 1300rpm when he was setting off (or particularly when reversing). All running nice and smoothly without using any petrol after I'd fettled them ;-) Not just a calibration problem though, they'd fitted massively undersized nozzles and the Landi reducer isn't adjustable away from 0.9 bar. Even after I'd fettled them they're still compromised a bit because of the long pipe runs they'd used and even with the bigger nozzles I drilled out the injectors won't flow enough to run totally on gas flat out high rpm - I could have sorted all the problems but customers wanted to keep costs to a minimum.. can't polish a turf.

From what was said they all started from the same company, and some sort of disagreement ended up forming Landi and Landi Renzo. So the early stuff is all the same, the later Landi and Landi Renzo may be similar but certainly not the same.

At any rate, if its a Landi Renzo he has got, its likely to be well past its best by now (look at mine that constantly sees lambda voltage of .38 even though the wire isn't connected to anything now), and given the limited choice of injectors natively supported it would be more sensible to ditch the ecu and go for a new one, giving far more choice of injectors?

You can try to polish, but you end up covered in it!

A new system it is, I’ll have a look round and see what’s on the market..

It it's post LandiRenzo 'IG' system (and if it has pulsed injectors it will be), if it's injector coils are close to 3ohms (not closer to 6ohm like early 'slow' spec injectors) then injectors could be replaced with a different type. If injectors are the only issue this would be the cheapest immediate fix but is it worth fitting an 'electronics' kit (ECU, loom, pressure sensor, switch) anyway. As Bri implied, ECU's can go wrong (still work but forget mapping / drive injectors peak/hold incorrectly), pressure sensors can go wrong and it could have an unusual / increasingly difficult to get hold of pressure sensor.

Most LandiRenzo software is very similar to generic AEB software, seems like just menu positions have been swapped around to give it a more distinct feel.. but not even to the extent of Tartarini (Tartarini is definitely generic AEB compatible with the exception of using a different spec interior switch and different spec temp sensors).

Ok, so there’s a BRC system on fleabay, is that any good ? Or prins?

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).

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