I have open loop LPG system on my '87 BMW 316 (carburetor). I was
advised to go closed loop. I found few lambda gas control kits online,
and I thought I could ask here if this is a good idea.

Am I going to benefit from going closed loop (and is it possible to do
so on the engine with carburetor)? Lower fuel consumption, less risk to
get engine too hot due to lean mixture? Smoother ride? Yes or no?

you should do! - it should only do good things!. though i if it is
only a small increase in mpg it may take a while to pay itself back.

>(and is it possible to do so on the engine with carburetor)? 

yes it is possible with a carb - why would it not be?
you replace the current manual tap in the gas line between the
vaporiser and mixer with an automatic tap with a stepper motor on it
that should vary depending on the lamda sensor input.

>Lower fuel consumption, 

my systems are still open loop (carbed cars). I have been told that i
will get a small increase in MPG by going closed. am tempted to try it
since the kit is fairly cheap.

>less risk to

this is true by the nature of the system!

>Smoother ride? Yes or no?

i cant see how it will make it much smoother unless your current open
loop system is totally out of tune!

I found somewhere on the Internet that lambda sensor system can correct
only small deviations of fuel mixture (a bit too rich, or a bit to
lean). That's why I asked.

Thank you for your response, this NG seems dead.

Normal Lambda sensors are fairly  narrow band, there are more expensive
broadband sensors available

I know, but all lambda gas control kits I found on the Internet can be
used with standard narrow band O2 sensor. Not sure about expensive
broadband ones.

And I asked this question with cheaper ones in mind.

Normal Lambda sensors are fairly  narrow band, there are more expensive
broadband sensors available

I know, but all lambda gas control kits I found on the Internet can be
used with standard narrow band O2 sensor. Not sure about expensive
broadband ones.

And I asked this question with cheaper ones in mind.

you should do! - it should only do good things!. though i if it is
only a small increase in mpg it may take a while to pay itself back.

>(and is it possible to do so on the engine with carburetor)? 

yes it is possible with a carb - why would it not be?
you replace the current manual tap in the gas line between the
vaporiser and mixer with an automatic tap with a stepper motor on it
that should vary depending on the lamda sensor input.

my systems are still open loop (carbed cars). I have been told that i
will get a small increase in MPG by going closed. am tempted to try it
since the kit is fairly cheap.

this is true by the nature of the system!

>Smoother ride? Yes or no?

i cant see how it will make it much smoother unless your current open
loop system is totally out of tune!
