lpg set up / tuning BRC

Does anyone have any infomation on the BRC single point lpg systems. I have one fitted to my disco v8i and want to make sure its set up right. Only getting 8 MPG but runs and drives fine?. Any Info would be a help the brc website is usless.

8mpg you sure you haven't got a huuugge leak somewhere? i can't imagine it using that much gas even if you were flat out everywhere

i have thought down the lines of a leak myself but it does about the same on petrol as lpg!!!
had it tuned and checked on a co meter and its not running super rich but would only just pass mot

Hi.

I am asuming that as far as you are aware ther are no problems with the engine regarding compression, air flow meter, throttle potentiometer and all the plugs are fine. Mine had an over fueling fault but only on petrol. Not familiar with your lpg kit. Does it have a big adjuster on the inlet (dos it supply gas through the air intake)?
Cheers, Nick.

Hi no not as far as i know.
Plugs are new
i have had it 'pluged in' and diagnostic checked. The only problem found was a lambda sensor down on one bank ( this was the same sensor that had been tapped into for the lpg) so i was hopefull that that was the problem. No such luck new sensor has made no improvment!

engine runs really nice just very poor mpg

seems very odd can't understand how it feel like it's running well yet doing so badly on the mpg as nick said if the motor is healthy there must be something on the ignition/ fuel system a long way out
