Full time LPG

As you want to run 100% LPG then you do have a couple of options.
1) you could fit a traditional mixer system possibly with lambda control but as a gas only car I'd stay basic with a open loop mixer. The down side is the managment light will come on and there is a risk of backfiring. Quite a strong risk with the 16 valve engine.

2) youy could go multi point but only a few systems will automaticaly start on gas. I set my own cars up that way and also set up the taxis I do to start on gas when the engine is warm. A lot of teh boats I have done on multi point have been gas only as the gas tank goes where the petrol tank went. The problem with that is not having petrol as a referance when setting up but with experiance this is not a problem. Not all cars will start on LPG from cold but the older volvo's never seem to have a problem other than needing a lttle cranking.

If you want to be running on gas 100% of the time check with the installer that the system they will use can do it and they have experiance of both your model and setting up gas only cars.

Ive used profess on a couple of cars including BMW X5 and a S60 2.4T. and I have to disagree with the the initial comment above. What you find is that the conversion is done in a day. With most people travelling a fair distance, hanging around for the car, then coming back to pick it up later. Then travelling all the way home with the car. Every car is different and may require a little more set up on the management side to get the LPG running how the owner wants. My X5 ran geat on LPG but went back up for a little tweak a few days later and ran fine forever after, same was the case with the S60. Both cars gave massive improvements on LPG and at around £1200 for the cost of the conversion, no wonder people are prepared to travel a long way for a profess conversion when others are clearly overcharging and offering conversions between £2000 and £3000! Fortunately he's just up the road from me, all I will say is that any LPG conversion will most likely need to go back for a further set up. Ive used other LPG installers and paid for new conversions with other companies and guess what ,.. they all went back for a further management adjustment after the initial installation.

Hi Ambit,

Thanks for your comments, I will take your experience of 'Profess' into consideration..like Dai/Classicswede said, 'do your homework first!' and all (in theory) should be fine.. So your info is gratefully received. Thanks!

It is nice to see good coments aboiut them for a change.

Would you be able to take some photo's of your conversions so we can see how neat etc they are. At least with you being local you were able to take the car back for retune.

My trouble is I only ever hear/see the problem cars that have come from there. No one comes to me and says so and so did a great conversion for me.
