To get it tuned properly you will want to use a 2,3,4 or 5 gas analyzer.
I just tuned the GRA Setup on my corty, and with the 2 gas analyzer, I could find the best (most efficient) idle mixture. Lowest HC count, .5-3.0 CO.
For WOT you can use a wide band, but the analyzers tell you more about what is going on, they just have a slow response rate .
You won't need a dyno to get it tuned. Most important for everyday driving will be idle and cruise mixtures which can easily be checked on the street.
WOT can also be checked on the street, just need more room

orite i think i understand, all i use it for is driving around in traffic and on a cruise, while givin it to it abit, so yeah a normal tune would be fine, i think il just take it there, they'll have all the right stuff to tune it as u said, cheers thanks mate

yep...... slightly rich @WOT is still ok with LPG on a dyno with a 4 gas & a wide band & its always right !! I set up all performance LPG cars that way......a tune will not fix a leak if you smell gas no matter how you adjust it.

so i took it to get tuned today. The place didnt have a dyno, and after leaving it their for two hours they say that they couldnt really do much because for this system (gas research, which they say is popular in Vic) you need the right tools and preferably a dyno. I took it their because it was running rich, and when you turn the car off their is a realli strong smell of gas. They recon that it might just be from the regulators as their is gas left over when the car is switched off. Can anyone reccomend a place in sydney which can work with this type of system and has a dyno? cheers

Look above your last post !
