Hi all, it's been a while since I've been here as my Astra is still running fine :)
I have just bought a vauxhall omega 3.2 v6 with a Landirezo gas kit fitted
I need the software and lead (maybe other things I don't know) as I need to
Get into the System to alter the time the gas will come on etc.
Can anyone help me please? Thanks Rae.

You can pickup the lead either from WTV (http://lpg-kits.com/) or lpg shop (you need 2 leads in their case, http://www.lpgshop.co.uk/base-ccy-usb-l ... to-milano/ and http://www.lpgshop.co.uk/diagnostic-int ... ndi-renzo/). Other places may have it as well, the WTV one comes with the software, not sure on any others.

You'd best check which ecu it is first though, to be sure you can get the software.

The older ones (Omegas for example) won't let you set a switchover below 40 degrees, and some versions of the software will only let you set switchover at 1600rpm (the older version of the same software will let you set it lower though). Also if its cold starting i found you couldn't get it to switch over until it had been running approx a minute on petrol. Warm restarts tended to be a lot quicker.

Tinley have them, but they aren't cheap > https://tinleytech.co.uk/shop/lpg-parts ... ueblack-2/

They are usually referred to as MED injectors.

It may be worth a try with some IC12 or similar injector cleaner. Not sure if you can use any other injectors on the Landi-Renzo (is it Omegas you've got?) I remember from mine that there wasn't a lot of options there. If you could find alternative injectors they may well be better (and cheaper). Be aware though that the Med rail has both the pressure sensor intergrated into it, and 14mm pipe which is unusual. You could get round the pipe fairly easily (use a replaceable filter with 14mm inlet and 12mm outlet to bridge the size gap).

Whats it doing to make you think the injectors are at fault?

Thank you Brian, they are very noisy I took the gas pipe to the injectors off and sprayed some brake cleaner it and run the engine then I done the same with Wd40 it’s a bit better now but I think they’re worn out as they’ve done over 120,000 miles Yes they are the round Omega’s black👍

Those injectors are noisy as they get old - mine were very noisy. They aren't known for being particually good either. Not sure if a better option is available thats compatible with your ECU, though do you have the pressure sensor mounted in the end of the injector rail on your setup?
