Im just interested to know, if I use an air fuel ratio guage that was designed for petrol on an LPG application will it be accurete? my understanding is that the stoich ratio for LPG is 15.8:1 where as petrol is 14.5:1... so would that mean my guage should read laener since it is using more air under combustion? or am I missing something Some original photos have not been recovered yet.

yes, if its a decent guage it should be able to read in lambda also. lambda is the same no matter what fuel, so set it to that. tune WOT to around 0.83 get idle close to 0.96 (not farken 1.00 because you will have/hear a slight miss, trust me). then start piss farting around with the cruise circuits (i still havent been bothered to do this lol, still too fat on cruise, my economy shows ) Some original photos have not been recovered yet.

I have just added a front mount and didn't wanna run my BOV onymore because of police interest. My concern is that the compressive surge will unbalance the converter and lean off the mixtures too much between gear changes. Short of buying a plumb back i dunno how else to get rid of the noise has anyone had experiance on this? Some original photos have not been recovered yet.
