Looking at the wiring diagram, there is only one wire for lambda sensing.... surely it needs to read data from both o2 sensors?

both......

the loom has provision for dual sensor cars, it was one of the queries i raised

Fantastic..

What's the injector wiring mod all about then? Do you have to cut any wires or is it plug and play?

one of the leads on the petrol injector loom needs to be interrupted , if you look at the wiring diagram it shows that there is a wire that should be cut, it is the common wire.
part of the LPG loom contains a set of plugs that then plug into the petrol injectors and the old injector plugs then connect to the lpg loom, i'm no expert but it looks like the ECU uses sinalling from the motronic system in order to fire the LPG injectors in the correct sequence, that's a guess mind you.

 

The diagram shows 6 that need to be cut..

that's the ones, you do it on the injection loom, the kit comes with heat shrink so you can seal off the tips as well

Will need to investigate that, I see no need to be cutting the loom if the piggy back leads are supplied  :-/

What sort of drop in MPG do you anticipate?

Additionally, the LPG filter on the diagram shows one input, one output (to the measurement tee) - but the filter has two outputs, so I'm not sure what the score is there.

i would imagine i will be looking at 25mpg, if i can get that then i will be happy, i'm currently getting 30 on a run up to nottingham....

my fuel bill is now about 120 a week, i need to reduce that asap

That is what SGI is all about

again the info i got from that was that the measurement tee sits on one of the lines, it doesn't need to have two of them, so the filter will be the T for the gas lines.

  glad i could help

You mentioned you were doing some more today in another thread - How did you get on today mate?

[Jay w]

not as well as i wanted to  

The plan for today was to mount the injectors and ECU as well as starring to route the loom.

Managed to find a space in the scuttle for the ecu and still be able to change the pollen filter without removing it, drilled the holes for the bracket but then found the bolt i had were too short.

then spent about 2 hours messing around with pieces of metal trying to make brackets, the drivers side of the engine i have decided not to drill/tap but use pick ups from exsisting points, the passenger side i am still not sure, the 2.5 manifold being shorter means that things are closer together and so there is less space for new additions

no matter what i did today nothing seemed to work so cold and frustrated i called it a day, i am off thurs/fri of this week so we will attack with renewed vigour

You'll get there, it's crap working on cars when it's so cold!

right......back on the case....

I have 2 days off and need to get it done in that time, reason for not doing anthing over the weekend was i couldn't stop being sick, was very ill.

Having just been to london and back and paide nearly £100 on fuel i am on a mission, me and the car are going over to a friends garage and when it leaves it will be running LPG.

hopefully

Fan, Friggin, Tastic.

Very best wishes.

If I'm lucky, and manage to fix mine fast, maybe I could come and see the kit installed on it?

Best of luck !

does anyone know where the lambda wiring enters the engine bay....can find it for love nor money?
