Fek knows what mine is on 

You don't have a Stag 300 Plus

Oh. Good point 

[Lazydocker]

Hmmm. My software version is 6 something. I couldn't get the interface to work with 9. Couldn't find the drivers.

Right... You might have to update the firmware, then go to AC 7, then update again and go to AC 9

If you can't get them I'm sure Kev will, like me, have all the versions installed still as a just in case

Oh Lordy, how many versions behind is my MV6 now then

Doz, dont drill to 2.5, its too big.

Yeah, about time yours were looked at really

[doz]

Right. I'll leave it alone now until some when else can take a look. I'm pretty much at my I.T limits now.

[doz]

Right. I've been playing again. Managed to update to version 7 which then helpfully asked me if I wanted 9.1. So I got the latest firmware installed annnnnnnnnnnnnnnd it ran like a bag of bolts. However now it was easy to see I was suffering from a misfire which seemed to improve with revs. So after a chat with  Paul I found out how I could drop out each cylinder on lpg one at a time and let that one cylinder run on petrol. It soon become apparent cylinder 5 linked to LPG injector 3 was the root cause of all my issues. So I did the compressed air down to the gas nozzles again and this one did sound different. So off with the plenum again and this time the tress to find nothing amiss. So back together start it up annnnnnnnnnnnnnnnnd it's a bag of bolts again. So I thought it must be ignition related. As I had to move the injector block I had an idea to drop out the cylinder 5 solenoid. Oh I don't believe it!!!! after all the pants I've been through sat there staring me right in the mincers is a tiny weeny bit of brown packing tape stuck on the seat of the nozzle. I kid you not. How I laughed....... actually that's a right lie. I swore lots. Packing tape removed I checked the solenoid operation across the battery and it worked wonders. So I put it back together fired up and waited for the car to switch to gas. Success!! All six cylinders present and correct!!!!. I wanted to do the base calibration again but I had to wait for the reducer to make 50 degrees C. So while I waited with the engine running I started refitting the scuttle I had removed to double check the condition of the Dis-pack. I didn't even notice the change to gas once the calibration was done it was that smooth. So I took it for another bimble and it now seems to run well at all revs. It still needs mapping. I couldn't get the software to draw the blue and green line. Version 9 is a lot different to 6. So any help with that would be gratefully appreciated. Oh and as it stands at the moment it's going lean at WOT. Not sure if that's the mapping or the jets are to small. Like I said I'll need a hand with this part.

That's brilliant mate, well done in finding that stumbling block

I can't believe there's been 1898 views and 259 replies to this post. Just proves what a top bunch of lads we have on this forum. You gas guzzerlin gurus I take my hat of to you 

[Entwood]

If memory serves .. you got it to map OK before ..when it was actually only running on 5 cylinders Now its running on 6 ...

Is there a way to completely delete the map you did the first time and start again from scratch, rather than trying to "modify" the known wrong map

If that's what you've done just ignore me .. my system is not mappable ....  so I don't have to bother

[doz]

It was mapped on version 6 of the software. Now I'm using 9.1 it's loads more options and it even has a long term calibration thingy wotsit. I just can't get my head round it to do the calibration. The previous attempts won't really mean much now. I've done the base idle calibration several times since.

I've been watching this thread with interest where I'm thinking about adding LPG to mine and I'm really glad that you have managed to find the fault and getting running properly. 

[VXL V6]

Well done sir, your on the home straight now 

Want to do mine   

[doz]

Go for it all I'd say is you need plenty of patients and be prepared to do it over a few weeks of evenings or a couple of weekends if your doing it on your own.

Ditto - well done doz

[tunnie]

Great stuff. Beer well earned 

[Lazydocker]

Excellent... Told you today it would be something simple

Go back to basics with mapping and start completely afresh

[doz]

Tried that Paul. I did the basic mapping at idle. Then it tells me to do it on the road but I get another box open up with two tick box options. What ever I do with these I just can't seem to get the same level of control of the curves. Very strange.
