Could always pop in and see JamesV6CDX and myself on the way back as we'll be tackling his install this weekend. It's on the way from Epsom to Plymouth (pretty much). A few more heads under the bonnet may spot something...

if i can i will, but my worry it that it could be coming home on the back of an AA wagon she is running very rough, has little accelaration and i am concerned it will be chucking crap into the cat and causing more cost)......


i will PM you nearer the end of the week if i can make it, thanks for the offer  

[JamesV6CDX]

It's running rough on petrol now?

Oh lordy... I hope we don't kill my Lambda!

yep, you have to introduce power otherwise it bogs down and runs very rich.

i have a feeling that because we didn't drill the nozzels we ran it too weak and killed the lambda, hence the issues

Which ones need drilling? The ones in the injectors, or the ones in the manifold? What do they need to be sized out to?

Cheers

Would running lean kill a lambda? As far as I know, it's only a sensor, to sense the gasses...?

the ones on the injectors, they need taking out to 2.5mm for the BHP output we have, if you put the 3.0 cams in remember to recalculate and possibly redrill

i am a bit annoyed with Jeremy about this, i asked what work was required and by his own admission he had over looked it, it's as much my fault as i should have questioned it when i read the manual

but if we have leaned it off too much and it has heated up badly then i was under the impression it could be damaged

I very much doubt running lean could have killed the Lambda sensor. I still suspect a wiring issue.

Unless it was driven hard with a lean mixture (not something to do until you're sure the engine is tuned perfectly), in which case the Lambda sensor could have been subjected to too high a temperature, I'm sure the problem lies elsewhere.

You say you have not drilled your injector nozzles yet?

I have just looked at mine, and I can see why they need drilling out. At the moment, they are little more than a pin hole, no way will enough gas get down there to run the V6....

no, mine need drilling.

currently they are 1mm and need boring out to 2.5 for 170 bhp TBH i didnt take much notice of them, i was looking at the nozzels in the manifold

Do you think this could be your problem?

one of them, yes,

i cant run auto calibration because the vapouriser will not get to 50 degrees according to the sensor, althouggh it is wayyyy to hot to hold for any length of time.

once these are sorted then it will be up and running on gas

[Kevin Wood]

Is the vapouriser temperature sensor integrated into the unit or a screw-in device like a gauge sensor?

Just thinking we can maybe compare resistance readings with JV6CDX's one?

We can also substitute resistances to force it to read a sensible value, which might get you up and running. You'd have to change over to gas manually or else it would try to do it on a stone cold engine but otherwise it might help.

the temp sensor sits on the body of the vapouriser, it is nothing more than a thermister.

Tylor (Jeremy's tech guy) is sending me a spare one in the post so we have that as a fall back, one thing he has commented on is that the OBD system automatically chooses the sensors, it can sometimes get those wrong and they can give false readings.

once the vapouriser is at 50 degrees you can run autocalibration and it will mirror the petrol injection settings so in theory there should be no noticable difference between petrol and LPG, he said it can be done manually but it is not as accurate as you have to set up lots of points on the map
