I believe 4-hole is recommended for 3.0 ltrs and above due to fuel flow requirement .. especially at WOT/High RPM .... (and single hole might explain the lag some folks get Although vapouriser will also have a large effect    )

TB's flows enough LPG (but is approaching borderline). The Lag is present on 4 hole setups too

But, after my visit there on Friday, we think we're getting somewhere. Seems to be caused by the Vaporiser. At gear change the injector times spike down (followed by the LPG times as it's a piggyback system), causing the LPG pressure to "overshoot" and cause brief flooding when the injectors open again. This is hopefully going to be fixed with the new vaporisers

Just out of interest, do you know if your system has a timing processor?

If I knew what one of them was I would be able to answer you !!

Write ups for my system ...

perhaps the info you seek is somewhere in there !!!

Yours is the Sequent 56 system IIRC? In which case it does have an inbuilt timing processor

Perhaps we're getting somewhere. ISTR that Teilo's timing processor is about £25 :-/

I don't see any connections to the crank sensor in the sequent wiring diagrams, though.

Those manuals are very handy reference material for anyone contemplating a conversion for the first time, though. All except the picture on page 39 of some gibbon drilling an inlet manifold in-situ.

Good point... Says timing advance processor built in though :-/

Mind you, somewhere else it says "except sequent 56"

Think the reducer is the problem though. Must do some live data runs with the tech 2 and see what the injector times do at changeover

[edit]Just had another look... Timing processor is an additional feature that may or may not have been used There was talk about trying one on mine but we forgot Might get one sent up at some point if the lag still exists with the new reducers[/edit]

Changing my injectors for 'Magic Jet' ones on my 2.5 Elite, instantly removed all traces of lag...

Can you remember what vaporiser you had though?

I wouldn't have thought the lag was present in the first place on a 2.5... Albs' one is fine and, looking at the setup as I did in the past, it shouldn't be

Magic jet injectors are fine unless you get the slightest trace of dirty fuel and then the can gum up... Done a lot of research

The Red Voltec ones should be up to it... I've seen them running more powerful cars with no issues Just a case of eliminating the lag... Seems to be down to injector timings at changeover because the petrol timings spike downwards (which the LPG ones copy ) causing the LPG pressure to rise (overshoot) and then on the next injection cycle inject too much gas.

We think a different vaporiser may resolve it as the ones in our original kits were a bit slow to react... Timing processor is another possibility and would probably improve economy a little :-/

[JamesV6CDX]

Will be interested in the outcome

[sassanach]

i have just swapped out the voltec injectors for magic jet on my caddy and the car is transformed.i was running 3.2 dia jets with the voltec, im down to 2.5 on the "magic's"and its still complaining that the jets are too large.ps i am already running a rl90 vapouriser as the original was crap!!

[JamesV6CDX]

I must say, Will, I certainly found the magic jet's better...

[Lazydocker]

My only concern with them is the risk of gumming :-/ :-/

Going to try the reducer first, and possibly the timing processor, and see where we go from there. At the end of the day, I've not had to pay any extra for anything I've tried so far

[TheBoy]

I guess we will have to wait and see if the new injectors supplied make a difference.

I think it'll be the vaporiser that makes a bigger difference

So what jet size are we drilling with these current injecters? Might open the box tomorrow.

When you open the box, can you check if he's put in a diagnostic lead for connecting to lappy, as I don't have one with mine...   ...and I can't get hold of him again to discuss or order my 80l tank

Finally have got miggy back on the road with manifold nozzles done, Teilo posted a pair of nozzles and they came as promised late Wed so managed to get the manifold and associated parts back by Thurs evening, so did my east coast trip yesterday. What a hard  job I had getting the manifold off and worse still back in position,the gap between the 2 cam covers was very very tight. Until the equaliser or is it vapouriser issue is sorted I'm gong to start to install the tank.
