It's here!

Stag 300-6-plus, with 3d mapping and majic rail injectors

Looks like it's all there bar a few pipes. Only one thing I find odd. On the injector blocks, there are two connections for a gas feed. The main (10mm?) gas feed to the injectors, and at the other end of the block, there is a vaccum/4mm type connection... what's that all about?  :-/

Also, observation - the injectors can't be "drilled" on these - there is two preset sizes - the normal size is quite bit... and you can screw an insert in, to reduce nozzle size... not sure how ideal that is for fine tuning... but the Mjet injectors are meant to be raved about....

[Lazydocker]

I've heard lots of good things about them

I reckon you need to stick the inserts in a box and try without to start with

Oh... And apparently the 3D mapping can be a right PITA to get right... Should have had a go when I did Tunnie's but the map looked so good I didn't bother

Is there not a blanking plug that can be put into the end of the fuel rail instead of the smaller hose barb? If not I would connect the two together with a length of hose.

Is the measurement tee the same as Teilo's kits? Just wondering if they are for the vapour pressure sensor?

I would regard the 3D map as a facility to tweak out any minor running problems in certain areas of the map.

You can still tune it as a 2D setup as a starting point, which is no less easy than on the older ECUs. 3D is then only required (if required) for fine tuning.

I would tune the 3D part of the map by watching the fuel trims on a Tech 2, TBH. I don't think you could achieve much tuning it by the seat of the pants.

anyone want to guess what i'm going to ask?

only need 1 guess i would think...

[JamesV6CDX]

no idea!

He'll be back as soon as his Nokia has re-booted.

Will the upgraded kit sort the lag issue? Will it be genuine plug and play perfectly, or have you got to spend hours fiddling with settings?

...obviously time will tell. So come on James get cracking, want to know how it runs. 

[Kevin Wood]

1) I doubt it.
2) Yes. (you will have to spend hours...)

It's actually the ECU we fitted to Jaime's car but didn't bother or need to fiddle with the 3D part.

By the time the lag occurs, the LPG injectors are fully open so I doubt more flexibility in the mapping will help, I'm afraid.

The fully "plug and play" ECU is Teilo's own development AIUI. He was looking for beta testers, though, according to Lazydocker.

Right,

LPG tank ordered from tinleytech.

Toriodal, 70 litre tank. 650mm by 270mm.

Gone for a towbar filler.

All the pipes and fittings and connections you can shake a stick at, have also been ordered

This weekend, while awaiting a new petrol tank, I am going to do the backend and pipe run, and mount the Vap, and it's associated water connections 

[JamesV6CDX]

Tank will involve creating a highish false floor to the boot - 7cm to be exact. Can live with that though, will still be plenty of dog/camping room

At 80% capacity, this tank will hold 56 litres in total.

This is 12.3 gallons

So, if I can get 23mpg, I will have a range of 282.9 miles, which is a decent compromise.

[Jimbob]

like the sound of that...

So whats the 'bits bill' standing at then?

[JamesV6CDX]

So whats the 'bits bill' standing at then?

The entire conversion cost (excluding materials to make the raised floor) is standing at £700

Based on petrol being 117.0 p per litre and an average of 30mpg = the cost of running on petrol is 17.9p a mile

Based on LPG being 60p per litre and an average of 23mpg = the cost of running on LPG is 11.9p per litre

This is a total saving of 6p per mile, therefore it will take 11,666 miles to break even 

[Kevin Wood]

it will take 11,666 miles to break even

Time to start a book on how many miles until it's up for sale?
