LPG sequential mounting locations

I decided to change my old single hole 70L stako tank to a 91L 4 hole tank because the old tank was looking tired and took forever to fill.

Once changed i soon realised that the new level sensor would not work with my existing setup unless i reprogram the ecu (OMVL millennium)
So after a few glasses for good measure i bought a new system - OMVL Dream XXI sequential kit.

Arrived yesterday with lots of wires, pipes and fittings.

I had a spare air intake which i have drilled for the injectors.

What i am wondering is where does everyones injector rails fit?
On initial glance there seems to be no room for the injector rails or the ECU.

So before i start ripping things out to make space does anyone have a sequential system in a Gems p38 which they can post a pic or 2 of showing mounting locations of injector rails and ecu?

Yes, I have one. I can take pics tomorrow (it's 10:40 pm here).
Thanks Ron, That would be great.

I have mounted the ECU behind the battery box, the vaporiser on the right (as you look at the car (UK Spec))

I did see a pic on the web where someone had mounted the injection rails on the front and back of the 'coffin' air inlet
I am struggling to find anywhere else.

My vaporiser is on the left, behind and below right of the EAS.

The ECU is near the battery.

The injectors are on brackets bolted to the plenum.

Hi,
I'm thinking about going sequential injection too.
Would you tell me where did you buy the front kit and which price?
What does involve the upgrade?

Cheers
I picked up the front end kit from www.fesautogas.co.uk, Speak with Nick.
The price was £600 for the front end OMVL Dream.
It contained everything i needed.
It is one of the systems which connect to the OBD connection allowing the system to learn the best settings on it's own.

To install i removed the inlet and drilled 1 injector hole for each inlet, threaded it for the injectors. Re-installed the inlet with new valley gasket.
Wiring was easy, all connections apart from +ve, -ve and OBD go into ecm
The vaporisor fitted next to valve block
I replaced a 6mm pipe front to back with 8mm to ensure i don't suffer from fuel starvation and fitted a 4 hole tank in the boot.

Your looking at 1 day of playing, mainly removing and replacing the inlet.

I got quotes for installing a new system which came out from £1800 to £2300, all in it cost me £1,000
(and £50 to get a certificate for my insurer if they ever ask me for one)

Yes i had seen their website with very good prices for a known brand of LPG system.

Any photos of the LPG install you did?

I worry about the thing that i may have to change my tank.

The thing is here you can't have a certificate for a DIY install so it has to be a straight install with no worries...

Mine is a KME system: http://www.kme.com.pl/diego/EN_index.html
Hi,
Did you really feel the power improvment swapping from single point LPG to sequential injection?

Regards

Flo
I've found that the power is so much better with a sequential system.

The single point system restricts the air flow into the engine by quite a lot making it lack in power for both petrol and LPG.

Once i fitted the omvl multi point system i found i could flaw it just the same on LPG as i can do on petrol
(With the bonus of never having to worry about getting a back fire which would happen if you were to flaw it with a single point)

Now swapped to multi point i find i'm getting more MPG on both petrol and LPG
Have a chat to your local dyno station, once you mention you have a single point LPG system they will tell you it's restricting the air flow and will cause a lack of power and performance.
Guys what's your MPG on LPG

I'm doing:
- 9.05 MPG city driving and heavy foot,
- 10.23 MPG combined,
- 11.2 MPG highway at 90 MPH Highway,
- 12.7 MPG at 70 MPH Highway

What? Not litres/100km as per the ISO standard? :D

With l/100km there is no confusion over the size of the gallon! :lol:

That's my standard too ;)

Last fill up : 23,21 l/100 city mainly which cost 44 euros. Range for 65 liters = 285 km (toroidal tank 72L)
