Just a bit of history - I bought a facelift Elite, that was misfiring. It poisoned the cats and lambdas, blocked the exhausts, and burnt a great big hole in the petrol tank.
Things were not looking so good.
For the last several weeks, I have been sorting it out on the driveway, doing a couple of hours in the evenings after work, and at weekends.
Obviously, before I could LPG it, the petrol side of things had to be sorted, so it was running right.
This was achieved by new DIS, Plugs, Leads, followed by 2 new Cats, new lambdas, and new eternalcar catback exhaust. (Oh, and a new petrol tank, of course!)
Well the good news was - this cured the miss, and she was once again running a treat
So - onto the LPG.
The kit - is the Stag 300 plus, with 3D fuel mapping. It's not a Teilo kit - got it from eBay.
First things first - while the petrol tank was off, it was ain ideal time to mount the LPG tank in the boot. I went for a 70 litre toriodal tank, in the spare wheel well - which is really the biggest you can get in an Estate, without cutting the car about. It involves raising the boot floor by about 6cm, but in reality this causes no problems.
I fitted the multivalve, which was a fiddle in the toriodal, but do-able.
Pipes are running under the car as per usual.
The vaporisor is on the inner wing, taking a coolant feed incercepted from the HBV feed, which is what we usually do.
Vapour pipes and filter go up behind servo, so all out of sight.
A pictures tell a thousand words - so as soon as I have some, I shall upload them all - but for now, I will suffice to say that, for an ametuer (yes that's what I am, no more than an interested enthusiast), it is a very tidy, uptogether install, which I have no doubt is LPGA compliant.
I've installed it in such a way that, minimal extra effort is required for routine work and servicing, plenum removal, and such.
The LPG ECU, is in the main engine ECU box. It's now a little crowded in there - but, it works well.
The wiring is nice and tidy - you can obviously see traces of the install around the engine bay, but all in all, nothing jumps out at you.
The switch, is in the centre console.
Anyway - once it was all together, I connected to the LPG ECU and set the paramaters.
My injectors I drilled to 3mm, and have after some experimentation, found an optimal gas pressure of 1.33bar.
It really was just then a case of pressing the button, and she started chirping away on gas, like it had always run on the stuff
I performed the auto calibration, and adjusted the fuel map on the road.
From the word go, it has run on gas exactly the same as petrol.
You can't tell what fuel you're on - it pulls like a rocket, on either fuel, right up to the redline - there is absolutely zero power loss on LPG.
Interestingly, I didn't use the usual Valtek Injectors - I used the "magic jet" rails, which, are apparently very highly rated. It cost a bit more - but, I would say it's worth it. First impressions show them to be an excellent LPG injector.
In a nutshell, I am a happy bunny
It is a tidy, and very functional insall
Cost me around about £850 all in, instead of the usual £700/£750, as I had to get a few extra bits, and had a multivalve issue, but all in all - supurb! Sill heck of a lot less than a dealer install!
Have now got to the bottom of the fault code issue too (not LPG related in the slightest) - so happy days.
Just need to sort out the suspension for the MOT, and I should be sorted
