Just finished changing a brake cylinder and shocker on my son's old Hyundai Accent that'll be going to girlfriend's son in law for him to learn to drive in, sat in my car recharging laptop and waiting for a Freelander to be dropped off from an accident recovery firm.. I'm tasked with fixing the Freelander's LPG system, fitted less than a year ago by 'LPG Experts', because apparently ever since the accident (body damage repaired a while ago now) the LPG system has cut back to petrol when owner puts her foot down... Yeah rite! Me thinks it cut back to petrol when she put her foot down even before the accident but we'll see.. I bet she got a bad neck from the accident as well!
Morat, looks like most bits are BRC - Reducer is, ribbed back ECU could be Europgas or Piro but is most likely BRC Seq56 (since BRC/Bosch sensor is pictured T'd into reducer vac connection). Difficult to make injectors out as many types look similar to those but they'e not BRC - Maybe GFI, Tartarini, Rail. etc.. Which could be problematic on a more demanding engine if ECU is Seq56 as best results would only be with quicker injectors, but I reckon probably workable on the 4L Jeep. How does it drive on LPG?
Since nobody's been banned yet for talking Jeeps and this will still be under 300 words (ahem Gilbert! ;-) ]... My Jeep saw the road for the first time in years the other day, just a trip to the jet wash. Before standing it up I'd at least disconnected the battery, so that was OK just wanted a charge. Charged, checked engine and ancillaries weren't seized, it started first turn of the key and drove OKish except for some steering warble that'll be down to corroded discs, I hope. This has a K&N too...I nicked it's shallow design pre 2000 air box to fit on a post 2000 model I converted a few years ago. No clearance between air box and bonnet with new style air box and a mixer fitted. Would have been plenty of places to fit your ECU without the K&N...
