A lean mixture can also cause a pop and can be caused by the stepper motor controlled actuator (the bit between the vaporiser and the mixer ring) being stuck at one opening. Plugs, HT leads and general muck and crud around the HT side of the ignition coils can all cause it. Usual cause of a misfire on LPG leading to a backfire, is a dodgy spark. Check also the breather hoses into the plenum chamber, one or both of them could have been blown off too. If the air leak is between the MAF and the throttle then the misfire is being caused by the amount od air going into the engine not matching the amount of air the MAF says is going into the engine. Possibly the MAF sensor (I've seen one where the mesh has been blown out) or you have an air leak on the inlet. The reason it is running like a dog is because the backfire has damaged something. Go to click on Programming interface kits on the left side and scroll down to AEB and there's a choice of RS232 or USB cables (because the OMVL Millennium is a rebadged AEB 175 Leonardo with different firmware) and it comes with the software.
SAGEM LPG INJECTION SOFTWARE
Software can be downloaded from here \Software OMVL\OMVL Millennium 3.zip but you'll need the cable to connect to the system. Nowt wrong with an OMVL R90E and a Millennium, that's what I ran on my Classic LSE and what has run for the last 150,000 miles on the P38.
SAGEM LPG INJECTION HOW TO
Third ask, any ideas of how to get it running well enough to make it 5 miles to the nearest substantial cliff? Second ask, where to start looking for the brand new petrol fault. The installation's a mess and will probably require an end to end fault finding voyage.Īnyway, a the end of this ramble my question:Ĭan anyone give me some pointers re diagnostic software for the LPG? I know it's out there, just not where. I've got a Hawkeye to do diagnostics on the petrol side of things (once it gets light), though I'm still learning it's little ways, but have nothing similar to do anything with the gas side. Limped home (only 1/2 mile or so), dumped it in the drive and have researched how much it's insured for for accidentally falling off a cliff. Only problem is, it now won't run on gas at all and has a spectacular misfire on petrol- sounds like at least a couple of cylinders out and v weak mixture. Very satisfying as they were both clogged with aeons of neglect. Long story short, cleaned the MAF and air filter. Hit the petrol switch and finished the trip. On the way to the workshop, on gas, achieved a large backfire which woke a few cows, and ground to an almost halt. Put treating this on the to-do list, but decided to sort out the rich running on petrol first (it always has) by cleaning the MAF so that my fall-back system was healthy. No more water loss or pressurisation of system then or since, but the switch to LPG on startup was no longer instant and there was a hint of a misfire or what I would say if petrol was a splashy weak mixture kind of response. Wisps of steam around the water plumbing. Working my way slowly through it's endless list of "issues", I was distracted a few days ago by signs of overheating around the vapouriser.

The LPG system is a single point (yeah, I know, but it's what came with it and seemed to behave quite well) on GEMS, wait for it: My 2 week old soon-to-be-recycled-into-a-boat-anchor is driving me to distraction.
