For petrol, I'd expect long terms to be pretty much 0%

For LPG, ideally keep them between -10 to +10%

OK .. I'll check them after the Paris trip this weekend on LPG.

Appreciate your teaching

If you get a stored trim code, its exceeded 20%. If you get an EML, its gone beyond 23-25% (I can't say accurately, as not that many are that bad)

Never seen one of them, only codes I've ever seen on this one have been the 0420/0430 which I expect to get (again) within the next week (French LPG) and the 030* mess I got t'other week.

Time you relocated the O2's then Nige!

The major issue we have on the diag here is the addition of the LPG system. As most will know, LPG piggy backs onto the Petrol ecu and modifies the injector pulses for use with LPG based on a few simple sensor inputs.

A downside of this is that there is the need to manualy map the system plus its a compromised approach hence its easy to see an LPG setup showing fuel trims which are not ideal.

It would be very good of the LPG setups would also monitor the O2' sensors and provide trims for the system.

When are you free ?   

On a more serious note ..  Thanks for the info ... as mine is a BRC Sequent 56 system there is no manual mapping facility available to me, I believe - from reading the stuff I downloaded some while back - that the BRC "self maps", but I'm not 100% certain. According to that paperwork the ECU does have lambda inputs. I do know it has not been remapped since installed - I watched the last couple of "services" (3 & 4 years ago) which comprised of a filter change, a "sniffer" around the pipework, and plugging in an analyzer to the OBDII slot and stating "no problems" .. for which I was charged silly money. I've done my own filter changes/sniffs/and OBDII checks ever since ..

The LPG installers in Swindon (not the ones I used for conversion) have recently taken on the BRC franchise, do you think its worth having them "remap" or "recalibrate" the system ?? It has been in  5 years and 53,000 miles without one ??

Relocation of O2 sensors is much easier for me to do now thanks to the aquisition of a plasma cutter.

Thats convenient...  ...you're only about 80 miles from me

Perhaps we ought to form a queue ..

I'm closer...... 

 

Mind you, I not got 0420 or 0430's yet!..... My last 3.2 was the first one reported on here to get them though!

The worst part about re-locating them is removing the front pipes.

That's the worry ... could be a 20 minute job or a 2 hour job ... makes asking someone to do it for you either a favour or an imposition, and you don't know which until the point of no return !!

Worst case scenario is drilling out the centre pipe bolts but, as the cat is being removed and given a good pillar drill thats not a big issue.

So parts required are:

2 off Lambda bosses
2 off Lambda boss blanking plugs
2 off front pipe to manifold gaskets
4 off centre section to front pipe bolts.
2 off new front pipe to manifold nuts (often not needed hence only two just in case!)

Then I would say 1-2 hours typical (less or best case)

Jekyll and Hyde syndrome i'm afraid, I'm either driving in kickdown or gently trundling along with the traffic flow!
