Been a funny day. Put the finishing touches to the LPG install, decided to take it out and fill it with gas.
First gas station - nozzle wouldn't connect properly (may have been user error
), second station was out of gas, third and fourth were on the map but couldn't find them in reality. Ended up filling at a motorway services at vast expense (but less than petrol) and burning about 1/4 of a tank of petrol for 1 tank of LPG. Still, it filled nice and quickly to 65 litres and shut of (right on the money for an 80L tank).
Anyway, switched over to LPG. Ran like a bag of spanners.
Looked at the live data and the two lambda loops are going mad fighting each other. Then I noticed the injector durations on the two banks were up and down like a yo-yo, and of each bank there was one injector duration that was dissimilar to the other 2.
Eventually it dawned on me. I'd got the injector signals for cylinders 2 and 3 swapped over.
Plenum off, re-wire, back together and it runs on LPG like a dream. With no manual tweaking after an initial auto-calibrate it's within 5% deviation across the board and runs just like it does on petrol.
A successful day - in a round-about way. :-/
