Title: Well, it runs.. on LPG.
Post by: Kevin Wood on 19 July 2008, 21:35:55

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. :-/

I'll take some more and post them. I took pictures at every step to start with. Then, I'm ashamed to say, I slipped gradually into "get the 'kin thing finished" mode. ;D

Strange how it ran with so little deviation after calibration, when my V6 would hardly pull at all, until it was mapped  :-/
