- new bits -

It's been a while, hasn't it...

In order to address the emissions issue, I have been busy increasing my debt. I have purchased an exhaust with a catalytic converter in it (so that I don't have to keep borrowing Ian's). I have also purchased a Power Commander, so that I can control the engine's fuelling. And I have borrowed, with a view to buying later on, an Innovate LC-1 wideband lamdba sensor controller, so that I can see the effect of altering the fuelling.

The initial goals are to use the latter 2 widgets to map the SVA emissions test sites (Idle and 2500rpm fast idle) to have a Lambda ratio of 1 or slightly less - SVA requires that it averages out at between 0.97 and 1.03. Hopefuly the catalytic converter will mop up enough HCs and CO to pass those requirements as well.

Later on I shall use logging software and ChrispyG's log analysissoftware to build up the complete map

So - to start, I used this evening to fit the PC and the LC-1. Both can be connected to a computer, so I did so. The PC software sees the PC fine, but the LC-1 logger software doesn't seem to see the LC-1. Strangely, one of the other Innovate tools, the LM Manager does appear to detect the LC-1. I shall consult the Cam7 oracle for ideas...
