Hey guys,

I've installed LPG on my Chevy G20, it's a 350 TBI, I'm using an Ostrich 2.0 (with socketbooster) to control the 7747 ECM (mainly the spark tables). I've also installed an Innovate LC1 Wideband and AFR gauge.

I am having an issue where when I start it from cold, the mixture REALLY leans out at idle, which should be the opposite behaviour, as LPG before it's warmed up will stay liquid and run rich. I believe it could be the IAC causing this as I came across another chap with similar issues, but on a carb, turning in his idle control screws resolved the issue.

What would the easiest way of making sure it stayed closed? Or am I barking up the wrong tree?

Also, and this is slightly unrelated, can I use the 2nd analogue output on the Innovate LC1 to connect to the standard O2 sensor connector to get rid of the damn CEL??
