EGO Time Delay for Idle

Post by Maddog6961 »

I'd like to see this feature implemented in the extra code. It is a feature that allows you to set a delay time for EGO at idle engine speeds. I know my O2 sensor readings are usually lagged at idle due to the exhaust gas velocity and my O2 sensor placement. I think EGO correction at idle would work a lot better if this feature was possible. It would need a field for defining what the idle speed threshold is and then an engine cycle count/delay period for the O2 signals.

I have a feeling this is built into the transport delay function already, but I have no idea how to use it. Could someone explain to me how I might set this up for idle if this feature is already active?

The transport delay function handles this pretty well for me. I'm running EGO correction everywhere as soon as CLT is high enough. Works a charm for me.

Search for transport delay and how to compute it for your engine. My settings for my M30 engine (m30b35 with schrick 284 cam) is:

Transport delay 1: 10
Transport delay 2: 1000
P: 30
I: 20
D: 10

Set Active above RPM to 600 and you're good to go. The actual settings for your engine may be similar, but probably not identical.
