Your thread got me to thinking .On my way to work this morning I decided to watch my wideband gauge. On my Honda even immediately after start up It seems to feel cut under deceleration.

The car was still in open loop though .I know this because my 02 sensor is programmed to run at 16 to 1 as opposed to 14.7

I was idling at 14.4 to 1 and under load at around 13.8

But as Soon as I let off the gas, The gauge pegged at 22.4 to 1. It may not have been completely cutting Fuel but it was definitely at-least leaning it out .

It appeares that it only took my car about 40-50 seconds to go in to closeed loop mode. This morning 71°.

There is a chance that the 02 sensor I installed warms up faster than the factory one and that could play a role in that though...
