Info Post-Fuel Table/trim explanation.
Users: post fuel value is read out based on ECT temp. It is only read at Key On. Post fuel trim multiplies this value that is read out. Changing the post fuel trim after start up wont have effect, you will have to restart the ecu/car to have effect. Post fuel value @ ect * multiplier = stored. This value is used as enrichment and then brought to 0 after x amount of time. The duration of post fuel is based on the value of post fuel on Key on. Every etc has a different post fuel value and also a different duration. Feel free to ask more questions

so you added fuel and you went leaner? Just recently maybe a few ROM versions back after turning my car off and restarting after a few minutes with the ECT temps still close to normal operating temp My A/F at Idle will climb to the high 15's. Never happened before but its pretty consistent now. But if I start my car cold and drive stop and go a one-way drip I have no issues. Only after I restart my car with ECT's still warm.
