Hi, im new to using Link ECU as I bought my car from someone else. The ecu was already installed by the previous owner and tuned. After reading the help files, I found out that many of the setting tables are not looked into or not tuned right for example- Charge temp approx, overrun fuel cut, closed loop lambda to name a few.
I have few questions:
1. my overrun fuel cut settings shows torque reduction is 0.52s and ignition retard is 0. The help file says :
Ignition Retard
To help smooth the transition as the fuel cut turns on and off, the ECU will progressively retard the ignition timing prior to cutting fuel. The ignition timing will then be progressively advanced back to normal after the fuel has been restored. Changing the Ignition Retard adjusts the full amount of ignition retard the ECU will use. The amount of time taken to introduce and remove the ignition retard is controlled by the Torque Reduction/Introduction Time setting.
The minimum rate of change for the ignition trim is 5 degrees per second.
Is this a correct setting or the ignition retard should have some value on it?
2. What is the best way to tune the Charge approximation table?
