So for example if we look at the first value on a stock 330 the lower value is 11.250 pvs° and the upper limit is 12.501 so if the pvs input is between these values it will start to limit the pvs input from the driver.
Hello together,
sorry for fishing up this old threat, but I have an understanding issue:
You did write about "...to limit the pvs...". But I do understand, if the PVS value (of the sensor) is between (take your example) 11.250° and 12.501°, then ECU will allways take one defined value (for example 12.000° -- I don't know the correct value--), isn't it?
The way the ecu uses the ip_pvs_cor_max_rpl_* tables is a little special if we take the first column(12.5 pvs°) as an example.
If the pvs input from the driver is between 0 and 12.5 pvs° this column will be selected and if the pvs input is higher than 12.5 pvs° it will interpolate to the next column.
So when the pvs input is between 0 and 12.5 pvs° this column will be selected and depending on the rpm a different value will be selected from the table.
If the pvs input is higher than the selected value from the table the ecu will control how fast the pvs input rises with the help of the other pvs_cor tables.
I have written a bit more about the pvs_cor function at
