Hi, all. Looking for SERT help.

Can I program new values for only engine idle into the ECM of my 2004 DWGI using my SERT?
That is, if I change idle values without entering values in other data tables (AFR, VE, etc.) and program that into the ECM, will only the idle be changed, or will the null values in the other tables (AFR, VE, etc) remain as they are in the ECM, or will they be replaced by the null values?

Thanks for all replies.

You have to perform a complete flash. This means if you want to change "idle" only you must have a copie of the current map loaded (better thought of as a calibration file). you would open that file in tuner mode edit the idle values, renumber the calibration and file name. then write the entire file to the ECM.

Good Luck
