Title: Strange behavior when altering axis for LDRXN and KFLDRL Post by: lphsail21 on January 02, 2018, 04:57:00 PM I am working on a tune with a 518AK v4 ECU that needs the RPM axis for LDRXN adjusted and the LOAD axis for KFLDRL changed as follows:
Stock LDRXN RPM Axis (Conversion X*0.25): 1000.00 1500.00 1750.00 1950.00 2250.00 2500.00 3000.00 3500.00 4000.00 4500.00 5000.00 5500.00 5700.00 5900.00 6100.00 6700.00 Modified LDRXN RPM Axis (Conversion X*0.25): 1000.00 1480.00 1600.00 1720.00 1840.00 1920.00 2000.00 2520.00 3000.00 3520.00 4000.00 4520.00 5000.00 5520.00 6000.00 6520.00 Stock KFLDRL Load Axis (Conversion X*0.005): 30.00 35.00 39.00 45.00 50.00 60.00 70.00 80.00 90.00 100.00 Modified KFLDRL Load Axis (Conversion X*0.005): 0.00 10.00 20.00 30.00 40.00 50.00 60.00 70.00 80.00 95.00 When I apply the changes and save the BIN file, everything seems fine. However, after I change the load axis, the RPM axis is suddenly no longer correct, and goes something like 500.00 0.00 1500.00 3200.00 etc, which makes no sense. If I correct the RPM axis again, and save, then the load axis suddenly changes to 29.60 32.00 34.40 36.80 etc, which again makes no sense and there is no reason it should change in the first place. What is going on here? The factors and conversion are correct as far as I can tell, but these axis' refuse to both change and save together. One or the other can be changed and saved, but trying to modify both and saving bin results in random corruption or wrong computed values. Can anyone make a suggestion as to what could be causing this strange issue?

Maybe post up your file and definition or ols?
