KOKO
I did a key on key off relearn and the truck would idle at about 1200 and real lopey ??? then I shut it off restarted did the same till I unplugged pmd and hooked up other one then changed it back andf it was good?
|
What was the new TDCO value?
Did PMD have a resistor in it? Clear codes before KOKO? Temp 170 f+ before KOKO? Any codes now? |
im thinking it was only about 160 f idk what the tdco was I had no codes before or after and there is a resistor in the pmd I see

The temp must be 170F+ to do the relearn and when you do a KOKO you must have a scan tool that will display the TDCO value so you know if more adjustment is required to get in rang.
stock TDCO values are -0.25 to -0.75 performance values are -1.50 to -1.94 In both cases the negative value is important,it denotes advanced timing while a value that appears posative denotes retarded timing. |
Did you get anywhere with the problem?
|
I never did it again I left it alone I havnt messed with timing it seems to run good idles at about 600-590 the timing is at 2.9 the diesel guy I talked to said leave it? could I move it towards driver side just a tis and koko?
|
2.9 means absoloutly nothing unless he did timeset instead of TDCO?
Even then I would say it's retarded. |
