Problem burning up D8
Posted: Sun Oct 30, 2011 7:55 pm
All,
I have been very successful in turning D8 into a resistor with values ranging from 180 - 450 ohms. This causes the converter to lock up very shortly after the shift to second and remain locked until the shift back to first (very harsh shifts to say the least). I believe that it is probably being caused by an inductive kick from the tcc circuit (4l80e pwm tcc). I have added a 270 ohm resistor in series with d8 that will hopefully protect it but still allow it to protect the transistor. Does this sound reasonable?
Also, everything that I have read shows the gm tcc being pulsed with a frequency of 30 or 32 hz but tuner studio will only allow a maximum of a 10.888 ms pulse period. Is this something that I can change in the .INI file without causing any problems in the code?
Thanks,
Chris
