You can rent the dongle from Lockeeood for around 50$ (we rented it about 8
 years ago so price might have gone up).=C2-

> The yellow caution light is blinking. The warning lights come on and go 
off as they should when the tcu is powered up, the waste gate cycles thru 
properly at startup as well. With the engine running the yellow light is 
not blinking at idle but starts to blink at about 2300 rpm and continues as
 rpms rise, go below 2300rpm and the light goes out. With the engine off 
and the turbo powered up the yellow light also is off at idle throttle 
setting and if I advance the throttle the light starts blinking and will 
stop as I pull back. So it seems that the throttle sensor is sending a 
signal to the tcu as it moves. But what is the issue=3F Sensor, tcu, other.

remove the tcu and send it in for diagnoses. Anybody had this issue=3F I 
have searched this and have seen it discussed but the threads just end with
 no resolution, so I know I'm not alone out there.

is adding boost too soon for the throttle setting which also points to the 
throttle sensor.

pc in dos! So I can't plug in my pc and test it myself. Anybody know if a 
dongle is available and software=3F Maybe Lockwood or=3F
