    Will Optical bump change TDC offset if relearned?

    I changed the optic bump back to stock setting and my timing dropped down from 11.1 to 10.0 and i relearned the TDC off set at 6.1 then in the time set mode the base timing was about 4.5 and setting code 1214 TDC offset so i turned the ip back some and got it at 3.5 with the actul timing at...

    Turbo Downpipe Show 'n Tell

    I made a 3.5" down pipe for my 6.5 i started with a used duramax exhaust and a 6' straight pipe and made it 3.5" straight piped from the turbo to back side of the tire and its not loud at all with the turbo!:D :thumbsup:

    IP Install Question

    the timing will be advanced when the engine is cold. I let mine warm up to 75c ect on the scanner and then exit engine data and go in to time set then the des will go to 0.00 and set the actual about 3.5 degrees timing then you can do the koko (throttle to the floor key on for 45 sec then key...

    Will Optical bump change TDC offset if relearned?

    I'm wondering if the optical senser bump advanced the TDC offset some but not the base timing because its still at 3.5 in the time set mode But when i exit the time set mode my base (actual) timing and desired are at 11.1 i read it was to be about 8.5 degrees:rolleyes:

    Will Optical bump change TDC offset if relearned?

    :dunno Will Optical bump change TDC offset if relearned? I set my actual timing at about 3.5 in time set mode then i have 11.1 desired and 11.1 actual timing and the snap-on mt2500 scanner reads the TDC offset as 5.9 i've read that this scanner reads different and that -1.94 reads 5.4 so...

    97 6.5 changed ip now blows white smoke code 216

    Ok i found the problem the valve in the advance piston stuck due to varnished fuel or contamination from moisture sitting in the bottom of the pump. I had to take the injection pump back off to get to it and the advance linkage was moving but the valve in the advance piston was stuck...

    OK I checked the volts at the connector that plugs in to the stepper motor with the key on 12v, 4v, 12v, 4v, then with the engine running all four have about 7volts but both the stepper motors i have do not move with the key on or running. The advance linkage will move about 3/8"

    The stepper motor is not moving to advance the timing so the actual timing stays at 3.5!

    97 6.5 changed ip now blows white smoke code 216

    I'm north of wilmington 10mi in Hampstead. I checked the timing with a Tech II and the TDC offset was -2.44 so i moved the pump some and got the actual timing to average 3.5 going from 2.8-4.1 and a desired timing of 11.1 and i got the TDC offset the land on -1.94 it had a range from...

    97 6.5 changed ip now blows white smoke code 216

    I got a snap-on 2500 and set the timing close to 3.5. It was changing from 3.0-4.0 i guess the stepper motor does that. actual inj timing was about 11.0 and desired inj timing about 3.5 I set the TDC offset to -5.4 I read that the snap-on scanner reads different and that -5.4 is really -1.94...

    i change the stepper motor. but that didnt change the smoking i moved the ip to the drivers side 3/16" and that helped the smoking a lot but its missing and smoking from 2000rpm and up. does anybody have a tech 2 scaner near wilmington NC?

    I have a 97 1500 6.5 turbo and i've changed the injection pump because it stopped running with the old one. Now it runs with the newer pump but its blowing white smoke and has code P0216 -- Injection Timing Control Circuit What is Injection Timing Control Circuit? And what can i do about it?

    97 6.5 no start no fuel at injecters speedo bounce like a tach

    I made it home from the trip before it died. i'm so lucky I changed the fuel filter after it died then i primed it and checked the fuel press its 5psi and got good flow when cranking
