Rough idle, barely runs 94 6.5td
#23
So I gave up on the db2 for the time being and ordered an aldl cable to set timing with my ds4 pump. I should be able to set it with that engh program but from what I read online it won't go into the mode if there are any dtcs. Anyone know if there is a way to "tune out" the boost solenoid and egr on the obd1 systems? I have dtcs from removing those when I made a manual boost controller and removed the vacuum pump.

You need to have the PCM reflashed ("chip change" on an OBDI).
I think some guys get away with leaving the egr hooked up, but you're already past that point by the sounds of it.
And yes, you need to clear the DTCs or TDCO won't intitiate. Engine has to be up to temp also.
If you can find a PCM in the scrap yard that's already an L65 calibration, you may be able to plug that in and get away with it. That should work, but no guarantees....

I moved the pump around a bit and this is what I got.
Desired inj timing. - 7*
Measured inj timing - 7.4*
actual inj timing - 30.1*
Its still running about the same and throwing cylinder balance fault codes. I used the engh scan tech basic. ( dont have the full program yet) What to do next?
