stock 4.8 and manual nv 3500 swapped into 89 jeep wrangler.
drivetrain, pcm and harness all from swap truck.
wideband not hooked up for drive, but i know fueling is good.
in my tune i have timing for "launch". but issue was present before that change.
hanging rpm and timing dropping off has become more pronounced.
failing cam sensor? crank sensor?
ive posted before about this but have not gotten much response.
i believe i have have everything for timing logged but cant see where its pulling it.
base advance still good but actual goes super low(negative).
towards the end of the drive is the hanging rpm.
when i give high throttle at low rpm it hangs to the point if i push the clutch after letting off the throttle the rpms will rise.
have attached log file as it sits and a drive home with lots of documented faults.
if you think i should log something else please let me know.
