    Open loop, O2 very little variance from 450mv stoich and 2 minutes into log 20* w 4* knock retard bouncing things around. Volts seem a little low...code 43 knock sensor circuit failure.

    Went back and read last 2 pages...is O2 sensor installed? How much initial timing you got at the crank? Is this engine purdy much stock meaning suppose to run on stock tune or did a lumpity lump cam get installed?

    Don't know much if absence of an 'E trans causes issues, helping a buddy of mine 4.3L BJYL 700r4, found a trans error fuel cut-off parameter...so wondering myself??? Turned off a lot of trans related stuff trying to dial in tune.
