    i think i see the issue with the AFR conversion already though....

    the early 3800 stuff may work a bit differently than expected, i imagine "closed loop correction" takes place of the INT value.

    okay, this has the AFR fixed and everything else i looked at seemed to act normally. the fuel usage and distance accumulators look to be very small capacity and roll over a lot.
