Here's what I got, looks like you started the car and drove, ecu was not ready. Idle 1200rpm, cts 49c, TPS .40 but is ok, Timing still fluxing trying to idle 9-15deg and mafs volts a little high. Looks like cas drops out first, but I don't really no what you were doing, a couple time looks normal than really abnormal. Then mafs randomly spike to 3.~ or 4.~ whatever, with no other input from cas, or tps. The oxygen sensor appears to function normal, but the temp is not ideal for closed loop so it never happens. So running rich in this condition would be normal, we need the car warmed up and ecu taking control of things. Get those pics of the ecu up and maybe a video or 2.
4hour job max to get you running right. You could just remove the nistune board and see if it runs any better.
