Yea disconnect the battery. I have never seen a car where holding the trip button did more than just diagnostics, thus I think the whole "reset the computer by holding the trip button" is just a myth.
Next time.....

do me a favor next time you are out running around town in the rain... maybe a little stop and go and some highway. could you let me know what the h20 temps run.
also as a 70 mph cruise what the maf reads ~.
btw. the beta 2.1 i think it is allows 9 gauges.

Looks like coolant was 179F cruising at 70 MPH. Temps swing to 184F in town, and hit 208F before the thing started cooling down. Outside temp was 60F and inlet air temp was 68F. As for the MAF reading at almost 70 MPH on cruise control, looks like 38.62 grams/sec.

I've hit 210° or so if I idle for long periods of time at ambients over 90°.
You can see 225° or higher and still be alright since the coolant pressure is so high.
You just aren't making peak power and are closer to the knock point.
LTFT probably won't be affected much by your coolant temp, though it might figure into the temp control strategy. I dunno.
