While I do realize that water and/or water wetter does work better than a glycol mixture, that isn't the issue. Temps are fine with airflow thru the radiator while moving, and crappy when in traffic. That points to a fan and/or shroud issue. I'll know better after installing the new shrouded fan, which should show up tomorrow.
Also, I think that ECMlink shows higher temps than Pocketlogger. I've been using Pocketlogger for over a decade now, so while the car runs the same temps it always has, I now realize they're higher than I want them to be. I know this because the fans come on at a higher temp shown via link, yet my dash gauge, while inaccurate, is still consistant with readings it has shown for years. I guess I should fully test this by logging with ECMlink and then plugging in Pocketlogger right after unplugging my laptop for ECMlink.
