EOT and ECT 04MY, results
I just got my ScanGauge II installed, it was a gift for Valentines Day.
I set it to monitor the EOT,ECT, and trans temp and after warming the truck up to operating temps my results are as follows:
Outside Air Temp: 37 Degrees
I never seen bigger than a 9 degree gap.
I recently did an EGR delete and switched to ELC in December of 2010. Everything looks good to me, just wanted to share my information. The Scangauge II I got from Ebay for 170 with a mount.
