Whoa! Definitely double check your wiring install. 266 degrees F is way too high. You would do damage to the engine at that temp., like, not running anymore damage. Did you install a new OEM ECU coolant temp sensor? Those things go bad from time to time and will send wacky info (temps) to the ECU. Since this is where the HKS unit reads from, it might be the culprit. Replace it, it's only $15-$35 depending on where you buy it. I believe the DOHC KA ECU temp sensor is identical. Check SR FAQ's section to verify. let us know if that works or not.
