Hey guys Recently my stock coolant temp gauge that Im aware is no longer functioning has gone from the normal 1 bar that it showed since tuning with EMS, to full hot all bars and the red. Should I be concerned? Any thoughts? Did some searching but have found nothing like this.
So to sum, for 2 years after Jeff Evans did AEM EMS the stock temp guage sat at 1 bar, now out of nowhere its full hot all the time...
Any help would be great

PS,
the car's collant temp is normal

Thx

 

I feel the water temp reading is more accurate than stock with the ems. I think the stock ecu overrides the temp sensor for the first minute, because now my temp sensor jumps to 2/3 within twenty seconds from a cold start (head heating up rapidly with the air pump and the thermostat is closed). then goes normal once the thermostat opens and coolant from the radiator stars flowing

if you have the first series EMS, the factory gauge will no function properly unless you have bought the modifry temp fix.
