Hey guys recently got the stage 2 RPM tune from MarioKart for my R56. Car runs great but after driving for approx 15mins I get a CEL saying my coolant temp is too low. Car temp stays between 180 and 190 which is what I thought it was supposed to be after the tune. It runs great no issues. I clear the code and the light doesn’t come back on. I live very close to work and the light only comes on occasionally. Usually when it’s a longer drive. Any thoughts would be appreciated. I’m thinking sensor or thermostat.

 

Stupid questions first, have you checked the coolant level?

 

I have checked the coolant and bled the line and also their isn’t a leak etc.

 

Than I would be contacting Mario if this is an issue you've only experienced after a tune. Yes, the tune will change the coolant temp target to 190F I believe. And if you can maintain that but the car is giving you issues then it might be a problem with the coding. Mario is good with customer service though.

 

I have contacted Mario and he is recoding it now. Yes he is super helpful and has great customer service!
