Hi I think my ecu Walter coolant sensor is gone car runs lumpy and wean I look at it on my apexi power fc it gos up to 50 and then down to -24 so the car is over fuelling and over heating the car is saying its rite but my defi gauges are saying 110 so hot am I correct on this or can I be missing some think please help thanks

 

Defi run off different sensor, ecu only uses CTS, the fact your FC is all over answers the question.

 

This is what I was thinking so will need to fit a new one and check the earth to try and sort this out
