I have saph running t34:48 grays 3 bar -34 actuator big intercooler updated fuel pump std motor . Had car on comp today And was running 10-11 on co. with Motorsport developments 380 chip .should run 2.7-3 on co can't get it below 8.9.. Any ideas

 

possibly map sensor, mine was doing the same when my map sensor was faulty, failing that a setup would help

 

I have spare map sensors so will try. But co screw on ecu let's me Increase but can't get it lower than 8.9

 

That is extremely high.

Do the usual sensor and calibration checks, if they don't help or find any faults don't hesitate to contact me at work to help resolve the issue with you.

 

No prob James . Only sensor I not changed us the brown water temp sensor . If fuel reg turned up ( over fuelling ) then co goes down to 5.6 . Any advice welcome
