Hello folks. I have one RS turbo s2 with one blue red black ecu . The car runs fine until 4000 rpm after that cut . I already change knock sensor, change distance in weastgate to change turbo pressure many things. Anyone already have this issue ? I don't know if is due to turbo pressure or other thing. Anyone can help me ? best regards from Portugal

 

if turbo pressure going over 10 psi it will cut igntion.on a standard chip

 

First of all thanks for your help. Ok but if is under it cuts to ? Because if I disconnect the MAP pipe to ecu the engine goes until 5000 rpm it's normal ? What is the other sources to ecu cut ? Turbo pressure , knock sensor and more ?

 

Would expect the map sensor to be the source of load.

 

only the boost pressure ? The cut can't be related to another sensor ?

 

From memory yes, it's been 20 yrs + since I had an RST
