ive got an escort van thats running a zetec turbo lump and 4x4, its running off a cos L6 ecu! its all up and running now but seems to be firing way too much fuel in resulting in much popping, farting and smoking! the injectors its running are jamsport spec 370cc but the chip in the ecu is one of those autopoint jobs off ebay i think! does anyone know which chip would better suit the injectors or am i barking up the wrong tree?
