will cosworth yellow injectors work on standard fiesta turbo managment ? cheers

 

i cant remember what impedance injectors the FRST uses,, im sure they are different to the low impedance of the "yellow" injectors you are talking about

by standard, do you mean without a remap? is so, even if the impedance do match, all you will do is be rich EVERYWHERE. as what you have done is increased the fuel flowrate to the engine by the percentage of your injector flow rate ratios!

 

currently im using beige injector with a 195 chip and have a up rated fuel pump fitted but want to upgrade the injectors and change to the chip

 

no they wont work
