right im not sure if i need to adjust my 2wd cossie fuel reg on my zetec engine on throttle bodies its running ST170 injecters im sure the car it come from was running stage 3

thanks

 

i would cheack to see if the fuel presure is to high or low dont just leave
it

 

how can i check if its high ? lol

 

You need a fuel pressure gauge, the knowledge behind what pressure the ST170 is meant to run, what fuel flow you need to get the correct AFR for you engine, and also if your pump and wiring can handle what you ask of them

 

theres nothing special about the reg, should work on any EFi car

 

bttt surly some one nose what presser i need ?

 

Luke, as you have a car that is totally non standard in terms of hte management the asnwer to what pressure you need is whatever it was mapped at.

but personally i would recomend around 3 bar

 

thanks chips will sort out my edis agen and have a little try when i got some petty in it lol
