well its the best and easyest way ...... dont go the mk5/6 loom way as its to much work and restrics the engine
the mk4 1600 efi loom on the 1800 zetec 1 works well and 2 gives better power and touqe
also better for the mot as you have a higher emisions level then if you was using the mk5/6 loom and engine with the cat ......
let me know what where and when lol when your ready plus if you look in the engine tuning section there is some poasts about the zetecs and whats needed and so on .....
