Can St170 Run Without Pcm And Cluster ??

08 November 2014 - 01:18 AM

I'm currently fitting a st170 engine and complete loom into my mk4 escort. Then gonna slowly remove extras like lighting ect.

I have the ecu,key,transponder and fuel module unit.

I found out some focus have pcm units that pair to the cluster/dials.

Will I need this also before the engine will run or is this just unproven facts?

Time To Get Stuck In Again Fuel Question (St170 + Mk4 +Oem Ecu)

04 November 2014 - 08:04 PM

Hey guys. Iv decided to carry on with my project. Iv finished up a lot of welding. Battery tray.. fuse tray.. both sills both rear wheels.. ect lol

I'm dropping in the st170 engine and escort Rs gearbox

Because my mk4 was rocking a 1.4 carb. What can I do for fueling ? Because st170 is ofcourse injected and non return system it uses the control module to adjust fueling via voltage to the pump

Can I install a inline pump or do I need a new tank ?
