Let me see if I get this straight
This is in a 2000 Focus ?
Duratec engine ?
ITB Bike Carbs ?
The biggest this is ALL Focus ECU have PATS and the 2000 Ford Focus ECU the PATS cannot be turned off in the SCT tuning software , BUT a few of the Duratec Focus codes the PATS can be turned off but I am not sure if the dash in the 2000 can be run off the later ECU
Now if your running the 2000 Focus with the 2000 ECU and your keeping the stock key and switch then I dont see any issues with it working
Sense your going to standalone whey not just make your own dash and gauges ?
