So some help, please. I have a 2010 Mustang 4.0 and want some advice on how to update the ECU. I looked at buying a VCM from Ford but I don't want to spend $1400 is there an alternative? I looked on EBAY but don't want to waste my money on something from China if it's not going to work.

First you are in the wrong section. This section isn't for questions about your specific car.

There is a section for the S197 with 4.0L V6.

Why do you want to "update the ECU"?

Gonna move this to tech..

Do you mean get a tune to change the tune on the car for better performance?
