How do prevent CEL after turboing your yaris

[BoostedTRD]

I will be going turbo soon and wanted to know how to prevent CEL. When I had my turbo Honda I used a MAF sensor to trick the ecu and hondata also helped. So what did you guys use?

You should not have a check engine light on after going turbo. If you remove the stock cats you will but can easily be fooled by moving the o2 sensor out of the exhaust stream a little.
