Help with correct ECU ID?
I’ve been searching everywhere but can’t find a way to ID my ECU, or work out the correct part for my truck.

Can anyone decide the sticker on mine, and why does it have 2 boards in it?

Can’t find YB anywhere

What’s the 2nd board do?

What is the application? What year, what model, what transmission what engine? And what version of the engine if there are different ones (like California or Federal emissions).

They all have two boards.

What are you trying to do?

My 86 bronco is a RX calibration.

There's really nothing in the numbers that the end user needs to know. Unless you're doing some really in-depth diagnostics and trying to Tune it. But you need special equipment to do that.
