Respected Administrator：
Hello.
Are FXTH87 and FXTH87E codes(.s19 file) compatible?
If I can't use FXTH87 code(.s19 file) directly on FXTH87E, where do I need to change it?

Hello LiuKai,
The FXTH87 and FXTH87E are different mainly in the pressure range depending on the part number; here you can see it clearly https://www.nxp.com/docs/en/product-selector-guide/FXTH87A4FS.pdf
We recommend you to check the documentation available regarding the Embedded Firmware in order to know what is inside each TPMS sensor; in this way you can see what should need to be changed:
