Some data that may help
7E0: 03 22 03 70 00 00 00 00
7E8: 05 62 03 70 01 93 00 00
So the pid is 220370
On 7E8 return the 01 93 are the changing bytes

The 01 goes no higher than 04
In my logging list I have 01, 02 ,03 ,04
Its like there’s 4 different sets of hex depending on the boost range
I have seen some of them like this
01 C3 and further down my log I will find one thats 02 C3
I have seen a few like this

Have you tried equation like
Int16(A:B) or (A*256)+B?

Boost = MAP – Baro()
