Maybe something is wrong in justinve 5120 hack file. I verified all maps and scalars from your xdf from your project and they are correct, multiplied or divided by 2.Hope not missed someone.
There could be things missing, since ME7.5 has some significant diferences
One thing that really bothers me and I haven't got the aswer is that this hack is for 5bar map sensor and since stock is 2,5bars I understand that we need to divide or multyply by 2, but since we are using 4 bar sensor, which is like 80% of 5bar, so maybe it would be reasonable to multyply/divide tables by 80% not 100%
This is mixing the 5120 hack with change in map sensor. Do not conflate the two. They are two *separate* changes.
Do one, then the other, independently.
If you have to
make sure the new sensor works in an OEM file with ONLY the two pressure sensor *map* changes for that sensor, not ASM
make sure the *OEM* sensor works properly with the 5120 hack (verify the 5120 changes - ASM, 2x&1/2x axis changes, map changes)
Then make a third file with both changes, where the adjustment for the new sensor is again ONLY in the two pressure sensor maps, not ASM or axis changes
