New result. Fan start temperature was lowered to 95 degrees.
There are two maps in Volvo BINs. They can be found by next bytes sequence
6   64   203   204   215   221   222   0   0   20   180   221   221
Axis values is motor temperature. Multipler is 0.75 offset is -48. By lowering these values start fan temperature can be lowered.

Also work on 5120 hack almost finished. I was able to run car with this hack. Boost PID works propertly. There is a small problem with mixture calculation. I think that this problem relates to wrong difference between fuel and manifold pressure. So I need more logging to debug this problem.

If someone wants variables for own logger, most should be in VIDA database.

Simple query:
Code:
SELECT tbv.fkT155_Scaling, tbv.CompareValue , b.*FROM carcom.dbo.T141_Block b
join carcom.dbo.T100_EcuVariant tev
on tev.identifier = '08658507  H'
join carcom.dbo.T150_BlockValue tbv
on tbv.fkT141_Block = b.id
WHERE
b.name LIKE '%PLSOL%'
AND
b.fkT142_BlockType = 5

just replace "PLSOL" and "08658507  H" (ecu number)

Would anyone know where AIMV is in this file? I have swapped in a six speed manual M66 trans from a v70R into an XC90.
I was not sure if It was required to be changed as the speed sensor is picked up off the ABS.

Thanks.

Judging by FR, you can leave it unchanged (see GGVFZG).

You may have to fix NVQUOT1O,NVQUOT1U..NVQUOT5O,NVQUOT5U (see BBGANG).

Thank you for the reply, I had already changed NVQUOT 1-6 to allow for the tire size difference from the donor vehicle (25.4"  V70r) to (29.1" Xc90)
Hoping I have got it close enough .

In this case, it is not the dimension of the tires that is important, but the gear ratios of the gearbox.

According to my calculations, NVQUOT can be left standard.
