Hi! Im new here, read all thread, but Im not so much expirenced in using WinOLS and therefore Im asking for help or hint.
According to the Prometey's post #1439 about decreasing fan start temperature , is there anybody who can tell me what address is this sequence of bytes placed?
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.
I have searched this sequence, but without any positive results.
And the second case: what address is ESCONF for 20FWHJ ? I cheched at 0x1260E but it seems not to be correct address
Disabling rear lambda with ESKONF for 50WRHJ software.
ESKONF is at 0x1260E. Default value is 0C 00 3C FC 00 FC 33 (7 bytes length) I may be wrong about lenght it can be 6 bytes.
To disable rear lambda and rear lambda heater diagnostics you need to change ESKONF to next: 0C C0 3C FC 00 FF 33
I checked pre facelift cars and non R software. It looks like the bitpair pattern is the same. Second byte must be changed to C0 (6 and 7 bits must be set). And six byte's low two bits must be set.
Thank You all for any kind of help
