This post show guide on how to use WinOLS to tune ECU map for Volvo 850 T5 Motronic 4.3 ECU. The Volvo 850 T5 uses a Motronic 4.3 ECU. This car has a 28F512 EEPROM inside which is soldered onto the board.
To tune this car by yourself you need the following:
1.New 28F512 chip(not necessary, but better) cost around 7 euro.
2.DIP32 socket cost around 1 eruo
3.A programmer which can handle a 28F512, I suggest a GALEP 4 or 5, but others also will do the trick. Please do not use a Willem programmer, they just screw your file up often!
A used Galep or similar programmer costs about 100-200 euro.
4.Edit software like WinOLS, TunerPro or ECM2001. TunerPro is freeware and able to do
