I made an Opel Zafira 2.0L with y20dth engine hybrid control unit PSG16. Connect with the tricore cable CAN-L and CAN-H directly to the pump.
MPPS V18 has read the PSG16 in 2-3 minutes, to write 7-8 minutes.
Make sure you have enough voltage when writing because the fan starts running (or disconnect it before write) if something goes wrong here you’re f**ked.
MPPS calculates the checksum automatically all perfect.
I use MPPS v18 from China are worked.
what do I have reworked? I have purchased the file firmware , or unlock?
Do not cut the green and white wires.
Simply make a cut around and join with the MPPS cables.
Ensure stable voltage during writing.
The reason to rework mpps because some cheap MPPS china need rework. One comes with missing components and different resistors are installed with red marks below:
D1 = PESD1CAN ESD protection
U4 = PRTR5V0U2X
Enlarge it and see what’s missing.
You must solder K line driver in empty U8 place not in U12 where is Lm2903
Here is schematic if it also helps
After that, the reworked MPPS china clone:
