Thread dig, I've been playing around with a pim today and mapped out where & what values are used for all the settings.
Got cocky and blanked the chip to try a write 1 of the files i pulled off... & it fails. Using a willem GQ-4x.
Tried a bunch of different versions of 93C46. chip itself is labelled 93C46W6

Re: VZ PIM
i had a exp2023+ device on my desk that come with some stuff but since i dont have a cd/dvd reader in my computers any more never used it to read software.
bit of googling and got the software, it worked and i now have it flashed to a good source again.. not that it bothered me im about to pick up a 2nd hand unit from fb marketplace. haha

I have 2 Gq4x units, one with firmware version 1.30, the other with 2.20, the one with earlier firmware fails to recogniseVX L67 Getrag wrote: ↑Mon May 27, 2024 7:31 pm Yeah it seems the ponyprog is better than gq4 with eeprom write stuff like this… but also need to have a good quality aligator clip!
or flash without errors more times than the later firmware.
Did a voltage diagnostic test on the earlier one, failed 2 tests, later one didn't.

Re: VZ PIM
Sneak peak of what i'll finish off & then upload the xl file here again.
I'm hoping that there is a specific value that will enable the reverse relay output on the pim without setting it to a 5l40e.

Re: VZ PIM
I feel like around that 0x70/71 location, was the number or resets.. I think??? Maybe 75/75?
You'd know straight away after doing a reset.
Theres also a counter for how many incorrect immos entered.

Re: VZ PIM
You might be correct. a few of my reads did have data in there, then it went back to zero.
since this in a vy & im not doing any linking it might have reset when it took me a few goes at recovering the bin.
the willem reads the data bitflipped but the ezp device reads it direct.

Re: VZ PIM
ok, i suspect there is clearly a checksum going on. today instead of changing multiple options i just changed 1 value at a time and read the binary out.
4x05 is the checksum value See the xlsx file & zip containing read pim data. Anyone got a clue as to working out the checksum?
