Yes, 100% clone... Bought it before years as reworked...

I had only ecu, not car... I read flash/mpc also several times... Each time same... Only Eeprom was not same... Why... Really don't know...

well i read on bench over 10 times (and write a couple) the eeprom of one marrelli 6f3..... always with success...

and i compare the files..... you have right..... always a bit different like count something.. (44,45,46 etc) but only that different....

What nice small power source are you using Panathaole?

**figani** · 16th December, 2018, 09:14 AM

It's maybe a counter...

As I wrote, after that open it and read by Ktag, several times... Every time the same...

At the end... Solder down Eeprom and read it...
Compare with Ktag, and same...

Compare it with V18, and not same...

Anyway, i have read-write many times eeproms of that kind of ecus, never had any trouble.....

i have a fiat right now, i read eeprom via OBD a couple of times to see if there any difference....

what difference you got comparing mmps and ktag eeproms?

is like the eeproms that i have upload?

Marelli ecu are capricious, the best way is to do full backup on bdm with ktag, then flash obd with kess or mpps

I have take after brick a ktag backup...

And I have the backup of the mpps....

Thanks.......

Hey guys, I have MPPS V18 that I am suspecting has an internal short. Those who have one of these would you mind hooking up power to it and checking voltage on the Kline? I am getting 12 volts which I suspect is incorrect.
