Shouldn't have a problem writing on the bench if the immo is offed. Kess should work just fine. Or you can bootmode with kess too. Both work without issue.  Make sure you use the 400bb euro protocol. Kess does checksums too btw

Hey Guys! @Risky @ Marty!

Thanks for your reply dudes! ^^

well i met a programmer from GR in dk forum, exchanged numbers and talked a bit about this isue!
        THE RESULTS ARE:
KESS v2 can read and WRITE partialy the ram chip aka flash aka F400bb via OBDII without touching areas of the eeprom!

My 21 succesfull Write logs are the proof! ^^

even thou my ecu is messed up right now -car wont hold idle rpm-
i managed to program the ecu without immo locking! and that was my struggle all about at 1st place...

on the other hand, ADS EGR REMOVER sucks! at least for using with dumps from kess, but i believe the experienced users already know that!
i made 2 dumps using this programm from my ORI file, one with ADS EGR OFF and one with ADS LAMDA OFF and none of them worked properly -just sayin for future member troubleshoot- !!!

I flashed the stock ORI file back to ECU but i cant make the car run properly!
as i said Idle RPM wont hold steady resulting car go off every time the engine stars... and i mean EVERY SINGLE ONE

scaned for DTC's with Delphi but no logs, no MIL nothing! exept real time data that indicates a rather strange thing,

When im holding RPM completly steady Cylinder 4 misses all the cycles till my foot messes with rmp and the Delphi indicator sets to 0 and all over again...

Hmmmm... maybe the moded dumps i flashed where so f bad that my ECU went loco!
 car btw runs when you cruize in the road but its a bother every time i stop at the trafic lights to start car again.. :/ bad for starter and battery too! also burns gas like hell!!! and the emmisions, duuude the emmisions made my eyes bleed when i tried to start the car inside workshop...

Well! a small step for a young engineer a giant leap for a workshop busines! ^^

@Marty

Engine code is BCA 1.4l 16v  75hp

but for ecu software i must log in with kess again and im feeling like a turd from exaustion... just got home from the workshop i work  :/
ill write you tommorow about that

Brief update...

the first time i flashed ecu was with a Lamda OFF but didnt worked correct because i choose a programm to do the job and not manually remove it with Winols or other professional programm resulting my lamda 1 sensor that does all the job with the air/fuel ratio to not work and overheat calalytst witch broke down...

the good thing is that kess works, ecu works, immo didnt locked! yeay! ^^
 with 20euro i can remove the catalyst at en exhaust center.. .

i will brief again tommorow!

@Fukenbroken

Goodmorning from GR mate!

yes... i will agree.. when a rookie tryies to do a profesionals job, terible things happen indeed!
but, nevermind... golf is the first car i tryied to tune... overall its a broken catalyst... not an engine, not an ecu just a catalyst...

from my point of view this went really good! flashing went good, car worked for some runs just fine then cat brokedown...
Aw well, shit happens right? ^^

funny story, when i flashed the lambda off i made o long log run... till my idle went really rough... returning to workshop flashing back original map made car work like a charm till the demon in my ear whispered "Flash EGR OFF" witch i did and after some more runs overheat broke cat... thats prety much the whole story...

are there any manual about what nefmoto is capable of? like a tuning suite or such?

sure... but! have in mind that i read the file with KESS clone
im begining to have doudts about if it checksums corectly! maybe you can check it out?
also include 2 files, both are from my car before any ecu writing... can you also check if they are the same? ECM titanium checksums them with the same number! cheers!

shoot! was hoping chinese could do 1 freaking thing without messing up!
damn! now am 100% sure that i messed up my ecu...
if reading checksums wrong, imaging what write will be :/

dude! now im really sad! :/

maybe trying change the value of the pullup resistor fixes the bad checksums?

how you chck the sums in winols?? is this original version?

Both files say original so I'm not a 100% if it's the original or not. The other file had no checksum errors so I'd assume that is the original? As far as calibration changes I didn't check sorry. I just imported the version without errors and built a small map pack off that
