can anyone point me to the right direction in regards to deleting the ews system on a MS40.1 5Wk9 003 found in the 95 2.0L M50B20 320i??

something I can wire up myself would be fine or if its software flash, works too. Looking for a DIY option on the cheap or whatever works

Thanks

I believe 40.1 uses ews1. I think it needs both a chip delete as well as a wire snip.

If you have 5WK9003 you can flash it with 5WK9002 and Immo is off. Bridge the 2 starter wires in the plug from immo box and everything works.

Ive got a problem while flashing 02 soft to 03 ecu. Always ended up with buffer error at 5c01. Im trying with mini pro. Any suggestions please?

test another chip, maybe driver fault, maybe tool fault, maybe maybe maybe.

programmer should be ok it works on all other chips. Strange is that I can flash back ori file without issues...

Got another 28F512...

no time for new chip :X they arent available in my country so it will take a forever till it comes. Dont you know where is the isn in that ecu?

Im attaching original read.

And thank you lambda for your patience and help.

Why dont read with INPA under configuration

I have only ecu on table without a car and I cant make it communicate on bench :X

maybe you can point me a bit with the connection. I used same pins as for MS41 bench + L-line pin 87. Its not obd2 ecu so I cant use dcan cable. I used oem icom next for this but no connection. There are two possible causes:

1st Im missing some gnd or +12v on ecu because when I switch on PSU no amperes taken by ecu it self.

2nd I have to reconfigure protocol in ediabas for ADS. However I though icom could proces the ads signals itself because I can connect to ads cars just fine like older e36 but not on bench.
