Hi guys, i read IROM from my mercedes ml270cdi... its EDC15C6
I want to dissable checksum in ecu, because i want to put in moates flash emulator (like ols300)
I have my irom changed (my brother work for me) but i CANT WRITE back to c167
Im connected with old kkl cable over kline.
I thinkink about bad settings SYSCON or BUSCON or i need connect directly with Rx Tx and bootstraps pins?
Or i need new c167 with free OTP memory?
Thanks in advance
