Hello there, from my last question i switched for my mk2 1.8t swap from narrowband apy ECU to a BAM ECU  8N0906018CB 0003

i´ve tried my best to find the correct values in the binary and cross checked from other ECU / WINOLS Demos
What i tried:
Code:
11/17/2023 13:09:19  Scalar:    CDLSH changed from 1.00  (0x01) to 0.00  (0x00).
11/17/2023 13:13:59  Scalar:    CDTES changed from 1.00  (0x01) to 0.00  (0x00).
11/27/2023 14:43:04  Scalar:    CWCS changed from 100.00  (0x64) to 0.00  (0x00).
11/27/2023 14:43:32  Scalar:    CWCSER changed from 1.00  (0x01) to 0.00  (0x00).
11/27/2023 14:47:42  Scalar:    CWCANKBI changed from 6.00  (0x06) to 0.00  (0x00).
11/27/2023 14:51:41  Scalar:    CW_CAN_R_0__A changed from 70.00  (0x46) to 0.00  (0x00).
11/27/2023 14:51:44  Scalar:    CW_CAN_R_1__A changed from 172.00  (0xAC) to 0.00  (0x00).
11/27/2023 14:51:46  Scalar:    CW_CAN_R_2__A changed from 172.00  (0xAC) to 0.00  (0x00).
11/27/2023 14:51:55  Scalar:    CW_CAN_R_3__A changed from 172.00  (0xAC) to 0.00  (0x00).
11/27/2023 15:03:05  Scalar:    CDTANKL changed from 1.00  (0x01) to 0.00  (0x00).

Whats strange to me is that CWCS is on 100, from the definition i found/got it was on 1A48E.

so the DTC´s i get on the bench are:
DTC: P1523 Status: 0x64 Crash Signal from Airbag Control Unit range/performance
DTC: P0600 Status: 0x68 Serial Communication Link (Data Bus) Message Missing
DTC: P0600 Status: 0x68 Serial Communication Link (Data Bus) Message Missing
DTC: P0600 Status: 0x64 Serial Communication Link (Data Bus) Message Missing

Think i´ve found it.

Reading FR is helping me out.
The Value must be 8 at CWCS, so my fault was i´ve looked it wrong. So location is in my case 1A48D and not 1A48E
Also the CW_CAN_R was 1 bit off, and i changed the first wrong.
All 4 must be 0xAC so it starts at
131FE and ends at 13204, and not like before starts at 131FC and ends at
13202  Roll Eyes

little bit more sleep would help me finding my own faults.

give it a try later  Grin
