I have a problem with my Tacuma ECU. Randomly MAP sensor stalls at 115KPa. Triple checking sensor and wires shows that it works and I suspected that ADC in ECU is problematic. The easiest way to repair is to get spare ECU, read flash (AM29F200BB – chip#1) of old one and program it to new ECU.

Huh ???
In my work I have Rittal CMC-TC device to play with. Unfortunately it has unusual serial port. After half day googling with my colleagues we managed to find damn pin-out.

This device is linux based and it is full with funny things.

Just add single to kernel boot parameters, then passwd and write-config.
That’s it.
This smart card seems to support only 1024 bit key length and certificates in der format with .cer file extension.
Steps to generate and import keys:
1. generate private key and self signed certificate:
openssl req -x509 -nodes -days 3650 -newkey rsa:1024 -keyout privateKey.key -out certificate.crt
2. convert certificate to der format with cer extension
openssl x509 -outform der -in certificate.crt -out certificate.cer
2a. or optionally pack key and certificate in single file
openssl pkcs12 -export -out certificate.pfx -inkey privateKey.key -in certificate.crt
3. import resulting file/files
