I have a UV Lamp - can you recommend me a cheap programmer ? I use it only for my own cars / hobby.

Are the ECU Maps and the Immo Informations on the same eprom in this control unit ?

maps and immo are on different chips ... maps DIL28 (probably 87C257) chip and immo on small 8 pin eeprom probably 93c46

MInipro is a good cheap option.

You can erase EPROMS (not EEPROM) only by UV light - thats no joke :-)


Can somebody tell me, whether the IMMO is located in the EPROM chip and disableable by flashing the EPROM chip ?
