Hi,
did you ever had a issue with ecu that you got the eprom checksum error...i am running RP lab p8 ecu with map editor and i got this error while connecting with laptop and now the car cant start at all and i also cant connect it with laptop...is the ecu dead?
thanks

 

Probably a corrupted eeprom. Try writing the calibration to it again.

 

i cant even connecting it with the laptop...thanks for reply

 

In that case maybe the eeprom is faulty. Try swapping it for a know good eeprom.

 

i have sent ecu for repair...just wanted to see if anybody from here had the same issue..thanks for reply..looks i am the only one running with this ecu ....didn't last long so it is a not good choice..
