I pulled the prom chip (AT29c256) from my p75 ecu to read the contents so I would have a backup of the tune. After downloading the information I saved the information in a binary format (see attached). I then proceeded to burn a new chip (SST27sf512). I have tried both the old chip and the new chip in the ECU but the car does not run. It will start up for just a second and then die out. Could I have screwed up the information on the chip just by reading it? Thanks in advance for any help you have to offer.

On a side note, if I change the extension on the binary file to ".re4" I can open the file in Smanager.

The file opened fine on this end.

Was the car tuned with Romeditor 3 or Romeditor 4?

I thought it was tuned with re3 but I cannot be sure. Is it any hint that I have to change the file extension from ".bin" to ".re4" to have smanager open the file? Thanks for the help.

Check with your tuner, but it allows you to import the bin file into RE4 without any problems. Just check your parameters.
