PCM HAMMER

[ras"86]

On the bench or in the vehicle?

[B52Bombardier1]

Most of us do the copying and writing using a bench harness though not everybody. Doing it in the vehicle has risks of the DC voltage in the vehicle battery going too low or bus chatter noise from other modules interfering with the writing.

My bench harness is entirely constructed of junk yard parts supported by a good 13.8 volt, three amp Radio Shack power supply. A wall wart 12 volt supply is also risky for too little amperage or an unstable voltage. Fortunately, I have never bricked a PCM but it would be a good intellectual exercise someday to see if I could unbrick it.

Bench. All the tunes I'll be doing will be on the bench.

Can anyone advise me what I might have wrong. P01 , tuner pro bin, OBD Link LX, and PC Hammer. Test write shows successful erase and write, but when I try to write I get an error, unable to erase flash memory. Not sure how to fix this issue. I appreciate your help!

[kur4o]

Looks like pcm reboots at some point, Is this on bench or incar and power supply is being used.

[B52Bombardier1]

Your 12.2 volts in the third line down above is on the ragged edge of being too low, especially during the "Write" and erase portions of the PCM Hammer process. I agree with kur4o . . . you need a heftier power supply that can do a minimum of about two amps without dropping voltage. I use a no kidding 13.8 volts DC old Radio Shack power supply that can deliver three amps continuously - no problems.
