Hi, I have a willem programmer and I tried to use it with a 27c128 EPROM, no problems programming the EPROM, I used it to chiptunning my car! it work fine for a few days and then stop working. Tried diferent EPROMs (27c128 and 27128) and always got the same problem.
Does anybody know if the EasyPRO 90B work fine with the 27c128? is it reliable to use with chiptuning?
