www.intronics.com is a different intronics. I don't know the exact history but several years ago there was an intronics in KS that made a pocket programmer. Their website disappeared and
www.xtronics.com appeared with the same products and I think the same street address. Look at
http://www.xtronics.com/memory/EPROM.htm The pocket programmer is cheap and flexible because it uses the parallel port, but there are lots of other, more expensive, better programmers on the market.
You have two choices: buy a package (more $, much faster) or piece it together yourself. There is a commercial chip editing program called Tunercat, that BM Computers is packaging with a programmer, blank chips, and support for making chips for the tr's, called T6Tuner (I think - sorry if that's off a little), for barely more than you can buy the individual parts. Read some of the older threads in this forum and you'll find links and info. Or you could get your own programmer and either buy tunercat or go to
www.diy-efi.org and get winbin and the 7148.ecu file I uploaded for free, or just use a calculator and the hex editor that comes with your programmer. Get the promdata.xls spreadsheet and rom/eprom dissassembly from
www.gnttype.org no matter what and start reading. I started out with calculator and hex editor and now use winbin so I'm not a customer of BMC but I've heard very good things about them and I think that if you want to get started making chips the fastest that's the way to go. If you want to learn the internal workings of the ecm in gory detail then go my way
. Either way, I'll repeat: get the promdata.xls spreadsheet and rom/eprom dissassembly from
www.gnttype.org no matter what and start reading, because you will need to know some of this stuff from the beginning.
