Ebay, http://www.ebay.com/itm/SIVAVA-Wille...-/251934829226 You must have a parallel port on your PC to use this one. I use this to program and erase winbond EEPROMs that you find on ebay and other places

Moates.net https://www.moates.net/burn2-chip-programmer-p-197.html Works great for flashing and erasing genuine SST27SF512 chips. Will program but not erase the winbond "fakes" that are on E-bay. Get your chips from Moates, MCUmall or Xenocron.

These are the two I own. There are plenty of other programmer/readers out there. The BURN2 is the easiest to use with TunerPro. TunerPro has built in support for Moates hardware. If you plan on tuning this vehicle, you may want to read http://www.gearhead-efi.com/Fuel-Inj...ght=7747+flash This thread is about modifying a 7747 but the 8746 is the same as far as the socket install. You have to be extremely careful when you remove the old socket. If you damage any of the traces in removing the original socket, it can be a pain to repair. Read the above thread thread carefully. It will save you some grief. There are several tuning threads on this site. I advise you to read and try to understand the process before you even attempt tuning. There is a wealth of information on thirdgen.org in DIY Prom http://www.thirdgen.org/forums/diy-prom/

Hope this helps,
