This is our new release of a replacement to the 28 pin SST Chips that many of us DIY Honda Tuners have been using for the last 15 years or so. As supply of legitimate SST manufactured EPROMS has dwindle, we had to look for a new solution and this is what we have come up with to help! Buy our SST27SF512 Eprom chip today for your tuning needs!
We are using legitimate SST PLCC chips, and converting to a board that fits a standard 28 pin socket. (PLCC to PDIP)
In addition to a normal SST Chip, we have include a 2 pin header that allows you to access either the upper or lower half of the programming of the chip so that each and every chip can have two programs stored on them simply by using the programming offset to burn a 32k program either to the first or second half of the memory. You can use a jumper or if you want to be crafty you can wire a simple switch to these two pins which will allow you to switch programs on the fly.
Everything else is essentially the same and you can rest assured you are using a genuine SST component versus the off brand stuff out there that works, maybe some of the time.
***Special Note: These do fit into a Aries ZIF socket, but you may have to carefully bend up (or desolder) the two pin header to allow clearance for the tightening handle in OBD1 Honda ECUs. If you dont need to use an Aries ZIF, you shouldn't have an issue.***
For the initial release the item will be $15 until a certain number of units are sold then it will go up to its MSRP of $19.95 each. Multi-packs will be available at a later date.
