With the programmer plugged into a USB port on the computer, open the Flash N burn software.

All the pins should be in the bottom side of the plug which is opposite of what you would think. Then place the H1 into the Burn2 programmer. All the pins should be on the end where the big brown chip is which is why I have the blue cover off that factory memcal so you can see which end the H1 header needs to be in. Start by putting the needed H1 header adapter from into bottom of the GM memcal.

Now that it is installed, in this illustration, we are going to read a 27C256 eprom chip from a 16147060 computer from a 1991 454 4L80E truck. Nothing too crazy about the installation of the software so I am not going to that detail. I prefer to use the Flash n Burn software that you can download from the websiet when you order your Burn2 programmer. Doesn’t work so well with the old systems that use the 2732 24pin eproms but for TPI that uses a 27C128 or 27C256 depending on year system or the 91-93 TBI 4L80E trucks that use a 27C256 eprom or the 1993-1995 4L60E and some 5spd trucks that use a 27C512 eprom chip we can piggy back off those with a GP1 adapter with some 27SF512 eeprom flashable chips. Its the cheapest alternative I have found to programming your own chips. so just what is a flash and burn programmer. I am not patient and don’t expect you to be either. saves a LOT of time by email these files rather than waiting for chip to arrive through the mail. Customers with really complicated setups that we know is going to take several chip adjustments to run correctly often prefer to burn their own prom and I can just email the files to burn to the chips. I am creating this page for those customers that decide to use a flash and burn programmer.
