What did you get ?
Unless you are doing it the old fashioned ( and very slow ) way of erasing the stock chip , you use an adapter in the ECM to mount a reprogrammable chip.
Remove chip from adapter , install in your burner, load new program , reinstall in adapter , drive car.
Is your chip from Alvin in an adapter like this?

In which case you carefully remove the chip to install in your burner for programming .You would download and save the tune that is on it first as a back up reference.
If you write a new tune on chip whatever is there is lost

Don't know what style Hypercrap use but Transonic unit and eraser will only work on the old style EPROM chips.
The SST chip (EEPROM ) needs one of these to reprogram , much faster

A simple as loading a file on a floppy disk ; put chip in burner , delete file , load new file , done
Some reading; Section 5
