Once you connect do NOT turn on the gauges. Click on the ROM Dump tab. The defauld ROM type, length, and current byte should be fine if you are using an 8bit 90-93 ECU. If you are using a '94 ECU you'll need to change the ROM type to OBD II (Large ROM). Save file type should be on Binary (.bin). Click the Dump ROM button. Pick a folder and give the new file it will create a name such as "Pauls ECU BIN dump". Then click OK and wait for it to finish. It may take some time but you can usually tell when it hangs as the number's will stop changing for quite some time.
