As the saying goes
"You get what you pay for"
Being the burners I use cost around $120 I doubt one costing $6 would do the complete job or at all
The Eproms GM uses in the ECM are 28 pins, the burner also has to come with software running on a P/C and
I doubt that $6 does that and the I/C socket it has allows 28 pin EPROM plugged in
I could not suggest you buy the $6 one, and then it is not working, and you're feeling I lead you into buying it
A choice I suggest looking at are example such as
( switch over to the Amazon UK website)
The burner has to support at least 28 pin EPROM, have user software and has an update function to get the newest software and firmware the burner has with the update function the burner has
One might fit your needs is the complete burner, software and also an eraser
Their software works on P/C using from MS Windows XP to version 11
