Resolved EPROM questions.

[jorge4g63]

Hey peeps,i have 2 questions regarding eprom ecu's. I tried searching but found nothing regarding my specific questions.

My questions are:
1.How do i know my ecu is eprom, mine is fried and i bought another one, they both have weird numbers on them.

2.What does "socket" or "socketing" the ecu mean, and what is it done for?

Also the ecu i bought came off a 1991 awd tsi, i installed it and it works mine is fwd, don't really know if there is a difference.

Thanks in advance, any help is greatly appreaciated.

That should let you check out the ECU to decipher if it's an eprom.

"Socket" In this case, is a socket pin, that is soldered in your eprom chips place, and then your chip can be placed inside of it. The advantage is the ability to change to a different chip/tune it, etc, without havening to hard solder the chip itself to the board.

That was just the answer i was looking for. I'll check it today.

And also, can anybody answer if the awd and fwd ecu's are different?

Thanks again blackbyrd.

Oh yes, didnt see that. The FWD have a speed limit governor on them. The AWD don't. Thats the only difference.
