ok how do i do it? i have removed that part of the cover, and i am starting to clean off the ends of the circut board with q tips and nail polish remover. than i took a razor blade and carefully scraped the gel off, not going past the point where the copper end parts turn skinny.

do i do this to the other side too or just leave it the way it is? any thing else?? am i doing this right?

Yes, both sides get cleaned the same way. Keep repeating your procedure if once you get a signal through to your laptop, some values look crazy.

Yes, both sides.

I have used "aircraft paint remover" (spray can) with great results on two ECMs. With that and a razor blade, I can do an ECM in less than 30 minutes.

Can I ask you guys what the hell you're talking about? How does the Direct Scan work and why do you have to cut up the ECU?

87natty,

In order to use Directscan, you need to remove a a portion of the ECM cover to gain access to the circuit board edge connector inside. Then you will need to remove the protective plastic-like coating on the edge connector so that the Directscan ribbon cable can read the ECM data.

The question was regarding cleaning the protective coating off of the edge connector.

Sweet, is it like a plug in, do you have to splice it in? Just curious. Hey, this might be my 100th post! Holy hell, I'm halfway to an avatar! I'll use my real life mug shot! :)

It is usually plug and play, after you get the connector cleaned up. The DirectScan connector goes in between the feed cable to the ECM and the ECM board, and reads the signals directly. It feeds this info to your laptop, like TurboLink. This gives it much more frequent data sampling than other scan tools, which rely on the sequence of data which is sent to the ALDL. (Go the the Turbolink site, and read a more detailed comparison) It is not always compatible with all chips, and sometimes the connection gives problems.
