Well I cleaned it and scratched off some on the tin, like 3 streaks from were I used my finger nail, But plugged it in the truck and the truck still starts, So any harm done to it you think? It looks pretty clean though

 

If that is with chip installed you should be ok. But if you haven't installed chip yet you won't no until then.

 

Yea haven't got the chip in the mail yet. So what can I do if it don't work? Spose to be here today or tomorrow around 2 pm.

 

If the chip fits tightly you shouldn't have a problem. Also be sure to tighten the PCM connector bolt after installing or you might have a no start. The bolt needs to be tight to ensure all the pins make good contact.

 

Will do, Ill post as soon as I get it installed in and try it. Thanks

 

I got my chip in yesterday! I'll be cleaning my PCM and installing it on Sunday but wont be running it untill I get the injectors next week.

What did you do that scratched it?

 

Used my finger nail to clean it off. After I realized it scratched I used acetone to clean it and it don't really look that bad. Like the guy said as long as it fits snug it should be ok I hope

 

Joe,
I used a brass bristle brush (sorta like a tooth brush) and it worked excellent. You can find them at your hardware store or even Harbor Freight Tools. The brass removes the silicone but doesn't really attack the tin too much so you might want to give that a try first. Here is the general procedure that I used...

I put on a dark T-shirt (dark red, black etc).
Then I removed the PCM per usual instructions and then opened it up to expose the circuit board. While holding the circuit board in the palm of my hand (with my elbow tucked to my ribs)...I brushed the silicone off the contacts with the brass brush (brushing towards my chest). If you are wearing a dark shirt, you will see the tiny bits of silicone collect on the shirt. It will only take 6-10 brushes and you will notice that no more silicone is landing on your shirt.
Turn the board over and do the other side the same way.

Now, look in between the contacts and use a toothpick to remove any remaining silicone that is BETWEEN the contacts.

At this point the contacts might still appear somewhat shiny or glossy. Use the scotchbrite pad to lightly buff the contacts until the tin appears dull (or a matte finish). Stop when you knock off the glossy finish because that means all the silicone is gone.

At this point your chip should fit snugly and make positive contact.

This seemed to work great for my truck so hopefully it will help you out as well.

 

and tape the bejesus out of it once you get it connected. Don't want the connector to move.

 

Well got my chip in today Just got done testing driving it. I'm very impressed with it from going to it from a edge programmer. Had a problem the first time, connectors wasn't clean enough so cleaned it again and used the pad it came with worked real well.
