Chip Tips?!? (waterboy)

Hey waterboy, can you give me any additional info on putting the chip in? The instructions don't seem very clear to me. They want you to scrape the "conformal" coating off but without scratching the contacts. Sounds like a pretty time consuming process. Any suggestions on the best way to do this?

Also, this sounds pretty dumb, but where is the computer actually located in the car? Is it the module behind the glovebox I got the code off of?

Thanks for your help Jim

BTW--any additional info on rotating the actuator 90 deg. on the SWAB mod?

Yes, the "box" with the ECU code is what you need to take out.
1) Disconnect battery
2) Drop glovebox and remove kickpanel
3) Use 10mm (??) socket to remove large pinned connector at base of ECU.
4) Unhook ECU from black retainer strap.
5) Remove ECU from mount
6) Use 6mm (??) to take apart the ECU for better cleaning access. The cover will come apart into three parts. That is as far as you want to go.
7) Lightly and evenly remove the sticky goo covering the opposite end of the ECU where the multi pinned plug goes. You'll see 10 or so connection at the part you're supposed to clean.
8) Use nail polish between scrapings to get it all clean. When you see the solder get shiny it's time to stop. If you keep sanding you'll get to a copper color. Now it's way past time to stop and you'll need to spend time with your ECU and a soldering gun to build the connection back up. It's a bioch, trust me on this. Make sure you have cleaned both sides very well. The SCT is very touchy about getting all the goo off. 99% of all chip related problems are the result of poor cleaning.
Rebolt the ECU multipin connection. No need to remount it yet. Just leave it on the floor for now.
VERY IMPORTANT!! Make sure that before you handle your chip you touch something metal to discharge any static. Static will kill a chip in a heartbeat.
9)Slide the chip over the end you just cleaned. It should be an even and somewhat snug fit.
10) set your chip to the stock setting and hook up your battery.
Start her up. If you get - - - - on your odometer and no start, you gotta clean the contacts more. That's why I said leave the ECU on the floor for now

11) Go for a spin. I have found that when you switch from the stock program to another or from another to stock you MAY stall out. Please do not do this when driving or serious consequences may result. Any other switching of programs can be done on the fly. I just left the switch dangling from my glovebox for now.

As for the swab: No, I haven't done anything yet. I'm doing a port and valve job so my time has been elsewhere. That and I'm on call this weekend, so I didn't feel like getting too dirty and then have to run off to a customers property.

Hope this was a help.

Jim

Yup sounds good to me. I dont have any additional programs at this point, I felt it would be kinda useless with no other mods at this point.

OK well. The chip goes in tomorrow.

BTW--thanks for the tip in the static-elec. I'm a computer geek and the other two guys in the IT departemnt I work in call me "SPARKY". I think I've pretty much convinced myself that its one of those opposite nick names, since I'm the best hardware guy there.

Thanks Jim

You know when you're typing there's always something you forget. I know it should be common sense but you want to put the ECU parts back together before you reconnect the wiring harness and install the chip.
