$42 soldering for a 27SF512 socket

[WallyCJ7]

Thanks guys I may take you up on your offer. I find that one pin may not be soldering for some reason - probably dirty. I thought I cleaned everything really good. Now I need to find out how to clean it enough to get it soldered without pulling the whole socket.

Sturgillbd I may take you up on your offer if this doesn't work.

The more I fight with this thing the more I'm thinking about switching to a 16197427 just for the security of being able to getting one that doesn't need modification. Since I have a junk 7747 I could make a pigtail to my harness allowing me to keep the (once I get working) 7747 as an emergency ECU.

I like that plan! http://www.gearhead-efi.com/Fuel-Inj...out-Directions!

You can get solder flux in a pen, paste or brush on format to help with cleaning contacts. I prefer pen or brush on format for re-work/repair/modification.

No, I'm not in the US.

Flux will definitely help soldering the socket into the double-sided board. Here is what I use at home for desoldering through-hole chips. It works great but has become quite expensive since I bought mine. http://www.mcmelectronics.com/produc...FYRFaQodYqQAvA It was $139 when I bought it several years ago.
As for going to a 16197427, that is what I used on my Willys Jeep. I have tuned a 7747 and an 8746 based transplant. It doesn't take as long to get data points at different loads and rpm etc. It just has a lot more tables etc in the bin file. You really need to use a VSS with the 7427 also.
