well, i've spent about 4 hrs total and got almost nothing done. i put together my converter so i can plug in my laptop to the ecu. I got all that hooked up and i was trying to unsolder my chip, but no luck there. so i stopped and put everything back together. wanted to see if ECU Control would work. well then i found out that you need to chip the ecu for ECU Control to receive any data. And also i dont think my ZIF socket will fit onto my circuit board. So...it's been an almost worthless day. Any ideas about the ZIF socket? The chip has a cap and something else too close to it and im pretty damn sure than socket wont work. But, i'll probably be off to the store to get a solder sucker...since i had no luck with the wick. what a shitty day.

what ecu.. also i dont suggest sscrewing around with your own ecu get a spare.

Yeah, I got a spare one to mess around with because it would be my luck I short something out and have no other way to get around!!! But so far good luck.

well, now i've gotten a solder sucker and sucked all the solder out and it still wont come out.

is the chip glued down at all, its sitting extreemly close to the circuit board...in comparison with the other chips.

Use the wick and Radio Slack desoldering rion with the built in sucker bulb in tandem.

Put the wick over the pin you need to desolder, press the desoldering iron down so that the pin pokes (thru the wick) into the hole in the desoldering iron, hold heat there for ~5 seconds and suck. Lift the iron and wick off before you are entirely finished sucking, or else you get a little flow-back.

As the board starts warming up from desoldering, and as the wick gets more saturated in solder, you don't have to heat the joints as long.

Before you go to pull the chip, take some really delicate needle nose pliers and wiggle each pin to make sure it's desoldered. It either wiggles or clicks free + then wiggles. Otherwise you end up tearing free a pad/trace which is

The transistor that you think is in your way can be gently bent to the side and about 90 degrees... your socket will fit, just be very gentle.

As far as the "glue" that holds the socket down, be careful. There are a few traces towards the top of the chip that will lift if you just go pulling it out. I've found that if you start at the bottom of the chip, and slip a small flat head screwdriver under the chip, and SLOWLY start to pry it up, that it'll break the seal loose and let you wiggle the chip out.

The "bottom" of the chip points AWAY from the ECU harness connectors.

When working on electronics, make sure that you are grounded. If not, the electro static discharge that your body can give off can easily burn or short IC's internally. So just as a precautionary..

Instead of a solder sucker, get solder wick... workds much better..

Sucker + wick = better than either alone.

i like to suck and clean my wick
