ooh sorry bout that projekteg, i feel embarrased :-[. didnt realize that u offered ecu chipping service too, i wouldn't have said that if i knew. yeah i can see why that could be taken badly, tellin u that if u can't fix it i'm taking it to your competitor. not cool of me. well now that i know better, yeah i'm gonna try to find me a p06 to drive on, i doubt i'll be able to though and don't wanna buy a new one unless mine is fried. i really can't spend too much money right now, i just got in a wreck so i gotta get a whole new front end for my car. its drivable, but i really dont wanna drive around on it long, looks like ----. i'll pm u about that right now.

if the ecu runs with the jumper cut, it's not fried, just a problem somewhere with the soldering more than likely, usually pretty easy to fix. when people send me fucked up ecu's, i just desolder everything and clean them up, then solder in all new components (i don't replace the zif, theres no real way you can ---- that up, but i do desolder/resolder it to make sure the joints are good). i've repaired a lot more fucked up ---- than yours ;) if you can find another ecu, you can send me yours and i'll look at it, try one of my burns to see if it was just a bad burn, and then go from there.

Armed with a soldering iron, solder and a volt/ohm meter, fixing them takes just poking around. You can usually tell with experience where the problem is as soon as you open them up.

i just got my bud from GA Tech to desolder everything and re-solder it, which was a PITA, and we're still getting the exact same symptoms. :-\ which means by process of elimination, it's either the 74HC373 chip or the AT29C256 chip.

i don't have much experience :P half the time all the soldering looks like ----, and i'm the type of person that likes things to look neat if i'm even gonna claim any part of, and it takes like 10 minutes to desoler and solder back in a couple capacitor's, resistor, and latch.

by experience I mean, you could tell that there is a lifted trace on the board and someone else can't. Some people have a hell of a time trying to desolder the 28-pin dip. What a pain in the ass. and end up lifting like 5 traces in the process.

my friend's in the engineering program at GA Tech, i don't know anybody who knows more about what they're talking about than he does. he said all his soldering was done right, and i trust him over anybody else's opinion in a situation like this. he also has a civic, part of the reason he agreed to do it was because he wanted to see what kinda results u could get out of uberdata... now if we could just get it working...

Did you try a different chip? Or another 20 pin latch?

if you send me the chip, i'll try it out in my car before i even touch it, that way, if there was a problem with it in my car too, then we would know for sure it was the chip. honestly, that soldering didn't look too good in my opinion, way too much solder on the joints, which means he had to hold the heat on the objects longer, which means more of a chance to fry something :-\

Re:uberdata problem- bogging and cel
 
yeah, that was my work, i figured it'd be better to use more solder and have better connections... his job looks way better than mine... but if I fried it when i did it, then it still wouldn't work after he did it.
