I wanted to stess the importance of replacing the capacitor in the ECU. The capacitors used are electrolytic capacitors which means they are acid based over a period of time and heat cycles they will expand to the point where they will become porous and will leak acid on the board. Know symptoms of this is random stalling, a fish like smell, injector(s) not working. I know there is more, maybe Jeff will be nice and chime in.

REPLACE YOUR CAPACITORS! or else you will be mad.

I've got a DSM ECU you can borrow while you send yours off to be fixed.

Bad capacitors can also cause the infamous and dreaded code 44. So change those caps, it is easier than you think.

Also, make sure that that any leakage is removed. Otherwise, you may have the same problems.

Keydiver is no longer taking in repairs/socketing/caps replacements, sorry. I highly recommend you contact russya on this group, or Dave Mertz of DSMLink in Virginia.

IC105 and IC107 are just ISC drivers, they won't kill the ECU.

How about some specs on the Caps?

I agree that its very important, lets just give a little more info to the newbs if possible.

I always like to tackle a job with replacement parts already in hand.

PS Jeff is the man!

I just did an ECU that looked perfect. I removed the caps and one of them had ate through the top of the board Killing 2 runs. Took me an hour more to fix.

Just because they look good, DO NOT TRUST IT.

Please do it NOW!

I used the vFaq for clear instructions and ordered the caps from Digikey. Less than $10 with shipping and handling.

you can get the caps for $5 shipped on ebay.

If you need any ecu service done, contact Terry Posten on the board (that's his name and handle). He offers socketing, recapping, and board repairs.

Dead links in this post, perhaps we could have a running update of who offers cap replacement services and ballpark costs, as well as a new link to the DIY page, I have no idea where to find the info, but jsut a suggestion.

Yes, but they most likely have never seen one of these before and may not be able to find all the little places that go bad when acid leaks. And they may not have the correct spec caps and might try and make it work with parts that are not correct of up to par for the environment the ECU sees.
