Who rebuilds ECU's?

[Alex Bland]

Ok im guessing that my ECU is bad due to my car not starting and no CEL and i took out my ECU and 2 spots the looked like 1 drop of oil spilled on it (right next to the 2 bigish looking batterys) so..who can rebuild this thing the dealer wants 1200 for a new one

Those resistor caps get leaky, it is a common thing to happen. If you search on here, there are several vendors you can send your ECU to and have it rebuilt. I don't know the cost, but definitely less than $1200. If all else fails, you can get a used EPROM ECU on Ebay or in the classifieds here for around $150-$200.

I had my ecu rebuilt 3 years ago by (pinamotorsports) cost $210, still works great! Welcome to Pinamotorsports - Welcome to Pina Motorsports!

ECMtuning (makers of ECMlink)

Those are the two people I would most trust with my ECU.

ECMtuning do good work too!!

+1 on steve and ECMlink, both them know their stuff very well on the electronics end. You can also take your ecu to Advance Auto Parts, and get a rebuilt one for $300, this is the route I went only because I was not yet a member here, so I didn't know there were other options. I wish I would have just sent it to steve instead, from what I've heard about his work, it's better quality and the turn around is at least equal to Advance.

Exactly! Steve will pop up here soon.

I send all of my ECUs to Steve, his work is top-notch and he is a great guy.

 

[LTUDSM]

i had a deal with Jeff From Keydiver,he is also high recomended guy

 

[gstryyder]

i would go with steve or ecm link. always here good things about both! good luck with that. hope that is the only problem you are having with the car!

I can do it. But I don't have the rep that the other people do. I'm sure I charge a hell of a lot less too.

I took the night off. Thank you all for the kind words.

Alex, those battery looking things are the capacitors. The fluid inside them is the electrolyte and it's corrosive. If you don't get a CEL for 5 seconds when you turn the ignition on and you have checked the MPI and Ignition fuses on the positive battery terminal then it's very likely the capacitors have leaked and eaten something important.

How do i test the MPI relay i found the terminal gettin 12V and i dont know witch one to ground

Sorry, I though I'd answered that before.
Here's one example where I did. http://www.dsmtuners.com/forums/newbie-forum/293581-why-my-mpi-relay-not-working-right.html

Let me know what you don't understand after reading it.

at what point is the ecu garbage after the caps have leaked?

 

[steve]

at what point is the ecu garbage after the caps have leaked?

At the point where the cost of the repairs exceed the cost or replacing it. The replacement cost varies from market to market. EPROM ECUs are rare, 90's more so, so the replacement cost is usually always more than repairing it.

Two cases that I can think of make an ECU really dead, bubbled chip packages on the CPU, or port expander (EPROM only), burning though the circuit board in more than a tiny spot.

Extensive corrosion spread across the board is usually not worth repairing for a non-EPROM.

Not what you want it to look like

Image links dont work. sorry

Just wanted to post up this other option, but it's not cheap. (Bottom of page.)

So did that thread make sense to you?
