AEM Makes a Full STAND Alone ECU for $1600 at www.3sx.com, They are an hour from me, and that's where i get all my 3000 parts, they are great guys, and have great service!

You can replace your ECU with an AEM, butyou have to decide what benefits you will have by doing this.

1) If you have a stock car and do not plan to heavily modify it,aren't familiar with tuning, and not willing to send it to a shopto tune for you: I would not advise going to an AEM.

2) If you have orare planning on light to moderate modification, I would suggest a piggy back fuel/timing controller (which would still require a working stock ECU).

My fiance and I both own 3000GT VR-4s. He runs an AEM EMS, and I use a Greddy E-Manage Ultimate. For daily street driveability, my EMU is far superior. It is easier to set up, cheaper, and simpler to tune.

If you don't NEED an AEM, just get a stock ECU. If you HAVE to have an AEM, supercarengineering.com also sells the AEM for $~1459. The owner is a great guy dedicated to bringing quality products to the 3/S community.

How bad is your board damage though? If the traces are still good, and additional components beyond the three-four tower capacitors aren't fried, you can try to repair it. I have the appropriate capacitors if you are interested.

so theres no way to fix the ECU.. coz im thinking if it only involved a single issue with one coil then maybe that alone can be addressed... ECU is quite expensive to replace
