Well, as if anything can't get any worse, my ECU died on me and all the lights went off in the middle of the road, causing me to stall and tug my car home.
:( ... This build is becoming.... has become the biggest headache ever. Any one ever run into this?.. I disconnected all four connectors on the back of the ECU, disconnected my battery and left it for about ten minutes to see if it would reset. Plug it all back in and connected the battery, still no lights. There are no shorts or anything. It was running fine before and it just suddenly died.

You've got to be eligible for some sort of prize/record man. I thought I had horrible luck when I blew my engine. Real sorry to hear man. Hope things get better for you.

Take everything out but the 8-pin plug and see if your computer can communicate with it. Ignition on, of course.

What sort of warranty comes with this ecu?

i have no clue what kind of warantee comes with it. Hopefully some form if not I'm hoping travis can shine some light in this gloomy tunnel

Oh tell me about it man Lol, First time engine blew. The rod shot out a chunk of the block with a hole the size of my fist if not bigger, second time around, my crank decided it like the rod bearing a lot and decided to bump uglies with it and give me some crazy rod knock, and currently, coolant seems to be going into the oil system and adaptronic just died

does the stock ecu still work?

I suppose I should start off by some simple trouleshooting. Check all fueses and relays. Check to see if im getting power to adaptronic from my ecu. Make sure all connectors are in. Am i able to hook up a test light to the red wire on the 8 pin connector and ground the test light to the ground next to the 8 pin connector? Is this safe?

Any way to tell? with out plugging just stock ecu in? I dont even think it will idle at all being there's 600 d'works in there and no maf?

well.. i might have found a problem. The fuse labeled engine keeps blowing its normally a 15 amp fuse.. even a 20 amp blows it. Clueless to as why.

You have a short. And yes that is the problem.

I'd plug in the stock ecu and at least see if the car cranks over and all lights come on. Go from there. I don't think its adaptronic related as much as just wiring related.
Check all the connections to/from adap AS WELL AS the little circuit board that the wiring goes through before connecting to the stock ecu.
I think I remember someone saying their circuit board had some loose connections

So that was the problem. SORRY guys false alarm,... but i had to use a 30 amp fuse when the normal is a 15 amp. Should I be worried?

SOB. that was no fun to install. and now... it has to come out :(

If you have to use a much bigger fuse that is not good. You go high enough and you'll start burning stuff. I suggest you take care of whatever is causing the short instead of just bulletproofing the fuse. They are there for a reason. That reason is so you don't die in an electrical fire.

At least now you know its wiring related and not the ecu right?

Thats a plus lol well i did find that the wire that previously went to my a/c was just hanging around there. But the a/c was never engaged. Oh well. Im just glad that the ecu is fine and its just a wiring problem. Now to start the long tedious task of tracing what the "engine" fuse wires go to :(

Hang in there man! I had what I thought was just a blown head gasket, so I replaced the gasket to find #4 was also toast. Put new bottom end in, found out on the dyno a few weeks later that this time the head didn't take properly. Now I'm about a day from completing my 3rd head gasket swap on this car! Hopefully the ARP head studs ensure the thing is bolted down properly this time!

Cars have ups and downs like rollercoasters. Just think of the stupid grin on your face when you get it sorted.
