Default Probs with the unichip, look at the pics

I was just driving my car and all of a sudden it cuts out. The car wont start but it runs perfect on the stock ECU. Car wont kick over with the unichip and I call Mark @TXS and he said all the ignition drivers are in the chip not the harness. Though I see something on the harness that obviously looks like a problem and I am wondering if this would cause the issuse of not starting/running. Pics


It looks like something blew out/burnt out. I dont know, anyone know how to fix this? Thanks.

I am sorry but I think you may be SOL... you may have to replace it all together!

I don't see how that could be fixed for less than the cost of a new one.

The real question is is what caused the board burn out???
If there was a real falure in a component then a jumper isn't goin to fix it.
If there is a chance it was a bad spot on the board some one good with a soldering iron can fix it. I'm not going to recomend puting a peice from point to point on the board, but just a local fix so if there is still a real problem it would burn its self clear again around the fix. If you know some one it might be worth a shot.

looks like a blown trace, no biggie. if you can, trace down both end of the trace and just solder in a jumper

Circuit boards can be repaired, I've done it many times. The question is what caused this to happen- board traces don't burn out like that unless there is a component or wiring problem that results in excessive current being drawn through the trace.

edit- looks like I said basically the same thing as GL, I was typing this just as he posted.

i honestly dont know what happened... I have had the chip in my car for a little over a year. I was backing out of my driveway and my car just died. It wouldnt kick over so I took out the chip and its been running fine on the stock ECU. I have no clue what happened and havent done anything different to the car within the last 2 months. It was running perfectly up until this point then all of a sudden I spot this problem.

Anyone have some good instructions on how to fix this? I guess I got nothing to lose since its shot anyhow

There is two ways to fix it...
like mentioned, follow the "trace" untill you find the little silver dots... find a fine peice of insulated wire (18awg), strip about a 1/16" off each end & tin the wire. (Tinning is preping the end with solder so it is already saturated with solder so it doesn't wick the solder out of the joint.)
Basically you need to connect point A to point B.
Apply heat only as long as needed so there isn't any damage to the peices on the board.

The other option is it scrape a little of the resin coating that is on either side of the break untill you see bare copper. (an exacto blade works wonders). Add a touch of flux, & a little glob of solder or a short peice of tinned wire over the area... The thickness of the solder had ampacity is well in excess of of what the board can handle. If it fails the solder joint will survive & the trace will burn again.

Hopefully it was a scratch or flaw & it works... other wise you may get a poof of smoke... If it will take any thing else out when it goes, duno....

Looks like the trace is scrap off instead of blown... Are you sure theres nothing comes contact with that trace? Maybe you should make sure theres nothing 'hitting' that board.
