I was driving into work this morning when all of a sudden the car just died. No sputtering or nothing. Got it towed to Ford Dealer and they hooked it up to the computer. There getting no reading and telling me that the computer and diablo are fried. They said it must of shorted out.

 

dang man that sucks, well...time for a F.A.S.T bank to bank and a good check on all computer grounds

 

Let us know if was tuner related!

Sorry for the car letting go...

Now time for a new one

 

I have to get a new chip (tuner). Whats a good 1. Gonna probably get the ecu from a junkyard.

 

Do you still have your OEM chip?
If so, try putting that back in and see what happens before going for a new ECU

(The way I read your message you have a physical chip, not a tune from an outboard tuner)..

HTH

Yes Custom chip. Now if i get a new ecu what should i do. This is the second time i'm having a problem. 1st time i had a melt down. Just get a hand held tuner or what. I'm lost with this.

 

I would NOT put that custom chip back in the new ECU....

Generally, ECU's don't just *fry* for no reason.

Assuming a stock ECU, the most common cause for catastrophic failure is a short on input side to the computer which is where the sensors connect to and which generally has 12 v on it and the potential for that 12V to short to ground via a chaffed wire etc.

There are no fuses inside the ECU because the output transistors that drive these circuits ARE the fuses and once they blow that's it...New ECU time..

Compared to the ECU *losing it's brains*, the above is much more common.

However, when you throw a another chip into the mix, now you are adding another possibility and it could be that the chip
went bad (not programming wise, but electrically) and is taking the ECU with it.

I would put the original factory chip in the new ECU but before hooking it all up, look at every sensor you can locate and check the wiring for frayed wires, shorts to ground and stuff like that.
Check any place cables lay around metal because vibration can cause the insulation to wear over time and short out.

Also sniff the old ECU and see if it smells burned.
If so, do NOT put the new one in until you can at least hunt around for the short.
Burned smells are a sure sign of a short.

 

Just get a diablosport predator and be done with it.
