i flashed a custom tune on my ecu.my car wouldnt start so i tried to install my factory tune and thats when my ecuflash is reading"no response to anyknown code" ..please help

 

can you read the rom from your? can you reflash to your car at all (meaning any rom)?

 

nope

 

i am not familiar with the ecuflash logs, however, make sure your battery is giving the full charge (12V) and both wires of the cable is plugged in

 

I'm encountering the same problem. after i uploaded a new map.

I've had such encounters before but usually upload fine again after a while. this time i cant read, or upload anything to the ecu. But evoscan works fine... Any ideas?

 

all that has been checked and still wont read

 

Sounds like a battery problem to me if you can't even read your ROM. Did you copy over your immoblilizer code? Maybe your ECU has been locked.
