I have tried to start the car (brand new battery), cable is plugged in correctly, and key in the ON position. Doesn't work, keep getting the "no response to any known code". I have tried using EcuFlash and Evoscan. I can LOG with evoscan but can't flash the new ROM in? Can anyone help? Thanks

 

try it with the car running..

see if she stals when trying to read the rom

 

already tried that too, same result

 

yes but does the car stall?

 

no nothing happens, idles as usual

 

then the fault is in the smal flash connector..

you got the 2 plug'd into the car?

the engine must stal when you try to read or flash in a rom

 

I had the same problem last night, it was the low battery. Also like others have said, make sure the second connection is plugged in and make sure that wire is not loose. My wire pulled out during my first tuning session and I wrapped some electrical tape around it to make it more snug in the plastic

 

thats why he should test with the engine running

always 13volt +

 

Yes I have the small white single wire connector plugged in as well

 

Is there a tuned file in the ecu already?

 

If the car dont stal it is that connector.

Try to jiggel it about

 

I have used this cable/laptop several times to flash my car before. BROKE4 yes it does, but I don't think its locked, if that's what your thinking. I tried wiggling it. Is there anyway I can test it with a volt meter?

 

Yes..

Should be 12v on the there when you try to read

You can try the unlocker to

 

Im only getting 4.65 volts to the small single connector?

 

I think it must be 12v.
What car and OP you got?
