Default If a professional tuner fries your ECU...

What's the general consensus on this?

A professional tuner is logging your car when you're having issues. After making some changes, (his laptop, his cables, etc), putting the new tune on the car fails and the ECU gets locked out, requiring the car to be towed and the ECU to be sent to Cobb.

Also, they had the car sent to the dealership (who couldn't do anything with a locked ECU) who also wants an hour of labor for diagnosis before it was determined the ECU had to be sent to Cobb.

Who should pay for this?

If he made you sign waivers which they normally do, the tuner isn't really have to pay for anything. I think most tuners would eat the cost or at least split the cost with you to keep the customer happy.

as a tuner - i would buy / replace / open up and sort the ecu out without getting the customer to pay

if you are in the trade its real easy and cheap to get ecus and just swap em over - i have spares and a spare dbw ecu for when i unecutek cars - i later blank the ecutek locked out ecu on the bench and recycle it - unecutek about 2 to 3 cars a week

That's usually not the case when they blow up your car while tuning.

There is a big difference (a few grand) between nuking an engine and locking an ecu.

its really easy on the 2.5 dbw ecus

just treat them as bricked (failed flash) solder a few wires to the pc board
give it 12v and use ecuflash to load on whatever map you want - theres even a link to the documentation on how to do this from ecuflash - just enable the failed flash mode

works a treat on ecutek / cobb ecus

on the 2.0 ecu forget it - visit a breaker or ebay

I was receiving an AP pro-tune a few years ago, before I started tuning on my own, and the AP failed in the middle of its basemap flash, rendering the ECU dead. I had to get a new ECU, overnight it from Alabama to Texas, where my car was located (I drove from Oklahoma). Then a Subaru tech from 30 minutes away had to bring a Subaru Select Monitor so that we could program the ECU/immobilizer. All in all it cost me over $500 and I spent 4 days out of town, missing work, etc.

Open Source and never looked back...

^^ Pardon my ignorance, but if a similar occurrence were to rear it's head while using open-source, would you be able to save the ECU with the same software, or would you need to have a Subaru tech use the Select Monitor to re-program the ECU again?

The only tool able to program the immobilizer/keys/ecu is the Subaru Select Monitor three or later.
