Dealer replaced ECU, now OFT won't work, any ideas??
 

I brought my car into the dealership for the valve spring recall. Two weeks later, the slip angle light, traction control light and check engine light came on and the car is really slow. I take the car back, and they state, it's an unrelated problem that the cam sprockets are bad and they damaged the ECU. Ok fine, so $2600 later, I get the car back, running well. I wanted to put back in my tune but obviously the Open Flash Tablet won't work now because it's married to the old ECU. What can I do? Any ideas??

Thanks for any insight/help

You can t do anything, you should have put the stock map before so to unmarry oft
Now it s kinda bricked
Maybe you can contact OFT and ask rhem if they can reset it if you send it to them
But you can t do anything to make it work, unless you ask them the old ecu and see if you can install it back and unmarry the oft

I'm not sure, but I think @steve99 said that the dealer needs to put the old vin in the ECU and that the OFT should work.
As far as I know the OFT is linked to the VIN number.

one of 2 things happened... same happened to me..
1. orgininal ecu had your vin# written to it, new ecu does has blank vin#. Solution, use Tech Stream to write vin# to new ECU, then your OFT will work.
2. Old ecu didn't have vin# written, but new ecu does. In this case you'd best be on the lookout for someone with the same year / model, ecu that does not have vin# written to it, flash stock tune to other ecu, unmarry OFT, then re-marry to "your" new esc.


#2 happened to me. Nothing you can do short of sending it (oft) back to OpenFlash for replacement credit, and order a new one. Or just buy Tactrix and use OFT for real time guages.

Check the VIN number on new ecu matches whats storred in oft. Id say dealer forgot to set vin number in new ecu or they typed it in wrong

That sounds like you need to talk to toyota or subaru head office. Tjey worked on those can sprokets and if thats what causes issue then you shouldnt be paying

Thanks guys, I did flash the ECU back to stock before this whole thing started. I emailed Open Flash, and they said "

You'll need to flash the ORIGNAL file, back to the ORIGINAL ECU (after re-installing it).

Then, erase your OFT, install your new ECU again, and install the OFT onto the car once again."

I'm going to try erasing the OFT as they suggested, then try and see. If not then I'll try the Tactrix.

I did contact Toyota Corporate, and they supposedly will reimburse me $750 but I had to pay the whole thing first.


Still it should never have even happened....
