OFT won't respond
 

2014 FRS. I just went back to my original OEM catted header and planned to flash my OFT accordingly. I'm running a Phantom Electric Supercharger with 93 octane and the current tune is for stage 2, which is for catless. I plugged my OFT into my computer and started the manager just to see what I had, and it went through a great many updates, then asked me to approve a new software version. I was concerned at that point because it's been three or four years and I didn't know if the new software would recognize the codes that are on my OFT, so I declined.

I plugged the OFT into the car, but when it tells me to turn on the ignition and press OK for the tune, It won't respond. I tried a stylus and that didn't work either. I can't get to the tunes that are on my OFT. Maybe I don't have any choice but to install the new software on the OFT and hope it will work then. It's pretty worrisome. I don't want to end up with a brick

Can anyone advise?

29 visits and no response. That's not very encouraging. I think I'm dealing with a bad OFT. I recall when I put the last tune in it seized up two or three times and the only way I could get it going again was unplug and plug it back in. So I think if I buy a new OFT and download that file which is available from OFT and which I have in my file manager anyway, I can probably install the proper tune.

Running a tune for catless into a catted header means a rich mixture which might damage the current header, so I better get to it.

There's an Ecutek guy here in town. I talked to him and he said they can sometimes fix it but it has a possibility of bricking the ECU as well.

If you have Facebook there is an open flash tablet FRS/BRZ tuning and support group. You'd probably have more luck on there given forums have slowed down a lot after it bugged out for several months.

Thanks, really appreciated.

It's been like 10 years since i had my oft, but I remember everything had to be perfect. Done light off, door closed, fully charged good battery, etc. I'm sure you know this ,just making sure.

Fixed it!
 

I'm running an ESC, so my starter battery is for a motorcycle. I got to thinking that battery might be a little weary at this point anyway, so I charged it overnight and left it on charge. The tune went through without a hitch.
