Does it make a click when you try to start it? Also you checked fuses incase it is something stupid like a starter fuse?

EDIT: And the car won't start. Also, the OFT does not turn on when I turn the key to ACC

I think you battery has died, check battery

will headlights turn on ? are they full brightness

Check the pins on the cable going into the OBDII connector carefully. I've seen other posts where the pins got pushed in a bit and were not making contact.

I road tripped down to North Carolina. Now I can't leave!

I attempted to contact Open Flash via email. They have not yet responded.

I'm in a full blown panic.

Suspect battry in car has failed, dont flash cars with weak or dying batterys as it can fail mid flash. ecu needs stable volts to flash correctly

Alright since there must not be an immediate and obvious answer I will give you more information.

I bought it 2nd hand from a fellow forum user. It was unmarried when he mailed it to me. I married it to the car. Flashed Stage 1 successfully. Enjoyed it. Flashed the e85 tune successfully. Enjoyed it. Flashed back and forth a few more times. Successfully. Finally, I flashed it back to stock and took it to the dealer for an oil change.

A few weeks later I pull up to the e85 pumps and attempt to flash to e85. Got an error message that said "An error occurred while communicating with the ECU. Please try again."

Tried a bunch of times. It didn't work. Emailed the guys at Open Flash. They responded, then my life got busy. Threw it in the glovebox and forgot about it.

I went on this road trip. Visiting a car buddy for the holiday weekend. Figured I would try it. I assumed worst case scenario was it would not work again. I assumed catastrophic failure would not happen. This may have been my mistake.

It makes no noises. Checked fuses, they look fine Do you know which ones specifically?

Headlights seem fine.

Tried with a second OBDII cable. No problems. Went to Autozone a few weeks ago because of a CEL. Had no problems.

There isn't anything wrong with the battery.

[go_a_way1]

I don't I haven't look to much into the fuses. Im out of ideas, hopefully someone can think of something you haven't tried yet.

Experienced prior that Error occurred while communicating .. ?
Hmm, my bet is on bad contact/cable. Could it somehow fail in mid of flashing?

Ok after this info its looking bad.

I think the oft or the connection to oft or the battery volts is to low for flashing to complete.

One on those senarios has resulted in a partial or failed flash. During The reflashing process the ecu is first erased then the new rom is flashed.

I think your rom is erased or only partially flashed this will result in car not even cranking

If you have any other car arround with an obd port plug oft into that and see if it powers up this will check oft and cable.

If that works check the your cars obd poert pins and the fuse for obd port.

That's exactly what I think happened.

I think it was a partial or failed flash problem.

Now, just so I understand, when I plug the OFT into another car. Should it immediately power on, or do I have to key to ACC? Or even Key to ON?

It should immediately power on, I've had this happen to me but I just unplugged the oft and plugged it back in after 20sec, I should also add I've never tried flashing the ecu anywhere but home since I use an on board charger just in case something like this happens.

Lesson learned. Flashing away from home is dangerous.

So if the keys are out of it and I plug it in the OFT should power on?

Depending on vehicle oft may imediatly ppwer up of it may require key to acc or on position. some vehicles switch power to obd poert with ignition some dont.

Not trying to be a d1ck but with your own car make sure your switching ignition to full on position (do not try to start) when you flash ACC position will not allow flash process.

OFT should power up on a brz\86 straight away on plug in though

I don't think you're being a **** at all. I'll take whatever help I can get we are checking fuses with digital multimeter now.

There are only two fuseboxes right? Driver side and hood.
