Help! Ktuner fail

Please help guys!

I uplodupl a new tune today and when I went to turn off I forgot to hold down the power. Now it's not turning on at all.

When ktuner is connected to computer it says connected, but when I plug in OBD2 it won't connect!

Please help me!

Isn't it supposed to go into a "recovery" mode where you can upload the factory tune?

From an earlier thread...

"Turn everything off, unplug everything, and then re-connect / reboot. It should recognize that it's in recovery mode and prompt you for a flash back to stock. You can then re-attempt the flash at your convenience."

Yeah I read that, so i unplugged everything. and when plugging everything back in again it wont register... Do i need to let it just sit and try to connect for ages?

Literally have tried everything that I can find on these forums. Emailed off to ktuner but they're closed. I have the ECU comm failed screen pop up with "Retry" "disconnect" or "recover ECU" but the ECU on is greyed out! how do i get that one to ungrey itself? @KTuner Please help

And give us an update please .

You can check the LED status to see what the unit is doing. If your battery is low or dead that may be the cause.

Hey all, I ended up fixing the issue. It appeared that my battery went flat which I found to be really strange considering the battery is not that old.
@KTuner instructions are clear and I was following it, the upload was just failing twice due to the battery not having enough juice.

Any suggestions on how to not drain the battery so fast? It dropped to like 5.3v??

buy a battery tender. Outside of that, dont put the car in on position until you are ready to flash. get your tune loaded first, then go to the car. Makes sure the ac/heater is "off" it will draw a lot of load without the car started. Also turn the headlights off of auto if in the garage and they come on.

These batteries are pretty bad. A battery tender will be very handy if you flash often.

Appreciate the info guys! Cars running happy now

Happy to hear it! That's the goal!

The stock battery is junk. pretty sure a motorcycle battery would be an improvement
