Hey all,

I've submitted a ticket but until I get a response I thought I'd ask around.

My car was 95% of the way through installing trifecta and all of a sudden it came up saying there was an error loading the flash and to try again in low speed mode. I have tried since then but no luck. My car will no longer start, and no matter what I have tried I keep getting a 'cannot connect to car' even though it is in fact in the on position.

So currently, I cannot connect to the car, in on it says to service traction control, and the starter won't well... Start.

Halp plz.

EDIT: I've included screenshots of the error message for reference. Text Font Screenshot Games Computer icon

This is no problem. Here is what you do, reflash the stock tune. In the menu there is an option for low speed. Enable low speed then reflash stock tune. This will take about 20 minutes.

Make sure it all works and then try to flash the perf tune again.

Make sure you have the key turned only one click. If your gauges are turned on then you've turned it too far and will receive error messages on the DIC.

If the car "won't connect" then turn the car off. Unplug your cable from the laptop and close EZ Flash. Make sure you have latest version of EZ Flash. Connect the cable to the OBD2 port and then turn your ignotion key one click.

Reset your laptop. When windows comes back, insert the cable into a DIFFERENT usb port and wait for the sound to indicate it was connected. It may need to install drivers again so just give it a second. Then start EZFlash. Go into the menus and use the Code Scanner so check for codes. This is only to make sure you have a connection.

Once you do, follow my previous instructions on the flash.

Make sure you turn off A/C, Fans, Stero, etc in the car. Make sure doors are closed.

And if that doesn't work, do a force full flash on the stock tune and you should be ok. I only recommend you don't do this first because I have no done it and NO ONE has yet to tell me what it actually does. My concern is the flash count.

Just don't let the laptop go to sleep. Move the mouse every 1 minute or so. Make sure it's plugged in too. I let my laptop turn the screen off and it killed my car. So scary when it happens the first time!

Thank you so much, Titan! Unfortunately I had to go in to work, and no one could cover (sucks being a supervisor sometime), but when I get home tonight I'm definitely going to start and give it a retry - and I'm hoping you nailed it on the head.

I really appreciate the quick response! A terrifying experience for sure.

Fingers are crossed.

I'm really glad I'm not the only person who this has happened too. Luckily I was able to get tomorrow evening off from work so now I can spend some time trying to get it straightened out! Again, thanks Titan, not only were you quick to respond, but it was quite a detailed response at that.

My laptop turned off during a tune so I already know how to fix it :) Let us know what happens.

Alright guys. No luck. No matter what I've tried, it does NOT want to connect. Keep getting the same 'can not connect' error.

Pull the battery cables and power cycle the car. i.e. pull the positive cable, then try to start the car for 20 seconds. hook up the batt cable again and give it a whirl.

Try a different laptop. Try different USB ports. Try turning the car on (running) and then attempt a data log (I have to do it this way to get data logger to work). If that works, turn the car off using 1 single click and then try flashing again (stock).

What version of EZ Flash are you using and what year is your car? Do you have push start?

Left the battery unhooked for 2 hours, power cycle (assumed I did it correctly as my keys were stuck in the ignition) and put it back in, tried doing bootcamp instead of parallels.

Light on the trifecta cable is a yellowy greeny, so I know it's connecting fine on the computer end.

I just keep getting this 'can't connect to car' Error. No matter which position my key is in, or what order I plug the cable in vs when I plug the key in.

But I am using the latest version (10.5.45 I believe), and the Car is a 2012 LS AT, so no push button!

No, do not use Parallels! Parallels is still a VM. Just borrow someone's win7 laptop or drag your desktop out there. If that doesn't work then I suggest you have a bad cable. Ask them to send you another one immediately and then you'll return your broken one.

The cable light will be on because it has power from USB but it doesn't mean it's connected and correctly operating.

Additionally, did you let Windows install the drivers or did you download them yourself?

Well I've also used bootcamp so I do not believe it to be a VM issue. I've got a friend coming over with his laptop later so we can give that a shot. The only computers I own are macs sadly, last PC I bought was in 2005.. And I sold that a few years ago.

The cable is red when I first plug it in, yellow when I open trifecta, and green/yellow in the OBDII port, which I can imagine it means its working properly.

Downloaded and installed as per instructions but I bet it wouldn't hurt to uninstall and reinstall, but I can't tell which thing it is in the device manager

Just plug it in to your friend's laptop (make sure he's online) and let window do the install. That's what I did (by mistake). Uninstalling the drivers doesn't really uninstall them. If that still doesn't work, then try to install the drivers like you did previously and try again.

If you friend's laptop doesn't work, you need a new cable. If a new cable doesn't work then I guess you will have to bite the bullet and take it in. Just play dumb!

Before you take it in though, call Trifecta and get help from them.

Have you tried the force full flash yet? It may work even if it says it isn't connected.

Hopefully it's just the laptop (even though bootcamp should be the same as a PC, it apparently is not).

I've eliminated that it's my OBDII port at least (I have the window fob controller), and that still worked when I plugged it back in. So I know the OBDII port and the connection is fine. It's just a matter of the laptop and the cable working. I still think the cable is fine, but we shall see when it gets in the actual PC laptop.

I tried the force full flash and it just gave me the same connection error and then closed.

But yeah, I really hope I don't have to take it in to the dealer! I mean my dealership is cool...but I've also never screwed up the car myself haha.
