Car Died in the Middle of Trifecta Install

[titan2782]

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.

Process of elimination. If this laptop doesn't work, it's the cable.

So I just googled Trifecta W38 and saw that it's hapenned to a few people in the last year. So far the two cars I've read were a Cadillac CTS and a sonic.

What the owner of the sonic posted is exactly what I'm going through, so HOPEFULLY it's an EZFlash issue and not a cable issue.

W38 error after Trifecta tune - Chevy Sonic Owners Forum

Here, try this one https://www.dropbox.com/s/zqffrpuzrlor7ug/EZFlash.exe it's version I use. 1.5.30.0

Make sure you're running the app in admin mode too. Right click the file and select 'Run as admin'.

Thanks Titan. I'll give that one a try. I've tried my macbook in bootcamp, my friends Lenovo laptop running Windows 7, and that didn't work either.

Trifecta W38 Error

He had the same issue as well. His was the EZFlash, and the Sonic's ended up being the laptop... so we shall see.

Okay. Further update:

Cruzester tried to help me out but so far no luck, so he put me in touch with dsj on the phone about what we could try. He's the closest dealer to me - helps he has a cruze too!

Got a dell laptop to borrow. Freshly cleaned off, Windows 7 Professional etc.

Steps:

1) Downloaded Drivers, tune & EZFlash (Vince just update EZFlash to try and fix it but to no avail)
2) Installed Drivers as administrator
3) Opened EZFlash as administrator
4) Started to 'program' (by choosing the file)
5) Plugged in the USB and waited a few minutes after the 'ding' for the driver to install
6) Hit 'OK' after the driver was installed and the cable LED went from *RED* (While installing) to *GREEN* (After install)
7) Clicked 'Stock Engine Tune'
8) Was thoroughly denied by my car, creating a frustration and sadness that can only be described as separation anxiety.

I'm still receiving the 'not found' error. I'm going to try rebooting after I eat/try different usb ports/kick my car/etc etc.

This is a complete bummer Mahoney. I really hope you can get this figured out.

Have you tried disconnecting your battery for an hour? Not sure if it's been previous mentioned, but certainly worth a shot. Give the ECM a chance to reset itself.

Did you try the EZ flash version I linked to? Did you send your tpl logs to Vince?

Yeah, tried both. It just looks like this car is SOL. Vince looked at them and said its a total fluke and this has only happened once before, but never to a cruze. Basically it's either I overnight it to Vince to fix (too late today) or I head into the dealer tomorrow to at least have the car drive able again.

Thanks so much for all the help though. If it had of been any other car I'm sure it would have been nailed on the head.

Yeah, I left it from 8-10:30 this morning. Even powercycled it to try and force it to get going.


Basically what's happened is the ECM erased, and when trying to fill it back up, it just said 'no' and quit talking as Jerry put it.

An erased ECM is an unhappy ECM.

Hmm... I hope there's not some sort of 'lockout' in the ECM if failed alterations become 'detectable'...

Mahoney, is your dealer cool about modifications? If you think they'll be cool, maybe try explaining to them what happened and maybe they can just help you out with a new ECM.
