Reflashing ECU (trying) - Techstream connects, CUW doesn't??

Hey guys - I'm trying to update my ECU to the latest 04B14, mainly in anticipation of ordering VFtune and the tune pack, and also to test out my "off-brand" Mini VCI cable. Got the cable working (drivers were a bitch for Win10 and 64-bit), and techstream can connect just fine. I was able to read configuration, get health status, and update some basic config items (like the turn signal blink count).

Then I go double click on my new CUW file, the wizard opens . . . and doesn't work. Says it can't get the configuration ID from my truck. Any thoughts?? All plugged in, battery tender, key in on position, just like the instructions said.

I have nothing here. Folks have struggled to get a stable connection just for customizations. There was one person that said they successfully flashed with an inexpensive cable. I can't recall his username.

All that I know is that the Tactrix is the least expensive adapter that is reliable.

Sorry!

The seller is the best resource here for driver updates or troubleshooting.

 

Don't do it..

 

Bricked ecu from a cheap cable would quickly justify the price of having bought the good one

 

Hey man, I love saving money too. The cheap communication cable could cause a incomplete ecu update. Most of the reviews I saw were this doesn't actually work along with some I felt were paid spoofs saying it did.

 

I would never ever use the cheap cable.

Even a cheap battery charger can cause a bricked ecu.

 

I use the mongoose cable... expensive. But it’s not going to drop halfway through a flash and brick the ecu... has happened at work with a worn out cable... not fun

 

Can you post a screen shot of the error?

Also, listen to everyone else here.... Don't flash TSBs with a cheap cable. The potential for disaster is too high.

If you do it, make sure you have a damn good backup plan. Depending on how if goes FUBAR, the only solution the dealer is going to give you is replace the ECM. There is a way to recover it without the dealer, but it requires a good cable, removing the ECM from the truck, some wiring, and the OVTune flashing software.

 

thanks guys for stopping me from doing something dumb - I guess sometimes you need to hear the answer you already know!

 

Where are you located?

 

Pittsburgh-ish

 

@CRCs Reality is in that area, and had offered to flash TSBs at one point. You can see if he is available to help.

 

Yep, I'm just south of Pittsburgh (West Mifflin) and willing to help

 

Thanks @lapoltba for the reference. @CRCs Reality i’ll shoot you a PM!

 

Well, I decided to just bite the bullet and buy the VFTune and the proper cable - figured I’m gonna do it eventually, so why wait!

 

Good decision man. I sure am glad about mine.

 

Definitely a good decision. While you could have held off getting VFT, using a trusted cable is the right move.

 

Well since the real eventual goal was the 2.0 SFOB tune, I’m just gonna do the whole damn thing right now
