I had to try various combinations of plugging/unplugging the cable, turn the ignition on/off, etc... I did find that if you had the flash switch towards the TXS symbol, it wouldn't see the cable in the Hyperterminal, but it would still see it in the reflash program.

Really weird, but I finally got it to work

 

thanks ill try it all again tonight.. i already ripped it out ready to send it to TXS but ill try tonight. hey who did your tuning in Colorado? I might be driving up there if i can get this fixed so i can get tuned

 

MAC Autosport in Parker, CO. Just SE of Denver. Website is here

 

Im really surprised the USB isnt working. I actually just pulled the USB cable off of my printer and plugged it in to the UTEC. With the USB cable you should be able to at least determine which COM port you are using. The COM port will never change for that USB port on your computer, unless you change the settings or something. I know you are probably sick of the UTEC, but I would check and make sure the switches are in the correct positions again. And you might try calling TXS directly before sending it in. I have heard that if you can get a hold of someone they are very helpful and will spend time on the phone walking you through the steps. And If the UTEC is out of the car remember the 9V wont last very long once the processor is running.

 

sounds like a wall-wart 9v supply might be a helpful accessory for the UTEC.

 

This thread needs to be stickied!!!

I udgraded from 2.6 to 2.7 without any troubles, but upgrading to 2.8 sucked!

If I hadn't found this, I was feeling screwed.
On the 2.7 upgrade, I never had to upload the throttle.mot file. This time, I bypassed that step again, and the throttle didn't work.

Here's what I had to do:

I was connected Serial to Serial. (fortunately, my laptop had a docking station with a serial port!)
I followed the manuals instruction and kept getting the same errors as everyone else. I even tried changing the baud rate, but it still failed. After reading this thread, I went back to car.

I opened up the flash program, selected the file, and changed the baud rate to "19200." Then, I flicked the switch on the UTEC, put the key in the ignition, and turned the car on. I uploaded the file perfectly!

After realizing that the throttle didn't work, I came back to this thread and found westpak's instructions!!!! I flicked both switches on the UTEC into the programming mode. I turned on the laptop, opened the flash programmer, selected the throttle file, set the baud rate to "19200", ticked "verify", and then turned the car on. Once the car was on, I uploaded the throttle.mot file perfectly!.

Finally, turn the car off. flip both switches back in the normal mode, and then you can finally start the car!!!!

Thanks for all the help!!!

Again,..MODS PLEASE STICKY THIS THREAD!!!!
