Did you buy the $EE file for $19.95? Gotta have the definition file to run Winflash. Also you need the new bin file that you created with tunerpro so winflash can upload it to your pcm.
The gearheadefi forum has many different lt1 based bin files you can download to use with winflash. That is if you haven't created your own new bin file with tunerpro.
When all else fails contact the people at tunercat. They are very helpful and know much more than I about the operation of winflash and tunercat obd 1 tuner.
If you want the tunercat obd 1 tuner, on the lonk you provided, go down list to "obd 1 tuner" Hit that, when new page opens, scroll down to bottom of page and hit the download now tab. Pop up will appear to download the 30 day trial of the obd 1 tuner. Keep in mind to read your lt1 pcm, you will need the $EE definition file.
On the first link you put in post, when it opens, scroll down to chevy cars. At bottom of list, you will find $EE def file. Hit the add to cart button. Once you pay for it, tunercat will e-mail the file & serial number to unlock file. There should be an instruction doc to show you how to add the def file to winflash or obd 1 tuner.
