Rather than start another thread about SCT tuners I'll add my thoughts here....
The plug and play upload to the truck is very appealing as all the 'how to' youtube etc films make it look like something a child can do.
Ordered on 24/12 from Torrie, to my surprise was delivered to the UK on 30/12. I hadn't appreciated the custom file would be emailed to me and needed to be loaded to the tuner.
No problem, I'm not an idiot and have access to a computer and laptop, Torrie sent the file within minutes of me emailing the serial number of the machine.
First problem is both my computers are Apple products so I'm now essentially screwed because no software from SCT for these machines - not exactly rare beasts are they....?
A get hold of a PC laptop from a mate running windows 10 and all working fine, (£150) load the SCT Uploader and connect my tuner but they won't talk to one another.
I waste many hours of my time and Torries trying to get this working. Downloading 'windows drivers' and changing loads of the settings on the computer. I'm not too worried about the PC as I've only bought it to get this working.
Lots of worrying messages on the screen, 'are you sure you want to do this?/this is not secure etc, warning', not sure I'd want to risk the contents of my other machines.
Next I pop around my neighbours house, get them to upload the SCT Uploader and try their machine, same thing - won't connect to the tuner. They weren't happy about the on screen messages too but are car people and were keen to see it work, so tried.
So after literally 2 days of poncing about, Torrie has run out of ideas, he tells me to contact tech support at SCT which I did - I've still not heard back after 7 days......
Yesterday another mate of mine who's capable enough to fix PC's, build websites etc spent an hour on it and managed to get it working!
Short version - this isn't quite as easy as you're led to believe, you'll need a windows based PC that you won't mind potentially getting knackered and hope you don't need 'SCT Tech Support', I'll report back if they ever get back to me....
Support from Unleashed Tuning is great and the results are night and day after getting it working.
If you're not very techy and don't have acces to someone that is, I'd insist the tune is loaded to the tuner before they mail it to you.....once the above is done loading to the truck is as easy as it looks!
