Updated my new vtx8 with the vlink and still cant run my tekin pro4 4600 at 100% punch or 100% power. I cant even run it at 80%. The vtx8 is junk and as stated before it doesnt matter if you call or email them on the issue.
I ran mine for 20 minutes straight at 100 Punch, driving like a crazy beginner full throttle all the time with the Tekin 4600 - gave it to a customer who ran the same set up all weekend at the SC Showdown in MA, almost made the A Main. Others have reported similar improvement with the upgrade, especially when they were experiencing cut offs previously or having to run highly reduced settings.
Verify that when you plug in the ProGauge it shows a61. Also check on the motor- feel the wires connecting to the motor and make sure one is not hotter than the others. How old is the Tekin motor? Did you try a different motor, just to verify? Hate to say there could be a failure someone, but we all know it happens.
