Weird. I would contact their support if you haven’t already.
I drove it for about 2 hours yesterday but i think i should hook up my battery tender while I tune it just to make sure. Will the car be ok with it in start mode with a battery tender connected?I don't know if it's causing your problem, but either way, I would put a battery charger on the car since it hasn't been run for a while. Especially since this is the first time you're tuning it because the SCT will need to copy the stock tune first.
Yes, it will be ok.I drove it for about 2 hours yesterday but i think i should hook up my battery tender while I tune it just to make sure. Will the car be ok with it in start mode with a battery tender connected?
