Just traded in my 2011 sport on a 2015 jkru. I had a 3570 on my sport and loved it. I've looked up several different posts on whether or not this programmer will allow me to lock the axles in 4h not just 4l. Some say yes while others say no. Has anyone of you been able to use their 3570 to do just that? I know this yr of jk requires a ecm upgrade for performance so the only other benefit of having it for me is the locker option. The jeep is,stock at this point

Tire size
Axle ratio
DLR
Idle speed
TPMS

Thats all I could touch 15 JKUHR

Oh and Horn chirps and ACC delay

Thanks AZ I didn't want to try and mess with it if I couldn't lock up,the diffs in 4h so I guess I'll get rid of it. Still happy with the jeep though

You can always do the bypass mod. Pretty simple if you can do some basic wiring.

Wasn't aware of the bypass. I'll look into that. This is why I love the forums

i advise using the grounded relay method. Because the relay back feeds 12volts until grounded so if you are using an illuminated rocker switch it won't light up correctly without another relay between the switch and locker relay.
