5.With Unlocked PCM installed, connect TD2 to Vehicle.

a.Navigate to Performance Menu option from pull up menu

b.Select a performance tuning level

c.Tuner will read PCM and continue tuning your vehicle. You will need to follow device screen prompts from this point forward.** (When prompted for Ignition ON, be sure double tap on push start and check to see run illuminated on push start itself)

On first power up with an Unlocked PCM, the cluster panel will illuminate the red security light and may warn about other module errors (Traction Control, ABS, etc.). This is not abnormal and part of the process.

When you begin to tune and are prompted to turn the Ignition On, the cluster panel should no longer have the red security light illuminated which signals that your JL has been programmed, and connected, to the Unlocked PCM.

After installing your tune, start the vehicle. Let the vehicle run for more than 3 seconds, and test throttle response. The vehicle shutting off after ~3 seconds, or having a dead pedal indicates that there was an issue reading stock data and/or writing stock data to unlocked PCM. If throttle response is good and vehicle stays running, please continue by shutting off engine, returning ignition to ON.

TrailDash2 for Jeep® JL Wrangler® is rated 4.0 out of 5 by 3.
Rated 3 out of 5 by from Works as advertised. Installation is horrible The product works well. However, the pcm swap is not as easy as the company states, especially for the 2018 Jeep Wrangler Jl. There are videos online that can walk you through a swap out. However the video is for a JK. In the JL. Furthermore, the directions in the video differ than the written directions. The video states to remove the positive lead from the battery. However, the written directions state to remove the negative lead. Furthermore, the video stated a 8 mm wrench is needed to remove bolts. The reality is a 10 mm wrench is needed. Unless you have the hand size of a small child, it is nearly impossible to switch out the pcm unit.

Rated 5 out of 5 by from Extra power! The directions need to be updated and install a little challenging but with the help of Superchips tech support this thing works great and adds a lot of extra power not to mention I was able to calibrate my 40 inch tires and 5:13 gears for my jlu. Easy to use once installed and has tons of great features .

Rated 4 out of 5 by from Good System for The JL Swapping out the PCM on the JL takes patience and a few standard, good tools to get in tight places. Three bolts and two electrical connectors and it’s off. The bolt closest to the front of the Jeep is the toughest to deal with. Moving the air intake hose out of your way will make the swap a lot easier with that one bolt. Your top left hand is going to get cut up if you don’t wear gloves. Superchips needs to improve the pcm mechanical swap out directions for the JL. As far as programming the pcm, follow all the Superchips directions in order and you will get it right the first time. Set up was a breeze and without surprises. Being able to monitor various Jeep vital signs at one time is very useful. Setting up for the 35 inch tire size was spot on and the speedometer is right on the mark according to my gps. I have programmed for 87 octane only so far because that’s what I have in the tank. I don’t plan on using the higher 91 octane tune at the moment. The 87 tune is nice. Good throttle response, good shifts, no issues. I knocked off one star because of the poor intstall instructions. So be patient with the pcm install. Follow the programming directions in order. Enjoy new capabilities with your Jeep JL. Danelizer

Will this allow you to engage or disable the front and rear lockers? Is that same feature enabled on the F5 Flashpaq for 2018 Jeep® JL Wrangler® - 3876-JL?

Asked by: Evang
We do not offer axle lock on the JL unfortunately

Asked by: Jebb
This will not. We are still working on 2.0 tuning. Check back with us shortly

Will this also turn on factory aux switches for the jl 

Asked by: Jebb
This will not control any factory switches in the vehicle. You can use our power switch with this monitor to control aftermarket electronics
