The Mini Maxx will ask you very simple and very straight forward questions like pick your truck, tire size and so on. We find that running a simple wire makes for a much better experience for this H&S diesel tuner. After you find where you want the H&S mounted, and you have decided weather or not to run your power wire all there is to do is make sure the memory SD card is in your unit and turn the key. The power box allows you to run a power wire to a HOT on KEY fuse so the mini maxx will turn off and on with your truck, or you can flip a switch and have it on all the time unless you power it down yourself. The HDMI cord (just like whats on your TV) actually plugs into a power box provided and then into your OBD2. So the first step to installing the mini maxx is to locate where on the windshield you want to mount the unit and make sure you have enough HDMI cord to get to you OBD2 port. HIGH QUALITY SUCTION CUP WINDSHIELD MOUNT In fact installing your new mini maxx should take about 30 min and use no special tools. H&S Performance has made adding 100 horsepower and increases MPG and very easy install. How long does it take to install the mini maxx? So the question we keep running into is people want to know how hard it is to install. What I HAVEN'T tried, is disabling PATS in the tune and then jumping the trigger wire! I keep meaning to, but, again, it's a PITA to have to reprogram PATS as you're aware.ÄȘnd my to do list far outweighs my to try list right now.Most people that are serious about diesel horsepower and mileage gains know the H&S Mini Maxx is hands down the best diesel tuner available. Toggling the "enable PATS" setting in MCC doesn't do anything. I bought a non-PATS cluster off of ebay, I just haven't had time to try to install it at a convenient time where I have an IDS on hand. perhaps the cluster is flaking and losing power during the programming cycle? if you cycle power to the cluster (unplug it), you will have to reprogram PATS again. Man, push comes to shove, you might swap a cluster in it. You might re-seat the connectors at the PCM on the firewall for good measure. I don't have big hands or arms, and they're still a PITA for me They're a PITA unless you have bird arms. If not, you might go ahead and re-seat the connectors. See if you can find any evidence of chaffing/rubbing. I'd pay attention to the two main harnesses running in the driver fender well area. Sent from my SAMSUNG-SM-G890A using Tapatalk Anybody at all have any stinking clue what's going on with this! ! ! ! Attempted to start and still no start even using jumper wire, and once again I'm locked out. So I got another tcm installed it and retuned, it completed install and said to start. Not going to name names but it was narrowed down to tcm fried when I originally tuned yesterday. I have spoke with idk how many people who have no idea what's going on. Makes no sense because I have not updated in at least a year. Then I attempted to update firmware and it said it could not update because the current firmware on tuner was newer than what I was trying to load into it. They unlocked it again this morning and I returned it to completely stock, then removed sd card and updated it from h&s. They had trouble getting connected but finally got it unlocked, so I tried to retune again only to be locked out again. Had a no crank and the obd port was blocked, so I carried it to the dealer. Upon attempting to start I had a no start and then the PATS system completely locked it down. Well I tried to change tunes yesterday, it completed and said to start vehicle. It is an actual off-road tuner, and have changed tunes numerous times with no issues. Ok I have a 2010 6.4 that I have had ******d with my mini max for over a year and half.
