Tuners for Jeep Wrangler JK – FAQ, Features & Buyer’s Guide!

Best Tuner for Jeep Wrangler JK
Written by Jim Malkovich

The Wrangler is a vehicle manufactured under brand Jeep that belongs to the SUV segment. Designed for driving on very rough terrains, it belongs to a series of widely known vehicles from World War II, i.e., Willys MB models.

1987 is considered to be the year of the Wrangler’s civil stage life start when Chrysler took over the brand. Today, the intermediate owner is Italian-American corporation Fiat Chrysler Automobiles, along with a few private investors. SUVs are still the Jeep’s primary production trend. The most famous models in the range are Wrangler, Cherokee, and Grand Cherokee. The headquarters is located in Toledo, Ohio, United States.

So far, three Jeep generations have been created, introduced to the market every ten years or so. The design concept of the bodywork hasn’t changed much since World War II, as mentioned earlier.

Chip tuning of a Jeep Wrangler’s diesel engine allows for a good torque boost quite fast, and you can reduce fuel consumption by 10-15% with a quiet/highway ride. When working with a Jeep Wrangler’s engine, you can order additional services like removing the particulate filter, EGR recirculation system, diluent air, or crankcase ventilation with only +10% extra charge.

Jeep’s gasoline engine chip-tuning can add up to 5-10% of power in the atmospheric version and about 30% with the turbocharger. Turbocharging is regulated by the ECU, and the tuning program allows you to unlock the potential of the engine, low turbo lag and fast spool times, and provide more horsepower as well as smoother traction. Catalyst removal and tuning versions of Stage-2 are available for several engines with even higher power gain.

What happens when the engine gets chipped?

Well, these days, they don’t actually chip anymore – the new firmware is uploaded straight into the vehicle’s ECU via the OBDII port. In the past, mechanics would actually desolder a chip, write a binary code of the firmware through a programmer, and solder it back.

In the firmware, various parameters, including pressure charging, advanced fuel injection timing, etc. are changed. Usually, all the changes are made within safe limits for the engine (+10-20%).

It looks kind of like this:

A dude (tuner) with a mini-device (programmer) connects to your vehicle’s OBD II port via cable, downloads stock firmware, and uploads new. Sometimes, it may be necessary to adapt the firmware to the vehicle, but usually, the firmware is made individually for each car.

In fact, the fuel cards and boost parameters, etc., remain the same; the adaptation is necessary to link the blocks to each other. Prescribe VIN-codes, different module codes to be accepted by the main module and other individual parameters. Roughly speaking, it’s like installing drivers for all equipment of the system.

Adaptation is performed through a special software on a computer (firmware file is getting edited), or through a dealer diagnostic computer via the data bus. After reflashing, parameters like advanced fuel injection timing, shift points, and exhaust gas temperature remain essential – these can destroy your engine quickly and ruthlessly.

Before you get to the list of top tuners for Jeep Wrangler JK, make sure you know what you are looking for and if your Jeep is ready to get tuned. Because the devices below represent some of the most considerable modifications, and once you try them, there’s no way back.

Proceed with caution.

HP Tuners MPVI2 M02-000-00 Tuner for 3.6L/220 Jeep Wrangler JK

HP Tuners MPVI2 M02-000-00

The MPVI2 unit is the next model that replaces no longer available MPVI Pro and MPVI standard units. The new device is one of the most potent scanning and calibration tools on the market. It’s fast and beneficial in terms of logging and data transmission rates to make sure that you didn’t miss a thing.

The MPVI2 has a much sleeker, modern look and is more compact for your convenience, and it, of course, comes with many more cool and useful features.

You can read and adjust various parameters like torque strategy, fueling, RPM limits, cooling fan, shift points, speedometer, etc. using the included VCM Editor. Then there’s also the VCM Scanner, which allows you to command and view many control functions and parameters in real-time as well as clear diagnostic trouble codes and log diagnostic data via the OBDII port.

The MPVI2 is cheaper than its predecessors. However, it comes with no pre-loaded universal credits (virtual units) for tuning/programming. This means you will have to buy credits first to be able to license your vehicle, which is mandatory for uploading your custom tunes back into your vehicle’s computer. Make sure you purchase universal credits from an authorized HP Tuner dealer; otherwise, the device will not be warranty-covered.

You can pull a tune file out of the vehicle using the HP tuner and the included software, save that tune file, modify it using your PC, save it again. Still, you will not be able to upload the tune back to your vehicle’s computer if you don’t have any credits.

BTW, universal credits can be applied to any vehicle on the Supported Vehicles List on the hptuners.com. And that’s where you can also check how many credits your Jeep needs to get the license. In the case of 07-18 Jeep Wrangler JK, it’s 2 universal credits (as for now).

FAQ

Can you tune a Jeep Wrangler?

Yes. Jeeps are all about climbing and off-road performance, so if you think you can turn your Wrangler JK into a dragster, well, that’s hardly possible. The vehicle weighs about 4.900 lbs and has brick-like aerodynamics.

Modern Wranglers produce about 285 HP and 260 lb-ft of TQ and are designed to be ultimate all-terrain vehicles. You can tune your vehicle’s computer and improve your air/fuel ratio, timing, horsepower, torque, tires, shift points (if your transmission is automatic), etc.

You can get access to various tuning options and modes, as well as some significant power gains of up to +30 HP. Just make sure you know how to set your tuner up correctly – if you have any doubts, better let an expert tuner to do the job for you.

Sometimes, you will also need to make adjustments to engine calibration. Otherwise, you will not get the performance you need. You can also buy a replacement cat-back system, cold air intake, snorkel system, or upgrade your injector to increase your vehicle’s power.

What is a Jeep Superchip?

A Flashpaq F5 from Superchips is an ultimate performance programmer for Jeep Wrangler TJ and JK models that comes packed with various tune files and features for additional power and utility. Many Wrangler owners recommend this tuner as their number one choice when it comes to boosting the performance of any TJ or JK Wrangler.

How can I get more horsepower out of my Jeep Wrangler?

Well, you need to optimize your vehicle’s combustion engine performance, obviously. Getting a new high-flow air intake filter to “feed” bigger amounts of colder/denser air to your engine (+15-20 HP), larger-diameter replacement exhaust system for expelling spent exhaust gases faster (+20-30 HP), and, of course, a nice functional programmer/tuner with a user-friendly interface is also a good idea. You can also get a chip and connect it to the wire harness to gain up to +35 HP.

A performance tuner/programmer/chip will optimize your engine performance, i.e., you will be able to adjust your air/fuel ratio, improve fuel mileage (up to 5 MPG), and achieve complete control over your vehicle. You will be able to improve your RPMs, fuel pressure, exhaust gas temperature, and transmission shift points. 

You can also add lifts and tires or spend a few k’s to get yourself a supercharger kit which will allow you to shove more air into the intake tube and get a guaranteed result of 90+ ponies, but the prices for the device are just crazy.  

What is the best performance programmer for Jeep Wrangler?

Superchips is known to produce the best, easy-to-use and install, powerful, and functional tuners packed with various tuning programs and features for Jeep Wrangler JK. You can update your transmission shift points and change your tire size to feel the difference. Choose between the Superchips 42050 TrailDash 2 Programmer (2015-2017 JK), 3571 Flashcal F5 Tuner (2007-2018 JK), Bully Dog 40417 GT Platinum Diagnostic and Performance Tuner (2012-2014 JK). DiabloSports and HP Tuners also have great options for Jeep Wrangler JK.

Conclusion

If you don’t have enough experience in tuning and/or not sure you can tune-up your Wrangler’s engine by yourself, then choose tuning shop wisely and don’t rush to trust the first one you visit. Read reviews, learn more about their service quality, ask your friends, read the forums, and don’t have high expectations.

No tuner will tell you how much the advanced fuel injection timing changes (and if it changes at all), the same goes for exhaust temperature limits, fuel injection, etc. They will tell you there were no complaints before, everything is optimized, and the firmware was written by specialists. It’s as if you would want to know the exact sweetness/acidity of apples in a grocery store…

Imagine, you come to a grocery store and ask the sellers, “Guys, I need an expensive delicacy, do you guarantee its ID? Does it taste good? Is it the same as in commercials?” Most probably, you will hear something like, “Sir, it’s a real delicacy… It’s delicious! However, we’ll give it to you in weightlessness (so as not to determine the weight) and in a dark room… Then you will take it home and taste it there. But we guarantee that you will be full!

There were no complaints about the delicacy; no one was poisoned (yet), and the product is hand-made by the best European chefs. And if you vomit, you will get your money back!” Finally, you realize that you can eat something wrong, get full, and sh*t your pants.
