Superchips 3571 Flashcal F5 Tuner Review

So do you have a late model Jeep? If you tend to tweak its configurations or upgrade its accessories and tires, then you’ll need a programmer tool to interface with the onboard computer. For many, the right tool is the handheld Superchips 3571 Flashcal F5 Tuner.

Features of the Flashcal 3571

This is the latest of the Flashcal handheld programming tools from Superchips, and it’s an upgrade for the 3570. Here’s an updated list of what it can do:

  • Depending on the make and model (and the aftermarket goodies), you can set various features.
  • If you’ve changed the tires, you can inform the computer so that it can correct the speedometer. The corrections can accommodate tire sizes from 26 to 42 inches.
  • It can also recalibrate the speedometer for gear or axle swaps up to 5.38.
  • It can adjust the engine idling rev for winching.
  • It offers a one touch lane change that automatically ends the change lane signal after a number of blinks.
  • It can turn the tire pressure monitoring system on or off.
  • When you’re locking the door with keyless entry, some of the accompanying options can be configured by the 3571. It can adjust the chirping of the horn and the exterior lighting flash.
  • The programmer can read and clear diagnostic trouble codes, which can help a lot. It can warn you of specific issues, which can be very convenient right before an inspection. You won’t have to buy a separate diagnostic interface and download an app or laptop software.
  • For 2007 to 2016 models, it can help you adjust the daytime running light options.
  • For 2011 to 2016 models, you can also set various delay options. Aside from the headlamp delay, the adjustable delay can be set for various accessories. These include accessory lights, radios, and other aftermarket goodies you’ve tied to the same fuse.
  • For the 2007 to 2016 Rubicon, you can also adjust the locking axle options.
  • For the JK only, you can tune the crawl for low speed off-roading in 4-wheel drive.
  • The 3571 is Internet upgradeable—so if you want you can just upgrade its features when Jeep releases new features for the handheld programmer. In fact, you can download features from online so that the Flashcal you have can work as a Flashpaq.

Pros

  • It’s very easy to use. It’s much like using an mp3 player, with a large screen at the top half plus on the bottom you have directional and enter buttons. You just need to navigate through the various options and enter your choices. Then the computer will make its adjustments automatically.
  • In a way, it’s also like having a Windows tweaker program that allows you to customize various display and configuration options more easily. It highlights just how inefficiently you can do this with the stock onboard computer and display. It shows you a better, faster, and more logical way of customizing the various options to fit your preferences.
  • If you’re a fan of putting in modifications to your Jeep, then you really need this. The thing with modern Jeeps is that when you change things, there aren’t any sensors to notice the changes. That’s why the speedometer becomes a bit “off” when you get bigger tires. But with the 3571, you can update the onboard computer to take into account every modification you perform.
  • The screen is terrific, and you can just plug it in and it will show you a variety of live gauges. Or you can go through the many options and find the data you’re looking for. You can find miscellaneous info for engine and non-engine components. You can see fuel trim data, time and distance covered, oxygen sensor data, EGR/Evap info, catalyst temperature, and throttle detail.

In one screen, you can also see the precise engine rpm, the intake air temperature, engine coolant temperature, and the ambient temperature.

  • If you’re using it for a specific programming change, it’s very quick and easy. So let’s say you got bigger tires for your jeep and now you want to recalibrate the speedometer. Instead of having to go to your dealer, you can do that with the 3571 on your own. And it won’t even take long—10 seconds will do just fine.
  • It will also help improve any sluggishness in the acceleration when you go with bigger tires.
  • The customer support personnel are also professional and very helpful. They really do answer the phone.

Cons

  • The price may be a bit too much for some, especially when you only need to use it once. But then it’s much better anyway than having to go to a dealer for the same service.
  • You can only use it for one vehicle. It’s locked in by your VIN, so there’s no chance that you can lend it out to a friend. You will have to unload its programming before you can do that.

Comparison

Since the 3571 is an upgrade of the 3570, any head to head comparison will have the 3571 ahead. The main difference is that the 3570 isn’t configured to handle the newer jeeps. There’s the Flashpaq with more advanced features, but it costs almost double that of the Flashcal.

You may want to look at the AEV ProCal Module wits similar features. But the Flashcal seems easier to use.

Verdict

This is obviously a much better buy than the 3570, and that’s especially true if you have a newer Jeep that the 3570 isn’t designed for. Now you may think that the Flashpaq is better, and it is if you don’t take the price into account. But then the cost of the Flashpaq is too much. At least with the Flaschcal, you can just upgrade the program in the unit and it can have the same features as the Flashpaq.

As for the AEV ProCal Module for 2007-17 Jeep Wrangler and the Wrangler unlimited, it doesn’t quite match the efficiency of the 3571. On almost all fronts, the 3571 feels just a bit better.

The Flashcal 3571 covers lots of Jeep Wranglers since 2007. It offers a lot of programming features, and it’s easy to use. The customer support is terrific. It does seem like the Superchips 3571 Flashcal F5 Tuner is the more sensible choice.
