Group 1: Best OBD2 Scanner with Crankshaft Relearn

#1. LAUNCH X431 V Pro: Best for case relearn

Launch X431 V Pro stands out as one of the most powerful devices available for relearning purposes.

I’ve had the opportunity to connect and use this tool on various vehicles, ranging from 1998 to 2020 models. 

It performed flawlessly during crankshaft position sensor relearn on GM vehicles such as:

• 2008 Chevy 2500HD, 
• 2002 Chevy S10, 
• and 2004 Silverado. 

I have yet to encounter a car that it couldn’t handle.

Besides its excellent performance on crankshaft position sensors, this powerful scan tool also supports:

• CVT transmission relearn, 
• CAM relearn, 
• and TPMS relearn (requires TSGUN tool).

If you’re looking for a scanner with comprehensive relearn capabilities, Launch X431 V Pro is a top-notch option to consider.

Regarding design, though the screen size is a bit smaller than expected, the overall build quality of the Launch X431 V Pro is excellent. 

The tablet itself runs on Android with Launch diagnostic software. The powerful software ensures smooth and responsive performance even during heavy-duty tasks like full-system diagnostics, active tests, or key programming.

To put it simply, the Launch X431 V offers an incredible value of about $800.

#2. XTOOL D7: Best for transmission relearn

XTOOL D7 is an absolute must-have for relearn tasks! Whether it’s transmission relearn, crankshaft position sensor relearn, or throttle body relearn, it handles them all flawlessly.

This scanner also works perfectly with every car I tested for transmission relearn. So I was blown away by its wide coverage,

But what’s truly remarkable is its extensive list of advanced functions. From active tests to 36+ reset functions, key programming, or even ECU coding for VAGs – the D7 can do it all!

The versatility of the XTOOL D7 makes it a true money-saver. 

Yes, it may require an initial investment of around $450-$500. But consider this: a dealership charges $200-$300 just to program a new key fob for your car. 

So with the XTOOL D7, you can do it yourself and watch it pay for itself in no time. 

Sure, some may consider it a bit spendy, but trust me, the value it provides is unparalleled. The peace of mind and the convenience it offers are truly priceless.

If you have any questions, don’t hesitate to email Xtool. Their support team is in China, so it might take a little bit to get answers depending on your time zone, but they do get back to you within 24hrs.

I have to say, this product deserves a solid 5-star review from me. And I’m confident you’ll feel the same way after using it for a short time.

#3. LAUNCH X431 for GM: Best GM scan tool with relearn capabilities

I got my hands on the Launch X431 scanner primarily to handle crank relearns for the GM cars in my shop. 

Trust me, if you own a Chevy, Buick, Cadillac, GMC, or any other GM brand, the crankshaft sensor relearn is crucial, especially after changing the engine computer. 

And I must say, this scanner didn’t let me down.

I’ve used it countless times on various models like Chevy Silverado, Chevy Malibu, Pontiac, and more. The Launch X431 supports every car I’ve come across so far. 

But it’s always a good idea to double-check the vehicle coverage with the seller before buying to ensure it’s compatible with your specific cars.

You wouldn’t believe the number of things this little adapter can do! From basic full-system diagnostics to more complicated tasks like key programming and active tests, this scanner can handle it all.

If you were to find a scanner with this many features elsewhere, it would easily cost you $500 or more. 

But Launch X431 Elite offers all that at a super affordable price, under $200! It’s the perfect choice if you’re looking for a scanner with relearn capacities for GM cars without breaking the bank. 

In fact, I dare say it can handle the most challenging tasks that an $800 Launch X431 V Pro can do, but at just a quarter of the price!

So, if you’re looking for an efficient and budget-friendly scanner for your GM cars, don’t think twice – the Launch X431 Elite has your back! It’s a fantastic investment for DIY enthusiast.

Group 2: Other Best OBD2 Scanner with Relearn Capabilities

#1. LAUNCH CRP123X Elite: Best for throttle body relearn

If you’re on the hunt for an affordable scanner that does a great job with throttle relearn, look no further than the Launch CRP123X!

This scanner can easily relearn the throttle body for most cars across various brands, as long as they’re from 1996 or newer. 

One of the things I love about this tool is how it simplifies idle relearn. 

Using it is a breeze, and I can reset the throttle body in under a minute – super convenient!

After installing a new throttle position sensor or cleaning the throttle body, the computer sometimes doesn’t relearn on its own. But with the Launch CRP123X, the problem is solved!

I even used it to diagnose the check engine light, and it quickly pinpointed a faulty O2 sensor. The scanner lets you input the check engine code, and it smartly tells you the most likely cause, saving time and eliminating guesswork.

Live data graphing is another big plus for this scanner. You can see up to four live data streams simultaneously, like O2 sensor readings, engine coolant temp, RPMs, and fuel trim levels. It’s super handy to have all that information at a glance.

However, I must admit that the instruction manual could use some improvement. It took a bit of trial and error to figure out how to use the scanner effectively. But once I got the hang of it, it became an invaluable tool in quickly identifying and addressing problems.

The scanner’s design is surprisingly impressive, featuring a user-friendly touchscreen. Now, updating is a breeze – just a simple touch, and you’re good to go! This feature sets Launch CRP123X apart from other cheap scanners.

Having the throttle reset function in a scanner like Launch CRP123X can save you a ton of money. Imagine not having to pay $120/hr for a throttle body reset at the mechanic’s and avoiding potential future issues altogether. 

This scanner is truly a cost-effective investment for any car owner.

#2. XTOOL InPlus IP819: Cheapest scanner with full relearn capabilities

 XTOOL Inplus IP819 is a versatile device designed to enhance your automotive maintenance experience.

First things first, this scanner comes with more than 31 service functions! So no matter what relearn function you’re looking for:

• Crankshaft position relearn, 
• Transmission relearn,
• or Throttle relearn (idle relearn). 

This scanner’s got your back.

Another standout feature is the powerful IMMO/Key Programming capability. It can disable lost keys and efficiently program new replacement key fobs. This will save you a significant amount of money in the near future.

Now, for all VW car owners, I believe you’ll love the ECU coding function. It lets you customize your car settings.

Therefore, you can disable those annoying functions or enable the hidden ones to unlock some higher-level car performance. How cool is that?

An attractive bonus is that the XTOOL Inplus IP819 offers 3 years of free updates. For those familiar with OBD2 scanner brands, you’ll know that a 3-year free update package is a rarity. This means you’ll have 1-2 extra years of cost-free updates, helping you save approximately $169 per year.

So, if you want a reliable, versatile scanner that has your back for years to come, look no further than the XTOOL Inplus IP819. It’s a real game-changer, and I can’t recommend it enough!
