Looking For Thoughts on Tazer vs JScan

[MRH512]

I just put a set of take-off XR wheels & tires on my 2020 JLUR and want to use a Tazer/JScan to update the tire size (33 to 35) so it goes back to shifting properly; that's it. I might turn off the TPMS but can't picture myself doing much else with it.

Anyone have a recommendation on which is better for the simpler stuff like this?

Thanks in advance,
Matt

JSCAN....

Simple route is the JSCAN if you did not intended to use any of the other features that the Tazer would give you.

Tazer has some great options but JScan is easier to use and about 1/3 cheaper. It was a pretty easy choice for me.

Yep. Like the rest said. JScan. It will do all you are wanting for a fraction of the cost of a Tazer.

IF you do opt to go with JSCAN, do read all of the pages in this thread.

Take heed the part about not buying Chrylser cables but instead buy a dedicated security gateway bypass module... Also to go with the less expensive VLINKER MC+ rather then the OBDLink MX+ OBD2 Bluetooth Scanner.

If you don't need/care about the Live features of the Tazer, JSCAN will do everything the Tazer will do as far as I know. It's also significantly less expensive.

I've had both and just stuck with JSCAN as my needs are pretty basic and I would never use the Tazer live features (at least not that I can foresee right now).

Plus, with the JScan you make the changes and it updates the computer in your Jeep, you then unplug it and it holds that info. The Tazer has to be plugged in all the time to work.

Hey Matt, what part of Texas? I have the hardware you can use, would just need a license for JScan.

@Apexcars

Your post is a bit misleading..

The Tazer JL in regards to similar things you would program with JSCAN does not need to be "plugged in all the time to work".

The Tazer JL only has to be plugged in if you are using/wanting to use, live features that the Tazer JL provides (and that JSCAN can not and does not offer/facilitate)

JSCAN does not provides/offer live features as a Tazer JL does.

Thanks for that clarification, I wasn’t aware of that. I thought you had to un-marry the Tazer if you wanted to disconnect it. Thanks again for straightening that out for me.

You should unmarry the Tazer if you take it in for service. That restores all the factory settings. Problem is then you have to go back and re-enter all your changes once you get it back.

Agree! The easiest way to think about how JSCAN works is that it is the "lite personal" version of the dealer system where you can make changes to most any setting related to the most common systems. The settings are changed and saved and then JSCAN is disconnected (leaving no footprints behind).

You can change things like this:

– Access generic diagnostic trouble codes. (Read/Clear).
– Access manufacturer specific diagnostic trouble codes at all available modules (Read/Clear).
– Access generic live data from all available sensors.
– Access manufacturer specific live data from all sensors from all available modules.
– Testing/Activation of vehicle specific relays, lights, actuators and more
– Read Module identification data, VIN, Part Number, Version etc.
– Read VIN information.
– Programming vehicle settings such as:

* Tire Size​

* Axle Ratio​

* Transfer Case Low & High Ratio settings​

* Fog Lights with high beam lamps On/Off​

* Tire Pressure Monitoring (TPMS) On/Off – intended for Off-Road use only​

* Tire Pressure Monitoring (TPMS) Settings – intended for Off-Road use only​

* Rear Camera Activation​

* Front Camera Activation​

* Day Time Running Lights (DRL) settings – location, configuration, voltage etc…​

* Day Time Running Lights Dropout On/Off​

* Fog lights front & rear Enable On/Off​

* One touch line change On/Off​

* Tow Settings – Enable / Disable Tow relays and Trailer Modules​

* Change Parktronic PTS configuration – Front & Rear, Rear, None​

* Panic Button On/Off​

* LED Lights conversions – turn signals, main lamps, stop, etc…​

* Lights US<->Euro spec conversions – disable combined rear lights and more​

* Hood Alarm On/Off​

* Seatbelt alert​

Actually a gal or guy that is really into JL/JT mods... gearing and more is wise ... will have a more pleasant, more feature packed, less headache filled journey lets call it, using both a Tazer JL and JSCAN concurrently.
