Tazer versus JScan

[Terrymo]

I know a little less than nothing about the Jscan, haven’t even seen one…so I’m not here for the debate. And since I can’t figure out how to post gifs using my iPhone ( feels like the mods were targeting me when they made the changes…), I’m not here for the fun …… that leaves the boring ass Q&A 🥱……

My question is, can you use lockers in 4H or rear lockers in 2WD, and disconnect the sway bar nanny free (have it not be speed limited) with the Jscan ?

I have both. JSCAN is useful to a point. Tazer has more features In my opinion. . Some of the functions alleged to work by JSCAN are questionable, Plus if you want to throw an impromptu rave in your garage…lightshow!

@Terrymo

Actually, JSCAN does have live functions. Go to the "Live Data" or "Trail View" screen within the app.

Ok my mistake, I’ll correct my post. I was thinking of the list of live functions the Tazer has that JSCAN doesn’t.

I like using both.

I use Tazer purely as a SGW bypass, and for its live functions. I don't even bother "marrying" it, as that's not really necessary if you only use its live functions.

I use JScan for all my permanent vehicle settings (tow package activation, aux switch activation, tire size, etc) because, unlike Tazer, the settings really stay permanent. You don't lose them if you unmarry or uninstall anything.

So when you take it to the dealer they can see all the changes you made with the JScan.
That is the point of unmarrying the Tazer, a quick easy way to put everything back to stock so the dealer has no idea you were in there.
Personally I hate the idea of a bunch of wireless crap attaching my phone to my Jeep. Uconnect is bad enough and for that same reason I have not activated or connected the Jeep App …..

This overview is incorrect. When a dealership Tech hooks up the WiTech2 it's not like up pops a screen that shows changes made with say JSCAN, Tazer JL, Superchips, etc..

Yes, if a Tech is savvy enough (97% aren't) and has a chitt load of time on his hands, he can see listed, items toggled on and off but it is not easily or readily apparent by whom or with what the changes were made..

Anyway comments saying because Tazer JL unmarries, etc., etc. that Tazer JL is a better way to go then JSCAN are not valid/are unfounded.

No, I am not speculating... I know what I mention to be factual.
Yes, I am pro both Tazer JL and JSCAN and am knowledgeable in regard to both offerings.

Sorry, brief side track. Why do you need/want to stop sway bar speed limiting. I actually find it useful on mountain "roads" when things smooth out (I'm paying zero attention to speed).

Your other interests in drive wheel control make sense, at least sometimes.

I meant the ability to disconnect the Rubi electro sway bar, and not have it reconnect once you get over 20 mph….(i can do this with the TazerI)…. I often disconnect my sway bar on some of our highways that are barley smoother than the fire roads we travel….Sorry, I don’t always explain things very well….

Multiple times over the last few trips I wish I had set the sway bar kill button on roads that were trash and not aired down but still wanting to move 30mph or more

If it comes to a warranty issue they will see what’s changed as they look for problems. Your choice, your money, your Jeep, just my opinion.

My reply to use was just to point out there is no difference whether you use a Tazer JL you unmarry or JSCAN, ECRI, Superchips, etc.


At a dealership level, searching to see if something has been ticked off/on or not, is not as easy as you may think..

Even then, if the Tech could easily hunt down (he/she can't)..... he/she will not be able to tell easily if say another dealership did the tick/the enable, etc.. YES, if Stellantis gets involved they can more then likely make a determination who did the tick.

Anyway, regardless of whether you use a Tazer JL, JSCAN, ECRI Device, Superchips device or whatever, you should remove the hardware / unmarry, etc. before a dealership visit. THEN, always always keep your mouth shut when at dealership if someone says / asks if you have used a device to alter settings. Plausible deniability.. Never admit /say you have used such a device. They have the burden to prove otherwise which is not that easy a task. Just, be smart and uninstall/unmarry/remove such a device before a dealership visit. Indeed, In the end though, you are fair game lets say....

Been having buggers with the TPMS not recognizing the new (w/different IDs) tire sensors. It recognized one even though the ID was wrong. Jscan provided the ability to enter the current sensor IDs an all tires. TPMS light is now off.

FYI, that issue also triggered a code for SOS calling failure. Have not touched that button ever. Indicated see dealer for service on the 12" display. That too is no longer present. Jscan may be limited, but for $30 it is a good purchase..

So…. Can Jscan do the things I asked about or no ?

 

[CO2Wrangler]

I don't think JSCAN can disable auto start/stop. That's why I got the Tazer. I now also have JSCAN because I needed it to re-program some stuff when replacing the engine.

This and the Tazer seems more reliable at allowing the sway bar to be disconnected at higher speeds and in 2wd. I'm limping through that with JScan right now, but most of the time it's just aggravating.

Mostly I just have the Tazer installed still because it's working and I'm afraid of change.

 

[Roky]

That JScan has useful features while the vehicle is on/running ("live") is an important point, since many may be led to believe by various forum posts that its only use is changing vehicle settings.

However, the way I'd phrase it is JScan has live features (that display vehicle data), whereas Tazer has live functions (that intercept/spoof CAN bus messages to alter vehicle behavior). Perhaps, I'm being pedantic.

Perhaps…… nonetheless, based on what I’ve read, I’ll have no use for the Jscan….

So what Im hearing is because you are trying to do more than factory adjustments you need the Tazer ... its almost like Ive heard that in this thread before
