Looking to upgrade scangauge

I have a SG2, want either a 3 or this one:

$125 Lufi Xs Obd2 Gauge Display,car inclinometer, Boost Gauge, RPM Meter, Multifunction Heads up Display Cluster

https://www.amazon.com/Lufi-Display-Speedometer-inclinometer-Multifunction/dp/B0BM528LKF

Anyone tried the lufi yet? Basically just want it for the water alarm feature and its cheaper than a SG3. thoughts?

 

On the 2nd page to the right on listing it says Toyota 2005 up models?

 

thats just them covering their a$$. anything 1996 or newer is obdII but that is why i'm asking...

Probably means it can only communicate on CAN which 1st gens don't have.

 

OBDII is a standard which all passenger vehicles built after 96 must comply with but there are different communication protocols, starting around 05 the CAN (Controller Area Network) protocol started being phased in. As of 08 all vehicles are required to use the CAN protocol for Global OBDII functions, prior to that several other protocols were used.
I'm thinking since they are advertising that as 05+ it only supports CAN.

 

I think too many users hates the build quality anyway. I'll get a SG3 eventually.

 

I like mine

 

Sweet thats cool, hey good photo op, hey I'm missing one of the little 12v port dust caps. I was actually looking lately for an original, no luck. Any suggestions anybody. Nice guage

I drive alot bugs the crap outta me when it doesn't have a phone charger on it

Sorry I don't. I'm pretty low on parts right now.

 

Old android tablet + torque pro will outperform for half the cost. 1st gen OBDII ports are just too slow imo

 

So what does TorquePro connect to if not OBDII?

 

its magic.....

 

I guess hard connect is worst compared to wifi

 

Sorry, guess I left that thought incomplete. I'm saying it's kind of useless to get better performance from the OBDII port because the J spec is so slow. If you want fancy graphics though, dirt cheap options exist

 

So what performance are you expecting if you just need numeric vs the dummy needle gauge?

 

I have no idea what you're getting at..

 

trying to understand the performance aspect as stated

 

I mean why upgrade unless you want something to perform better? To me all of them are a waste of time because it takes too long to update fast values like RPM. The bottleneck is the OBDII spec and I'm just saying nothing will fix that. So the only thing left is the visuals, which a tablet can handle... Though have a laggy startup
