Entune Premium reboot after battery is disconnected

Getting ready to install a CAI on my 2017 TRD Pro. I have to disconnect the battery as per instructions.
What if any effect will this have on the Entune system and will I need to initialize the total system ?

Thanks in advance!

disconnecting the battery will cause problems if more than 10 min.. CAI will not help this engine in any way .. its a V6 engine low power .. if you have a 400HP or higher and you bring to track then it is a good add on ..

pure waste of you $$$ and time ...useless

 

Wow!
Thanks for your input but not entirely accurate!
My friend has same truck and installed same unit I am. MPG and throttle response improved.
And please don’t comment on what I do with my time and money!

 

you my boss ? I just made a comment on your install .. you want to give a child in china some work I do not care at all.. this is not gonna do anything this is a low power V6 engine .. even a 5.7L engine this does not do anything ..
air intake is very large on these so CAI is not gonna do anything . might create more noise when you floor it .

you can get for about $800 a PCM that will increase HP and also the use of 93 octane .. company is in maryland .
that will increase HP to about 40-50HP ..

to give that china child more work install a dual exhaust with 3 inch pipes ...

 

You are correct sir!

 

Bro enjoy your CAI intake I do and when you punch the gas it sounds LeBron James coming down the lane dunking on fools lol. I didn't have any issues when I reconnected my battery.

 

Lame man,
Way lame


What is the main issue with disconnecting the battery for more than x time?

 

The Toyota FSM shows that the Radio Receiver Assembly with or without Navigation System or DCM (Telematics Transciever) has a BUB (Back-Up Battery) inside of it. The BUB might explain why your destinations were saved.

I'm reading this thread because I'm looking for guidance on how to replace the backup battery in my Entire Premium Navigation System.

My scanner is saying that the Telematics Back Up Battery in my 2015 4Runner is defective.

Any guidance in how to find, identify and replace this telematics back up battery will be greatly appreciated.

 

this works but do not turn key on when the runner battery is disconnected and do not open any doors etc...

I have to comment again ,,,, a cold air intake is a waste of $$$ on these engines..
