just downloaded the free bluedriver app for my iphone4s,looks pretty cool and displays coolant temp gauge,went on e-bay to buy a obd2 wifi dongle and i see the elm327 in various forms but when i plug in compatability for 97 D1 it says no,will this work? and display coolant temp [made the mistake of buying an can ms309 code reader and it doesn't display temp and don't want to make same mistake twice!]

 

while this response is useless to you.... your iphone 4S can still function... dam!

 

hey,i'm using the trailing edge of technology like my D1! but will the elm327 work?

 

I don't believe iphone 4 will be compatible with the Bluetooth dongles. You will need to purchase a wifi dongle.

Amazon has them.

 

my iphone4 has wifi and the dongle says for both or am i missing something?i intend to use with wifi not bluetooth, the elm 327 says for wifi ios,but i do use this phone on bluetooth in my car with new stereo,will it work with that?

 

Not sure if you phone will be able to feed the stereo via bluetooth and the read the dongle via wifi simultaneously.

Each dongle is a little different as well. Not sure about yours.

I use an app called "OBD Fusion" which is well worth the $10 from the Apple app store

Between the dongle and the app you're talking about $30. It will save you hundreds in parts, time, and frustration.

 

thanks for response,i think since i have iphone set up it should work,just wasn't sure if the elm327 product would display temp in degree's so if anyone has used one please let me know

 

Yes. ELM327 (wifi) + OBD Fusion app is what I use.

 

thanks,waiting to hear if it works with old iphone4s if not i think the foseal product will,even though they look identical,appreciate imput

 

just got elm327 wifi obd2 and attached,iphone picked up connection and green check is on,using bluedriver app ,when I open ect gauge it shows 190deg which is my t-stat temp,doesn't really change and it does say Bluetooth not connected,in settings I do have the car kit connected and other devices doesn't pick up elm,questions are why doesn't the wifi connection seem to show live data and shouldn't that be all I need,appreciate any imput
