Couldn't find this in any of the OBD Fusion related threads.

Does anyone know if OBD Fusion Smartphone app lets me see my ECU number? or would I need Techstream?

 

Just checked and I could not find anything.

 

It doesn't. I'm pretty unimpressed with OBD fusion since I can't even read tire pressures on an '08. Lots of other stuff, but without a tablet or an Android module for the Nav screen, it's not worth a lot to me. I even paid for the OBDLink MX+ expecting to at least get tire pressures.

 

I believe the Carista dongle, along with its app reads ecu numbers. I remember doing it a long time ago.

 

Other than Techstream are there any apps/devices capable of reading the values from the OEM TPMS sensors?

 

The OBDlink app has all that in the menu, I can check later if it will work.

 

I tried using techstream yesterday but seems like my cable isn't working anymore.

Do I really have to spend over 500 British pounds for the right cable?

 

some have had good results using tactrix open port cable. I personally have the mongoose cable though.

 

OK, I just tried if I could get the tire pressures to show while connected to the car via OBDlink-MX+, and unfortunately, many of the parameters disappear once it's connected and the tire pressure is one of them

 

That's exactly what happened when I tried it. I even put a dashboard together with the tire pressures before the parameters disappeared and it made no difference. Apparently the PIDs for tire pressure are not present for certain IS F models.

 

How much did it cost you for the mongoose cable?

 

Mongoose Plus MFC3 is $495 on Amazon right now. I got one with Bluetooth (discontinued) and it was $200 more.
