After revisiting, I finally got my generic ELM 327 bluetooth OBD scan tool to work with my 2004 corolla sportivo!!

turned out the initial "handshake" needed to communicate with the ECU is quite particular, so when running the TORQUE application on galaxy S4, I set up a vehicle profile for the sportivo, then scroll all the way down to the "custom conflagration string" field an input the following:

nooooooooooo :'(

Excellent discovery kenshin

Now, is there a bluetooth version of that tool that would work with TORQUE on an android?

Ok, so I realise this is an old thread but..

Let's say I only wanted around the 30-50kW mark more than stock. What would be the most cost-effective way to achieve this? (let's define this as $/kW). Can this be done without a turbo?

BUMP... joined purely for this topic. I have a ELM327 myself that I bought a few months ago, but sadly it has not worked on a single car I owned so far. Works on most of my friends cars, using the TORQUE app for android on my S3 and it's quite good.

Also just bought a 2004 sportivo in mint condition and I'm likely to change the head unit sometime soon (mostly for satnav and bluetooth calls/music). So just thought it'd be awesome if I could somehow hack the OBD to work on the sportivo.. then interface it with the head unit of the car so I can have all the dials right there I'm an electronics apprentice, so any soldering/rewiring of the OBD will be a piece of cake..
