The only way to stream information from the stock TCCS is being developed by 3P on here, his thread can be found here.

If your stock computer and low level modification only thing you really need is wideband and EGT. TCCS takes care of everything else pretty nicely.

The supermonitor does two simple things to read the codes. First it grounds TE which causes the ECU to go into diagnostic mode and flash the 'check engine light'. Second, it counts the pulses on the CEL and converts them to the diagnostic number.

The ECU can output the diagnostic data you seek, but it takes some real work to get at it. The reference is posted above but there is no magic cable you can buy to get to it , at least for now.
