Here is my tweecer fresh out of the box. The tweecer is a unit that allows you to tune your engine to take advantage of upgrades and modifications, bigger cam, heads, larger displacement. For my application, I am running a WAY1 EEC with VEX 1 strategy. The EEC was from a '95 MAF pickup with and E4OD tranny. In addition to the tweecer I also did a MAF (Mass Air flow) conversion.

removed the e-brake pedal bracket so I could run the wires from the back of the tweecer.

here is the back of the EEC. It needs to be removed through the engine side of the drivers side firewall. procedure is much easier if you remove the inner plastic fender.

back of the EEC. This is the J3 port, there is a coating on the connections that needs to be cleaned off with alcohol to ensure that the tweecer works properly when connected.

tweecer R/T plugged into the J3 port with the USB cable attached The USB will allow me to connect the tweecer to my laptop and talk to it using the CalEdit software.

tweecer recommends putting duct tape around the unit to keep it from coming lose..last pic with the unit in place before I put the e-brake bracket back.

ready to tune. this is a screen shot of the scalars for my EEC.

this is the calcon software, it allows you to record in real time what your engine is doing and will monitor 16 separate functions at a time.
