ECU mapping and gauge programs?
 

hi little bit new to the whole electronics subject of my car but i was wondering if anyone could point me in the right direction for a good program for mapping and to bring up guages on my computer and where to find a good wireing harness from the ECU to my laptop. Any suggestions or anything at all will help thankyou.

There isn't a way to read data from a stock ecu...well there is but no one makes a kit (cable and software) to do it.

thanks what are some of the advantages to upgrading my ecu?? and what ones are the best for the job?
