IF you were to get the zt2 and DashDaq you could datalog, read & clear codes and display your engine parameters in metric. It would be a great addition for your car with your planned mods. Just getting the DashDaq will plug into the OBDII port and read & clear codes, data log the ODBII outputs and let you display the parameters of your choice. Without the zt2 you will still have the data speed limitations that Zahanma mentioned...
