S.E.C.S. Engine Data Monitor
 

Iv already got Defi Oil Temp, Oil Pressure, And Boost, is it worth getting one of these units Secs?
Only read alittle bit but all it does is Plug under the wheel i take it but can ECU resets be done with this??

A very useful device giving instant readouts of all the info. you will need to monitor what's going on.
Having seperate gauges for oil press/temp and boost (as I have) is a good idea and set up the 5 pages on the secs unit with the combinations of other info. you want. The unit will read faults and give you the code (sheet of codes and their meaning supplied) It will also give you max. boost, revs, speed, engine temp, readouts (re-settable) You can also do an ECU re-set at the touch of a button.

Yup very good bit of kit, i have this along with the defi's in mine, also reads for injector duty and ignition timing, air and fuel etc ;)

Ah cool, i want it more for the fault codes and ECU resets
