The new techedge kit uses the Bosch sensor which is not scarce like the NTK sensor has become. The sensor for this kit is 100 bones. Cheaper than the NTK sensor in its hayday.



IMO a wideband is a much better tool than an EGT. Have you seen V2.0 from techedge? We are talking A/F logging, RPM logging, temp logging? How does that compare to the EGTs peak hold?



Check out the specs. If you can build the DIY kit you will be miles a head. I had hardly no electroics experience but I was able to build a v1.0 with no major problems. It was a thrill to be able to build the unit/display.



Give techedge a look man. http://wbo2.com/
