Please do not quote prices of my products and then add + + behind it. There is no +. The system includes the basic programming and the software.
Also you are grossly oversimplifying this process. Unless you have done this project then you are leading someone down a path that is very time consuming and difficult to get to work properly on conjecture.
If someone wants to do this then it can be done but modifying the signal is going to be hard unless you have something that is mathematically near perfection. And you have to have both rear speed sensors or signals for sure. And the signal needs to be acceptable without fault.
Also as I am sure I have said. and everyone seems to ignore on these projects is what are you going to do when you need a new key or Ecu or any DAS component. Nothing you are going to go buy another donor car to replace them all. Or spend thousands of dollars to do what I did and buy key programming equipment. But that still does not get you around the ecu and other DAS components. If I could have bought an ecu for a few thousand or 5 thousand to run my engine in the aftermarket I would have and it would have been cheaper.
