Damn... sorry about the double sig post there I know my sig is large and I try to only include it on the first reply but this forum posts it on fast replies too... and it won't let me edit those for some reason. Anyway, I was gonna take it off, AND say the following:



The sensors I meant to say the haltech comes with are the main aftermarket sensors: (water temp, TPS for S4 cars, and air temp sensor) except the MAP sensor which is purchase separately since they offer three different ones (1 bar for NA, 2 bar and 3 bar options for turbos), and it also includes the flying lead harness. You still have to provide the coils/ignitors and CAS.



For a car already equipped with EFI the install is not difficult - the standard comparison is a car alarm system or a large car stereo install.
