No, I am talking about the after cat sensors. They are the ones that report the mixture of the exhaust. The primaries do not.

 

Will any of the relatively inexpensive ODBII dataloggers report on the knock sensor or manifold pressure? If the knock sensor is being triggered what changes will you see in the A/F, boost, and timing?

 

The computer will immediately richen the mixture and retard the timing.

 

Most of the data loggers DO NOT report knock count. You need something more professional than that like a PSTII/III. They will do manifold pressure and timing. Most will not do fuel trim either. If you watch the AFRs and the timing you would know if knock control was activated.

 

Yes... I have the same one and it does its job well. Dan's a great guy to deal with and is very helpful.

 

I have not been able to get the harrison unit to read manifold pressure. It does fuel trim very well.

Maybe someone will get the VAG-COM to work on a Porsche.

 

Andrew its time you dump that thing and get into a Porsche!

Your car looks great but if you want real performance with great turbo options its time to make the leap.

Notice how cheap the 996's are?

 

No kidding, would be able to if I still had my old job, but I quit to start my own company, which hopefully yields some better results .

I'm only 24, I've got some time to get into a Porsche
