Hi Andrew,

What?  You were in New England, and a list member and didn’t stop in to see me?  Hey, VT is a beautiful place! 

I don’t find the web sites all that easy to use. 

So, What does this engine management consist of? 

Example what does it use for a AFM? Does it use a cam sensor and pull sensor like the GW version?  Does it have on plug coil like the GW and come with a ECU? 

Does it still use some old parts like the Idle Air control valve?

Does it have the ability to be upgraded or fixed with a computer upgrade? 

Can you connect a Scan gauge.? 

Is it a learning system? 

So very interesting. 

I just read something from another list I never thought I’d see.  A person that removed a Jetta engine that was tired and replaced it with a GW 2.3 but with this engine management.  Also just concluded a nice long trip.

Thanks for the info and share more if you can.
