A quick update...
I need to pull my finger out now.
I spoke to qpeng (the VW guys who I bought the ECU from.) They are going to put a more accurate map on the car so it runs a bit better and driveable.
So first step on the way. Sent ECU to have a diagnostic check to see what's going on. And a better map loaded.
In the mean time, I need to install bigger injectors, finish cloolant pipes for charge cooler and vaccum pipes. Before ECU comes back.
Install ECU and retest car. Call qpeng who will then come and visit me at my house (what a service!) to do a more accurate road map. Then rolling road for final part that day.
Looking at starting the tax for the car beginning of Feb.
Maybe first airfield day March.
