I have an ek4 turbo with a greddy emanage tuned by an authorized tuner. I was planing to make an obd1 conversion. but in my country no one knows how to chip or use crome uberdata etc...
My idea is to buy a conversion harness and a chipped p28 ecu with a specific basemap and tuned with the emanage. Its this possible having 2 ecus and a piggy???
thanks

 

Seems like a complete waste of time to bother converting to OBD1 and then using the Emanglage still.

If nobody can tune anything but the Emanglage out there, no sense changing it..
