OK ok I remember now, I had a 91 GLI 16V, The computer was one unit, Not a knock box and ECU. and If I remember correctly, the harness went from the engine, inside the car to the fuse/relay box to the trunk, then back up under the dash.....
Has wicked electric recaros, power windows, and was the first to have a real diagnostic port by the shifter....
But I took that engine out and stuck it in a 87 16V scirocco w/50mm intake & header.. I did port a 1.8 16V head for it, cause the head gasket was leaking...
The source of info unless its from ETKA, my memory or a Bentley, I wouldn't trust it.....
OK now its a legal issue, If you up date, you have to do it all correct? Keep in mind the used that system for 3 or 4 years... then obdI save our lives diagnostically...
I am trying to forget about digifant, that was the biggest pile of crap ever made! I have 1 ECU left & I want $300... They always go bad..
