Figured i’d start my first thread by explaining what i’m gonna do. I have a 1984 Polo SP (9000 cars made) and just finished completely rebuilding the engine, gearbox, suspension and rear axle. It is equipped with a 75hp GK engine (i’ve heard it’s quite rare) and the Bosch Dignition ECU (which i figure is even rarer). Had trouble with this one as my stock unit was fried, but a new one came in clutch to make it start.
The thing is i’m currently building a new engine featuring bike carbs, schrick camshaft, ported heads, balanced bottom end and more. I plan on reaching 7500rpm with this setup. I don’t want to get rid of the original ECU, so i need a way to modify values in it. I’ve heard people working on Digifant and Motronic ECUs for 3F and PY engines, but never on the Dignition. I saw one guy in Germany who did it but he never wrote anything about it.
If anyone has ever done this or even heard about it, i’d be glad to hear from you guys.
Thanks!
Axel
