Just a quick question    
 
Which motronic ECU type works with a later type redtop from an astra gsi? i had a feeling it was an FP rather then GK etc from calibras? will a GK ecu work with this engine or do i need the exact one?

any will work, as long as it's the same style ignition system.. 
 
ie a dissy engine, using a ecu of a dispac engine wont work  etc etc
