Hi all,
Got the new ECU, which seems to have a longer power curve but does not retard the timing to prevent some seriuos detonation all the way through. I have decided to go back to the standard ECU to preserve the engine. This occurs at 1.1 bar boost where the Viggen should in fact run at 1.4 bar. Iam a little dissapointed Saab SA will not be requesting another ECU as it is too expensive. They should have retarded the timing about 5 degrees throuhout the rev range during the Turbo cycle. I trust that they will be considering a refund option. Goodbye Viggen.
