I never seemed to get the expected performance from my SC. I run MS2 with wideband lambda and I believe the are no issues with fuel mapping. About 12.6 AFR at WOT.

Ignition is dual EDIS and VR sensor also run by the MS ECU.

I now have dual ignition and a dual EDIS ignition, but no significant difference from when it was single spark EDIS, it is still a a dog

Performance is just not comparable to a friends stock 3.0 SC. His car is stock. Both of us have the same exhaust with SSIs and Dansk Sport muffler. My car is not at all rev happy like his. Every time I am in his car I wonder how can it be this is just a 3 liter with the rev happy pulling like a locomotive character, while in my car I always think how disappointing it feels. Engine note from exhaust is different too, with his the basso profundo from his car and mine sounding a bit strangled and tinny. And I have the 70 mm dansk sport

Both of run stock cams and same engine code (1980 US cars). His engine seems to be completely stock, based on invoices from previous owner

I have decided now I will get to the bottom of this;

As I can see it must be either my ignition is letting me down or cam timing. I set my cams at 1.55 mm, don’t know about his. He runs stock distributor and CDI, I have EDIS

Is it possible that my ignition is letting me down ? I have decided to do another cam timing and see if retarding the cams slightly to 1.1 mm might make the difference. If not I am lost


Any advice ?
