its just days from being installed (M56H from a salvaged S70 n/a 1998,average milage). After 3 weeks of hard work (arms are still paining). Probably my superman hearing working overtime, but is it normal to hear a sand mixing type sound (not loud) heard with windows down and only at low rpm / load. Its like my 740t when i drove it without the gear lever sound proofing.

Also getting the major electrical warning light. whats the procedure for telling the ECU its a manual.

My M56 is a little bit noisier than my automatics so I wouldn't worry about it.

As far as the ECU goes the only thing you can do is replace it with an ECU that came out of a manual car. Make sure the emissions codes match up with your car. Is the car you installed the M56 in a turbo or NA?
