hello all,
Anyone know what would be a good ignition dwell time for the rover V8 4.6 engine using the GEMS coil packs.
My ECU settings are 3.52ms, just wondering if this is too low?
cheers

That sounds spot on to me, when I was having issues with mine we tried some different values but that is what GEMS coil packs seem happy with

cheers, it's good to know that this setting is ok.
Changed my spark plug gaps to 1mm from 0.9mm, as per the rave manual.
Thanks
Scott

Figure I found for plug gaps with EDIS was 35 thou. So approx 0.9mm.

sure ive had 0.90mm in mine since the start, just thought the spark might have been a little weak at idle, so I set them to 1.0mm.
Not much difference I can tell, need to tune it better first I think.
cheers
