Try it and see if makes any difference. Locking out the distributor removes a variable from the setup which makes things less complicated but it might make it harder to start.

I'm tuning some EFI cars now that have more timing at idle than at WOT. So they don't have an advance curve, more like a retard curve. But EFI has built in start retard so they always have 15 degrees when cranking.
