Closed loop on ECU without full remap?

[feef]

I've got my 17% reduction pulley here for my supercharger, and I'm itching to fit it, but don't have a dyno date booked yet to get a full remap. I've got an Emerald ECU, standalone, running a closed loop map using the wide-band O2 sensor, and have the option of an 'adaptive' map which will write adjustments to the map based on the O2 sensor readings. The reduction pulley should increase the boost pressure by maybe 7-10psi (unless my calculations are way off)

I was contemplating installing the reduction pulley tomorrow (and the chaps from Emerald won't be about till Monday) but am not 100% if a closed loop/adaptive map would be okay until I can get it mapped properly, or would it be more sensible to wait till I have a remap booked and run it at the higher boost pressure for as short a time as possible before the remap (e.g. just the drive over there). Don't want to end up with it running stupidly lean and wrecking the engine before I have had time to get it mapped.

Thoughts?

Closed loop on most budget standalones isn't fast enough to fill in the fuelling gap an extra 7-10psi will create. You need to get the base map done first. You might need bigger injectors as well, plus some ignition pull. Best to wait until Dave Walker can remap it properly.

It's been mapped at the current boost already, so not sure how much different the basemap might be, but I know the injectors are bid enough (so big it was tricky to get it to idle properly).

but the point about the closed loop responding quick enough, that's a good one. I wonder if the 'adaptive' mode might help that tho, where it's continually writing incremental changes to the map as it goes.

From the sounds of it, I'll leave the pulley off until I have a remap booked, and then fit it just before a very gentle cruise to the dyno center
