2007 Civic AC Problem MICU Replacement

The compressor has been replaced as has the pressure switch and under hood fuse box. All fuses and relays are good but the Civic diagnostics manual points to a bad MICU. Problem is this is something that requires an HDS to re-flash the MICU to the ignition keys. I can replace the MICU but from what I understand the car won't start until the re-flash is done. Is my understanding correct or is there a way I can replace the MICU and then get the re-flash done later or is there another alternative. My guess is Honda will charge max for the part plus labor and I am guessing this will cost $500+.

Only reflashing micu thru HDS is possible. Try tacho swap for someone to test because if tacho isn't ok compressor won't kick is. Hadnit on mine
