As I understand there are only two examiners that can do an MEIR renewal in the USA - Mr Paul Thompson and Mr Stephen Fisher - both located in FL. I have the contact details for the former, if you're interested. I was told by a flight school in Cali that the examiner in Arizona (Name escapes me, but he does some work out of Phoenix and Cali) cannot do MEIR renewals - never spoke to the guy directly though.
I have a friend who did his IR on the DA42 but renewed in FL on a BE76 - he told me the transition from glass to the six pack wasn't as difficult as he thought, so don't be put off by it.
Depending on how long it's been since it expired (if at all) you will need a certificate/letter from an approved training organisation stating what retraining will be required, if any, as per EASA recommendations.
