What made you give up on the N52? ECU issues?

Since you decided on the S54, what part of the S54 harness did you have to mod if at all? Is it the E46 M3 ECU, or are you using something aftermarket?

I'm just really curious how you got the S54 in there. Did you have to mod the subframe or firewall?
