Need help diagnosing Nistune ECU in limp mode

[z1 zonly]

I bought Nistune and had it installed in my ECU. Put it in the car and it runs in limp home mode. I've checked the install and it looks like it was done well. I switched back to a stock ECU and it runs perfectly and connects to Consult.

The way I see it, there are two possibilities:
-A hardware problem with the ECU. This ECU was running the car well before Nistune was installed, and since the install was professional, I don't feel like this is the issue.
-A problem with the base image that was loaded onto the Nistune board.

The ECU code is A18-A21 P60, and the seller of the Nistune board says he used that to get my base image. I have a copy of the .bin file that should be loaded as my base image--can email it. Can someone give me some guidance as to what I need to do here?

My SR20 ecu did the same thing, most likely an error with the install. My case was the previous owner installed the eprom backward.

Matt at Nistune has been incredibly helpful in diagnosing it. It looks like the seller forgot to program the board with a base map before sending it to me. Durr. Anyway, a my board is on the way to Australia and a new one is coming back--we'll see if that does it!
