I just drove mine after getting my bugs worked out. I isolated my fuel pump realy with a another relay to isolate any back feed and it has fixed it. I used the wiring chart posted here with the updates. No issues with drive ability--acts natural. For those who are still having issues with fuel pump and O2--use the e30 pin 13 to trigger relay-and positive 12v ignition on to relay to power e36 pin 13. I will get th exact pins in the morning as far as 30--85--86--87 and what goes where.

Okay, the fuel pump problem is easy. AKG have got the pins wrong on their chart.

They have got E30 pin 6 going to E36 pin 13. You should have E30 pin 13 going to E36 pin 13.

E36 pin 13 is a 12v signal coming from the E36 fuel pump relay. This passes through pin 13, and needs to go to E30 fuse 11, and then off down to the pump.

AKG have got a 12v signal coming from the E36 fuel pump relay and connecting to E30 pin 6. This is a 12v signal from fuse 9 that would normally drive the O2 sensor relay. They basically have 12v connecting to 12v coming the other way.

I also noticed they don't have any connection for the Rev counter. You need to have E30 pin 9 connected to E36 pin 20.

You also need to connect E30 pin 14 to E36 pin 14. This is the road speed signal into the DME. Without this signal, you will not reach maximum RPM.

If you want the Unloader relay circuit to operate correctly, you also need to connect E30 pin 15 to E36 pin 15.

Unfortunately, I can't see any of the above connections stopping it from firing (assuming you give the fuel pump some power).

It's got to be worth connecting as above, and have another go though.
