Z4 ECU and Engine Check Light
Just put a Z4 ECU in me car, did have a chip in which i removed and reconnected J1. But the engine check lights on now. Any ideas why, does this mean its damaged?
All i have done so far is started it, havent driven it yet. Does it need to run for x miles for it to sort itself out?

Finished panicing now...lol
The black wire was an earth wire, so popped that on and no more check light. Im assuming the black box is a delimiter.
Must say it feels much stronger with the z4

Code 45 is the map sensor so I expect that little black box is a fuel cut defender wired in to the map sensor on the ECU.
If that orange wire goes into the 4th connection from the right, and the blue wire goes to the same colour wire that 'was' in that position. Then that's the map sensor input bypassed.
Therefore you should assume that someone has been running close to or above the standard fuel cut limit of 1 bar (approx).

You can use an electronic boost controller or a mechanical boost controller (Dawes Valve or Bleed Valve) to increase the boost.
The ECU has a fuel-cut/overboost limit which is set to around 1 bar in the early ECU.
If you increase the boost by the method above you will be getting close to or over the standard fuel cut limit. Therefore the little black box you have is fitted to fool the ECU so that this higher level of boost can be run.
This increases the performance but doesn't adjust the fuelling or timing, so can be quite risky.

I have a chip thats meant to boost upto 1.1 bar but the car only goes upto one. Im assuming this black gizmo maybe stopping it or a manual boost controller??
Can i just chop the wires to the black gizmo off and tape them up?
Whats a MBC look like so i can see if the car has one?
