ScoobyECU in W6 or Z4
I have finally got my hands on a ScoobyECU, well 2 actually (long story ).
Simple question (I hope), do I fit one to my W6 ECU or the Z4 that I purchased a few months ago. I've done a search, but there appear to have been conflicting views about a year ago as to whether it makes a difference

I had mine in a Z4 ECU so if you were still worried i would pick that one out of the two because then if you take it out its better as standard.

just to confirm, it makes no difference. as soon as u cut/remove the j1 connector on the main board it then reads the scoobyecu.
u would be better off fitting it to the w6 and selling on the z4 to someone who isn't as fortunate to get there hands on a scoobyecu.
cheers

Socket was soldered in yesterday and chip plugged into it
With the Z4 alone, the boost max'd at around 13 psi which is about right.
I let it run in for around 10 miles, occasionally giving a quick blast in various gears, but not getting the revs too high. Eventually just went for it and it max'd at just over 16 psi, again about right. No signs of fuel cut thankfully.
I think the chip was taken back to the base map before being sent to me, so I didnt bother re-setting the ECU. I thought it would need to learn anyway?
The drive is basically as it was, but with an extra kick I think this might be because the chip's map is based on the Z4?
Now for the rolling road

Confused now. When I bought a 'VOS-chip' ages ago it had the fuel cut set at 18psi, so, out of the range of the normal boost (16psi).
My scoobyecu has the fuel cut moved to the limit of the MAP sensor, which in my case is about 22psi I think (face-lift MAP sensor).
So you see, I thought the fuel cut was set as part of the chip programming.

I've always put this down to a tolerance issue with the map sensor circuit within the Z4 ECU being tighter the the earlier ECU.

Definately worth getting the 'facelift' MAP sensor if replacing the old one then.
