Yes, that is second hand for the D Sport ECU. So what did your boost end up being in the end? Are you using a boost gauge?
Im running standard boost and don't have a boost gauge anymore. The standard ECU retards the timing above 4K to keep the power below the 47kw limit so most of the gains were from correcting the timing. I'd guess the D-sport does that too. There was some gains by leaning out the mixture a bit too as with most factory turbo cars the run too rich on boost.
I see. Is that why it pulls well up to around those revs and then it just seems to be very slow in the mid to top end range? Mine pulls really well from the start up to say 5K tops then it just doesn't pull very much after that. I read the boost max is around 15psi for the standard Copen and anything much more than that you will get the fuel cut. Also the weakest part is the Actuator more so than the Turbo.
