Hello Ron,
thank you for your quick response... For the moment I have only one problem but its not a mechanical engine-problem I think:
The engine sounds good

and revs quickly up

but only slowly down

It is the only thing, which doesn´t fit to a sportscar.
It´s not a drama, but it´s even not perfect, to the car and not for me....
I think you know what I mean:
acceleration goes like this: 1000,2000,3000,4000,5000,6000
feet from the pedal for switching the gear, or cruising:
6000,5700,5400,5000,4500,4000 in the same timeline as upwords....
Is it caused by the ECU for bringing more fuel in the engine for cooling down? Or is it more a matter of a to heavy flightwheel built to comfort the grandmas in the states?
Do you know what I mean?
I stated in the further post only, that these engines are AFAIK NOT one engine cause they must have changed something. The T8D should have been better for coming up from higher revs, so is it told to me...
When you are sure, that one can change the parts fine? But what have they done for generating the power of 100kw? Only remapping the Ecu?
THX for your patience in advance
Don
