Subject: [s-cars] S200 20V  Rocks

Hi  !

Yesterday the A200 20V was ready to rock with
RS2 ECU and factory SW. I have now driven first
180miles and with :)
- no problems yet

If you want direct ignition to A200 20v, buy urS4 - urS6...
-it is much easier to do so than doing the
cable loom conversions to A200  I did.

I´ll let you know how the 3B DI engine combo performs. One
thing is sure that the engine revving sound is
different in 3B Direct ignition
than in AAN based vehicles.

I wondered why and quessworked that the reason
might be the MUCH heavier flywheel and crank damper
in AAN ???

I think that the much lighter 3B
is much eager or hungrier for revs.  It is like a racing
flywheel to S4.  - So it seams and the car
is asking for more REV punishment. More to come later when
the engine has been driven in next 1000-1500 miles...
