Re: squadra for 75
On a Motronic it works well; Robert G has one on his 75V6.
If you run LJettronic, you can fiddle a bit with the fuel settings (to support fast-road cams) which works OK, but is not as refined.
Important thing to take into account: a 75 has 2 fly wheels. Despite the chip, the engine will not rev as you might like it. Reducing the weight of the fly wheels helps more in that aspect. Also this will make shifting faster/nicer.
If you do not drive with rear passengers (especially behind the driver) you can attach the shifting to go through the car (instead of the current construction with levers) which makes it shift even better.
