[momax_powers]

looking for recommendations on tuning...which route i should take.
i dont know too much about it but would like some input as to whose tuning provides the best results for a 540.......markD? dinan software?

if your 540 is 1997 and is 6spd than a Mark D tune will make the most difference for the money. If you car is 1998+ than a tune doesn't really do much. 1997 540's were made in the M-factory and use larger intake manifolds from factory, later on 2000+ DINAN E39's used 1997 intake manifolds.

actually the MarkD tune works really well with 98 E39's(I had one with MarkD tune), it's the 99+ models that doesn't do much, also it works really well with automatics, another member here has a 97 540, he originally had the Dinan Stage 3 software & auto tranny software, he said it was shit, he than got a MarkD tune & said that MarkD tune was way better than the Dinan software & tranny software that Dinan offers.

Yes

MarkD has software that works great in the all the 540's, right from 1997 to 2003 . If any of you have a later 540 and were not happy, just contact him for a fix. What probably happened is that your car was flashed via the OBD-2 port instead of the round ADS connector. This connector is even in some 2000 540's.

What about dyno tune in accordance to the mods? AA used to offer remote dyno tuning, so does AutoLogic but I can't find anyone with AutoLogic in Toronto that will do the tune.
