The 400 is not an ecu upgrade; it has a different engine - a newer version of the B58 knp'm sure I read that the wn as the “B58 01”, which has a higher output before you start tuning it. The tuning for 402bhp was done by BMW.

My understanding was as follows, we maybe at cross purposes here :-


'BMW approved the use of its engine and permitted Morgan to conduct its own throttle and powertrain tuning for the Supersport 400, provided Morgan utilized their official calibration partner, FEV''

Isn't that what I said, doesn't that not involve ECU upgrades/programming in conjunction with an approved BMW tuning partner. I didn't mention the engine type.......the point being that BMW still kept control over the process...... cheers.
