Hi chaps

Does anyone know of Mac/PC software to interface with
with a Bosch MP9 ECU that enable you to modify the Fuel map?

I have tossed the old K-jetronic and fitted MP9 with the hope of
increased performance and economy, but the dyno readings show
the standard software being too lean at part throttle and rich at idle
and WOT.

I am not interested in fitting aftermarket "ECU Bridges" but rather
want to map the ECU software correctly.

Can anyone suggest a remedy?
