Modification

Anyone who can flash MS40.1 software?

My E36 320i just had a full rebuild, a complete overhaul. It's now at 2.1L displacement, currently fitted with a 744 block and head, compression set to around 11 or close to it, I upsized the injectors and it has an open air filter, but the car is running rich. There seem to be very few people who can tune this ECU — is there anyone who can do it properly?
