Several months ago EFILive released an industry first solution for speed density tuning on vehicles using the E38 or E67 ECM's. Since that time there has been many successful boosted engine builds proving just how well these two ECM's can be tuned in Speed Density mode (naturally aspirated or forced induction) running the standard factory ECM operating systems.

For those not familiar with the E38/E67, these ECM's have no VE Table, instead, the VE numbers are calculated on the fly from a set of VE coefficients, EFILive displays a 'Virtual VE Table' to allow tuners to alter VE numbers as though there was a real VE table, the software then converts the 'Virtual VE Table' in to VE coefficients.

Does it work? yes, very well. Above are some vehicle examples that have been tuned without a MAF, running 2bar forced induction and 'no' customised ECM operating system.

The 'Virtual VE Table' is a free software feature available for all 50+ E38 and E67 operating systems supported by EFILive.
