Software
1996-1999 E36 318 Z3 DASC Software
Finally there is
software specifically made for the 1996-1999 BMW M44 engine running a
positive displacement Eaton M62 Supercharger. The building block of all
stages is the reprogrammed DME. Hundreds of hours have been spent
studying, figuring out, and reprogramming the computer. The result:
excellent drivability, no check engine lights, and increased power. All
stages have the following features in common:
|
- Increased engine rev limiter to 6800rpm
- Removed vehicle speed limiter
- No Check Engine light if DISA valve is removed
- Remapped fuel and spark maps
- Lambda control and adaption remain functional
- Elimination of surging during light boost conditions
- Revised HFM error table to eliminate faults due to HFM pegging
|
Below is a description of the various stages offered:
|
Stage1:
Stage 1 consists of
reprogramming the customer's DME. Power peaks were increased by 5.9ft-lbs
and 5.4hp at the rear wheels on our test car, and as much as 12ft-lbs of
torque was gained at the rear wheels in the midrange. Gains are achieved
by modifying the spark advance and fuel mixtures to better suit the boost
pressure that the engine encounters. This program relies on the rising
rate fuel pressure regulator to be installed and functioning
properly.

|
Stage2:
Stage2
further improves power and reliability by eliminating the rising rate fuel
pressure regulator and replacing the factory fuel injectors with larger units.
Power gains of 6.9ft-lbs and 12.1hp at the rear wheels vs. stock programming
have been seen. The DME is entirely recalibrated to work seamlessly with the
larger injectors. Included with the kit are new higher flowing fuel injectors,
custom machined fuel injector mounting adapters, and new o-rings.

Price: $799 plus shipping and handling
|
Stage3:
Stage3 ups the ante further than Stage2 by replacing the stock
mass air meter with a larger unit and an ITG air filter. The larger meter
uncorks the system and allows freer breathing. A power gain of 7.5ft-lbs and
17.5hp at the rear wheels vs. stock programming has been seen. Again, the DME
has been custom programmed to work with the larger injectors and larger mass air
meter (larger meter not included; inquire for details). If you are looking for ultimate power from your system then this is the
kit for you.
