M5 should always get priority on the dyno

I must not wish my life away........

Roll on the 1st February

Who said it isn't three M5's, two M3's, and one M2C going on the dyno between now and next friday?

Torque is what tends to break engines/bend rods. We're taking an approach that deliberately limits TQ to at or under 600 ftlbs. HP is only a measure of how FAST the work is occurring.

Keep in mind -- we drive/test our dev' vehicles HARD. These are not glory numbers just for publishing results. We test relentlessly on the street. With a well maintained car, we haven't experienced any issues so far.

We actually have a track day Monday where we'll really put this M5, other OFP tuned BMW F-Series cars, and our Ferrari 458, to work! Real world results.

1. We don't manipulate the fuel pressure targets. Haven't found a need to do so. Fuel pump is only working as hard as BMW intended from the factory.

2. We run a max of ~20.5PSI at redline. In the mid-range we're only at ~13.5PSI. We have not yet found a need to go higher than ~21 psi max.

Note: The stock turbos will generate more boost if you desire -- understanding how the tables work, and making the correct changes to achieve that goal is what can be hard. We've invested 100's of dyno hours in understanding exactly how this ECU works; as you may have noticed.



Going higher than ~15 PSI boost in the mid-range will most likely contribute to accelerated engine wear = tons of TQ --- we've tested just north and south of 700ftlbs in our dev' car.

3. Catless DP just aren't necessary in our testing. This day in age, it just isn't a viable solution because in our testing no power restriction exists from the OEM CATs.

Without the CATs, there'd maybe be improved spool up, but honestly -- WHY? We can generate over 600 ftlbs of TQ @ 2.5K RPM ... Again; anything more could attribute to accelerated engine fatigue, and only results in excess wheel spin =

NOTE: We are working to MAINTAIN street legal compliance, and have submitted our application with CARB/EPA which has the potential to make the OFT fully smog compliant.

4. If you look at the top right of the graph, you'll notice we use the same correction every other vendor has opt'd to use. STD at smoothing value of 5.

5. We'll be testing as soon as this rain clears up! We won't speculate on these numbers. --- We'll post actual results.

I'm doing a catless downpipe because of the sound and mild performance gains...how does this tune do with catless downpipes? Is there a CEL delete incorporated in all of the maps?
