Dyno Results for DINANTRONICS Stage 2

[VintageFerrari]

I own a 2014 M6 Gran Coupe with Competition Package. It already had an M Performance Exhaust and Gruppe M Cold Air Intake.

In anticipation of having a DINANTRONICS Stage 2 installed, I did did some baseline Dyno pulls on on a Dynojet.

In 5th gear, it made 544hp and 519lb-ft. Of course, it wouldn't go past 6100rpm in 5th gear due to the car's 155mph speed limiter.

In 4th gear, max HP was 548, and max torque 504.

THE STRANGE THING ABOUT THE OEM MAPPING IS THAT THE AIR-FUEL MIXTURE DOESN'T REALLY START TO RICHEN UP UNTIL ABOUT 5500RPM.

[VintageFerrari]

After driving about 110 miles with the DINANTRONICS Stage 2 Software, I retested the car (remember my car has had both the M-Performance Exhaust and Gruppe M Cold Air Intake all along).

The first graph is the 5th gear DINANTRONICS pull. Again, because of the car's speed limiter, we couldn't go much past 6100 rpm in 5th gear.

The second graph is the 5th gear DINANTRONICS pull vs the 5th gear PRE-DINANTRONICS pull.

Torque increased about 20-40lb-ft in the midrange. However, max HP at the top only nominally increased.

Dinan reminded me that all their testing is done with 93 Octane, whereas my car runs on 91. Maybe I'll fill it up with some VP 100 Unleaded and do a retest. Hopefully, my results will be closer to what the Dinan website shows.

The other potential problem affecting the top end power (according to Dinan) is that I'm running the Gruppe M Cold Air Intake. Unfortunately, Dinan's current Cold Air Intake only fits the F10 M5. Apparently, their own F06/F12/F13 M6 Cold Air Intake won't be available until the end of the year at the earliest.

[VintageFerrari]

While the max torque is higher in 4th gear with the DINANTRONIC (519 v 504), it actually shows lower max HP (548 stock vs 535 DINANTRONIC).

Looking at the Air-Fuel, it seems the Stock map in 4th gear after 5000rpm richens the mixture up more than the DINANTRONIC does.

Interesting results, I would expect much more HP. Who installed the tune did the software update take to the DT box?

Thanks man for taking the time to Dyno! finally someone showing real Dyno numbers on dinans piggy back.

There is no stage 2 available for the M6.
Only the M5 has stage 1 and 2 available.

[VintageFerrari]

Both the BMS and DINANTRONICS Stage 2 pulls were obviously done in 4th gear. The BMS dyno pull was done in someone else's NON-COMPETITION F12 M6 Coupe back in February, on the very same dyno I just used (in very similar ambient conditions).

I don't understand why my HP is virtually level in the 5000-5700rpm range (i.e. just under 500hp), and then finally starts to pick up to circa-535hp from there to redline, etc.

I wish my DINANTRONICS made 589hp ...

As a personal favor Dinan built me a Stage 2 DINANTRONICS kit due to the fact I already have both a Gruppe M Cold Air Intake and an M Performance exhaust.

Dinan built the Stage 2 kit for me, and BWM of El Cajon (here in San Diego) did the install.

TABLE OF VALUES: BMS vs DINANTRONICS Stage 2 (4th gear):

[VintageFerrari]

TABLE OF VALUES: 5th Gear -- STOCK vs DINANTRONICS:

[VintageFerrari]

Stage 1 Stage 2
HP TQ HP TQ

2500rpm +22 +44 +22 +44

3000rpm +51 +78 +51 +78

3500rpm +71 +106 +73 +109

4000rpm +69 +91 +75 +98

4500rpm +34 +40 +40 +48

5000rpm +64 +67 +75 +79

5500rpm +63 +60 +75 +72

6000rpm +58 +51 +70 +61

6500rpm +62 +50 +75 +60

Therefore, at 2500-3500rpm, HP and TQ are identical for Stage 1 and Stage 2.

At 4000rpm, Dinan HP and TQ are +6 and +7 respectively when comparing Stage 1 and Stage 2.

At 4500rpm, Dinan HP and TQ are +6 and +8 respectively when comparing Stage 1 and Stage 2.

At 5000rpm, Dinan HP and TQ are +11 and +12 respectively when comparing Stage 1 and Stage 2.

At 5500rpm, Dinan HP and TQ are +13 and +10 respectively when comparing Stage 1 and Stage 2.

At 6000rpm, Dinan HP and TQ are +12 and +10 respectively when comparing Stage 1 and Stage 2.

At 6500rpm, Dinan HP and TQ are +6 and +7 respectively when comparing Stage 1 and Stage 2.



THEREFORE, A DINANTRONICS STAGE 2 ON A COMPETITION PACKAGE CAR IS SUPPOSED TO HAVE A 22-75 HP INCREASE, COUPLED WITH A 44-109 LB-FT TORQUE GAIN, ACROSS THE BOARD.

THE DINAN EXHAUST + DINAN COLD AIR INTAKE, WHEN COMBINED WITH THE REVISED STAGE 2 TUNE, ONLY IMPACTS/INCREASES THE STAGE 1 HP AND TQ NUMBERS BY 6-12 AT ANY GIVEN RPM!

IN FACT, DINAN'S WEBSITE CLAIMS ONLY AN 8 HP GAIN WITH THE EXHAUST ALONE (AND 13 HP AND 7 LB-FT FOR THE COLD AIR INTAKE WHEN COMBINED WITH THE DINAN EXHAUST AND STAGE 2 SOFTWARE).

Can't say I understand all the workings. But is the net net the tune adds little or no value.

I would make sure the dealer uploaded the software appropriately . There is no way it is working correctly . And with the new VIN system there is no way you could have had stage 2 software uploaded to an M6 period . There are a couple threads showing 60 whp gains with stage 1 and my performance numbers def go along with that . Heck one guy with a CP made 570 whp on a mustang dyno .

When you program a Dtronic computer you have to enter the vehicles information first before you can select a tune.
If they release a stage 2 software then ALL Dinan dealers can now program stage 2 software, not just for just for 1 vehicle.
You should have your software re-checked and make sure that the tune was properly loaded.
You should be making more gains then what you are experiencing regardless of stage 1 or 2
Or did you purchase a pre-programmed module from Dinan ? That would prob be the only way.
But if they released it for you then it would only make sense they would for everyone else.
There are lots of S63T's with the same setup as you.
Either way, I look forward to your feedback

[Spinny02]

Thanks for taking the time to share your data.

I am sure Dinan will work with you to get the DT correct. Looking forward to the end result.

Yes.

I'm certain something isn't right , both you're runs are within the repeatability margin of dyno runs . You definitely need to get the module looked at .

[VintageFerrari]

I'm told that something like 20 degrees too hot intake temps can cause the system to pull timing (and therefore power). When doing all pre- and post-DINANTRONICS pulls, the dyno shop only used a fan in front of the radiator.

How important/critical is it to also have fans in front of each of the intercoolers?

Sure that's a shitty dyno set up , but it wouldn't cause you to have no gains . Even stage 1 is a HUGE gain . My m6 CP does 60-130 mph in 7.4 sec and traps 130 with it .

[VintageFerrari]

I'm currently at a different dyno shop, about to get my car dyno'd. This time, there'll be fans in front of both intercoolers (in addition to the radiator).

Stay tuned ...

I would make sure you actually had the tune loaded on the ECU first .
