SuperFlow Dyno using Eddy-Current method, where the Dyno wheel is loaded so you get a more true street number. We strapped it down, measured the tire diameter and put in 4K lbs for the weight of the car. Then put car in "Roller Test" mode, and all pulls were made in 5th gear. Note it was about 105F outside but not sure exactly what it was inside the shop with coolers running and 3 fans in front of the car. Cooled the car down to 120 IAT's for all runs except the Valet Mode MAP8. Fuel was Shell 91Oct


Here is the HP/TQ for the runs:
Stock in C mode = 335/410 - seems low
Stock in Race = 330/436
High Flow Air Filters Race Mode = 335/364 - not sure how I lost TQ
Map1 Race Mode = 419/453
Map 8 Valet in Race Mode=285/391
Map 7 +5psi =436/? (getting the graph again since it did not print)
Map 7 +6si = 438/523

Logs attached and will scan in the Dyno graphs later

Thanks. It’s a shame that more often than not, something looks whacky at a dyno. You’re right that both stock having 335 hp is low and that the 364 tq with the air filters is really weird and highly suspect.

anything more on the codes/rough running today?

thanks again for doing the testing. Looks like you skipped doing map 2, correct?

Delta sounds good for a load dyno. Remember numbers will vary dramatically based on the machine and operating parameters. Only the dynojet brand is relatively consistent. I see you emailed the logs in, we'll check those out tomorrow for you.

Vader-C63sE1

Yeah looking at the Delta I think things lined up, my plan will be to find a shop with a Dyno jet in the fall when things cool off, I’ve only ever used DJ’s so this load dyno as a new game. On the street the thing is insane, I added 3 gal of E85 and topped off with 91 and holy s**t it’s spinning the 305’s even with the 1st and 2nd boost reduction 😎 but it’s totally controllable

Are you using WMI with 3 gal of E85 on Map 7? What Map are you running? I got rear ended last Tuesday right after putting in E30 (4 Gal of E85 with 93 octane top off), so my car is unfortunately at the shop for another month. I had a difficult time finding a shop with a Dynojet in my area. Most use Mustang. I was planing on Dyno-ing. I want to invest in WMI, but I am not sure if I should take the leap yet. Did you observe any codes or issues with the WMI install? Thanks!

Vader-C63sE1

I did try using E85 with all MAP's including 7, but my car did NOT like the E85 even at 3 Gallons with 91 top off. I was getting all kinds of misfire and vac leak codes and limp mode, so I ran that tank out on the freeway. Then I filled up with 100oct race fuel and most all my issues went away. Now I am about maxed out on the fuel trims on MAP6 /100oct so will probably stick with my WMI using 91oct fuel on MAP7 with Boost Add or 5 or 6 and try 7 at some point.

The Install of the WMI is time consuming but if you take your time it can be installed very stealth and even keep the OEM cabin air filter box.

I still have not found a shop that will allow me to "rent" their Dyno-Jet most won't allow that unless they are tuning you or doing other work.

Sorry to hear about your accident, that must be very frustrating! Let me know how you do on the E85, 4 gallons is kind of a lot, most go with 3 but my car did not care for it!

AMGMessiah

Thanks for the prompt feedback. Yeah, 4 gals of E85 is right at E35 topped off with 93 octane. I did not get a chance to fully test the car on the mixture. The additional 2 octane might make a difference on how the car responds. We'll see.

Anyone hear any updates on the intake>

BMS

Soon!! Production always takes a little longer than we'd like on these things.

Why doesn't BMS or another tuner (besides Dinan) offer a warranty for an extra $1,500-2,000? I really want to get a JB4 for my girl friends M340 and my C63s when it gets here. But it's so hard to justify losing the warranty. I feel like it would be really profitable for a 3rd party company or tuner to offer this.

cij911

BMS - any plans to release the JB4 & BCM for the w212 e63 / e63s platform??? please

MuffinFlavored

of these columns

here are the ones that never change/don't work:



have any updates been done to the m177 jb4 firmware to log any of these missing fields?

imedina86

Any more user feedback on experience with the jb4? Went on 54tech and noticed c63amg people having issues, moisture getting into jb4 casing... i have a jb4 on my pure stage 2 335, with mhd backend flash... i had some good and bad experience with the jb4 on the 335, jb4 case melted onto the board, the connections sometimes suck, even if you install everything properly things might not work properly and you have to sodder connection (power wire)... was hoping to hear more positive feedback from c63s people before I buy a jb4 but can't find much

MuffinFlavored

lol
they told me my jb4 got moisture in the case when my f10 m5 engine grenaded itself

would you trust people who can’t make a watertight air case for $2 to work the complex electronics of spoofing signals to german engine components?

imedina86

years back I was about to buy a jb4 for my e70 x5m then people were having issues with it so i waited for issues to be worked out before I purchased one BUT they decided to just stop selling it to e70 x5m's... instead of fixing the issues they just stop selling it ... i guess I should spend more and get a dme tune

MuffinFlavored

mo at dme tuning is world class, he’s the real deal. well respected in the community

i am researching jb4 because the logging portion of it is interesting to me as a programmer

i wouldn’t put a jb4 on my car if you paid me $20,000
works for some people but, not worth it to me

AlexZTuned

If you want to log, I would recommend purchasing the HPTuners MPVI2 ($300): https://www.hptuners.com/mpvi2/#custom_form_mpvi2

It’s compatible with our vehicles and you can use HP tuners free logging software along with the OBD dongle. Much better than JB4 where you’re dumping out a CSV and you have to visualize the data yourself or upload it to get a graph with the PID’s. Much more user friendly and they have great logging software.

It’s a lot cheaper than JB4 for logging and HP Tuners is not only well respected with a great reputation, they’ve been around for ages (since the early 2000’s).

MuffinFlavored

are you sure it works with m177/m178 engines? i looked and saw it was not officially supported by hptuners

AlexZTuned

Yes, positive. You can reach out to them directly to confirm, but there are already a handful of people that are using this to log their W205.

MuffinFlavored

awesome man, thanks. do you know if it works out of the box with w205 or is some kind of special file/mappack needed to make it work?

BMS

HP Tuners is great but to clear up some misinformation the JB4 app pops out instant charts or open logs in the free JB4 windows software for quick and easy visualization.

I finally dyno-ed my car last Friday. Ambient temps were in the high 90s. Runs were in 4th gear. Figured it's high time some data for C63s owners is put out there. Bear in mind that the runs were done on the (heartbreak) Mustang Dyno.

Map5 - 7psi peak request over stock, less taper to redline - E30

Map0- Stock operation, JB4 disabled - 93 octane

Map 3 6psi peak over stock, less taper to redline - 93 octane

Mods: JB4, Pedal Tuner, secondary CAT delete.
First run - Map0, 93 octane
Second run - Map3 93 octane
Third run - Map5 E30 (left and went to put Ethanol in tank and came back to the same shop within 20 minutes of first two runs)

tobeit

Do I see that correct, you gain about 50-60 whp?

AMGMessiah

65 rwhp and 105 rwtq gain from stock (secondary cat delete) to JB4 E30. Not too shabby for a piggy-back.

MuffinFlavored

how reliable is your map 3 6psi over stock 93 octane map? no misfires?
